Slamming into the atmosphere at more than 30 times the speed of sound, NASA’s Orion spacecraft blazed a trail over the Pacific Ocean on Friday, returning home with four astronauts and safely capping humanity’s first voyage to the Moon in nearly 54 years.

Temperatures outside the capsule builtup to some 5,000 degrees Fahrenheit as a sheath of plasma enveloped the Orion spacecraft, named Integrity, and its four long-distance travelers, temporarily blocking radio signals the Moon ship and Mission Control in Houston. Flying southwest to northeast, the spacecraft steered toward a splashdown zone southwest of San Diego, where a US Navy recovery ship held position to await the crew’s homecoming. Ground teams regained communications with Orion commander Reid Wiseman after a six-minute blackout.

Airborne tracking planes beamed live video of Orion’s descent back to Mission Control, showing the capsule jettison its parachute cover and deploy a series of chutes to stabilize its plunge toward the Pacific. Then, three larger main chutes, each with an area of 10,500 square feet, opened to slow Orion for splashdown at 8:07 pm EDT Friday (00:07 UTC Saturday).
