This year, the Sierra Space Dream Chaser spaceplane is to make its way to the International Space Station.
A multiple-hour simulation on December 5 matched up both Sierra Space and NASA Johnson Space Center controllers to ring out procedures, even simulating a number of flight controller problems.
In addition to thousands of hours of cumulative classroom and self-study training across the team, simulations provide “a unique laboratory” for bringing everything together to demonstrate the Sierra Space team’s knowledge, as well as test flight controller skills.
