How to watch the astronauts during the historic Artemis II splashdown off the coast of California on Friday

NASA’s Artemis II to Splash Down off San Diego

Residents of California have a unique chance to witness a historic event when NASA’s Artemis II mission splashes down near San Diego this Friday. The crew, returning from a ten-day mission to explore the moon, is expected to make their descent at around 5:07 p.m. on April 10.

The Orion capsule will land in the Pacific Ocean, approximately 70 to 80 miles offshore, between Catalina Island and San Clemente Island. By Wednesday, the crew had already begun their journey back, having ventured further from Earth than anyone before them.

Francisco Contreras, a resident of Oceanside and director of the San Diego Astronomical Society, suggested that locals wanting to catch a glimpse should make their way to the coast. He noted, “It’s so high up and far away that it should be visible from the coast. It shouldn’t need to be right next to San Clemente.” He added that the best chance for a view would be if the northwest sky is clear.

The San Diego Air and Space Museum plans to host watch parties, featuring activities aimed at engaging kids. Given San Diego’s naval roots, both Naval Air Station Coronado North Island and Naval Station San Diego will assist in recovering the capsule.

A naval helicopter unit from Naval Air Station Kitajima will monitor the capsule as it re-enters Earth’s atmosphere and subsequently recover the four astronauts for their evaluation after landing. The USS John P. Murtha, a ship based in San Diego, will be stationed to retrieve the astronauts once the capsule enters the water.

The Navy highlighted the ship’s special capabilities, stating it will play a vital role in gathering important data for future Artemis missions. “We’ve collaborated with NASA for about 12 years now,” remarked Capt. Neil Krueger from Naval Base San Diego.

He further explained the capsule’s landing: “They come in quickly, deploying parachutes, and they hit around 20 miles per hour as they enter the water.” A mobile dive team is prepared to open the capsule and transfer it to a floating raft, which will then be airlifted to the ship for further analysis.

Krueger indicated that spectators might witness the ship as it returns to shore on Saturday morning. While the crew is undoubtedly eager to return home, they face a critical moment as the Orion capsule enters Earth’s atmosphere, where temperatures soar to 5,000 degrees Fahrenheit. The success of this return hinges on the capsule’s heat shield.

This heat shield, designed to shed material at a controlled rate, is 16.5 feet wide and intended to protect the crew during the re-entry process. Adjustments were made to the shield’s coating after issues were observed in the unmanned Artemis I mission in 2022, with thinner material now employed to better manage high temperatures during re-entry.

“The previous shield had significant damage,” reports indicate, but despite that, the cabin temperature remained safe during Artemis I. As for Artemis II, NASA is also watching weather conditions, as rain and thunderstorms could impact Friday’s planned landing. The hope is that everything aligns for a safe recovery.
