Let's me be clear. This would end space science in the US. A 50% cut will scramble everything, and the chaos will result in a greater than 50% cut in science. If this happens, China will lap us in a couple of years. #planetsci #planetaryscience #astronomy www.planetary.org/press-r….

Graph of science funding of NASA from 1980 until present with the proposed 50% cut included. This cut would drop NASA Science to <$4B, which is approximately that in the early 1980s.

Just a little over one year ago, the Juno spacecraft made its first of two very close flybys of Jupiter's volcanic moon Io. This picture from JunoCam was processed to approximate true color. #planetaryscience flic.kr/p/2ppYk8v Credit: NASA / JPL-Caltech / SwRI / MSSS / Simeon Schmauß

Half lit image of the Jupiter moon Io showing a soft beige surface with greenish surfaces mixed in. Sharp mountains stand out against the otherwise smooth surface and cast long shadows near the terminator line. Black lava features are scattered around on the surface, one of them has a horseshoe shape.
The shadowed side of the moon is dimly lit by Jupiter and was slightly brightened during processing.

This video by @hankgreen.bsky.social covers why the Galilean moons are so amazing. I love Pluto too, but #Io, #Europa, #Ganymede and #Callisto are top tier Solar System objects. 🧪🔭 #Astronomy #Science #Geology #PlanetaryScience #Space Shoutout to the Europa Clipper: science.nasa.gov/mission/….

Have we been wrong about why #Mars is red⁉️ The Red Planet’s iconic colour has long been attributed to a dry rusty dust, but new research points to water-rich rust 👉 www.esa.int/Science_Expl... 🔭🧪 #planetaryscience #planetsci

The full disc of Mars is seen with the polar ice caps slightly off centre to the top left and bottom right. Clouds wrap around the planet’s curved horizons. Dark surface markings are clearly seen against the characteristic red tones of the dusty martian surface.

A meteorite that penetrated a Georgia home has been classified by UGA researchers as a 4.56-billion-year-old ordinary chondrite, predating Earth. Named the McDonough Meteorite, it offers insight into solar-system history. 🧪☄️🔭 #meteorite #planetaryscience #UGA #space news.uga.edu/uga-names-ne...

UGA analyzes and names new meteorite

The McDonough Meteorite crashed in Atlanta in June. Now UGA researchers are determining its origin and what group of asteroids it belongs to.

On Jan. 22, 2011, NASA's Lunar Reconnaissance Orbiter (LRO) took this image of the Moon from a distance of 39 km. The remarkable thing about it is that the Apollo 11 lunar module is in this frame. Can you find it? #planetaryScience #spaceExploration 🧪🔭🚀🛰️ Credit: NASA/GSFC/Arizona State University

We are just a year away from the start of the Trojan Flybys by the Lucy mission. 2027-2028 is going to be an exciting time for planetary science. I am really hoping for some surprises with these Trojan fly-bys. #planetaryscience 🧪 science.nasa.gov/blogs/lu….

NASA’s Lucy Begins Camera Tests Ahead of 2027 Trojan Flybys - NASA Science

Early observations of the Trojan asteroids will help scientists select the best camera settings for Lucy’s upcoming flybys, starting in 2027.

NASA folks in #planetaryscience - I'm trying to put together a network who can help our colleagues through RIFs on Tuesday. This is an EMERGENCY: Reports say that NASA probationary employees will be fired on Tuesday.

Philae was the 1st spacecraft to touchdown on a #comet OTD ten years ago. But because it bounced and thus landed somewhere unplanned, we did not know exactly where Philae was for another 2 years! Can you spot Philae in this image taken on Sept. 2, 2016 by the OSIRIS camera? #planetaryScience 🧪🔭🚀🛰️
