Key Science Programs

All US community scientists are invited to participate in the development of Key Science Program concepts.

Building foundations laid by the TIO and GMTO Detailed Science Cases (see above), the US ELT Program is working with the US community-at-large to develop concepts for Key Science Programs (KSPs). KSP development will be orchestrated by NOIRLab with advice from the US ELT Program Advisory Committee.

KSPs are envisioned to be open collaborations that gather observers, theorists, and data scientists together to exploit significant investments of TMT and GMT observing time, from tens to hundreds of nights. Some of these collaborations are expected to be international in nature. If well-justified by KSP plans, we envisage that at least 25% of the observing time at each international observatory will be available for the US community.

Developed specifically for presentation to the Decadal Survey and NSF, the KSP concepts now under development may or may not be the actual KSPs executed in the future. Astronomy and astrophysics will continue to evolve rapidly during construction of GMT and TMT, thanks to previous investments in ground– and space-based observatories, such as the NASA Transiting Exoplanet Survey Satellite (TESS), the NASA James Webb Space Telescope (JWST), and the Large Synoptic Survey Telescope (LSST). The actual KSPs to be executed will be selected by peer review at various times (to be determined) before and during GMT and TMT science operations.

Discovery Science Programs

As richly illustrated by the GMTO and TIO Detailed Science Cases (see above), smaller-scale, focused Discovery Science Programs (DSPs) will be an important component of the overall GMT and TMT science programs.
