Fun Ocean Planet Facts I love learning for my book

A water planet needs a strong magnetic field to protect its atmosphere, otherwise greenhouse gases will cause the planet to heat up over time, the ocean to boil, and vapour to escape into space via solar wind (like Venus and Mars)

Gas giants like Jupiter and Saturn, thought to lack surfaces and have a stratum of liquid nitrogen.

Although still not fully understood, ice giants like Uranus and Neptune have hot, highly compressed, supercritical water. However, the "ocean" on Neptune, might actually be liquid diamond.

There are currently five known water planets in habitable zones. Kepler-22b "Super Earth" is 2.4 times the size of Earth. It is currently unknown if it has a rocky, gaseous or liquid composition, but it does have clouds.

Kepler-453b is 60% bigger than Earth, orbiting a star 10% larger than our sun and 20% brighter. The temperature is warm enough to have an ocean and house life.

Kepler-62 has five planets orbiting a star 2/3 the size of our sun and only 1/5 as bright. At 7 billion years old it is older than our solar system and two of the planets are habitable zones and 40% larger than Earth.

HAT-P-11b is a planet the size of Neptune, making it the smallest exoplanet to have water, it sits so close to its sun in a five-day orbit, it's too warm to have an ocean, but it still has water vapour and cloudless skies.

Ganymede (Jupiter's largest moon) proves that satellites can have their own magnetic field and underground saltwater oceans.

Callisto, Jupiter's second largest moon, is equal parts rock and ice with the lowest density of any moon. Its structure is composed of an icy-rock crater exterior, a thin saltwater secondary layer, and finally an ice-rock core.

Enceladus, Saturn's sixth largest moon, is covered in a thin smooth sheet of ice, making it the most reflective body in our solar system. It also has an underground ocean, with venting plumes of water vapour escaping into space from giant fissures in its southern pole that are so big the moon looks like it has tiger stripes.

Titan, Saturn's largest moon, has the saltiest subsurface ocean of any moon. It's currently unknown if Titan's ocean is a very thin layer sandwiched between sheets of ice, or if it extends all the way down to its rocky interior. There are lakes and rivers visible on Titan's surface, but it's not saltwater, its liquid hydrocarbons (methane and ethane)

Triton, one of Neptune's moons, has active geysers that spew nitrogen into the atmosphere, and volcanic fixtures cover the icy rock surface, most likely the result of past tidal heating.

Dwarf Planet Pluto has mountains of water ice and flowing glaciers of nitrogen and methane ice. Mysterious fault lines, some hundreds of miles long, suggest that Pluto has a hidden subsurface ocean.

Close to the summit of an underwater mountain near the Mid-Atlantic Ridge is where the Lost City Hydrothermal Field exits. Jagged towers, bathed in ghostly blue light, tell a story of discovery, resilience, and impending threats.

Discovered in 2000, the Lost City Hydrothermal Field lies over 700 metres beneath the ocean surface, shrouded in mystery. This venting environment, enduring for at least 120,000 years, testifies to the unique interaction of the upthrusting mantle with seawater, a saga unparalleled in the ocean's depths.

Despite its extreme locale, life thrives in the Lost City. The vents release hydrogen, methane, and gases that sustain thriving microbial communities in the absence of oxygen, according to Science Alert. From snails to crustaceans, an range of creatures live in its chimneys, showcasing the adaptability of life in unconventional ecosystems.

A glimpse into extraterrestrial habitats

The hydrocarbons emanating from the Lost City's vents spark intrigue, suggesting a potential parallel to extraterrestrial habitats.

Scientists ponder the question of life's origin in analogous environments, speculating about the possibilities on celestial bodies such as Enceladus, Europa, or Mars.

In stark contrast to black smokers, traditional underwater volcanic vents, the Lost City's calcite vents defy expectations. They produce copious amounts of hydrogen and methane, diverging from the mineral-rich emissions of black smokers. The sheer size of these vents hints at a storied history and prolonged activity.

Mining threatens this habitat

The allure of the Lost City extends beyond scientific fascination, attracting commercial interests. In 2018, Poland secured mining rights around the area, posing a substantial threat to this delicate ecosystem. Scientists raise alarm about potential plumes and discharges from mining activities, urging for the Lost City's protection.

Urgent calls resonate for its designation as a World Heritage site, a plea to shield this underwater marvel from the irreversible impacts of mining and environmental degradation.

Comet, Meteor, Asteroid? Vestra OCs Edition

Nothing is cooler than being compared to astrological bodies.

Rosamund:

Comet

Congratulations! You are a comet. As a comet, some may see you as mysterious or unpredictable. Really, you're just busy. You tend to prefer following schedules, and be a leader when in team situations. To the people who know you well, you are independent and strong, with a passion for success and attention. So what is a comet, actually? Comets are made up of ice, dust, rock, and organic materials, and they orbit around the sun in a long, oval shape. Comets also have tails, which are due to flying closer to the sun, where the ice begins to vaporize, leaving a trail of leftover rubble and ice. As well as the tail, comets have what's called a coma, which is the fuzzy, cloud-like glow around the comet made up of methane, ammonia, and ice. Comets are said to have come from the Oort Cloud, a region outside Pluto where it is rumoured a million comets are, and the Kuiper Belt, where trillions of comets orbit the sun.

