The Space Shuttle Atlantis is looking good in terms of making its scheduled rendezvous with the International Space Station (ISS). The two craft will dock this afternoon (Sunday) to exchange a crew member and deliver and install a new power module with two solar panel "wings" on the station. Three spacewalks are planned as part of the week-long construction task.
There is some concern over a 10-cm "flap" where the corner of one of the heat-shielding fabric blankets near the Shuttle's tail has come loose. At least two shuttles have safely re-entered with similar damage, but NASA is evaluating the problem. If mission managers decide a repair is needed, the astronauts have procedures and tools to either tack down the fabric or put a cover of heat-shielding material over the spot.
