Spacecraft splashes down off coast of California, paving the way for live astronauts on the next flyby; capsule carries test dummy wearing Israeli radiation tech
CAPE CANAVERAL, Florida — NASA’s new Orion capsule made a blisteringly fast return from the moon Sunday, parachuting into the Pacific Ocean, 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 reentry temperatures of 5,000 degrees Fahrenheit (2,760 degrees Celsius) 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.
Israeli technology was a key part of the mission, with StemRad participating in the mission in a demonstration of its unique product. The company develops radiation protection suits for space explorers, emergency responders, defense forces, nuclear industry workers and medical personnel.
As part of the uncrewed Artemis I mission, StemRad was assessing the protective qualities of the AstroRad, an anti-radiation suit co-developed with Lockheed Martin to protect astronauts’ vital organs from harmful gamma radiation. The suit was placed on a mannequin aboard the Orion.
The humanoid stand-ins, called “anthropometric radiation phantoms,” were provided by the German Aerospace Center (DLR), a partner that will study the AstroRad’s performance in space. Dubbed the Matroshka AstroRad Radiation Experiment (MARE), the study will provide a comparative analysis of two female phantoms — one named Zohar, in a nod to Israel, which wore the AstroRad — and its unprotected counterpart, Helga, named by the German team.
NASA hailed the descent and splashdown as 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 exactly 50 years ago Sunday. 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 program, named after Apollo’s mythological twin sister.
“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 on Sunday, with employees and their families gathering to watch the broadcast of Orion’s homecoming. Next door, the visitor center 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 25,000 mph (40,000 kph) — 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 300 miles (482 kilometers) 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 1.4 million miles (2.25 million kilometers) as it zoomed to the moon and then entered a wide, swooping orbit for nearly a week before heading home.
It came within 80 miles (130 kilometers) of the moon twice. At its farthest, the capsule was more than 268,000 miles (430,000 kilometers) from Earth.
Orion beamed back stunning photos of not only the gray, pitted moon, but also the home planet. As a parting shot, the capsule revealed a crescent Earth — Earthrise — that left the mission team speechless.
Nottingham Trent University astronomer Daniel Brown said the flight’s many accomplishments illustrate NASA’s capability to put astronauts on the next Artemis moonshot. The space agency expects to announce the crew within the next six months. Orion, meanwhile, should be back at Kennedy by the end of this December for further inspections.
“This was the nail-biting end of an amazing and important journey for NASA’s Orion spacecraft,” Brown said in a statement from England.
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.