Tancred:

Asteroid

Congratulations! You are an asteroid. As an asteroid, you like to be around people, and work well in groups. You have the ability to make friends easy, due to your social and energetic personality. You are an original, unique person, who is capable of big things! Some people say you can be stubborn, too, but that's just because you are so loyal. You are also very adaptable, and may take change in life cautiously, yet willingly. So, what's an asteroid, really? Asteroids have been around since the creation of our solar system, so about 4.6 billion years. They are made up of metals, rock, rubble, and some even contain water. They are solid objects. The majority of asteroids in our solar system are found in the Asteroid Belt, and the others like to orbit in groups, and in shorter, circular shapes. Many of these orbits are unusual or random. Very rarely, asteroids will have tails, like a comet does. This only occurs when an asteroid is hit by another, and as a result, emits dust and ice. Asteroids also become meteors when they enter the Earth's atmosphere.

Medee:

Meteor

Congratulations! You are a meteor! As a meteor, people appreciate the kindness and loyalty you give. You are an intelligent, quiet person with big hopes and dreams that some may say are... out of this world. You are supportive of others and easy-going. Some people may not approach you because of your independent nature, but the people who are close to you know you're more than what's on the surface. So what's a meteor, really? Meteors come from the remains of a comet trail, so they are mad up of dust and ice. They orbit the sun, but travel alone. Meteors also burn up in the Earth's atmosphere, making them so bright, we can see them with our naked eyes. Some people call meteors "shooting stars" because of this. There are three types of meteors, depending on what they are made up of: stony, iron, and stony-iron. 99.8% of meteors that pass through our atmosphere are originally asteroids, but the remaining 0.2% come from the moon or Mars.

A Lethal Laugh and the Methane Marvel

In the dim light of a mead hall that smelled of burnt meat and unwashed heroes, I, Beowulf, sat in a moment of rare contemplation. After a lifetime of hewing monsters and engaging in brawls that would make mere mortals blanch, I found myself in an unexpected quandary. You see, one does not simply slay Grendel and retire to a life of plowshares and quietude. The lust for battle, the thrill of the chase, they linger, like the odor of dragon fire on a windless day. And so, when the chance arose to combat a new foe—not of flesh and bone but of gas and mystery—I seized it with the fervor of a berserker charging into the fray.

But I am getting ahead of myself. The tale begins, as all great tales do, with a fart.

It was after a particularly boisterous feast, the kind where men drink themselves into visions of glory and women pretend not to notice. Suddenly, a sound rang out—nay, it bellowed like the war cry of a dozen men at once. This was no ordinary flatulence. It reverberated through the hall with the force of a Gjallarhorn, scattering hounds and terrifying lesser warriors into fits of nervous laughter.

As the laughter died down, I could not help but ponder the cause of such an auditory marvel. What unholy diet could produce such a noxious blast? My thoughts drifted to the mysterious odors that sometimes wafted over from the marshes, where Grendel once dwelled. But no, Grendel was long gone, his arm mounted like a trophy on the wall. Could it be that Mars—the Red Planet itself—had its own breed of gaseous monsters lurking beneath its barren surface?

Mars, the celestial neighbor we’d stared at with such awe and wonder. In my mind’s eye, I saw it not as a distant, desolate world, but as a battlefield, its red sands ripe for conquest. And so, I made it my mission to unravel this mystery. If foul gas could spew from a man’s gut, who’s to say that Mars, with its fiery surface, did not harbor some monstrous belcher of methane beneath?

With the resolve of a hero whose weapon never rests, I dove into the annals of modern knowledge—or as close as one gets in this realm of books and scrolls. I learned of a mighty band of scholars who had observed methane on Mars, like the fiery breath of a dragon rousing from slumber. They called it a sign, a rune of some hidden activity, possibly life, or a beast of stone and soil. And I, Beowulf, could think of no quest more worthy.

Methane—this fiendish vapor—was as elusive as any monster I had faced. On Earth, it could be traced to both the belching of cows and the festering of swamps. But on Mars? Was it the exhalation of some ancient, unseen lifeform? Or perhaps the result of titanic geological clashes beneath the surface? The thought of battling a dragon of gas rather than scale sent a thrill down my spine.

Thus, armed with the knowledge of these scientists and the metaphorical sword of inquiry, I set forth on this new quest. The scholars’ tools—spectrometers, rovers, and other contraptions—became my weapons, their discoveries my battle tactics. I would wrestle this mystery as I once did Grendel, and just as that fiend fell, so too would this Martian miasma.

And so, dear reader, I present to you the fruits of this unexpected journey. In the story that follows, you will join me in exploring the depths of Mars, where the red sands hide secrets as old as time and as volatile as the gas that brought us here. Methane—whether a clue to life, a geological whisper, or the breath of some slumbering beast—shall meet the might of Beowulf. I invite you to take up arms alongside me, as we uncover what lies beneath the Red Planet’s surface, not with swords and shields, but with the piercing gaze of science and the courage to confront the unknown.

Metaphysical Uncovering the Mysterious Things in the Ocean We Still Don’t Know

Let’s see how the ocean floor remains largely unexplored, with only a small percentage of it mapped in detail. Ongoing efforts aim to improve our understanding of the mysterious things in the oceans.

The ocean’s floor:-

Before swimming this summer, remember that a lot is going on under the sea that we need to learn about. The Metaphysical show is remote viewing and investigating the weirdest and most mysterious things in the ocean that scientists haven’t solved yet.

