First spacewalk delayed, mission extended

Space shuttle Atlantis arrived at the International Space Station Saturday morning after a two-day rendezvous.

Atlantis is delivering the European Space Agency Columbus science laboratory, which will be attached to the station’s Harmony module on Monday now after the decision was made to delay the first spacewalk due to a crew medical issue.

With no impact to the overall mission objectives, the first spacewalk Monday will be conducted by Rex Walheim and Stan Love, who replaces Hans Schlegel, DG1KIH.

The official crew rotation of ESA Astronaut Leopold Eyharts, KE5FNO and Expedition 16 Flight Engineer Dan Tani, KD5DXE originally scheduled for Sunday, was completed at 6:20 p.m. Eyharts is now a member of Expedition 16 and Tani is an STS-122 mission specialist.

STS-122 landing is now planned for 10:14 a.m. Tuesday, Feb. 19, at Kennedy Space Center, Fla.
