With the construction of Harmony and Unity Space Station, KSEA decides it’s a good time for the Aurora Missions to be re-tooled.  Since the stations both have their own dedicated lander, the lander payload will be replaced with an Explorer-2 style Habitat module to make space travel a more comfortable experience!

This will also deal with the tight life support budgets that have plagued some recent missions.

Since Crew Vehicle/Habitat Modules appears to be the new direction for crewed space flight, this will also be a great test of equipment for upcoming missions!  As for refueling the stations, that will be done with an automated refueling vehicle!
