The Crew-4 astronauts are getting ready for their mission to the International Space Station.
The crew of the Crew Dragon will launch on a Falcon 9 rocket from the Kennedy Space Center in Florida on Friday, April 15.
The Crew-4 mission will be the first time that Hines and Watkins have been to space.
The crew has been training at both the Kennedy Space Center and the headquarters of the company.
Crew Dragon has a simulation that features flight- realistic hardware, displays, and seats.
Crew Dragon training includes getting familiar with routine tasks but also learning how to deal with unexpected situations such as system failures.
Commander Lindgren and pilot Hines took their places in the center seats, with access to flight displays they can use to monitor the spacecraft's status and, if needed, take manual control.
The crewmates have taken a trip on the Dragon recovery vessel, which will be used to collect the astronauts after the splashdown. The astronauts were given a tour of the hangar where the Falcon 9 rockets are refurbished and ready for flight.
The Crew-4 mission will take place 20 months after the first crewed flight of the Crew Dragon spaceship.
The Crew-1 astronauts were sent to the International Space Station for a six-month stay in November 2020.
