Woooooo! Amazing news and work from @whimsicallambda.bsky.social
Well done and can’t wait to listen to more episodes! 🚀 ✨ 🔭
2/2 This🏆is a nod to the importance of discussing career paths, Scientific methods, & the social impacts of 🧪.
I’m looking for more researchers to share their journeys and scientific papers. If you have a story to tell, my DMs are open! Let’s keep building this community.

The leadership of the American Astronomical Society explains why "move all the telescopes to space" is neither possible nor desirable: spacenews.com/the-future-o...
I would only add that there are individual telescopes that mass more than everything ever launched into space put together.
Apply to join the summer 2026 NASA EarthRISE Developers Academy! Use NASA Earth observations to address real-world challenges. Sites in Virginia, Colorado, and Alabama. Virtual opportunities too. Due Friday, March 6. appliedsciences.nasa.gov/what-we-do/c... #nature #coding #data #agriculture #water

A white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white.
Our first glimpse of comet 3I/ATLAS from Juice's science camera 😍☄️
The precious data from the mission's November observations of the interstellar comet arrived on Earth last week. Teams are now digging in to discover what they reveal.
Stay tuned for updates!

What does that mean for planetary evolution?
For habitability?
For how weird our own Solar System might be?

This is so friggen neat.
First "GPS" on another planet, maybe?!
The Perseverance rover on Mars can now know where it is to within 25cm, using a technique that snaps panoramic images, flattens them into a bird's-eye view, then compares them with orbital images.
Clever!

Death Gulch at Yellowstone is "a natural death trap for animals" due to CO2 and H2S accumulation. "At high concentrations..., these gases are lethal, and the death of one animal is thought to lure in others, who are then also overcome." Also, Wahb Springs.

Blueprint for the Space Rider, explaining all its parts and the size of each part.
Space Rider might be small compared to Vega-C or the huge Ariane 6 rockets, but it's all a matter of perspective 💁🏻♀️
This Space Rider blueprint poster shows its dimensions and components compared to a 1.74 m human.
The Reentry Model has a cargo-bay for payloads, able to land on ground and fly again.
If you liked this experiment, I published a full piece today in the same vein: a text that gets 100 years older with every section, from a modern blog post to a medieval chronicle.
It's a single story spanning 1000 years of English. See how far you get.

Thanks to @iansample.bsky.social at the Guardian for covering the devastating funding cuts that are being proposed for UK (astro)physics, and the dire impact these would have on young researchers. Will UKRI/STFC reconsider? Will the UKGov step in?🤞👩🔬🧪⚛️🔭

This is true, but it’s also true that NASA since Apollo has delivered two Voyagers, five Mars rovers, the Hubble Space Telescope, a fleet of Earth-observing satellites, near-earth asteroid detection, and continuously inhabited the International Space Station for 25 years. Among other things.

New paper on the pollution of the upper atmosphere through de-orbiting satellites and space debris (in this case a Falcon 9 upper stage).
"This new type of pollution has unknown consequences for the upper atmosphere and ozone layer."
This paper is now available in final journal format, including the authors' one-page summary for the print magazine.

The FCC just opened public comments on SpaceX's plan to launch a million satellites to do AI compute in space. Under the current proposal, an environmental review won't be required. Please consider submitting a public comment to oppose this damaging plan.

NASA to Rollback Artemis II Rocket, Spacecraft
www.nasa.gov/blogs/missio...
Himmelskibet (A Trip to Mars), considered to be the first feature-length space film, was released 108 years ago today.
"Inspired by Napoleon, the navy officer Avanti Planetaros endeavours to chart the cosmos and explore its strange planets."
Glory to those who came before. 🖖
Watch it:
Potential Artemis II launch dates in April include April 1, 3, 4, 5, 6, and 30.
NASA Administrator Jared Isaacman says rollback to Vehicle Assembly Building to repair helium flow problem on Artemis II rocket will take March launch window for Moon mission out of consideration. Here are the potential launch dates in April.
