Artemis II splashdown: When it lands, risks and how to watch live

Lead

After a historic 10-day journey around the Moon, the four Artemis II astronauts are preparing to return to Earth on Friday, culminating in a high-speed re-entry and splashdown in the Pacific Ocean off the coast of San Diego. The mission, which marked the furthest human travel from Earth, will test critical systems for future lunar landings.

According to NASA, the Orion spacecraft, named Integrity by the crew, will re-enter Earth's atmosphere at approximately 00:07 GMT on April 11 (8:07 p.m. ET on April 10) and splash down in the Pacific. The spacecraft will be traveling at nearly 24,000 mph before its final descent, as reported by multiple sources.

Coverage Comparison

Coverage from Al Jazeera and The Guardian provides complementary details on the mission's final stage. Al Jazeera emphasizes the "high-stakes" nature of the re-entry, focusing on the heat shield's role and expert concerns about its design. The Guardian offers a more detailed timeline of the spacecraft's return, including specific times for module separation and parachute deployment, and highlights the precision required for a successful re-entry.

Both outlets quote NASA Associate Administrator Amit Kshatriya's address to engineers: "To every engineer, every technician that's touched this machine — tomorrow belongs to you. The crew has done their part. Now we have to do ours."

Key Claims

• The Artemis II crew, consisting of NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen, will return to Earth on Friday following a 10-day lunar flyby mission. This is reported by multiple sources.
• The Orion capsule will be traveling at nearly 24,000 mph before splashing down several miles off the coast of San Diego, according to The Guardian.
• NASA has set strict "go" conditions for splashdown, including wave heights below six feet, winds under 28.7 mph, and no rain or lightning within a 30-nautical-mile radius, as reported by Al Jazeera.
• Amit Kshatriya emphasized the importance of precision, stating that the team has "less than a degree of an angle" to hit the correct flight path, as quoted in both Al Jazeera and The Guardian.
• Jeff Radigan, lead flight director, outlined the timeline: crew module and service module separation at 4:33 p.m. PT, with the service module burning up in the atmosphere; entry interface at 4:53 p.m. PT; and splashdown at 5:07 p.m. PT, as reported by The Guardian.
• The splashdown will occur far off the southern California coast, with the USS John P. Murtha ready to assist recovery operations, according to multiple sources.
• The heat shield is a critical component protecting astronauts from extreme temperatures during re-entry, as reported by Al Jazeera.
• Some experts have raised concerns about the heat shield's design. Aerospace engineer Charles Camarda, a former NASA astronaut, stated he does not believe the crew should launch with the current heat shield, a claim carried by a single outlet and not yet independently verified.
• The Artemis II mission is significant for testing systems for future crewed moon landings, including Artemis III, as reported by Al Jazeera.
• The crew will experience intense gravitational forces during re-entry, typically peaking between three and seven times normal Earth gravity, as reported by The Guardian.

Perspectives

NASA's Official Perspective

NASA officials, including Associate Administrator Amit Kshatriya and Lead Flight Director Jeff Radigan, emphasize the thorough preparation and precision required for the re-entry. They express confidence in the mission's readiness, acknowledging the complexity of the operation and the coordination of multiple teams.

Expert Concerns on Heat Shield

Some experts, such as aerospace engineer Charles Camarda, have voiced concerns about the Orion heat shield's design, suggesting potential risks during re-entry. These concerns, while not widespread, highlight the challenges of ensuring crew safety during the high-speed return.

Public and Safety Considerations

Jeff Radigan cautioned the public to avoid the recovery area due to a large exclusion zone and falling debris, emphasizing the need for safety during the operation. This reflects NASA's commitment to ensuring the safe recovery of the crew and spacecraft.

Conclusion

The Artemis II mission's final stage represents a critical test of NASA's capabilities for future lunar exploration. With careful coordination and precision, the agency aims to safely bring the crew home, paving the way for Artemis III and beyond.
