Shuttle Alantis has a bolt problem


Among the many items to be discussed during the meeting is whether engineers need to replace a set of four bolts connecting Atlantis’ primary data and video antenna to the upper right side of the orbiter’s payload bay.

“I know they’re going to present it and we’re going to lay out a plan on what the work would take,” said NASA spokesperson Bruce Buckingham, of the agency’s Kennedy Space Center (KSC) where the meeting is underway, adding that it’s still far from final whether additional work will be required at the shuttle’s launch pad.

The four bolts latching Atlantis’ antenna dish in place are shorter than those stipulated in engineering specifications, but have flown on all 26 of the shuttle’s spaceflights. Engineers have expressed some concern that the bolts could shake loose during launch, which could send the antenna plunging down the length of Atlantis’ 60-foot (18-meter) payload bay and cause serious damage to the orbiter.

“If we did decide to go do the work, it could in all likelihood not affect our launch date,” Buckingham said.

Atlantis is slated to launch from KSC’s Pad 39B site no earlier than 4:30 p.m. EDT (1030 GMT) on Aug. 27 to begin an 11-day mission to the International Space Station (ISS).

Its STS-115 mission, commanded by veteran shuttle astronaut Brent Jett, will deliver a new solar array and pair of truss segments to the orbital laboratory.

But first Atlantis must pass muster before teams of safety engineers and top shuttle officials during a standard pre-launch meeting known as the Flight Readiness Review
