Orion is scheduled to splash down off the coast of Baja California around 12:40 p.m. EST on Sunday (Dec. 11).

NASA’s Artemis 1 Orion spacecraft will return to Earth on Sunday (Dec. 11) after nearly a month in space, and you can watch the homecoming live. 

Artemis 1’s uncrewed Orion capsule is scheduled to splash down in the Pacific Ocean off the coast of Baja California Sunday around 12:40 p.m. EST (1740 GMT). 

You can watch live coverage of Orion’s reentry here at Space.com courtesy of NASA, or directly via the space agency (opens in new tab). Coverage will start at 11 a.m. EST (1600 GMT).

Orion launched atop a Space Launch System (SLS) rocket on Nov. 16, kicking off the highly anticipated Artemis 1 mission. 

The capsule slipped into lunar orbit on Nov. 25, then left on Dec. 1. Four days later, Orion fired its main engine in a 3.5-minute burn — its longest of the mission — during a close lunar flyby to head back to its home planet.

The 25.5-day-long Artemis 1 mission will end on Sunday, 50 years to the day that Apollo 17 astronauts Gene Cernan and Harrison Schmitt touched down on the lunar surface. The duo departed on Dec. 14, 1972, and no humans have been back to the moon since.

If all goes according to plan, Orion will hit Earth’s atmosphere over the Pacific Ocean at about 12:20 p.m. EST (1720 GMT) on Sunday while traveling 25,000 mph (40,000 kph). This tremendous speed will generate a lot of friction; Orion’s heat shield will have to handle temperatures up to 5,000 degrees Fahrenheit (2,800 degrees Celsius) — about half as hot as the surface of the sun.

The capsule will bounce off the upper atmosphere briefly and then come back down, like a rock skipping across the surface of a pond. After this skip, Orion will descend through the atmosphere under parachutes, splashing down off the coast of Baja California at about 12:40 p.m. EST (1740 GMT). A U.S. Navy ship, the USS Portland, will be waiting in the vicinity to retrieve the spacecraft and haul it to port in San Diego.

Reentry will begin over the open Pacific, far off the coast of South America, and Orion will head north from there. The remoteness of the capsule’s path, combined with the timing — that is, during daylight hours — make this reentry a very hard target for observers on the ground, even those close to the splashdown site.

“Is anybody going to be able to see that off Baja?” Artemis 1 Flight Director Judd Frieling said during a press conference on Thursday (Dec. 8). “There’s always a chance, but we’re pretty far off the coast there, so I doubt it — unless you’re out there in a boat, 100 miles offshore or so.”

Nearby observers may get aural evidence that reentry has begun, however.

“You’re more likely to hear the sonic boom as the vehicle approaches than anything,” Artemis 1 Mission Manager Mike Sarafin said during Thursday’s briefing.

Artemis 1 is a shakeout cruise for the SLS, Orion and their associated ground systems. If everything goes well on Sunday, NASA can begin gearing up for Artemis 2, which will send astronauts around the moon in 2024.

Artemis 3 is scheduled to put boots down near the lunar south pole in 2025 or 2026. Future missions in NASA’s Artemis program will build a research base in that region, which is thought to be rich in water ice.

The agency wants to have to this outpost up and running by the end of the 2020s. NASA plans to use the knowledge gained from these moon efforts to help get astronauts to Mars by the late 2030s or early 2040s.

Power on the Moon. What Will it Take to Survive the Lunar Night?

With the help of international and commercial partners, NASA is sending astronauts back to the Moon for the first time in over fifty years. In addition to sending crewed missions to the lunar surface, the long-term objective of the Artemis Program is to create the necessary infrastructure for a ...

What is the true nature of our quantum reality?

When it comes to understanding the Universe, scientists have traditionally taken two approaches in tandem with one another. On the one hand, we perform experiments and make measurements and observations of what the results are; we obtain a suite of data. On the other hand, we construct theories and ...

Planetary Interiors in TRAPPIST-1 System Could be Affected by Solar Flares

In a recent study published in The Astrophysical Journal Letters, an international team of researchers led by the University of Cologne in Germany examined how solar flares erupted by the TRAPPIST-1 star could affect the interior heating of its orbiting exoplanets. This study holds the potential to help us ...

SpaceX’s last Starlink launch of 2022 is a bit of a mystery

In a strange twist, SpaceX says that its next Starlink mission will launch 54 satellites into low Earth orbit (LEO), implying that they’re roughly the same size as the V1.5 satellites it’s already launching – not the larger V2 or V2 Mini satellites hinted in recent FCC filings. However, ...

Is Mining in Space Socially Acceptable?

Traditional mining has been subject to a negative stigma for some time. People, especially in developed countries, have a relatively negative view of this necessary economic activity. Primarily that is due to its environmental impacts – greenhouse gas emissions and habitat destruction are some of the effects that give ...
