Astronauts dive into Mk-2 Training

Recent aerospace news hasn’t been the happiest, but there was one moment of watery goodness I’d like to share. 

On June 10, Blue Origin shared a video taken at the Johnson Space Center’s Neutral Buoyancy Tank that shows astronauts climbing around in and on a simple mockup of their Mark 2 lander, which should be transporting astronauts to and from the Moon’s surface in coming years. 

Currently, NASA plans not to use the Mark 2 until Artemis V, but it is possible its use could be moved forward if Blue Origin leapfrogs SpaceX in their lander developer. Blue Origin currently plans to launch their smaller, Mark 1 cargo lander on their next New Glenn launch, which is slated for no earlier than August 15 of this year. We’re going to be watching this development closely and look forward to bringing you updates as we get them.
