Overview

  • Families, survivors, and NASA leaders gathered for the Day of Remembrance to honor the seven Challenger astronauts at the launch site.
  • Investigations determined that cold‑weakened O‑ring seals in a right solid rocket booster caused the shuttle to break apart 73 seconds after liftoff in 1986.
  • The ceremony at the Space Mirror Memorial also recognized the Apollo 1 and Columbia crews, whose names are etched alongside other fallen astronauts.
  • Challenger pilot Michael Smith’s daughter, Alison Smith Balch, and his widow, Jane Smith-Holcott, spoke about the lasting impact of the loss on their family.
  • Officials including Kelvin Manning and Bob Cabana called for constant vigilance and open communication as flight rates increase and new missions approach, while the crew’s legacy endures through programs like the Astronauts Memorial Foundation and more than 30 Challenger Centers.
