“The world is little, people are little, human life is little. There is only one big thing — desire.”

college is like. i am the stupidest person in the world. i am a god. i am universally loved. these people only tolerate me because they live with me. everyone in this library desires me carnally. i am repulsive. i am myself. i am as far from myself as i have ever been. i am an adult and i have never left the womb.

- my new @mujiuk planner!

.

got home from classes at about 5pm, made dinner and started on research for my essay for one of my modules! going really well so far!

i'm sooo happy that i bought the muji planner for 2022! i had one in 2020 but didn't get one for 2021 and i've really missed the layout of the muji planner✨

just some reflections: i've been finding that it feel like time is passing by so fast but i have so many things i wanna do! i think having a planner and using it to organize my day is my way of enacting control over my life in a period of time where it seems like everything's going by so fast??

09.26.21 -- this week was crazy. my school had a norovirus outbreak, i had my multivariable calc midterm, and i finished my first 11+ mile run!

11.12.21 | woke up early this morning to go to the science library to rewrite some notes for orgo before class later this afternoon. I have thoroughly been enjoying coming to the library in the early mornings to get work done. There’s just something about knowing that I get to start my day before the morning rush occurs that gets me motivated to study. What motivates you?

some dark style studies today, in homage for the cloudy climate ⛅️

it feels so good to be back to posting! my day went by in sorting out the notes of last year and finishing off some CS assignments it was quite productive I managed to watch 2 physics lects also! here's this month's bujo I really loved the calm vibe these colours give, brown is becoming my fav colour if you can't tell already. I hope we all have a lovely week♡︎

Lasers Bring Internet Speeds to Space

Pew. Pew. Lasers in space!

Iconic movie franchises like Star Wars and Star Trek feature futuristic laser technologies, but space lasers aren’t limited to the realm of science fiction. In fact, laser communications technologies are changing the way missions transmit their data. The Laser Communications Relay Demonstration (LCRD) blasts into space this weekend, demonstrating the unique – and totally awesome – capabilities of laser communications systems.

Currently, NASA missions rely on radio frequency to send data to Earth. While radio has served the agency well since the earliest days of spaceflight, there are significant benefits to laser systems. Just as the internet has gone from dial-up to high-speed connections, lasers communications’ higher frequency allows missions to send much more information per second than radio systems. With laser communications, it would only take nine days to transmit a complete map of Mars back to Earth, compared to nine weeks with radio frequency systems.

LCRD will demonstrate these enhanced capabilities from 22,000 miles above Earth’s surface. And although the mission uses lasers, these lasers are not visible to the human eye. Once in orbit, the mission will perform experiments using two telescopes on Earth that will relay data through the spacecraft from one site to the other over an optical communications link. These experiments will help NASA and the aerospace community understand the operational challenges of using lasers to communicate to and from space.

On Earth, there are ground stations telescopes that will capture LCRD’s laser signal and send the data to the mission operations center in New Mexico. The two ground stations are located on Haleakalā, Hawaii and Table Mountain, California. These picturesque locations weren’t chosen because they’re beautiful, but rather for their mostly clear skies. Clouds – and other atmospheric disturbances – can disrupt laser signals. However, when those locations do get cloudy, we’ve developed corrective technologies to ensure we receive and successfully decode signals from LCRD.

This demonstration will help NASA, researchers, and space companies learn more about potential future applications for laser communications technologies. In the next few years, NASA will launch additional laser missions to the Moon on Artemis II and to the asteroid belt, even deeper into space. These missions will give us insight on the use of laser communications further in space than ever before.

Ultimately, laser systems will allow us to glean more information from space. This means more galaxy pics, videos of deep space phenomena, and live, 4K videos from astronauts living and working in space.

Laser communications = more data in less time = more discoveries.

If laser communications interests you, check out our Space Communications and Navigation (SCaN) Internship Project. This program provides high school, undergrad, graduate, and even Ph.D. candidates with internship opportunities in space communications areas – like laser comm.
