HST Joint Programs

Hubble has a long history of encouraging and facilitating multi-wavelength science through its joint observing programs. Since Cycle 9 of HST in the year 2000, scientists thinking about multi-wavelength projects with Hubble have been able to propose for an expanding list of facilities that now spans the Chandra X-ray Observatory, NOAO telescopes, Spitzer, XMM-Newton, and NRAO telescopes. This science is often more than the sum of its parts, and enables time-domain and synergistic astrophysics studies not possible with the traditional double-jeopardy approach to arranging observing campaigns. Almost 4000 HST orbits in about 350 joint observing programs have been awarded since the inception of the joint observing program framework, equivalent to more than a year's worth of Hubble observations.

The links below give bibliographical information related to each accepted program. The planned orbit counts may not be completely accurate especially for multi-cycle programs.
