We've discovered fiery, metal-melting planets, and icy worlds far from stars. Weird? It's our wheelhouse. Everything we've found makes us want to know more. go.nasa.gov/3dflOU5
We arrived, we sampled, and now we say goodbye. On May 10, #OSIRISREx will fire its main thrusters and start its long journey back to Earth with more than 60 grams of material from asteroid Bennu on-board. #ToBennuAndBack Join us live as we depart Bennu: go.nasa.gov/3eoxjtT
Excelsior! The #MarsHelicopter completed its 1st one-way trip and 5th flight on Mars. It touched down at its new location, kicking off a new demo phase where we test this new tech and see how it can aid future missions on Mars and other worlds. go.nasa.gov/ingenuity
🚁 #MarsHelicopter Update We're targeting as soon as Monday for the first controlled flight on Mars. Watch with the team as they receive data and find out if they were successful. Meet us in mission control April 19 at 6:15am ET (10:15am UTC): go.nasa.gov/32rmbG5
Last week @NASA announced nine scientists will join the Korea Pathfinder Lunar Orbiter (KPLO) mission. We are excited to confirm two scientists -- Dr. William Farrand and Dr. Gorden Videen -- are part of the Space Science Institute team! SSI press release: spacescience.org/docs/KPLO_PS_S…
❗UPDATE ❗Abstract submissions are now open until April 10. Please join us for May 17-21 for the "Applications of Statistical Methods and Machine Learning in the Space Sciences" conference! Please spread the news to anyone you think may be interested.

Today is the #SpringEquinox in the Northern Hemisphere! The twice-yearly equinoxes mark the points in Earth’s orbit when the Sun shines directly on the equator with nearly equal lengths of day and night. Read more: go.nasa.gov/30Yo7VH
What are you doing on #PiDay (Sunday, 3/14)? It’s a chance to enjoy some delicious pie, sure, but also a good time to learn how we use math @NASA to explore places like Jupiter with our #JunoMission. 🥧🚀 'Pi in the Sky': go.nasa.gov/3td2ahF More: go.nasa.gov/piday
A quick-look mosaic my team pulled together of the belly pan, now on the surface of Mars. Up next is to check my sampling system now that its cover panel is off. More images: go.nasa.gov/3rGQx2o
The moment that my team dreamed of for years, now a reality. Dare mighty things. #CountdownToMars
I love rocks. Look at these right next to my wheel. Are they volcanic or sedimentary? What story do they tell? Can’t wait to find out. #CountdownToMars mars.nasa.gov/mars2020
