2 September 2022

Fresh off its success at the moon, India is now headed for the sun.

The nation launched its first-ever solar observatory today (Sept. 2), sending the Aditya-L1 probe skyward atop a Polar Satellite Launch Vehicle (PSLV) from Satish Dhawan Space Centre at 2:20 a.m. EDT (0620 GMT; 11:50 a.m. local India time).

The PSLV deployed Aditya-L1 into low Earth orbit (LEO) as planned about 63 minutes after liftoff, sparking applause and high fives in mission control.

"Congratulations, India, and congratulations, ISRO [the Indian Space Research Organisation]," Jitendra Singh, India's Minister of State for Science and Technology, said shortly after deployment on ISRO's launch webcast.

"While the whole world watched this with bated breath, it is indeed a sunshine moment for India," Singh added.

The successful launch followed on the heels of another big milestone for India: On August 23, its Chandrayaan-3 mission became the first to land softly near the moon's south pole.

Chandrayaan-3's lander-rover duo are expected to conk out in a week or so, when the harsh lunar night falls at their touchdown site. But Aditya-L1's long journey has just begun.

A long road to a good sun-viewing spot

Aditya-L1 won't stay in LEO forever:

After a series of checkouts, it will use its onboard propulsion system to head toward Earth-sun Lagrange Point 1 (L1), a gravitationally stable spot about 1 million miles (1.5 million kilometers) from our planet in the direction of the sun.

That destination explains the latter part of the mission's name. And the first part is simple enough: "Aditya" translates to "sun" in Sanskrit.

The 3,260-pound (1,480 kilograms) observatory will arrive at L1 about four months from now, if all goes according to plan.

But the long trek will be worth it, according to the ISRO.

"A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the sun without any occultation/eclipses," ISRO officials wrote in an Aditya-L1 mission description.

"This will provide a greater advantage of observing the solar activities and its effect on space weather in real time."

Indeed, another sun-studying spacecraft is already at L1 — the Solar and Heliospheric Observatory (SOHO), a joint NASA-European Space Agency mission that launched in December 1995.

(Several other spacecraft, including NASA's James Webb Space Telescope, are at Earth-sun Lagrange Point 2, which is a million miles from Earth, in the direction away from the sun.)

Solar flares, the coronal heating mystery and more

Once it's settled in at L1, the solar probe will use four three science instruments to study the particles and magnetic fields in its immediate surroundings and four others to scrutinize the sun's surface (known as the photosphere) and its atmosphere.

This work will help scientists better understand solar activity, including the dynamics of solar flares and coronal mass ejections (CMEs), ISRO officials say.

Flares are powerful flashes of high-energy radiation, and CMEs are huge eruptions of solar plasma.

Both types of outburst can affect us here on Earth. Intense CMEs that hit our planet, for example, trigger geomagnetic storms that can disrupt satellite navigation and power grids.

(As a side benefit, such storms also supercharge the gorgeous light shows known as auroras.)

Aditya-L1 will also tackle the "coronal heating problem," one of the biggest mysteries in heliophysics.

The corona — the sun's wispy outer atmosphere — is incredibly hot, reaching temperatures around 2 million degrees Fahrenheit (1.1 million degrees Celsius), according to NASA.

That's about 200 times hotter than the solar surface, which is "only" 10,000 degrees F (5,500 degrees C) or so.

It's still unclear what is responsible for this startling and counterintuitive discrepancy.

(Why would it be hotter away from the sun's core, where the energy-producing nuclear fusion reactions are occurring?)

Aditya-L1 has other science goals as well. For instance, the mission also aims to more fully flesh out the solar wind, the stream of charged particles flowing constantly from the sun, ISRO officials said.

Aditya-L1 will measure the composition of the solar wind and attempt to determine how it is accelerated.

And Aditya-L1 will do all this work on the cheap:

The mission's price tag is about 3.8 billion rupees, or $46 million US at current exchange rates.

That's in the same ballpark as Chandrayaan-3

India's first successful moon-landing mission costs about 6.15 billion rupees, or $74 million US.

For comparison, NASA's most recent big-ticket sun mission, the record-setting Parker Solar Probe, costs roughly $1.5 billion.

This disparity should not be viewed as an indictment of NASA, however; labor costs are much higher in the United States than in India, among other differences between the two nations' economies.

Aditya-L1 is a coronagraphy spacecraft to study the solar atmosphere, designed and developed by the Indian Space Research Organisation (ISRO) and various other Indian research institutes.

India launched its first space mission to study the sun on Saturday, less than two weeks after a successful uncrewed landing near the south polar region of the moon. The Aditya-L1 spacecraft took off on board a satellite launch vehicle from the Sriharikota space center in southern India on a quest to study the sun from a point about 1.5 million kilometers (930,000 miles) from earth, known as L-1. The spacecraft is equipped with seven payloads to study the sun's corona, chromosphere, photosphere and solar wind, the Indian Space Research Organization said. After over an hour, the ISRO said the launch was "accomplished successfully."