Seventy per cent of the Earth’s surface is beneath the ocean, yet ninety-five per cent of it remains undiscovered by humans. Although it is commonly stated that we know more about the surface of Mars than we do about the ocean floor, scientists have been able to map all of the ocean floor — but the resolution is quite low, so we can only see things larger than three miles.

Ongoing research, such as Seabed 2030, intends to bring the ocean floor into sharper focus, allowing us to better view and understand what’s down there. For the time being, we may simply enjoy the world’s most breathtaking deep-sea world.

Milky Sea Phenomenon:-

For hundreds of years, mariners have described witnessing a weird “milky” glow from the sea as far as the eye can see, but experts have been unable to explain it — or even determine whether it was real. In 2006, researchers were able to acquire a satellite photograph of a milky sea, and a few years later, studies revealed that the glow was most likely caused by bioluminescent bacteria that attract fish and thrive in their bellies.

However, scientists are still unsure how or why the bacteria assemble in such large quantities that they can be observed from space. Furthermore, their glow is constant, as opposed to the more typical “dinoflagellate” species, which emit transient bursts of light.

The Strangeness of the Bermuda Triangle:-

The Bermuda Triangle is made up of three points: Miami, the island of Puerto Rico, and Bermuda — but don’t panic if you’ve already planned a trip to one of them. Despite the area’s reputation for mysterious ship and plane disappearances, there is no proof that it is more dangerous than any other global location, or that a supernatural phenomenon is at work.

However, the National Oceanic and Atmospheric Administration (NOAA) admits that there may be scientific causes for the disappearances, such as the possibility of hurricanes, rapid weather changes caused by the Gulf Stream, and the Caribbean’s numerous islands, which make navigation difficult.

NOAA also acknowledges that the area may have interfered with navigational equipment, causing them to indicate true north rather than magnetic north, and that “oceanic flatulence,” a blast of methane gas from the sea, may have damaged vessels and planes.

Giant Squid:-

This massive animal could be the legendary Kraken from Pirates of the Caribbean and Jules Verne’s 20,000 Leagues Under the Sea. Although it is improbable that the enormous squid assaulted ships, nothing is known about this fascinating creature from the depths. It wasn’t even photographed alive until 2004, and it wasn’t filmed until several years later when it was discovered on the surface.

Undersea video was not completed until 2012. Scientists know almost nothing about the lives of these deep-sea giants, including their size, which some believe can reach 66 feet. Only their cousin, the colossal squid, may be larger in weight, but not in length, and even less is known about them.

Subsea geology:-

We may not know much about ocean geography, but what we have seen is just as beautiful as what we see on land — and may even be shockingly similar. “Brine pools,” where the salt water concentration is higher than the surrounding ocean, form lake-like surfaces and shorelines. The world’s tallest waterfall is underwater in the Denmark Strait, where cold water cascades over a massive drop in the ocean floor, plummeting 11,500 feet (the largest land waterfall is just 3,212 feet).

Underwater volcanoes erupt — the greatest one ever recorded occurred recently, and scientists nearly missed it. Although experts are aware that all of these phenomena exist, their specific mechanisms are still being explored, making them one of the most intriguing scientific mysteries yet to be solved.

Blue whales:-

These mysterious marine monsters are the largest animals that have ever lived on Earth. However, due to the whaling trade, which hunted them nearly to extinction, as well as their delayed reproduction, there aren’t many of them to examine. As a result, nothing is known about these elusive organisms, such as their lifespan, sexual development, and reproductive methods. The creatures’ timidity makes them difficult to watch. In 2017, a video of never-before-seen blue whale activity off Sri Lanka sparked debate among experts about whether the rolling and racing seen on camera was a mating ritual. The researchers intend to return this summer to see what they can learn.

Mariana Trench:-

This location in the water off the Mariana Islands close to Guam is the deepest place on Earth, nearly seven miles down. In comparison, Mount Everest is only 5.5 miles tall. This little-explored section of the sea has only been seen by three people: two oceanographers in 1960 and filmmaker/ocean explorer James Cameron in 2012 on his first solo voyage. The trench is dark, only a few degrees above freezing, and under extreme pressure of eight tons per square inch.

However, marine life has survived, if not thrived, in such a harsh environment. However, more research into the ecosystem’s unique characteristics is required.

Even though it is distant, it is not immune to pollution: researchers discovered a plastic bag in a database of trench photos earlier this year. Unfortunately, pollution impacts some of the world’s most beautiful natural beauties.

Final Concluding Thoughts:-

This article briefly overviews some of the primary reasons for and against nuclear power. Reflect on each, conduct your study, and determine whether atomic energy is a feasible replacement for fossil fuels.

The article doesn’t definitively say nuclear power is the best option, but it highlights its potential as a clean energy source.

Challenges like safety concerns, waste disposal, and costs remain. Overall, it emphasizes the need for a balanced discussion on nuclear power transitioning away from fossil fuels.

Neither water nor atmosphere

Neither water nor atmosphere, the surface is filled with only 95% carbon dioxide, 

that red planet. Mars is called red planet 

because the entire planet is covered with rusty dust. 

Where there is no sign of oxygen and water, how does rust and iron dust form there? Carbon is produced because burning turns into ash. 

But on Mars, oxygen is only 0.13%, yet carbon dioxide is 95%. 

Can carbon dioxide be present in large quantities due to any process other than reaction with oxygen? 

Venus also has large quantities of carbon dioxide.

2.5 billion years ago, the earth also had an atmosphere of carbon dioxide. 

