NASA and families of fallen astronauts mark 40th anniversary of space shuttle Challenger accident

NASA honored 25 astronauts lost in Apollo 1, Challenger, and Columbia tragedies with memorials and speeches stressing lessons on safety culture and vigilance.

  • On Thursday, NASA observed its annual Day of Remembrance at the Kennedy Space Center Visitor Complex, part of agency-wide ceremonies held each year on the fourth Thursday of January.
  • The observance commemorates crews from Apollo 1, Challenger, and Columbia's STS‑107, including the Apollo 1 crew, Challenger seven, and Columbia STS‑107 seven.
  • Survivors and relatives led processions and placed flowers at the Space Mirror Memorial, with Alison Smith Balch and family speaking about Michael Smith's lasting legacy.
  • Officials pointed to recent missions and Artemis II planning as evidence the lessons are being applied, with Kelvin Manning, Kennedy Space Center deputy director, urging vigilance 'now more than ever' as rockets fly daily and the next moonshot nears.
  • Investigations into Columbia highlighted underestimated foam risks and led to procedural reviews, while efforts have supported the Astronauts Memorial Foundation Center for Space Education and more than 30 Challenger Centers.
