Hermes Crew Rescue of Watney

Lore & Background

The rescue of Mark Watney was not a single event but the culmination of a series of desperate gambits. After the Ares 3 crew departed Mars during a dust storm, believing Watney dead, he survived alone using his botany skills and the Hab's resources. When NASA discovered he was alive, a global effort began to keep him alive and bring him home. The rescue plan evolved multiple times, from sending supplies via the Chinese Taiyang Shen booster to the risky 'Iron Man' maneuver where Watney would launch himself in a modified MAV to rendezvous with the Hermes.

In Their Own Story

The Hermes crew, having already sacrificed their return to Earth to save Watney, now faced their most dangerous moment. Commander Lewis piloted the ship on a slingshot trajectory around Earth, bleeding off speed to intercept Watney's makeshift ascent. Inside the MAV, Watney felt the G-forces crush him—his vision narrowed to a tunnel, ribs straining—as he rocketed toward orbit. The crew watched his trajectory on their screens, knowing that if he missed by even a few meters, he would drift forever, a ghost in the black. With seconds to spare, Watney fired his thruster—a jury-rigged contraption of duct tape and spare parts—and the Hermes crew saw his suit tumbling toward them, a lone speck against the stars. They scrambled to the airlock, and Lewis herself grabbed his suit, her gloved fingers locking onto his harness, pulling him inside. For a moment, they all floated in silence, breathing in the recycled air of the Hermes. Then Watney whispered, 'I'm home.'

NASA initially resists but eventually supports the plan, knowing the political and human stakes. The critical phase involves the 'Iron Man' maneuver: Watney must launch the MAV (Mars Ascent Vehicle) with a modified trajectory to intercept the Hermes as it passes Mars at over 8 kilometers per second. The crew of the Hermes, led by Commander Lewis, executes a complex orbital rendezvous, using Earth's gravity to slow their approach. Watney's launch is violent—he's slammed into his seat at 12 Gs—and he must manually adjust his course using a thruster from the Hab, firing it in short bursts to close the gap. The Hermes crew catches him in the airlock as he drifts past, his suit scraping the hull. The impact is profound: it demonstrates the power of international cooperation, as the Chinese space program contributed the Taiyang Shen booster, and the crew's willingness to risk everything—their careers, their lives—for one person. The rescue solidifies Watney's status as a symbol of human resilience and the value of teamwork in space exploration.

Did You Know?

• The rescue plan was nicknamed the 'Iron Man' maneuver because Watney had to use a thruster to fly himself to the Hermes, similar to the superhero's flight—except his 'suit' was a patched-together EVA rig with a jury-rigg
• Commander Lewis personally pulled Watney into the Hermes airlock, a moment that became iconic among fans—a visceral reminder that even in the cold vacuum of space, a human hand can make the difference.
• The Chinese space agency's contribution of the Taiyang Shen booster was crucial, highlighting international cooperation in the story—without that booster, the Hermes would have lacked the delta-v to intercept Watney's or