It is said that there is no oxygen anywhere in the solar system. 

Even in space, there is no oxygen. 

Mars does not have it. 

How can carbon dioxide be present on Mars apart from oxygen?

The Martian atmosphere is an oxidized atmosphere. The photochemical reactions in the atmosphere tend to oxidize the organic species and turn them into carbon dioxide or carbon monoxide.

With Mars Methane Mystery Unsolved, Curiosity Serves Scientists a New One: Oxygen

For the first time in the history of space exploration, scientists have measured the seasonal changes in the gases that fill the air directly above the surface of Gale Crater on Mars. As a result, they noticed something baffling: oxygen, the gas many Earth creatures use to breathe, behaves in a way that so far scientists cannot explain through any known chemical processes.

Over the course of three Mars years (or nearly six Earth years) an instrument in the Sample Analysis at Mars (SAM) portable chemistry lab inside the belly of NASA’s Curiosity rover inhaled the air of Gale Crater and analyzed its composition. The results SAM spit out confirmed the makeup of the Martian atmosphere at the surface: 95% by volume of carbon dioxide (CO2), 2.6% molecular nitrogen (N2), 1.9% argon (Ar), 0.16% molecular oxygen (O2), and 0.06% carbon monoxide (CO). They also revealed how the molecules in the Martian air mix and circulate with the changes in air pressure throughout the year. These changes are caused when CO2 gas freezes over the poles in the winter, thereby lowering the air pressure across the planet following redistribution of air to maintain pressure equilibrium. When CO2 evaporates in the spring and summer and mixes across Mars, it raises the air pressure.

Within this environment, scientists found that nitrogen and argon follow a predictable seasonal pattern, waxing and waning in concentration in Gale Crater throughout the year relative to how much CO2 is in the air. They expected oxygen to do the same. But it didn’t. Instead, the amount of the gas in the air rose throughout spring and summer by as much as 30%, and then dropped back to levels predicted by known chemistry in fall. This pattern repeated each spring, though the amount of oxygen added to the atmosphere varied, implying that something was producing it and then taking it away.

“The first time we saw that, it was just mind boggling,” said Sushil Atreya, professor of climate and space sciences at the University of Michigan in Ann Arbor. Atreya is a co-author of a paper on this topic published on November 12 in the Journal of Geophysical Research: Planets.

As soon as scientists discovered the oxygen enigma, Mars experts set to work trying to explain it. They first double- and triple-checked the accuracy of the SAM instrument they used to measure the gases: the Quadrupole Mass Spectrometer. The instrument was fine. They considered the possibility that CO2 or water (H2O) molecules could have released oxygen when they broke apart in the atmosphere, leading to the short-lived rise. But it would take five times more water above Mars to produce the extra oxygen, and CO2 breaks up too slowly to generate it over such a short time. What about the oxygen decrease? Could solar radiation have broken up oxygen molecules into two atoms that blew away into space? No, scientists concluded, since it would take at least 10 years for the oxygen to disappear through this process.

“We’re struggling to explain this,” said Melissa Trainer, a planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland who led this research. “The fact that the oxygen behavior isn’t perfectly repeatable every season makes us think that it’s not an issue that has to do with atmospheric dynamics. It has to be some chemical source and sink that we can’t yet account for.”

To scientists who study Mars, the oxygen story is curiously similar to that of methane. Methane is constantly in the air inside Gale Crater in such small quantities (0.00000004% on average) that it’s barely discernable even by the most sensitive instruments on Mars. Still, it’s been measured by SAM’s Tunable Laser Spectrometer. The instrument revealed that while methane rises and falls seasonally, it increases in abundance by about 60% in summer months for inexplicable reasons. (In fact, methane also spikes randomly and dramatically. Scientists are trying to figure out why.)

With the new oxygen findings in hand, Trainer’s team is wondering if chemistry similar to what’s driving methane’s natural seasonal variations may also drive oxygen’s. At least occasionally, the two gases appear to fluctuate in tandem.

“We’re beginning to see this tantalizing correlation between methane and oxygen for a good part of the Mars year,” Atreya said. “I think there’s something to it. I just don’t have the answers yet. Nobody does.”

Oxygen and methane can be produced both biologically (from microbes, for instance) and abiotically (from chemistry related to water and rocks). Scientists are considering all options, although they don’t have any convincing evidence of biological activity on Mars. Curiosity doesn’t have instruments that can definitively say whether the source of the methane or oxygen on Mars is biological or geological. Scientists expect that non-biological explanations are more likely and are working diligently to fully understand them.

Trainer’s team considered Martian soil as a source of the extra springtime oxygen. After all, it’s known to be rich in the element, in the form of compounds such as hydrogen peroxide and perchlorates. One experiment on the Viking landers showed decades ago that heat and humidity could release oxygen from Martian soil. But that experiment took place in conditions quite different from the Martian spring environment, and it doesn’t explain the oxygen drop, among other problems. Other possible explanations also don’t quite add up for now. For example, high-energy radiation of the soil could produce extra O2 in the air, but it would take a million years to accumulate enough oxygen in the soil to account for the boost measured in only one spring, the researchers report in their paper.

“We have not been able to come up with one process yet that produces the amount of oxygen we need, but we think it has to be something in the surface soil that changes seasonally because there aren’t enough available oxygen atoms in the atmosphere to create the behavior we see,” said Timothy McConnochie, assistant research scientist at the University of Maryland in College Park and another co-author of the paper.

