NASA Releases Preliminary Lunar Science Report for Artemis II

NASA published the Artemis II Preliminary Lunar Science Report after the crew's 9-day, 1-hour, 32-minute flight around the Moon in April 2026. Astronauts observed a 54-minute solar eclipse, nighttime meteorite impacts and stars free of light pollution.

• The flight lasted 9 days, 1 hour and 32 minutes with a four-astronaut crew
• The eclipse behind the Moon lasted 54 minutes, longer than any on Earth
• Meteors up to 5 cm across produced the faintest flashes ever seen with the naked eye
• An April 2 Earth photo captured auroras, a Saharan dust plume and city lights
