“The trampoline is working”—SpaceX returns human spaceflight to America<\/a><\/div>\n<\/div>\n<\/div>\n Now, NASA would like the crew to come home and complete the final, key objective of the test flight, splashing down safely in the ocean. Nominally, this is scheduled for the afternoon of Sunday, August 2.<\/p>\n A final target date and time will be selected on Wednesday, during a “Return Flight Readiness Review,” which will consider both the health of the spacecraft and weather. There are seven potential splashdown zones for Dragon around the state of Florida, in both the Gulf of Mexico and Atlantic Ocean. Among the criteria for weather<\/a> are winds less than 16.5km\/hour, calm seas, and a low probability of rainfall.<\/p>\n A decision on where to splash down will come about six hours before undocking, but a final call on whether to actually undock may not be made until the final minutes before departure. Depending on the splashdown location chosen, it will take between six and 30 hours for the crew to return to Earth after undocking.<\/p>\n <\/p>\n Crew Dragon will perform two very short burns to separate from the station, and then there will be four slightly longer burns to move Endeavour<\/em> farther away and begin the journey home. During this time, NASA and SpaceX will continue to monitor weather in the splashdown location, and if conditions deteriorate a decision will be made to wait 24 to 48 hours for another landing attempt.<\/p>\n When a final decision is made to commit to a landing, the Dragon capsule will shed its trunk and perform a deorbit burn. During the reentry process Dragon will be subjected to temperatures as high as 1,950°C, relying on its forward heat shield to absorb these extreme conditions.<\/p>\n After nearly a month in space, NASA seems really happy with Crew Dragon<\/a><\/div>\n<\/div>\n<\/div>\n Once in the lower atmosphere, the capsule’s drogue parachute will deploy at about 5.5km above the planet’s surface, followed by the main parachutes at an altitude of about 2km. After splashing down, Hurley and Benhken will remain inside Dragon for 30 to 60 minutes, depending on sea states, before either the Go Searcher<\/em> and the Go Navigator<\/em> recovery ship hoists the spacecraft onto its main deck.<\/p>\n After an initial checkout on the ship, in most scenarios, the crew will board a helicopter to fly to Cape Canaveral. On land, they will take a NASA plane that will bring them to Ellington Field, near their homes in Houston. And then, finally, they will be done flying for a while.<\/p>\n<\/section>\n Tags:<\/b> ERIC BERGER <\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"![\"Approximate](\"https:\/\/cdn.arstechnica.net\/wp-content\/uploads\/2020\/07\/splahsdown-980x476.jpg\")

So far, this test flight has been a great success. Nearly two months have passed since a Crew Dragon spacecraft carrying two astronauts blasted off the face of the Earth and delivered NASA astronauts Doug Hurley and Bob Behnken into orbit. Now, it’s time to come home. So far, this test flight of the SpaceX-built crew spacecraft … Continue reading NASA, SpaceX preparing to bring Crew Dragon home this week<\/span><\/a> Continue Reading
