The four astronauts set to blast off Oct. 30 to the International Space Station visited Cape Canaveral over the weekend for a test run inside SpaceX’s new Crew Dragon Endurance spacecraft, one of the last training events before they return to Florida on launch week.

Commander Raja Chari, a U.S. Air Force colonel, leads NASA’s Crew-3 mission to the International Space Station. Chari and the mission’s other three astronauts visited Cape Canaveral Space Force Station Saturday for the Crew Equipment Interface Test, a customary pre-flight training event officials equate to a “test drive” or “walk through” of the spacecraft.

The four-person crew will launch on the third NASA crew rotation flight to the space station, and the fifth human flight on a Crew Dragon spacecraft overall, including a 2020 test flight and the all-civilian Inspiration4 mission last month.