The only previous spacecraft with instruments capable of measuring the composition of the Martian air near the ground were NASA’s twin Viking landers, which arrived on the planet in 1976. The Viking experiments covered only a few Martian days, though, so they couldn’t reveal seasonal patterns of the different gases. The new SAM measurements are the first to do so. The SAM team will continue to measure atmospheric gases so scientists can gather more detailed data throughout each season. In the meantime, Trainer and her team hope that other Mars experts will work to solve the oxygen mystery.

“This is the first time where we’re seeing this interesting behavior over multiple years. We don’t totally understand it,” Trainer said. “For me, this is an open call to all the smart people out there who are interested in this: See what you can come up with.”

12 नवंबर 2019

मंगल ग्रह के मीथेन रहस्य का पता न चलने पर, क्यूरियोसिटी ने वैज्ञानिकों को एक नया सुराग दिया: ऑक्सीजन

अंतरिक्ष अन्वेषण के इतिहास में पहली बार, वैज्ञानिकों ने मंगल ग्रह पर गेल क्रेटर की सतह के ठीक ऊपर हवा में भरी गैसों में मौसमी परिवर्तनों को मापा है। परिणामस्वरूप, उन्होंने कुछ चौंकाने वाली बात देखी: ऑक्सीजन, वह गैस जिसका उपयोग पृथ्वी के कई जीव सांस लेने के लिए करते हैं, इस तरह से व्यवहार करती है जिसे अब तक वैज्ञानिक किसी भी ज्ञात रासायनिक प्रक्रिया के माध्यम से नहीं समझा पाए हैं।

तीन मंगल वर्षों (या लगभग छह पृथ्वी वर्षों) के दौरान नासा के क्यूरियोसिटी रोवर के पेट के अंदर मंगल ग्रह पर नमूना विश्लेषण (एसएएम) पोर्टेबल रसायन विज्ञान प्रयोगशाला में एक उपकरण ने गेल क्रेटर की हवा में साँस ली और इसकी संरचना का विश्लेषण किया। एसएएम ने जो परिणाम निकाले, उनसे सतह पर मंगल ग्रह के वायुमंडल की संरचना की पुष्टि हुई: मात्रा के हिसाब से 95% कार्बन डाइऑक्साइड (CO2), 2.6% आणविक नाइट्रोजन (N2), 1.9% आर्गन (Ar), 0.16% आणविक ऑक्सीजन (O2), और 0.06% कार्बन मोनोऑक्साइड (CO)। उन्होंने यह भी बताया कि मंगल ग्रह की हवा में अणु पूरे वर्ष हवा के दबाव में बदलाव के साथ कैसे मिलते और घूमते हैं। ये परिवर्तन तब होते हैं जब सर्दियों में ध्रुवों पर CO2 गैस जम जाती है इस वातावरण में, वैज्ञानिकों ने पाया कि नाइट्रोजन और आर्गन एक पूर्वानुमानित मौसमी पैटर्न का पालन करते हैं, जो हवा में मौजूद CO2 की मात्रा के सापेक्ष पूरे वर्ष गेल क्रेटर में सांद्रता में वृद्धि और कमी करता है। उन्हें उम्मीद थी कि ऑक्सीजन भी ऐसा ही करेगी। लेकिन ऐसा नहीं हुआ। इसके बजाय, वसंत और गर्मियों के दौरान हवा में गैस की मात्रा 30% तक बढ़ गई, और फिर गिरावट में ज्ञात रसायन विज्ञान द्वारा अनुमानित स्तरों पर वापस गिर गई। यह पैटर्न हर वसंत में दोहराया जाता है, हालांकि वातावरण में शामिल ऑक्सीजन की मात्रा अलग-अलग होती है, जिसका अर्थ है कि कुछ इसे पैदा कर रहा था और फिर इसे दूर ले जा रहा था।

