Warship Portland Steaming Home With Deep Space Traveler

The amphibious warship Portland is steaming for San Diego, a world-famous deep space traveler safely stowed in its well deck.

At 9:40 p.m. local time on Sunday, Dec. 11, NASA’s uncrewed Orion spacecraft’s parachutes unfurled inside Earth’s atmosphere and the module splashed down in the Pacific Ocean off the Baja California coast.

That capped a 25-day Artemis I mission that traveled 1.1 million nautical miles, from Kennedy Space Center in Florida and then a long swing around the moon and back to our planet.

“We followed the vehicle as it made its journey around the moon, and we held our breaths all morning because Orion went through its de-orbit and splashdown paces,” Janet E. Petro, the director of the John F. Kennedy Space Center, told reporters during a Sunday press conference. “It really was surreal.”

Portland is slated to arrive at US Naval Base San Diego on Tuesday, with crews scheduled to unload Orion two days later. The module will then begin its journey back to Florida.

NASA reported that mission control at Houston’s Johnson Space Center spent roughly two hours performing tests while the capsule bobbed in open water, downloading data about the spacecraft.

A key interest for researchers is how well Orion endured the blistering heat of reentry through Earth’s atmosphere — at around 5,000 degrees Fahrenheit, about half as hot as the sun's surface — which is why NASA ordered the recovery team to take many photos of the spacecraft.

Navy divers then attached a winch line and several tending lines to the module, and Portland’s crew began slowing heaving in the spacecraft before nestling it in the well deck’s specially designed cradle.

After ocean water drained from the well deck, Orion was secured for the journey to San Diego, which is going a lot slower than the spacecraft when it returned to Earth.

During its 20-minute plunge toward the Pacific, Orion was falling at nearly 22,000 knots.

On the 19th day of the Artemis I mission, Dec. 4, 2022, a camera mounted on the Orion spacecraft captured the moon just in frame as Orion prepared for its return powered flyby on Dec. 5, when it passed approximately 79 miles above the lunar surface. NASA photo.

But it hit the water at 17 knots. And Howard Hu, NASA’s program manager for the Artemis missions, said Orion splashed down only 2.1 nautical miles from its target.

That was 2.4 nautical miles closer than the space agency required, so he was happy.

The recovery team ranged from the sailors on board Portland to Space Force weather specialists, and engineers and technicians from Lockheed Martin Space Operations and NASA.

US 3rd Fleet announced the Independence-class littoral combat ship Montgomery supported Portland during the recovery operation.

NASA’s chief flight director, Emily Nelson, said Orion's odyssey had “exceeded all expectations,” which means her researchers can “start looking ahead at Artemis II, and thinking about how else we can push the boundaries on this flight.”

Slated for mid-2024, the second flight of NASA’s Space Launch System will feature four RS-25 engines churning more than 2 million pounds of thrust to ferry three US astronauts and a Canadian crew member on a 10-day lunar flyby.

The crew is expected to be named in 2023.

Artemis III is intended to return astronauts to the lunar surface in 2025, with a journey to Mars launching closer to 2040, officials said.

“A lot of this will depend on the development of new technologies and the ability to sustain humans for a long time along the way,” NASA administrator Bill Nelson told reporters.
