For Professional Research Using the NASA Allocation for Telescope Observing Time at the W.M. Keck Observatory Proposals for NASA Keck time for observing semester 2012B (August 1, 2012 to January 31, 2013) are due Thursday, March 15, 2012 at 4 pm PDT. This proposal call is now closed. Proposals for observing semester 2013A will be due Sept. 13, 2012.

General Information and Guidelines for applying for NASA Keck Telescope Time - Observing Semester 2012B

• NASA intends the use of the Keck telescopes to be highly strategic in support of on-going missions and/or high priority, long term science goals. Thus NASA Headquarters has opened up the NASA Keck call to a wider range of disciplines spanning from exoplanets and solar system topics to galactic and extragalactic topics. See the link above for more details.
