2011 Mission Changes
On April 8th 2011, it was announced in a press release made through NASA's LISA Project Office, that, based on the United States President's Fiscal Year 2012 Budget Request, NASA would likely be unable to continue participating in the LISA project. As a result, the European Space Agency has ended its study of LISA as a partnership at the scale initially proposed in the New Worlds New Horizons decadal survey. Revised mission concepts will be considered in a selection process commencing in February 2012. A decision is expected in April 2012.
A future minor role for NASA in the ESA-led mission has not been ruled out. NASA's Astrophysics Division plans to continue base funding for the LISA study team through FY11, assuming not-larger-than-anticipated cuts from the U.S. Congress.
LISA was originally recommended in the 2010 U.S. National Research Council decadal report on astronomy and astrophysics as one of two large space missions to be implemented by NASA in the upcoming decade. The report recommended that LISA start in 2016, after a successful LISA Pathfinder flight and selection in the ESA Cosmic Vision program, which would have enabled launch in 2025.

Famous quotes containing the word mission:
“... [a] girl one day flared out and told the principal “the only mission opening before a girl in his school was to marry one of those candidates [for the ministry].” He said he didn’t know but it was. And when at last that same girl announced her desire and intention to go to college it was received with about the same incredulity and dismay as if a brass button on one of those candidate’s coats had propounded a new method for squaring the circle or trisecting the arc.”
—Anna Julia Cooper (1859–1964)