एन आर्बर में मिशिगन विश्वविद्यालय में जलवायु और अंतरिक्ष विज्ञान के प्रोफेसर सुशील आत्रेय ने कहा, "पहली बार जब हमने यह देखा, तो यह आश्चर्यजनक था।" आत्रेय 12 नवंबर को जर्नल ऑफ जियोफिजिकल रिसर्च: प्लैनेट्स में प्रकाशित इस विषय पर एक पेपर के सह-लेखक हैं। जैसे ही वैज्ञानिकों ने ऑक्सीजन की पहेली को खोजा, मंगल ग्रह के विशेषज्ञों ने इसे समझाने की कोशिश में काम करना शुरू कर दिया। उन्होंने सबसे पहले गैसों को मापने के लिए इस्तेमाल किए जाने वाले SAM उपकरण की सटीकता की दोहरी और तिहरी जांच की: क्वाड्रुपोल मास स्पेक्ट्रोमीटर। उपकरण ठीक था। उन्होंने इस संभावना पर विचार किया कि CO2 या पानी (H2O) के अणु वायुमंडल में टूटने पर ऑक्सीजन छोड़ सकते हैं, जिससे अल्पकालिक वृद्धि हो सकती है। लेकिन अतिरिक्त ऑक्सीजन का उत्पादन करने के लिए मंगल के ऊपर पाँच गुना अधिक पानी की आवश्यकता होगी, और CO2 इतनी कम समय में इसे बनाने के लिए बहुत धीमी गति से टूटती है। ऑक्सीजन में कमी के बारे में क्या? क्या सौर विकिरण ने ऑक्सीजन के अणुओं को दो परमाणुओं में तोड़ दिया होगा जो अंतरिक्ष में उड़ गए? नहीं, वैज्ञानिकों ने निष्कर्ष निकाला, क्योंकि इस प्रक्रिया के माध्यम से ऑक्सीजन को गायब होने में कम से कम 10 साल लगेंगे। मैरीलैंड के ग्रीनबेल्ट में नासा के गोडार्ड स्पेस फ़्लाइट सेंटर की ग्रह वैज्ञानिक मेलिसा ट्रेनर ने कहा, "हम इसे समझाने के लिए संघर्ष कर रहे हैं।" "यह तथ्य कि ऑक्सीजन का व्यवहार हर मौसम में पूरी तरह से दोहराया नहीं जा सकता है, हमें लगता है कि यह कोई ऐसा मुद्दा नहीं है जिसका वायुमंडलीय गतिशीलता से कोई लेना-देना है। यह कुछ रासायनिक स्रोत और सिंक होना चाहिए जिसका हम अभी तक हिसाब नहीं लगा पाए हैं।" मंगल ग्रह का अध्ययन करने वाले वैज्ञानिकों के लिए, ऑक्सीजन की कहानी मीथेन की कहानी से काफी मिलती-जुलती है। मीथेन लगातार गेल क्रेटर के अंदर हवा में इतनी कम मात्रा में (औसतन 0.00000004%) मौजूद है कि मंगल पर सबसे संवेदनशील उपकरणों द्वारा भी इसे पहचान पाना मुश्किल है। फिर भी, इसे SAM के ट्यूनेबल लेजर स्पेक्ट्रोमीटर द्वारा मापा गया है। उपकरण ने खुलासा किया कि मीथेन मौसमी रूप से बढ़ता और घटता है, लेकिन गर्मियों के महीनों में यह अस्पष्ट कारणों से लगभग 60% तक बढ़ जाता है। (वास्तव में, मीथेन भी अनियमित रूप से और नाटकीय रूप से बढ़ता है। वैज्ञानिक इसका कारण जानने की कोशिश कर रहे हैं।) ऑक्सीजन के नए निष्कर्षों के साथ, ट्रेनर की टीम सोच रही है कि क्या मीथेन के प्राकृतिक मौसमी बदलावों को चलाने वाले रसायन विज्ञान के समान ही ऑक्सीजन के भी कारक हो सकते हैं। कम से कम कभी-कभी, दोनों गैसें ��क साथ उतार-चढ़ाव करती दिखाई देती हैं। अत्रेय ने कहा, "हम मंगल वर्ष के एक बड़े हिस्से के लिए मीथेन और ऑक्सीजन के बीच इस लुभावने संबंध को देखना शुरू कर रहे हैं।" "मुझे लगता है कि इसमें कुछ है। मेरे पास अभी तक इसका उत्तर नहीं है। किसी के पास नहीं है।" ऑक्सीजन और मीथेन जैविक रूप से (उदाहरण के लिए, सूक्ष्मजीवों से) और अजैविक रूप से (पानी और चट्टानों से संबंधित रसायन विज्ञान से) दोनों तरह से उत्पादित किए जा सकते हैं। वैज्ञानिक सभी विकल्पों पर विचार कर रहे हैं, हालांकि उनके पास मंगल पर जैविक गतिविधि का कोई ठोस सबूत नहीं है। क्यूरियोसिटी के पास ऐसे उपकरण नहीं हैं जो निश्चित रूप से कह सकें कि मंगल पर मीथेन या ऑक्सीजन का स्रोत जैविक है या भूवैज्ञानिक। वैज्ञानिकों को उम्मीद है कि गैर-जैविक स्पष्टीकरण अधिक संभावित हैं और वे उन्हें पूरी तरह से समझने के लिए लगन से काम कर रहे हैं।

