WASHINGTON โ€” NASA Administrator Charles Bolden will unveil the U.S.space agencyโ€™s spending priorities for 2011 during a Feb. 1 press conference at NASA headquarters here, according to administration officials.

President Barack Obamaโ€™s 2011 budget request is expected to realign NASAโ€™s human spaceflight activities and investments to foster development of commercial systems capable of ferrying astronauts to the international space station.

Bolden is expected to discuss long-awaited details of the presidentโ€™s funding proposal in the morning, followed by a press conference hosted by the White House Office of Science and Technology Policy (OSTP) to rollout Obamaโ€™s research and development priorities โ€” including those that affect NASA goals and funding โ€” for the coming budget year, these sources said. The OSTP press conference is slated for 12:30 p.m. at the American Association for the Advancement of Science here.

In addition to the Monday rollout, Bolden is tentatively slated to host a second news conference Feb. 2 at the National Press Club here, administration officials said.
