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 begin their journey again to Earth inside SpaceX’s new Crew Dragon, bringing an finish to their historic flight to the International Space 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 simple activity, and the 2 astronauts have a protracted journey forward of them earlier than they’re again on strong floor. Once 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 ambiance. That begins a harrowing journey right 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.

Things 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. Right after that, thrusters on the Crew Dragon will do two fast burns with a view 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 website. Right 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 location is one in all seven potential websites round Florida the place the Crew Dragon might land. NASA and SpaceX would slightly the Crew Dragon land on the east facet of Florida, close to Kennedy Space Center in Cape Canaveral, Florida. However, 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 website outdoors of Panama City. If both location works out, this would be the first time a spacecraft has touched down within the Gulf of Mexico.

After that closing burn, it’s a protracted 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 ambiance on Sunday afternoon. At round 1:46PM 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 the entire photo voltaic panels that generate energy for the Crew Dragon throughout flight. But 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 1:51PM 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 ambiance, whereas the capsule’s outer warmth protect ought to defend 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 can last as long as six minutes.

The ambiance helps to cushion the Crew Dragon’s fall, slowing it down immensely. But the capsule wants a bit of 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 transferring at round 350 miles per hour. These small chutes gradual the capsule right down to about 119 miles per hour forward of the principle parachutes deploying. When the Crew Dragon reaches an altitude of 6,000 ft, 4 large pink and white parachutes will deploy to maintain braking the car, permitting it to the touch down gently within the ocean.

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 recent 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 can 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 stay protection throughout the splashdown, displaying 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 residence.