ट्रेनर की टीम ने मंगल ग्रह की मिट्टी को वसंत ऋतु में मिलने वाली अतिरिक्त ऑक्सीजन का स्रोत माना। आखिरकार, यह हाइड्रोजन पेरोक्साइड और परक्लोरेट्स जैसे यौगिकों के रूप में तत्व से भरपूर मानी जाती है। वाइकिंग लैंडर्स पर दशकों पहले किए गए एक प्रयोग से पता चला कि गर्मी और नमी मंगल ग्रह की मिट्टी से ऑक्सीजन छोड़ सकती है। लेकिन वह प्रयोग मंगल ग्रह के वसंत ऋतु के वातावरण से काफी अलग परिस्थितियों में हुआ था, और यह अन्य समस्याओं के अलावा ऑक्सीजन की कमी की व्याख्या नहीं करता है। अन्य संभावित व्याख्याएँ भी अभी पूरी तरह से सही नहीं हैं। उदाहरण के लिए, मिट्टी का उच्च-ऊर्जा विकिरण हवा में अतिरिक्त O2 उत्पन्न कर सकता है, लेकिन मिट्टी में पर्याप्त ऑक्सीजन जमा होने में दस लाख साल लगेंगे, जो केवल एक वसंत में मापी गई वृद्धि के लिए जिम्मेदार होगी, शोधकर्ताओं ने अपने शोधपत्र में बताया। यूनिवर्सिटी ऑफ मैरीलैंड इन कॉलेज पार्क के सहायक अनुसंधान वैज्ञानिक और पेपर के एक अन्य सह-लेखक टिमोथी मैककोनोची ने कहा, "हम अभी तक एक भी ऐसी प्रक्रिया नहीं खोज पाए हैं जो हमें आवश्यक मात्रा में ऑक्सीजन पैदा कर सके, लेकिन हमें लगता है कि यह सतह की मिट्टी में कुछ ऐसा होना चाहिए जो मौसमी रूप से बदलता हो क्योंकि वायुमंडल में पर्याप्त ऑक्सीजन परमाणु उपलब्ध नहीं हैं जो हमारे द्वारा देखे जाने वाले व्यवहार को बना सकें।" धरती के पास मंगल ग्रह की हवा की संरचना को मापने में सक्षम उपकरणों के साथ एकमात्र पिछला अंतरिक्ष यान नासा के जुड़वां वाइकिंग लैंडर थे, जो 1976 में ग्रह पर पहुंचे थे। हालांकि, वाइकिंग प्रयोगों ने केवल कुछ मंगल ग्रह के दिनों को कवर किया, इसलिए वे विभिन्न गैसों के मौसमी पैटर्न को प्रकट नहीं कर सके। नए SAM माप ऐसा करने वाले पहले हैं। SAM टीम वायुमंडलीय गैसों को मापना जारी रखेगी ताकि वैज्ञानिक प्रत्येक मौसम में अधिक विस्तृत डेटा एकत्र कर सकें। इस बीच, ट्रेनर और उनकी टीम को उम्मीद है कि अन्य मंगल विशेषज्ञ ऑक्सीजन रहस्य को सुलझाने के लिए काम करेंगे। ट्रेनर ने कहा, "यह पहली बार है जब हम कई वर्षों में इस दिलचस्प व्यवहार को देख रहे हैं। हम इसे पूरी तरह से समझ नहीं पाए हैं।" "मेरे लिए, यह उन सभी बुद्धिमान लोगों के लिए एक खुला आह्वान है जो इसमें रुचि रखते हैं: देखें कि आप क्या कर सकते हैं।" लोनी शेखटमैन द्वारा नासा का गोडार्ड स्पेस फ़्लाइट सेंटर, ग्रीनबेल्ट, मैरीलैंड।

Rovers have roamed its alien terrain, scooping up rock samples and searching for signs of microbial life in basins once awash with water.

But in the nearly 30 years that NASA has been sending small robotic vehicles to Mars—the space agency’s Jet Propulsion Laboratory has operated five rovers on the red planet since 1997—the probes, inching along at a turtle-like pace, have explored only a small portion of the dusty, cold, desert world. 

Now, a University of Miami College of Engineering researcher has designed a new Mars explorer that will be faster and more advanced than any other that has ever probed the planet. 

GeCheng Zha’s Mars Aerial Ground and Global Intelligent Explorer, or MAGGIE, is not a land rover at all, but a solar-powered, remote-controlled electric fixed-wing airplane that will soar 3,280 feet in the air, reach a top speed of 135 miles per hour, and take off and land vertically, deploying a suite of sophisticated scientific instruments that could help solve some of the mysteries of Mars. 

Science fiction? Make-believe? Far from it. 

MAGGIE, which would have solar panels mounted atop its 26-foot wingspan, is closer to reality than not. Zha is perfecting electric vertical take-off and landing (eVTOL) technology that would minimize power consumption by generating lift from the innovative aircraft’s wings and propellers. 

“It’s deflected slipstream technology enabled by a co-flow jet airfoil, and a series of micro-compressors embedded into the wings is the key to its success,” said Zha, a professor of aerospace engineering and director of the Aerodynamics and Computational Fluid Dynamics Lab at the College of Engineering. “Those micro-compressors suck in, pressurize, and then expel air to achieve ultra-high lift with virtually stall-free operation. The micro-compressors also work in tandem with a propulsion system to create thrust.” 

He has tested a prototype of the wing at Virginia-based Advanced Aircraft Company and at NASA.. “It has performed exceptionally well,” said Zha, noting that the wing will help MAGGIE achieve lift far superior to conventional aircraft on Earth. That greater lift coefficient, he explained, will allow the aircraft to overcome the thin atmosphere on Mars as well as its significantly lower gravity, which is one-third that of Earth’s. 

The aircraft wouldn’t fly to Mars, but would hitch a ride aboard a powerful rocket, much like the Perseverance rover rode atop an Atlas rocket that blasted off from Kennedy Space Center in Florida on July 30, 2020. 

Once deployed, MAGGIE would survey the entire landscape of the red planet, traveling more than 100 miles on a full battery charge and landing in certain areas to conduct atmospheric and geophysical experiments. Among its potential scientific missions: a study of the origin of the Martian core dynamo from the weak magnetic fields found in large impact basins, an investigation of the source of methane signals detected in the planet’s Gale crater, and mapping of subsurface water ice in the mid-latitudes, where it has been observed from orbit. 

Ingenuity, a small autonomous helicopter transported to the surface of Mars while attached to the belly of Perseverance, which landed on the red planet nearly seven months after it left Earth, inspired Zha to come up with the idea for MAGGIE. 

The first aircraft to fly on Mars, Ingenuity was originally designed to perform up to five experimental test flights over 30 days. But the little helicopter that could exceeded expectations, making 72 flights over three years and flying more than 14 times farther than planned before a damaged rotor ended its mission.

Ingenuity covered only about 11 miles during its three years of operation. MAGGIE, according to Zha, would cover nearly 10,000 miles over the course of a Martian year—687 days. 

