Great week-end for small bodies ! Hayabusa 2# flyby of asteroid Torifune (www.jaxa.jp/press/2026/0...) and Tianwen-2 images of asteroid Kamo'oalewa (www.xinhuanet.com/20260706/eb8...) ! #PlanetaryScience

I'll be at #Exoplanets6 next week with a poster on MiTHOS, our Astrophysics SMEX mission concept out of @jhuapl.bsky.social MiTHOS studies the climates of hot Jupiters with a large population study of spectroscopic phase curves 🌈 Come find me to grab a sticker and learn about MiTHOS! 💫 🪐🔭🧪

The Artemis II crew just gave us an 80's sitcom intro and it's absolutely hilarious! Freeze frames, cheesy grins, theme song energy. These are the four humans who are about to around the Moon. NASA said fun and we are here for it!

The Lunar flyby happens today. Follow @barbylon.bsky.social for an insider view from the #ArtemisII Lunar Science Team! 🧪🔭🌘🚀

The #ArtemisII Lunar Science team spent yesterday refining our targets into a time-correlated targeting plan for the actual Moon we will see. 🧵 🧪🔭🌘🚀

The Integrity spacecraft just entered the lunar gravitational sphere of influence, at 0438 UTC Apr 6. Wiseman, Glover, Koch and Hansen are now the 25th to 28th humans to have left terrestrial space.

Yes, I already shared this. Yes, I am unashamedly sharing it again. This image means so much to me personally as a #WomenInSTEM and space scientist 🔭🧪 🌗🪐🌎. Christina Koch once worked at GSFC, where I now work, and was at APL, where I worked before, when selected as an Astronaut!

NASA just dropped this image of Artemis II astronaut Christina Koch looking back at us. The first woman to ever see our planet in its entirety. I’m not crying you’re crying 🥹🔭🧪 📸: NASA

Awesome view of @NASAArtemis II, as viewed from NOAA weather satellite. Note the dark (warmer) dot launching off from Cape Canaveral and off to the northeast! #flwx #artemis

Oh, I was definitely crying! #NASAProud #ArtemisII 🌗👩🏻‍🚀🚀🧪🔭

Incredibly moved by the Artemis II launch. (I might be crying. Not saying I am, but I might be.) We can still do amazing and good things.

Mindful breathing time 🧘‍♀️ #ArtemisII 🌕🌘🌗🚀👩‍🚀

If you wanna watch a really big rocket roll very slowly out to the launch pad in Florida, live, go here now m.youtube.com/watch?v=nrVn... It’s the Artemis II mission, aiming to launch in the coming weeks to send humans to the Moon for the first time in over half a century 🧪

Hooray for #Pandora!! This is a mission led by Elisa Quintana of #NASA-GSFC, one of the most brilliant scientific leaders I know. This small satellite will study nearby #exoplanets at a level of detail we can't do with #JWST because of the high demands for time on JWST.🪐🔭🧪

#NOAA funding is valuable because it predicts #SpaceWeather events that could threaten satellites and power grids. 🧪🪐🔭

Steve Herman@newsguy.bsky.social · last yr.

NOAA issues a prediction for a severe geomagnetic storm for Monday that could result in aurora being seen as low as Alabama and northern California.

#NASA and #NSF fund research into multiple aspects of these types of events, including lifesaving work that predicts their occurrence 🧪🔭🪐

Jamie Shulmeister@jamie-shulmeister.bsky.social · last yr.

This footage of a rock and ice #landslide from the Birch Glacier in Switzerland is spectacular. There seems to be a lake forming behind the landslide fill in the valley floor, so the sequence of events may not be over. #Geomorphology is exciting. #geology #geography ⚒️ #geoscience

Did you know that #NASA has a program called #PlanetaryProtection? This program not only protects Earth from #asteroid and #comet impacts but also helps us to understand how the solar system formed based on where all these small bodies ended up 🧪🪐🔭
