The Large UV/Optical/IR Surveyor (LUVOIR) is a concept for a highly capable, multi-wavelength observatory with ambitious science goals. This mission would enable a great leap forward in a broad range of astrophysics, from the epoch of reionization, through galaxy formation and evolution, to star and planet formation. LUVOIR also has the major goal of characterizing a wide range of exoplanets, including those that might be habitable—or even inhabited.
LUVOIR is one of four Decadal Survey Mission Concept Studies initiated in January 2016. The study will extend over three years and be will executed by the Goddard Space Flight Center, under the leadership of a Science and Technology Definition Team (STDT) drawn from the community.

The Origins Space Telescope (OST) is one of the four Decadal Survey Mission Concept Studies initiated in January 2016. The study is being executed at Goddard Space Flight Center, under the leadership of a community-based Science and Technology Definition Team.
The OST team is developing two concepts for a Far-Infrared Surveyor mission, as described in the Astrophysics Roadmap. It will address a wide variety of topics that can be studied at Far-IR wavelengths, ranging from Exoplanets to planetary system formation to star-formation on scales both large and small to the rise of metals in the Universe over cosmic time.

The Habitable Exoplanet Imaging Mission (HabEx) is a concept for a mission to directly image planetary systems around Sun-like stars. HabEx will be sensitive to all types of planets; however, its main goal is, for the first time, to directly image Earth-like exoplanets and characterize their atmospheric content. By measuring the spectra of these planets, HabEx will search for signatures of habitability such as water, and be sensitive to gases in the atmosphere possibility indicative of biological activity, such as oxygen or ozone. In addition to the search for life on Earth-like exoplanets, HabEx will enable a broad range of general astrophysics, from studying the earliest epochs of the history of the Universe, to understanding the life cycle and deaths of the most massive stars, which ultimately supply the elements that are needed to support life as we know it.

The Lynx mission concept seeks to provide unprecedented X-ray vision into the universe. Lynx will directly observe the dawn of supermassive black holes, reveal the drivers of galaxy formation, trace stellar activity (including effects on planet habitability), and transform our knowledge of endpoints of stellar evolution. Expanding on the legacy of the Chandra X-ray Observatory, Lynx’s design will include excellent angular resolution, high throughout, a large field-of-view, and high spectral resolution for both point-like and extended sources.

The Hubble Space Telescope is in a decaying orbit that will cause an uncontrolled re-entry in around 2025. To prevent the hazards created by such an event, the Cosmic Origins Program Office has undertaken a study of a mission to dispose of the great observatory, either by controlled re-entry or placement into a long life orbit.
