CHANDRA ELECTRONIC ANNOUNCEMENT NUMBER 28


One announcement:

1.  Joint Chandra/Hubble/Spitzer Programs


----------------------------------------------------------------

Item 1. Joint Chandra/Hubble/Spitzer Programs 
=============================================


Dear Colleagues,

With three of NASA's Great Observatories operating, there is a very 
special window of opportunity for observing programs requiring more than 
one of these telescopes. Chandra, Hubble and Spitzer offer joint time 
allocation to observe on two or three of
the Great Observatories with a single proposal, evaluated by
a single Time Allocation Committee (TAC).  In addition each of the
Great Observatories also offers joint time programs with major
ground-based optical/IR and radio observatories.

With the finite cryogenic lifetime of Spitzer and the aging
of the other Great Observatories, this window of opportunity
is very short (perhaps 3 more years for the Spitzer component).
All members of the science community are encouraged to capitalize on 
this unique opportunity for projects which require observations from
multiple telescopes and fit within the time allocated for joint
projects.

The joint time allocation categories were designed to ensure that the 
best projects that require observing time on more than one
of NASA's Great Observatories (or with one space observatory
and a ground-based observatory) can be selected in a timely manner
and receive the required time without going through the process
of submitting proposals to multiple TACs.

The details of the program can be found in the Call for Proposals
released by each of the Chandra, Hubble and Spitzer Observatories. See:
