NEPHI, Utah (AP) — Roger Boisjoly, a NASA contractor who repeatedly voiced concerns about the space shuttle Challenger before it exploded, has died. He was 73.
Boisjoly died of cancer on Jan. 6 in southwest Utah, his wife Roberta Boisjoly said.
CAPE CANAVERAL, Fla. -- Hundreds gathered at NASA's launch site Friday to mark the 25th anniversary of the Challenger disaster, receiving words of hope from the widow of the space shuttle's commander.
The chilly outdoor ceremony drew space agency managers, former astronauts, past and present launch directors, family and friends of the fallen crew -- and schoolchildren who weren't yet born when the space shuttle carrying a high school teacher from Concord, N.H.., erupted in the sky.
