@astro_Pettit One my all time favorites of your videos / experiments

@ForrestMeyen @LunarOutpostInc Congrats Forrest! 🏎️

@willmenaker Playoffs got everybody pulling up from half court

We are still doing extraordinary things

POV: You’re coming home after a journey around the Moon. 🌕

Before reentering Earth’s atmosphere at the end of Artemis II, the Orion spacecraft’s crew module — carrying the astronauts — separated from the service module that provided propulsion and power throughout the mission.

Jaw-dropping 3D visualization of all known exoplanets in our cosmic neighborhood! Thinking about all the moons of those planets…

@drcrater We want to pick your brain about the pumice-y shocked Coconino! We found some near on the proximal ejecta blanket near the S. Rim / small open pit silica mining operation. Enjoy!

[NASA Mars @NASAMars]

Got something weighing you down? Shake it off (like Curiosity)!

The Martian explorer unintentionally picked up a rock while drilling a recent sample, but the team was able to dislodge it by having the rover move its robotic arm and vibrate the drill until the rock fell off.

@NDR_lufc Heard Rome was sacked

@conspiracyslyr Those are hot pixels on the moon silhouette?

@MattJFootball @TheBlueRoomEFC @LondonMarathon Insane time

Only one chance in this lifetime…

Like watching sunset at the beach from the most foreign seat in the cosmos, I couldn’t resist a cell phone video of Earthset. You can hear the shutter on the Nikon as @Astro_Christina is hammering away on 3-shot brackets and capturing those exceptional Earthset photos through the 400mm lens. @AstroVicGlover was in window 3 watching with @Astro_Jeremy next to him.

I could barely see the Moon through the docking hatch window but the iPhone was the perfect size to catch the view…this is uncropped, uncut with 8x zoom which is quite comparable to the view of the human eye. Enjoy.

@AeroBigMike Been having these feelings since launch

[Jeremy R. Hansen @Astro_Jeremy]

Ces derniers jours, mes coéquipiers d’Artemis II et moi avons effectué des simulations afin de déterminer comment optimiser chaque pas à la surface lunaire lors de futures missions. Nous enfilons nos combinaisons pour ces tests exigeants, alors que nos corps s’adaptent encore à la suite de notre voyage autour de la Lune.

[Lee Saper @lsaper]

An extraordinary team that absolutely smashed it yesterday!

[NASA Science @NASAScience_]

Behind every lunar view is pure Moon (science) joy.

[Lee Saper @lsaper]

@JPMajor Trio of planets visible as well, I think

[Lee Saper @lsaper]

Artemis II flyby and a SoCal jellyfish to top it all off. What an incredible day.

@Dmanphotos @MaxQApp There will be a total solar eclipse, it’s going to be amazing

POV: You're flying by the Moon.

This visualization is designed to show you what exactly the Artemis II astronauts will see outside their window during their lunar flyby.
