NASA's Artemis II Mission Reenters Atmosphere Off San Diego Coast Friday Evening

NASA's Artemis II mission is set to reenter Earth's atmosphere off the coast of San Diego on Friday evening. The U.S. Geological Survey stated that Southern Californians may hear a sonic boom generated as the capsule slows down and breaks the sound barrier.

The sonic boom's audibility range remains uncertain, including how far up and down the coast or inland it may be heard. The U.S. Geological Survey said the boom depends on various atmospheric conditions. The agency is requesting public assistance through its 'Did You Feel It' survey to collect reports on whether the boom was heard.

Officials noted that such data will assist in predicting sonic booms from sources like meteorites, space debris, military supersonic tests, and private aerospace activities. The mission marks the first crewed lunar trip in 50 years.

indicated limited confidence in visibility from the ground. However, officials stated that favorable weather conditions may allow observers along the Southern California coast to see a faint light on the western horizon during reentry. The visible streak would last less than one minute.

The mission's splashdown is planned in the Pacific Ocean off San Diego following the reentry. The U.S. Geological Survey will contribute to scientific understanding of sonic boom propagation for future missions and events.
