James Webb Space Telescope
Proposal Solicitation, Planning, and Scheduling

The opportunity to propose for Webb observations will be open to the international astronomical community. We anticipate that the first Call for Proposals will be issued approximately 1 year before launch. The first year of science observations will include a minimum of 25% (maximum of 50%) Guaranteed Time Observations. The GTO portion will ramp down in years 2 and 3.

As with Hubble, Chandra, and Spitzer, proposals requesting Webb resources will have to go through the steps of proposal preparation, proposal selection, and observing plan scheduling.

Once scheduling is completed, the program will become part of the Flight Operations.
