The Artemis II crew and NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>NASA successfully conducted a simulated launch day test at the Kennedy Space Center, preparing for their upcoming Moon mission.

The Artemis II crew and teams with NASA’s Exploration Ground Systems Program successfully completed the first in a series of integrated ground system tests at the agency’s Kennedy Space Center in Florida in preparation for their mission around the Moon.

Astronauts Simulate Launch Day Procedures

On Wednesday, NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with CSA (Canadian Space Agency) astronaut Jeremy Hansen, practiced the procedures they will undergo on launch day to prepare for their ride to space.

The crew awoke at their crew quarters inside Kennedy’s Neil Armstrong Operations and Checkouts building before putting on test versions of the Orion crew survival system spacesuits they will wear on launch day. They then departed in NASA’s new Artemis crew transportation fleet to take them to Launch Pad 39B, traversing the nine-mile journey to the pad. Wiseman and Glover headed over in the first electric vehicle as Koch and Hansen followed them in the second.

Upon arrival at the pad, the crew headed onto the mobile launcher and proceeded up the tower to the white room inside the crew access arm. From this area, the astronauts will have access to enter and exit the Orion spacecraft – only for this test, there was no Orion or SLSNASA's Space Launch System (SLS) will be the most powerful rocket they've ever built. As part of NASA's deep space exploration plans, it will launch astronauts on missions to an asteroid and eventually to Mars. As the SLS evolves, the launch vehicle will to be upgraded with more powerful versions. Eventually, the SLS will have the lift capability of 130 metric tons, opening new possibilities for missions to places like Saturn and Jupiter.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>SLS (Space Launch System) rocket.

“When we walked out that crew access arm, I just had images of all those Apollo launches and shuttle launches that I saw as a kid and it was unreal,” Glover said. “I actually had to stop and just stay in the moment to really let it all sink in.”

Artemis II Mission Overview

NASA’s Artemis II mission is a pivotal step in the agency’s ambitious plans to return humans to the Moon and subsequently send them to MarsMars is the second smallest planet in our solar system and the fourth planet from the sun. It is a dusty, cold, desert world with a very thin atmosphere. Iron oxide is prevalent in Mars' surface resulting in its reddish color and its nickname "The Red Planet." Mars' name comes from the Roman god of war.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>Mars. This mission is not just a precursor but also a statement of intent. As NASA’s first flight with crew aboard the new Space Launch System (SLS) rocket and Orion spacecraft, Artemis II is tasked with a journey around the Moon. Its primary goal? To verify that the spacecraft’s systems function seamlessly with a crew in the deep-space environment.

The journey begins at NASA’s Kennedy Space Center in Florida. Four astronauts will board the Orion spacecraft, powered by the SLS rocket in its Block 1 configuration. Post-launch, multiple orbit-raising maneuvers are executed, culminating in Orion being placed on a lunar free return trajectory. This trajectory means the Earth’s gravitational pull will naturally guide Orion home after its lunar flyby.

Throughout its trajectory, the crew will be hands-on, piloting Orion during proximity operations and evaluating various systems. This involves checking life support systems during different metabolic states, like exercise and sleep. They’ll also test communication and navigation systems, ensuring readiness for the lunar flyby. In essence, the long period around Earth is a comprehensive space systems test bed.

As Orion flits past the Moon, the crew will have a unique perspective – viewing both the Moon and Earth from deep space. The lunar flyby, though brief, is a visual testament to the journey’s purpose. Following this, the spacecraft will utilize the gravitational forces of both celestial bodies to efficiently return home, a trip that takes roughly four days.

Artemis II is a prologue. It sets the stage for Artemis III, where history will be made as the first woman and the next man walk on the Moon. NASA’s vision expands even further, with yearly crewed missions planned, all contributing to building capabilities for a long-awaited Mars expedition.
