This image is a snapshot of a panoramic photo captured by the Mars Science Laboratory Curiosity Rover within Gale crater, Mars. In the foreground dark rocky hills are seen sloping down from left to right. Beyond those hills is the crater floor, with is dotted with occasional smaller hills and craters. In the distance the steep crater walls stretch across the image.

Strongly recommend going to photojournal.jpl.nasa.gov/catalog/PIA2..., opening the Full-Res JPEG in your browser, zooming in, and spending a mindful martian minute scrolling across Gale crater #Mars #CuriosityRover #NASA #JPL

YouTube video by NASA Video Details of New Perseverance Mars Rover Finding

For those who wish to listen to the 10 September #NASA Mars 2020 Rover Perseverance announcement, here's the #YouTube Link www.youtube.com/watch?v=-StZ...

A deep image of interstellar Comet 3I/ATLAS captured by the Gemini Multi-Object Spectrograph (GMOS) on Gemini South at Cerro Pachón in Chile, one half of the International Gemini Observatory, partly funded by the U.S. National Science Foundation (NSF) and operated by NSF NOIRLab. The image shows the comet’s broad coma — a cloud of gas and dust that forms around the comet’s icy nucleus as it gets closer to the Sun — and a tail spanning about 1/120th of a degree in the sky (where one degree is about the width of a pinky finger on an outstretched arm) and pointing away from the Sun. 3I/ATLAS is only the third confirmed interstellar visitor to our Solar System. The exposures tracked the comet as it traveled across the sky, and the final image is composed to freeze the stars in place during the observation. Two small colored trails from unrelated asteroids with a different motion from that of the comet can also be seen. These observations of Comet 3I/ATLAS were conducted during a Shadow the Scientists program hosted by NSF NOIRLab.

This new #JWST of stars being born just dropped, and it is GORGEOUS

Just reupping this.

Idk if we are way behind on positions compared to normal because of *waves hands at everything* or bc I’m not on twitter anymore. I’ve shared it all the same places I normally do.

A black and white mosaic of images from Mars. A distant hazy horizon is punctuated by a white mount and various layered hills and butted. At the bottom is the rear of the Curiosity Mars rover - a gray cylindrical antenna is next to a white finned RTG.

The engineering side of our mission rarely gets told....but we're pushing to turn every heckin' joule of that RTG into pure distilled awesomeness. Thanks to @abbyfrae.bsky.social for the postcard idea. I had a LOT of fun sequencing and then processing it :) www.jpl.nasa.gov/news/marking...

Need me to drop off a care package?

NASA Releases its Spinoff 2025 Publication This publication features commercial infusions of NASA technologies, including research originated at NASA Glenn.

NASA has published this year’s edition of Spinoff, their annual magazine showcasing all the ways NASA technology has been reused for new things. Refer to this next time someone questions if it’s worth spending money on space research 🔭🧪 www.nasa.gov/newsletters/...

I really hope after tonight that more Americans will appreciate, understand, and value the significant and lifesaving work done by the National Weather Service, and NOAA in general.

Happy birthday!

This is what makes NASA strong - the best and brightest!

Working at NASA is a dream for many around the country and even the world. Positions don't just get created. They are extremely rare and highly competitive. The folks that get them are _the_ best at what they do. What do they do? 1/6
