The seven astronauts returning from ISS on board space shuttle Discovery completed final preparations Tuesday for their return home with landing planned for the first of two opportunities to the Kennedy Space Center, Fla., at 1:02 p.m. EST Wednesday, NASA said.

Weather conditions appeared favorable for the scheduled landing of the Space Shuttle Discovery on Wednesday, NASA officials added.

It seems like weather would not be a problem after a cold front passes through late Tuesday.

On a visit to the International Space Station that began October 25, the Discovery crew conducted four spacewalks, installing a new Italian-made module and moving a solar panel. The ISS crew will now move the Harmony module to its permanent position to make way for further expansion of the station.

In preparation for the return home, the crew tested flight control systems and thruster jets, stowed equipment and installed a special reclining seat for Clay Anderson, who is returning after more than five months on board the International Space Station.

Wednesday morning, Entry Team Flight Director Bryan Lunney and his team will oversee Discovery’s reentry and landing with the deorbit burn set for 11:59 a.m. The 1 minute, 58 second burn will slow Discovery by 148 miles per hour (217 feet per second) for the reentry.

NASA is also ready for a second landing opportunity and Lunney will consider Florida only for Wednesday’s landing attempts.
