Artemis II arrives in lunar space ahead of its trip around the Moon
Artemis II and its four-person crew have entered the Moon’s “sphere of influence,” meaning the spacecraft is more affected by lunar gravity than the Earth’s pull. The transition occurred at a distance of 39,000 miles from the Moon, four days, six hours and two minutes into the mission. The next and most important phase will happen tomorrow when the craft loops around the Moon’s far side, taking humans deeper into space than they’ve ever been before. At their apogee, Astronauts Reid Wiseman, Christina Koch, Victor Glover and Canada’s Jeremy Hansen will be 252,757 miles from Earth. That will break the previous record held by the Apollo 13 crew by just over 4,000 miles. They’re the first humans to cross the lunar threshold since 1972’s Apollo 17 moon landing mission. The crew spent this weekend carrying out preparations for their lunar flyby. That included manual piloting demonstrations, reviewing their science objectives for the six-hour observation period and evaluating their space suits, which are there for life support in the event of an emergency and for their return home. But, they've had plenty of time to take in the views, too — and those views sure are spectacular. In the latest series of images shared by the space agency, the astronauts are seen gazing at Earth through the windows of the Orion spacecraft . Orion will reach the moon's vicinity shortly after midnight on Monday, April 6. Later that day, the crew is expected to reach a point farther than any humans
Artemis II, NASA's Orion spacecraft carrying a crew of four astronauts, has entered the Moon's "sphere of influence," marking a significant milestone in its mission to orbit the lunar body. The transition occurred at a distance of 39,000 miles from the Moon, four days, six hours, and two minutes into the journey. This event signifies that the spacecraft is now more influenced by the Moon's gravity than Earth's, setting the stage for the next critical phase of the mission.
The upcoming lunar flyby, scheduled for Monday, April 6, will propel the crew deeper into space than any humans have traveled before. At their apogee, astronauts Reid Wiseman, Christina Koch, Victor Glover, and Canada's Jeremy Hansen will be 252,757 miles from Earth, surpassing the previous record held by the Apollo 13 crew by over 4,000 miles. This achievement marks the first time humans have crossed the lunar threshold since the Apollo 17 mission in 1972.
Over the weekend, the crew has been meticulously preparing for the lunar flyby. These preparations included manual piloting demonstrations, reviewing scientific objectives for the six-hour observation period, and evaluating their space suits, which serve as crucial life support systems in case of emergencies and for their return journey. Despite the busy schedule, the astronauts have also taken the opportunity to marvel at the breathtaking views from the Orion spacecraft. Recent images shared by NASA capture the crew gazing at Earth through the spacecraft's windows, offering a poignant reminder of their unique vantage point in space.
Orion is expected to reach the Moon's vicinity shortly after midnight on April 6. Later that day, the crew will break another record, traveling farther from Earth than any humans have before, surpassing the 248,655-mile mark set by the Apollo 13 astronauts in 1970. Mission specialist Christina Koch, the first woman to perform a spacewalk from the International Space Station, is among those taking in the awe-inspiring vistas.
The lunar observation period will commence at 2:45 PM ET, followed by a brief period of communication loss when the spacecraft will be behind the Moon. The closest approach to the lunar surface is anticipated at 7:02 PM, with Orion passing within 4,066 miles of the Moon's surface. From this distance, the crew will have a spectacular view of the lunar landscape, highlighting the vastness of space and the importance of this mission in rekindling humanity's exploration of the cosmos.
As Artemis II continues its journey, it represents a pivotal step toward NASA's goal of establishing a sustainable presence on the Moon and eventually sending astronauts to Mars. This mission not only celebrates the legacy of past spaceflights but also opens new frontiers for future generations of explorers. The crew's successful navigation of the lunar sphere of influence and their upcoming record-breaking flyby underscore the dedication and innovation of those working to advance space travel and scientific discovery.
