STS-114 Discovery, commanded by Eileen Collins, landed after completing the post-Columbia Return to Flight safety tests and ISS resupply operations.
Space Shuttle Discovery mission STS-114, commanded by Eileen Collins, landed on August 9, 2005, concluding NASA's pivotal 'Return to Flight' mission following the 2003 Columbia disaster.
During the nearly two-week mission, Collins's crew successfully tested new safety procedures, including using the shuttle's robotic arm and a sensor boom to inspect the orbiter's thermal protection system for damage, and conducted the first in-space repair of a Shuttle's thermal tiles. The mission also delivered supplies and equipment to the International Space Station and returned with return cargo and a retiring crew member.
The safe landing of Discovery, after a mission fraught with additional scrutiny due to foam-shedding concerns similar to those that caused the Columbia tragedy, was a moment of profound relief and validation for NASA. Collins's composed and exacting command throughout the flight—her second time leading a Shuttle mission—reaffirmed her position as one of the most capable and trusted astronauts in NASA's history.
This mission marked the final spaceflight of Collins's career; she retired from NASA the following year. Her leadership during this uniquely high-stakes mission left a lasting legacy on subsequent Shuttle safety practices and inspection protocols used throughout the remainder of the Shuttle program until its retirement in 2011.
