We describe how environmental context can help determine whether oxygen (O2) detected
in extrasolar planetary observations is more likely to have a biological source. Here we …

Oxygenic photosynthesis is Earth's dominant metabolism, having evolved to harvest the
largest expected energy source at the surface of most terrestrial habitable zone planets …

Abstract Space sails are a continuum of lightweight, thin, large-area, deployable
technologies which are pushing forward new frontiers in space mobility and exploration …

The Advanced Technology Large Aperture Space Telescope (ATLAST) team identified five
key technology areas to enable candidate architectures for a future large-aperture …

This paper addresses the design, calibration, and utilization of a hardware-in-the loop
optical stimulator for the training and validation of vision-based sensors and algorithms used …

The NASA Astrophysics Division's 30-Year Roadmap prioritized a future large-aperture
space telescope operating in the ultra-violet/optical/infrared wavelength regime. The …

The Advanced Technology Large Aperture Space Telescope (ATLAST) team has identified

The HabEx and LUVOIR mission concepts reported science yields for mission scenarios in
which the instruments must search for potentially habitable planets, determine their orbits …

With the abundance of planets discovered in nearby solar systems, the opportunity to
directly image these planets is of keen interest in the scientific community. A starshade …

The design and scale of a future mission to directly image and characterize potentially Earth-
like planets will be impacted, to some degree, by the expected yield of such planets. Recent …
