Columbia astronaughts might have inspected wing in spacewalk
The Columbia Accident Investigation Board (CAIB) officially released volumes II-IV of its Final Report. Today's releases contain one tidbit that compels me to acknowledge that a public statement I made last February was partially wrong. With the benefit of eight months' hindsight, CAIB has concluded that the Columbia astronaughts might have undertaken a highly risky two-man spacewalk to inspect the damage to the spacecraft's left wing — "if one of them had used the other as a ladder," in the words of one New York Times article (Reports Detail a Hypothetical Shuttle Rescue).
In a post to CTY-L on 11 February 2003, I stated (wrongly, it turns out) that the Columbia astronaughts could not have inspected or repaired the damage. While CAIB concluded that the astronaughts might have inspected the damage, the report does not suggest they could have repaired it in space, or that they should have attempted to do so. Indeed, the shuttle did not have the appropriate materials or tools on board to carry out such a repair. See, e.g., this Washington Post article: "Astronauts on Columbia and engineers in Mission Control were not aware of the extent of damage to the shuttle wing. But officials said that, in any case, there was no equipment on the shuttle to patch the wing even if the problem were recognized." (Article: Paint Brush May Aid in Repair of Shuttle)
