The following are closed observing and proposal opportunities for which NExScI has managed the proposal solicitation and selection process.
Each observing semester, NExScI manages the proposal solicitation and selection process for NASA's portion of time on the Keck telescopes.
Click here for a list of proposals that have been awarded NASA Keck observing time since 1996B.
As part of the general call for proposals using NASA Keck time, proposals for Key Science are often included. Key Science proposals address a specific project as described below.
NASA has selected three teams of scientists to begin studying disks of dust around nearby stars starting in February 2008, using the Keck Interferometer. The teams will study stars with known debris disks and look for signs of dust around other stars.
The due date for this solicitation was April 27, 2012 and the team members were announced in early June.
The Astrophysics Division in the Science Mission Directorate at NASA HQ released a Dear Colleague letter to solicit applications from interested individuals for the formation of a study group for the possible scientific use(s) of the ex-NRO telescope assets for advancing the science priorities of the 2010 Decadal Survey New Worlds New Horizons. The selection of the Science Definition Team (SDT) will be done on a fast schedule as detailed in the Notice of Intent; applications are due on September 19, 2012.
In June 2008, SIM and NExScI solicited proposals for SIM Science Studies to enhance the science return from SIM by supporting researchers to conduct concept studies that will lead to the most scientifically productive observations using SIM.
In early 2008, NExScI put out a call for science teams to participate in a near-term project to calculate the ability of SIM/PQ to detect an Earth-mass planet in the habitable zone (HZ) around a nearby star, in the presence of a multiple-planet system as well as instrumental and astrophysical noise. The goal is to perform a double-blind test to understand the ability of the combination of the astrometric SIM/PQ mission, when combined with ground-based radial-velocity (RV) observations, to detect terrestrial-mass exoplanets, and to establish the minimum requirements on this combination.
