Today, the SpaceX Crew Dragon Endeavour flawlessly brought the two astronauts Robert “Bob” Behnken and Douglas “Doug” Hurley safely back home to Earth. In a remarkable series of maneuvers, the craft autonomously positioned itself for the correct orbit for splashdown. This was the first American splashdown in nearly 50 years!
NASA Administrator Jim Bridenstine wrote on his blog: “We need to remember that this is just the beginning. Now is the time to capitalize on all the great programs that have recently been established, to include going sustainably to the Moon under a program we call Artemis. We’re going to the Moon sustainably; we’re going to go with commercial partners, with international partners. We’re going to use the resources of the Moon to learn how to live and work on another world for long periods of time. We’re going to take all of that knowledge and we’re going to go to Mars.”
As Dragon prepared to re-enter Earth’s orbit, it first executed the separation of the claw and trunk (on the lower portion of the craft), which were jettisoned away from the spacecraft. Thrusters at the forward point of the craft to decelerate it, burned for 11 minutes, the longest burn ever.
When completed, the cap for the capsule closed back over the thrusters, and began to maneuver about 90 degrees, such that the broadest portion of the capsule would shield the crew from the 3500 F degree heat, generated by the speed and friction with Earth’s atmosphere.
During this time, there was an expected six-minute blackout, due to the plasma generated by the heat of the descent on the outside of the spacecraft.
