‘It came alive:’ Astronauts recount wild ride home with SpaceX
US astronauts Bob Behnken and Doug Hurley, home two days from a landmark mission as NASA’s first crew to fly a privately built vehicle into orbit, recounted on Tuesday the loud, jarring ride they experienced through Earth’s atmosphere before a safe landing at sea.
Their splashdown on Sunday in the Gulf of Mexico off Florida
— a mode of return for human space flight last used by NASA 45 years ago — capped the first launch of astronauts from US soil in nine years.
At a news conference from NASA’s Johnson Space Centre in Houston, their first extensive public remarks since coming home, Behnken, 50, and Hurley, 53, described the tense final moments of their 64-day journey.
The duo endured tremendous, jolting forces as the SpaceX-built Crew Dragon, an acorn-shaped vehicle that had carried them to the International Space Station, fired rocket thrusters to slow its descent for re-entry, then pierced the outer atmosphere.
“It came alive,” Behnken told reporters of the nearly 12minute thruster burn. “It doesn’t sound like a machine, it sounds like an animal coming through the atmosphere.”
As the capsule streaked deeper through the sky, atmospheric friction scorched the protective heat shield of the plunging
Crew Dragon to 1,927ºC, slowing its rate of descent to 563km/h.
At that point, the first of two sets of parachutes were deployed, abruptly breaking the capsule’s speed further — an interval that felt “very much like getting hit in the back of the chair with a baseball bat”, Behnken recalled.
“It was a pretty significant jolt,” he said.
The second set of chutes gradually slowed the capsule to a gentle 25km/h rate of descent for a splashdown that ended what Hurley called a “flawless” mission.
Minutes later, recovery teams dispatched by SpaceX, the California-based rocket company founded by billionaire entrepreneur Elon Musk, hoisted the capsule onto a boat. Behnken and Hurley were then flown by helicopter to shore to catch a private flight to Houston.
The two were launched to the
International Space Station from Florida on May 31, embarking on a two-month journey to prove the Crew Dragon capsule safe for transporting humans to and from space.
While bobbing in the water just after splashdown, awaiting recovery teams, Hurley said they completed one final test objective for the mission: “Making prank satellite phone calls to whoever we can get hold of.”
“There was a real reason for it,” Hurley said, in all seriousness, explaining that they needed to prove they could contact mission control using a satphone in case the crew landed from space in an unexpected part of the ocean.
