The furthest journey in human history ended on Friday evening when NASA Artemis II astronauts returned to Earth after flying around the Moon. The Orion space capsule, named Integrity, crashed into the Pacific Ocean off the coast of San Diego shortly after 5 p.m. Pacific time, ending a 10-day journey of more than 695,000 miles beyond the far side of the Moon and back.
The four-person crew of Artemis II – Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch and Mission Specialist Jeremy Hansen – flew further from Earth than anyone before. reaching 252,756 miles from our home planet.
“Most importantly, we choose this moment to challenge this generation and the next to ensure this record does not last,” he added. he said Canadian astronaut Hansen and his crew broke the previous record of 248,655 miles set during Apollo 13.
Integrity began its fiery descent as the spacecraft hit Earth’s atmosphere at about 40,000 km/h, entering a communications blackout and slowing due to friction as its heat shield reached a temperature of about 3,000 degrees Fahrenheit. The plan was for the capsule to deploy two drogue parachutes to an altitude of about 7,000 feet, slowing it to about 200 miles per hour, and then deploy pilot parachutes that would pull three main parachutes to an altitude of about 2,000 feet. This would further leisurely the spacecraft to about 20 miles per hour before it plunged into the ocean.
During their mission, the Artemis II crew saw things no human had ever seen before. Flying higher above the lunar surface than the Apollo missions, the astronauts were the first to see the entire disk on the far side of the Moon. They also witnessed a solar eclipse from near the Moon, when the sun slipped behind the lunar disk and illuminated it from behind.
“Humans probably didn’t evolve to see what we see,” NASA astronaut Glover said during the eclipse. He and the rest of the crew described a halo of featherlight surrounding the Moon, while one side of the lunar surface was bathed in earth’s featherlight. Venus, Mars and Saturn shone among the stars. “It’s really hard to describe. It’s amazing.”
Artemis II began on April 1, when the crew lifted off from NASA’s Space Center. Kennedy, Florida, atop the 322-foot Space Launch System rocket, the most powerful vehicle to ever carry humans. After performing multiple engine burns while gaining altitude and testing the spacecraft’s manual controls, on the second day of the mission, the crew proceeded to fire the engine, called translunar injection, which sent them on a trajectory to the Moon.
Over the next three days, the crew tested Orion spacecraft systems, practiced donning spacesuits, performed additional heading correction burns, again manually flew the Orion capsule, and prepared for a lunar flyby on the far side of the Moon. They also had problems with discharging sewage from the Orion capsule’s toilet into space.
“We definitely need to fix some of the plumbing,” says NASA Administrator Jared Isaacman he said while talking to the crew.
At 12:41 a.m. ET on April 6, Artemis II entered the lunar zone of influence, where the Moon’s gravity exceeds Earth’s. On that day, the crew approached the Moon, flying to an altitude of approximately 6,000 km above the lunar surface. During the lunar flyby, the crew contacted a team of scientists on the ground, both before and after an approximately 40-minute communications blackout on the far side of the moon, to describe geological features such as craters and canyons.
