Artemis II: Inside NASA's Nerve Center for Moon Mission
26 Mar
Summary
- The Artemis II mission will send four astronauts on a 10-day lunar journey.
- Launch director Charlie Blackwell-Thompson oversees countdown and launch criteria.
- Flight director Rick Henfling manages the Orion spacecraft's return to Earth.
The historic Firing Room 1 at NASA's Kennedy Space Center is preparing for the Artemis II mission, aiming to send four astronauts on a 10-day journey around the moon. Launch director Charlie Blackwell-Thompson, a trailblazer as NASA's first female launch director, will oversee the final countdown, a process requiring intense focus from her team.
This mission marks humanity's return to lunar space after 50 years. Blackwell-Thompson manages the critical launch commit criteria, ensuring all systems are 'go' before liftoff. She has a personal tradition, wearing green bracelets as a symbol of her full commitment.
Following liftoff, Jeff Radigan, lead flight director, and his crew at Mission Control in Houston will take over. They will monitor the Orion spacecraft and its crew throughout their 685,000-mile journey. Lead entry flight director Rick Henfling is primarily responsible for Orion's safe return to Earth.
Henfling's team will meticulously check the spacecraft's performance in the initial hours after launch. They are particularly focused on how Orion will perform with astronauts onboard, addressing aspects like life support and navigation. A key milestone is the translunar injection burn, 24 hours into the mission.
Communication will be lost when Orion travels behind the moon for about 45 minutes, a tense period for mission control. However, this is anticipated to be a unique moment for the crew, potentially echoing the iconic 'Earthrise' photo. Henfling expressed confidence in the team's ability to manage any issues.
NASA astronaut Stan Love will serve as the Capsule Communicator (CapCom), relaying information to the astronauts. Just before reentry, Henfling will have a less formal discussion with the crew to address their entry procedures. The Orion spacecraft will face extreme heat during reentry, traveling at approximately 25,000 miles per hour.
Concerns have been raised about Orion's heat shield, which showed unexpected damage after the Artemis I mission. NASA has modified the reentry trajectory to create a more benign environment for the heat shield. Henfling stated he has high confidence in the engineering and testing that has been conducted.
Flight directors, including Henfling, regularly simulate various scenarios, including potential fires aboard the spacecraft. Their training emphasizes critical thinking to respond to unforeseen problems. Henfling views the mission as a testament to human collaboration towards a shared objective.
