Nasa’s Orion capsule blazes home from test flight to moon

Nasa’s Orion capsule has made a blisteringly fast return from the moon, parachuting into the Pacific off Mexico to conclude a test flight that should clear the way for astronauts on the next lunar flyby.

The incoming capsule hit the atmosphere at Mach 32, or 32 times the speed of sound, and endured re-entry temperatures of 2760C before splashing down west of Baja California near Guadalupe Island. A Navy ship quickly moved in to recover the spacecraft and its silent occupants - three test dummies rigged with vibration sensors and radiation monitors.

Nasa hailed the descent and splashdown as spectacular and close to perfect.

“I’m overwhelmed,” Nasa administrator Bill Nelson said from Mission Control in Houston. “This is an extraordinary day ... It’s historic because we are now going back into space - deep space - with a new generation.”

The space agency needed a successful splashdown to stay on track for the next Orion flight around the moon, currently targeted for 2024. Four astronauts will make the trip. That will be followed by a two-person lunar landing as early as 2025.

Astronauts last landed on the moon 50 years ago. After touching down on December 11, 1972, Apollo 17′s Eugene Cernan and Harrison Schmitt spent three days exploring the valley of Taurus-Littrow, the longest stay of the Apollo era. They were the last of the 12 moonwalkers.

Orion was the first capsule to visit the moon since then, launching on Nasa’s new mega moon rocket from Kennedy Space Center on November 16. It was the first flight of Nasa’s new Artemis moon programme, named after Apollo’s mythological twin sister.

“Splashdown! From Tranquility Base to Taurus-Littrow to the tranquil waters of the Pacific, the latest chapter of Nasa’s journey to the moon comes to a close. Orion back on Earth,” announced Mission Control commentator Rob Navias.

While no one was on the $4 billion test flight, Nasa managers were thrilled to pull off the dress rehearsal, especially after so many years of flight delays and busted budgets. Fuel leaks and hurricanes conspired for additional postponements in late summer and fall.

In an Apollo throwback, Nasa held a splashdown party at Houston’s Johnson Space Center, with employees and their families gathering to watch the broadcast of Orion’s homecoming. Next door, the visitor centre threw a bash for the public.

Getting Orion back intact after the 25-day flight was Nasa’s top objective. With a return speed of 40,000km/h - considerably faster than coming in from low-Earth orbit - the capsule used a new, advanced heat shield never tested before in spaceflight. To reduce the gravity or G loads, it dipped into the atmosphere and briefly skipped out, also helping to pinpoint the splashdown area.

All that unfolded in spectacular fashion, Nelson noted, allowing for Orion’s safe return.

The splashdown occurred more than 482km south of the original target zone. Forecasts calling for choppy seas and high wind off the Southern California coast prompted Nasa to switch the location.

Orion logged 2.25 million kilometres as it zoomed to the moon and then entered a wide, swooping orbit for nearly a week before heading home.

It came within 130km of the moon twice. At its farthest, the capsule was more than 430,000km from Earth

Orion beamed back stunning photos of not only the grey, pitted moon, but also the home planet. As a parting shot, the capsule revealed a crescent Earth - Earthrise - that left the mission team speechless.

The moon has never been hotter. Just hours earlier Sunday, a spacecraft rocketed toward the moon from Cape Canaveral. The lunar lander belongs to ispace, a Tokyo company intent on developing an economy up there. Two US companies, meanwhile, have lunar landers launching early next year.
