YIPPEEE! Got a ROSES proposal funded as PI! Some exciting stuff ahead working with @NASA OTPS office. More details later! 🌙 So excited for our team!!!

Far beyond Pluto, trillions of cold comets circle the sun in a lazy swarm called the Oort Cloud. A new simulation indicates what this comet-cloud looks like: a loose spiral that resembles a miniature galaxy. arxiv.org/abs/2502.11252

The Artemis II crew has recently been immersed in flight operations reviews and simulating @NASA_Orion’s return to Earth. The crew wants to extend a special thank you to all the different teams across the country that are coming together to build the @NASA_SLS rocket.

The crew of Apollo 14 found it difficult to sleep - partly due to the angle at which they landed. They felt they were slipping down into a crater, and Ed Mitchell would regularly lift the blinds to check they were not. Wonderful clarity in this small section of the full panorama.

Ghost riders in the sky. @fireflyspace’s Blue Ghost lander recently completed a maneuver to adjust its orbit around the Moon. We are on track for a landing on March 2.

Your package is scheduled for delivery 📦 @fireflyspace’s Blue Ghost lunar lander is set to land on the near side of the Moon on March 2 at 3:45am ET (0845 UTC) with NASA science and tech aboard. Watch the landing live with us! go.nasa.gov/4gKmzTJ

Red carpet ready! 📸 #EEBAFTAs

Ever noticed how the Moon seems HUGE when it’s near the horizon but smaller when it’s overhead? Trick of the eye or something more? Scientists have debated this for 2,000+ years, and we still don’t have a definitive answer! Find out what we do know: go.nasa.gov/42UHQqw

European member of the Astronaut Reserve, John McFall and the team at @ESA have shown it is possible for someone with a physical disability to live and work on the @Space_Station. 🛰️ Read more about the Fly! Mission Ready phase 👉 esa.int/Science_Explor… Hear from John 👇

Development and Evolution of Icy Layer Outcrops on Mars' North Polar Ice Cap: Observations of Vertical and Lateral Variability. buff.ly/4k0Ut9Q Study finds lateral variability on the meter-scale in the protrusion of individual marker beds that reflect local conditions.

Encyclopædia Britannica will continue to use ‘Gulf of Mexico’ for a few reasons: -We serve an international audience, a majority of which is outside the U.S. -The Gulf of Mexico is an international body of water, and the U.S.’s authority to rename it is ambiguous. 🧵⬇️

Howard is officially reclassified as an R1!!!!!

Life as we know it needs water to survive, so as we search for life outside our solar system, astrobiologists are often guided by the phrase “follow the water.” Learn how the SPHEREx mission will help in that quest across our Milky Way galaxy: go.nasa.gov/4hUzm76

Aqueous Alteration as an Origin of Martian Magnetization. buff.ly/4k96Osy Study finds that aqueous alteration of dunites at low water-to-rock ratios can generate sufficient magnetite to account for the strongest magnetic anomalies.