“We still must do a lot more testing, specifically under simulated Mars-like conditions. So, a prototype of a full-scale aircraft is still a long way in the future,” Zha said. 

Phase I funding from the NASA Innovative Advanced Concepts Program will allow Zha to continue developing MAGGIE. 

“But our goal is to make history—the first fixed-wing aircraft to fly on the red planet,” the researcher said. “Even though it is more of a concept right now, we’re excited about the aircraft’s potential to expand humanity’s ability to explore Mars.”

Mars Exploration: Uncovering the Mysteries of the Red Planet

Humans have always been fascinated by the universe and the celestial bodies it holds. Our neighboring planet, Mars, has captivated the imagination of scientists, astronomers, and researchers alike. With its rust-colored landscape, it has been a subject of intrigue and study for centuries. In recent years, technological advancements have allowed us to delve deeper into understanding the mysteries of Mars.

The Mars Rover Missions

Since the early 2000s, NASA has been leading a series of Mars rover missions to gather data and explore the planet's surface. The rovers, designed to withstand the harsh Martian environment, have provided invaluable insights into the geological makeup, climate, and possible presence of water on Mars. To date, four rovers have successfully completed their missions: Sojourner, Spirit, Opportunity, and Curiosity.

Gathering Data: A Treasure Trove of Discoveries

Each Mars rover mission has brought forth a wealth of data that has expanded our understanding of the Red Planet. The rovers have collected samples, taken high-resolution images, measured atmospheric conditions, and analyzed the composition of Martian rocks and soil.

One of the most significant discoveries made by the rovers is evidence of liquid water in the past. The presence of hydrated minerals and geological formations, such as ancient riverbeds and sedimentary rock layers, strongly suggest that liquid water once flowed on the Martian surface. This revelation has profound implications for the possibility of past and even present life on Mars.

Searching for Life on Mars

The search for signs of life on Mars has been a driving force behind these missions. Scientists have been analyzing the collected samples for organic molecules and biosignatures—chemical signs of past or present life. While no conclusive evidence has been found yet, the presence of the building blocks of life, such as carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur, has been detected.

Moreover, ongoing research and analysis of Mars' atmosphere have revealed the existence of methane gas, which on Earth is often produced by living organisms. While the exact source of the methane on Mars is still uncertain, its presence further fuels the speculation of potential life forms beyond our planet.

Unveiling the Geological History

Mars is a treasure trove of geological wonders. The rovers' in-depth examination of the Martian terrain has unveiled a complex geological history. Evidence of ancient volcanoes, impact craters, and massive canyons indicates a turbulent past. These features provide a glimpse into the forces that have shaped the Martian landscape over billions of years.

Through the analysis of rock and soil samples, scientists have been able to determine the age of certain Martian geological formations, giving us insights into the planet's history. The data obtained from the missions has revealed that Mars was once a planet with a much thicker atmosphere, capable of supporting liquid water on its surface.

Paving the Way for Future Human Exploration

The findings from the Mars rover missions not only contribute to our scientific knowledge but also play a crucial role in preparing for future human missions to Mars. Learning about Mars' climate, resources, and potential hazards allows us to develop the necessary technology and strategies for long-duration space travel and colonization.

There is currently no conclusive evidence of extraterrestrial life, but many scientists believe it is likely that life exists elsewhere in the universe, given the vastness of the cosmos and the abundance of potentially habitable environments.

In the past, there have been a number of intriguing discoveries that have fueled speculation about the possibility of extraterrestrial life. For example, in 1977, the "Wow! signal" was detected by the Big Ear radio telescope at Ohio State University. The signal was a narrowband radio signal that lasted for 72 seconds and appeared to come from the direction of the constellation Sagittarius. The signal has never been detected again, and its origin remains a mystery.

Another intriguing discovery was the Martian meteorite ALH84001, which was discovered in Antarctica in 1984 and is thought to have originated on Mars. In 1996, scientists announced that they had found evidence of fossilized bacteria in the meteorite, although this claim remains controversial and is still debated by scientists.

There are several places in our solar system and beyond that are considered to be promising candidates for the search for extraterrestrial life. Here are a few examples:

1. Mars: Mars is the most similar planet to Earth in our solar system and has been the subject of intense study by scientists for decades. Evidence suggests that Mars may have had liquid water in the past, which is a key ingredient for life as we know it. Recent discoveries of methane and organic molecules on Mars have also raised the possibility of past or present microbial life on the planet.

2. Europa: Europa is one of the moons of Jupiter and is believed to have a subsurface ocean of liquid water, which is another key ingredient for life. It is thought that this ocean may be in contact with a rocky seafloor, providing a potential environment for microbial life.

3. Enceladus: Enceladus is a moon of Saturn that also has a subsurface ocean of liquid water. It is known to have geysers that shoot water vapor and icy particles into space, which could provide a way for scientists to sample the moon's interior and search for signs of life.

4. Exoplanets: In recent years, astronomers have discovered thousands of planets outside our solar system, some of which are located in the habitable zones of their stars -- the range of distances where liquid water could exist on a planet's surface. These exoplanets are potential targets for future missions to search for signs of life.

These are just a few examples of the promising places to search for extraterrestrial life, and scientists are continuing to explore and discover new candidates all the time.

Overall, while there is no definitive proof of extraterrestrial life, the possibility remains an active area of scientific research and speculation.
