The series of briefings will focus on shuttle Endeavour's STS-130 mission to deliver the final module of the U.S. portion of the International Space Station. The briefings have been rescheduled to allow more analysis of engineering data from the test of high-pressure ammonia jumper hose assemblies that failed during a prelaunch test last week. The results will determine if there will be any impact to the shuttle mission. Teams continue to work toward a target launch of Feb. 7.

Previously submitted requests from reporters for credentials to attend the briefings, or to participate in round-robin interviews with an STS-130 astronaut, will be adjusted for the new date and do not need to be resubmitted. Reporters who have not requested credentials and are planning to attend the briefings in Houston must contact the Johnson newsroom at 281-483-5111 by 5 p.m. CST, on Jan. 21.

Endeavour's six astronauts will be available for interviews at Johnson. New requests to reserve an interview slot should be submitted to Gayle Frere at 281-483-8645 by Jan. 21.

8 a.m. - STS-130 Video B-Roll feed
9 a.m. - STS-130 Mission Overview Briefing
10:30 a.m. - STS-130 Spacewalk Overview Briefing
