How to watch two NASA astronauts journey home in SpaceX’s Crew Dragon capsule

This afternoon, NASA astronauts Bob Behnken and Doug Hurley are scheduled to start out 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 strong floor. As soon as Behnken and Hurley undock from the house station, they’ll spend the following 18 hours in orbit, slowly distancing themselves from the ISS, earlier than making the dive into Earth’s environment. 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 to be able 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 situation is considered one of seven potential websites round Florida the place the Crew Dragon might land. NASA and SpaceX would somewhat the Crew Dragon land on the east facet of Florida, close to Kennedy Area Middle in Cape Canaveral, Florida. Nonetheless, Tropical Storm Isaias is projected to skim jap Florida this weekend, forcing Behnken and Hurley to move 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 ultimate 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 the environment 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} connected to the again finish of the capsule, offering assist throughout launch and offering additional room to hold cargo. It additionally homes the entire 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 environment, 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 the right track for Earth. That begins a really fast sequence of occasions. The Crew Dragon will begin to warmth up because it falls by the environment, 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 really triggers a communications blackout that may last as long as six minutes.

The environment 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 toes, two drogue parachutes will deploy from the capsule when it’s transferring at round 350 miles per hour. These small chutes sluggish 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 toes, 4 massive purple 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, because of 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 dwell protection all through the splashdown, exhibiting scenes from mission management facilities at each NASA and SpaceX. That approach, viewers can observe together with each a part of Behnken and Hurley’s journey dwelling.
