This afternoon, NASA astronauts Bob Behnken and Doug Hurley are scheduled to begin their journey again to Earth inside SpaceX’s new Crew Dragon, bringing an finish to their historic flight to the Worldwide Area Station. If all goes to plan, the 2 will splash down within the Crew Dragon off the western coast of Florida on Sunday afternoon.

Getting again to Earth from orbit isn’t any straightforward activity, and the 2 astronauts have an extended journey forward of them earlier than they’re again on stable floor. As soon as Behnken and Hurley undock from the house station, they’ll spend the subsequent 18 hours in orbit, slowly distancing themselves from the ISS, earlier than making the dive into Earth’s ambiance. That begins a harrowing journey all the way down to the floor, because the Crew Dragon experiences excessive temperatures reaching as much as 3,500 levels Fahrenheit and slows down from 17,500 miles per hour.

Issues get underway this afternoon, when Behnken and Hurley climb contained in the Crew Dragon and shut the hatch at round 5:45PM ET. They’ll stay inside till the scheduled time for undocking at 7:34PM ET. Hooks holding the Crew Dragon in place on the Station will retract, releasing the capsule into house. Proper after that, thrusters on the Crew Dragon will do two fast burns as a way to separate out farther from the ISS.

A pair hours after undocking, the Crew Dragon will do one other engine burn to place the car on the trail towards its deliberate touchdown web site. Proper now, NASA and SpaceX are concentrating on a splashdown off the coast of Pensacola, on the sting of Florida’s panhandle within the Gulf of Mexico. The placement is one among seven potential websites round Florida the place the Crew Dragon might land. NASA and SpaceX would reasonably the Crew Dragon land on the east aspect of Florida, close to Kennedy Area Middle in Cape Canaveral, Florida. Nevertheless, Tropical Storm Isaias is projected to skim jap Florida this weekend, forcing Behnken and Hurley to go farther west. If Pensacola doesn’t work out, the Crew Dragon will head towards a backup web site outdoors of Panama Metropolis. If both location works out, this would be the first time a spacecraft has touched down within the Gulf of Mexico.

After that last burn, it’s an extended wait till issues decide again up once more. Behnken and Hurley will attempt to get some sleep in a single day forward of their scheduled descent by means of the ambiance on Sunday afternoon. At round 1:44PM ET on Sunday, SpaceX will jettison an enormous chunk of the Crew Dragon forward of the touchdown: the capsule’s trunk. It’s a cylindrical piece of {hardware} hooked up to the again finish of the capsule, offering help throughout launch and offering additional room to hold cargo. It additionally homes all the photo voltaic panels that generate energy for the Crew Dragon throughout flight. However when it comes time to land, SpaceX doesn’t want the trunk anymore, so it separates and falls into Earth’s ambiance, the place it burns up.

At 1:49PM ET on Sunday, the ultimate descent begins. The Crew Dragon will burn its thrusters once more, taking the capsule out of orbit and setting it on track for Earth. That begins a really fast sequence of occasions. The Crew Dragon will begin to warmth up because it falls by means of the ambiance, whereas the capsule’s outer warmth defend ought to shield the car and the crew inside. The quantity of heated plasma that builds up across the capsule is so intense that it truly triggers a communications blackout that may last as long as six minutes.

The ambiance helps to cushion the Crew Dragon’s fall, slowing it down immensely. However the capsule wants a little bit additional assist to get down safely. At an altitude of roughly 18,000 ft, two drogue parachutes will deploy from the capsule when it’s shifting at round 350 miles per hour. These small chutes gradual the capsule all the way down to about 119 miles per hour forward of the primary parachutes deploying. When the Crew Dragon reaches an altitude of 6,000 ft, 4 large crimson and white parachutes will deploy to maintain braking the car, permitting it to the touch down gently within the ocean at round 2:41PM ET.

As quickly because the capsule is within the water, two SpaceX boats carrying dozens of individuals will meet up with the Crew Dragon. They’ll hoist the capsule out of the ocean, retrieve the parachutes, after which get Behnken and Hurley out into the contemporary air. The astronauts will then be airlifted to shore, due to a helipad on one of many restoration vessels. The helicopter will take them to a aircraft that may transport them again to Houston.

NASA’s protection of the touchdown will start at 5:15PM ET, simply earlier than Behnken and Hurley get contained in the Crew Dragon. The company will present steady reside protection throughout the splashdown, displaying scenes from mission management facilities at each NASA and SpaceX. That manner, viewers can comply with together with each a part of Behnken and Hurley’s journey house.
