Operation AXIOM: The Space Age—The 40th Anniversary of S.T.S.-51-L, Aftermath
9 June 1986: The Rogers Commission Report—The presidential commission called the Challenger disaster "an accident rooted in history," strongly criticizing N.A.S.A.'s failure to correct the Solid Rocket Booster O-ring design flaw that had been known about since 1977, & the upside-down safety culture that led to the fatal decision to launch despite the extraordinarily low overnight temperatures.

Commentary: The Commission included chairman William P. Rogers, former U.S. Attorney General & Secretary of State; vice chairman Neil Armstrong, the first Moonwalker; Sally Ride, a Space Shuttle astronaut; Chuck Yeager, the first man to break the sound barrier; & Richard Feynman, winner of the Nobel Prize in Physics; et al.

The Space Shuttle would not return to flight until September 1988.
