Critics say NASA failed to learn lessons
CAPE CANAVERAL, Fla. – Some of the same “disturbing” traits that contributed to the Columbia tragedy were still present in the months leading up to the shuttle Discovery’s liftoff, seven members of a larger oversight panel said Wednesday in a scathing critique.
“We expected that NASA leadership would set high standards for post-Columbia work,” the panel members wrote. “We were, overall, disappointed.”
The minority report said poor leadership made the shuttle’s return to space on July 26 more complicated, expensive and prolonged than it needed to be. So much emphasis was placed on trying to meet unrealistic launch dates that some safety improvements were skipped, said the group.
“Another disturbing trait that we observed was that personalities were allowed to dominate over strict process,” the seven panel members added.
The critics include a former shuttle astronaut, former undersecretary of the Navy, former Congressional Budget Office director, former moon rocket engineer, retired nuclear engineer and two university professors.
“NASA needs to learn the lessons of its past … lessons provided at the cost of the lives of seventeen astronauts,” they said, referring to the seven killed aboard Columbia and 10 others who died in the Challenger and Apollo 1 accidents years earlier.
The seven critics are part of the 26-member task force that monitored NASA’s progress in meeting the recommendations set forth by the Columbia accident investigators. The entire task force concluded in late June in an advance summary – just a month before Discovery’s liftoff on the first mission since the Columbia disaster – that the space agency failed to satisfy three of the 15 return-to-flight recommendations.
Those three failed recommendations were arguably the most critical: an inability to prevent dangerous pieces of foam and ice from breaking off the fuel tank during launch; an inability to fix any damage to the shuttle in orbit; and a failure to make the shuttle less vulnerable to debris strikes.
As it turned out, a large, potentially deadly chunk of foam insulation broke off Discovery’s modified fuel tank during liftoff. Unlike in Columbia’s tragic case, the piece did not hit Discovery. Nevertheless, NASA grounded its shuttle fleet.
The next shuttle mission had been scheduled for September, but now is expected to occur no earlier than March.
The co-chairmen of the task force, retired Apollo astronaut Thomas Stafford and retired shuttle astronaut Richard Covey, refused to comment Wednesday on the observations of individual panel members.
However, Covey and a NASA spokesman noted that space agency chief Michael Griffin requested that all individual comments, including the 20-page critique from the seven panel members, be included in the official task force report.
The seven said NASA should have done detailed engineering reviews of the Columbia accident investigators’ recommendations before committing to short-term launch dates. That way, they said, the space agency would have better understood the foam loss and seriously considered alternative approaches, such as a completely redesigned fuel tank or hardening of the shuttle’s skin.
Discovery’s original launch date, before Columbia’s catastrophic return on Feb. 1, 2003, was March 1 of that year. That date ended up changing 14 times.
As early as September 2003, NASA told the task force that some technical work was not being performed because they could not meet the launch schedule, the seven members noted. “Too often we heard the lament: ‘If only we’d known we were down for two years we would have approached this very differently.”’
Discovery astronaut Andrew Thomas said Wednesday that having so many launch dates was indeed “a serious issue.”