India and space #1

This week with the launch of Chandrayaan-3 India has become the 4th nation to land on moon, first to even set foot on the southern part of the moon. PM Modi said, with this India has leaped a big step in space and technology. Chandrayaan-3 is a Lander-Rover mission, it is a geosynchronous satellite made by ISRO, It was launched in three stages and loaded with many equipments (ILSA-to measure seismic activity, ChaSTE-to measure moon’s surface temperature, LP- Langmuir Probe to measure near-surface plasma density over time) which is said to help ISRO researchers collect more data of moon and to get its better understanding of it.

Chandrayaan-3 was launched on 14th July 2023 from Satish Dhawan Space Center, it landed on moon after 40-day voyage at 6:04 pm. With its successful mission on moon PM Modi announced that India will be expanding its satellite network, will send humans into space, will develop semi-cryogenic engine, plan on development and making of space station, send an observatory-class satellite to study solar activities (Aditya-L1, launched on 3rd September) and so on.

India on 3rd August 2023 passed Indian space Policy 2023, where space budget is increased from 2% to 10%. The policy roles of different space agencies like space sector PSU NewSpace India Limited (NSIL), the Indian National Space Promotion and Authorization Center (IN-SPACe), and ISRO are more precisely defined. The ISRO chairman said this policy explains very well the framework for the private sector to use facilities of ISRO and also encourages investors to put money in the field.

India had its setbacks with Chandrayaan-2 and 1, but ISRO doesn’t seem to lose its determination on the way and doesn't seem on giving up anytime soon. Even though ISRO is late in the race to explore space, but it looks like it will cover the gap soon.

ISRO prepares for critical maneuver as Aditya L1 is set to reach its destination on January 6

The Indian Space Research Organisation (ISRO) stands at the edge of groundbreaking achievement with its first solar mission, Aditya-L1. 

The chairman of ISRO, S Somnath has disclosed that the spacecraft is set to arrive at its designated destination, the L1 point, on January 6, 2024, after covering a distance of 1.5 million kilometers through space. He stated that the insertion of Aditya-L1 into the L1 point is slated for January 6, 2024, but the specific time is yet to be determined.

L1, also known as Lagrange Point 1, holds a strategic position in space where the gravitational forces of the Earth and the Sun balance out each other, enabling a spacecraft to sustain a stable position relative to both celestial bodies. This exceptional vantage point offers an uninterrupted view of the Sun, turning it into an ideal location for solar observations.

The inception of the Aditya-L1 mission dates back to January 2008, originating from the Advisory Committee for Space Sciences (ADCOS). Initially conceived as a modest 400 kg satellite orbiting 800 km above Earth, the mission expanded its scope to encompass an extensive study of the Sun’s corona from a distance of 1.5 million km away from our planet.

ISRO announced the successful launch of the ASPEX experiment and revealed plans to study solar wind using Aditya-L1 The Indian space agency ISRO (Indian Space Research Organization) announced that the Aditya Solar Wind Particle Experiment (ASPEX) payload on board the Indian Aditya-L1 satellite has begun to function normally. Aditya-L1 was launched on a PSLV-C57 launch vehicle from Sriharikota on September 2. The satellite is placed in a halo orbit at the L1 Lagrange point, located between the Earth and the Sun. The goal of the Aditya-L1 project is to study solar wind and space weather. The information obtained by the satellite will reveal the origin, acceleration and direction of the solar wind, as well as understand its impact on Earth. [caption id="attachment_85365" align="aligncenter" width="780"] Aditya-L1 mission[/caption] Aditya-L1 mission: instruments begin collecting data on space weather and solar wind Aditya-L1 is the second ISRO spacecraft to move beyond the Earth's gravitational sphere of influence after the successful Mars Exploration Mission. Aditya-L1 carries seven scientific instruments, including four solar observation instruments and three plasma and magnetic field measurements. ASPEX includes two important instruments: the Solar Wind Ion Spectrometer (SWIS) and the High Energy Particle Spectrometer (STEPS). STEPS was launched on September 10th and SWIS started on November 2nd this year and has already shown results. SWIS, using two sensor units with a full 360° view, operates in planes perpendicular to each other. This spectrometer monitors solar wind ions, particularly protons and alpha particles. According to ISRO, SWIS has successfully measured these particles, which are a major contributor to the solar wind. An energy histogram obtained from one of the SWIS sensors over two days in November shows changes in the number of protons (H+) and alpha particles (He2+). These data provide a rich set of information about the behavior of the solar wind. This measurement will help resolve questions about the properties of the solar wind, its basic processes and influence on the Earth. Also, the change in the proportion of protons and alpha particles observed by SWIS has the potential to provide indirect information about the occurrence of coronal mass ejections at the L1 Lagrange point. After careful analysis of the collected data, the scientific community expects to gain new knowledge about the characteristics of the solar wind and its impact on Earth from the ASPEX experiment on the Aditya-L1 satellite.
