Final system checks on space shuttle Atlantis' aft, or back, section continue on Launch Pad 39A at NASA's Kennedy Space Center today. Technicians also will install several cameras in the shuttle's payload bay.
Workers finished attaching the orbiter midbody umbilical unit from the pad's rotating service structure to the shuttle, and then leak checks were conducted and completed.
Atlantis' cargo, consisting of Express Logistics Carrier 1 and 2, holding about 28,000 pounds of supplies and spare parts for the International Space Station, were moved from the pad's changeout room into the shuttle's payload bay yesterday.
Meanwhile, at NASA's Johnson Space Center in Houston, the six STS-129 astronauts are participating in a final prelaunch meeting with the Mission Control Center's flight director team today, and they’ll also be reviewing final flight data.
