U.S. 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 splash-down on Sunday in the Gulf of Mexico off Florida – a mode of return for human spaceflight last used by NASA 45 years ago – capped the first launch of astronauts from U.S. soil in nine years.
At a news conference from NASA’s Johnson Space Center 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 12-minute 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 3,500 Fahrenheit (1,927 Celsius), slowing its rate of descent to 350 mph (563 kph).
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.
