What’s new with the crew?🧑‍🚀 The @NASAArtemis II crew has hit the ground running with training at Johnson Space Center as they prepare to travel to lunar orbit. Soon, the four crew members will embark on a journey that will be the blueprint to take us further than ever before.

And we’re rolling! Our water-hunting VIPER Moon rover will use two folding ramps to descend from lander to lunar surface. A test robot and model lander gave the ramp design a try at @NASA_Johnson to make sure it will all roll smoothly on the Moon 🌔: go.nasa.gov/3ctZpmu

#AlphaTrainingRecap: We spent a lot of our training time on spacewalks as these are complicated, important and require lots of preparation. From spacesuit fit checks to procedures and test runs in simulated weightlessness: pool time! flic.kr/p/2jKBV7X
