Shuttle managers on Thursday designate a June 28 target launch date for the “final” flight of  the program. A crew of four would launch supplies to the station during an 11-day mission that could be extended. Station managers would like the mission to fly closer to the Sept. 30 end of the 2011 fiscal year. http://space.flatoday.net/2011/01/atlantis-officially-designated-final.html

4. From the Associated Press via the Los Angeles Times and others: In Washington, conservative lawmakers propose even greater spending cuts than those pledged by Republicans in the fall Congressional campaign. The Republican Study Committee proposes $175 billion in cuts, taking the federal government back to 2006 spending levels, rather than the campaign pledge of 2008 levels. That could mean a pay freeze for federal workers and a reduction of 15 percent in the federal workforce through attrition. Some lawmakers hope to spare agencies like NASA, the FBI and the Bureau of Indian Affairs. http://www.latimes.com/news/nationworld/nation/wire/sns-bc-apfn-us–congress-spending,0,3400196.story

Astronaut Mark Kelly, Giffords husband and commander of NASA’s final scheduled shuttle mission, says the transfer will permit him to both be with his wife and return to work. Giffords is recovering from a gunshot wound received at a Jan. 8 political rally. Kelly and NASA have yet to decide whether he can lead Endeavour’s April 19 mission.
