This review paper addresses topics of fabrication, testing, alignment, and as-built
performance of reflective space optics for the next generation of telescopes across the x-ray …

A direct image of an exoplanet system is a snapshot of the planets and disk around a central
star. We can estimate the orbit of a planet from a time series of images, and we can estimate …

Exo-S is a direct imaging space-based mission to discover and characterize exoplanets.
With its modest size, Exo-S bridges the gap between census missions like Kepler and a …

We present a new method to achieve high-contrast images using segmented and/or on-axis
telescopes. Our approach relies on using two sequential deformable mirrors (DMs) to …

We summarize the current best polychromatic (∼ 10% to 20% bandwidth) contrast
performance demonstrated in the laboratory by different starlight suppression approaches …

This special section is dedicated to starshades: science, engineering, technology, and
programmatics. Our reasons for organizing this special section are several fold. First as a …

A deployable structure serves an important function in small satellites as their performance
is improved steadily. Larger deployable solar array paddles are expected as the satellite …

This paper presents a new formation design that enables deployment of large distributed
telescopes aligned with inertial targets in Earth orbit. To minimize propellant consumption …

As part of NASA's mission to explore habitable planets orbiting nearby stars, this article
explores the detection and characterization capabilities of a 4 m space telescope plus 50 m …

The orbital light curve of a terrestrial exoplanet will likely contain valuable information about
the surface and atmospheric features of the planet, both in its overall shape and hourly …
