Reaching another star system within a human timescale requires traveling at a sizeable
fraction of the speed of light. To achieve this, the Breakthrough Starshot program proposes a …

Precision wavefront control on future segmented-aperture space telescopes presents
significant challenges, particularly in the context of high-contrast exoplanet direct imaging …

ATTITUDE reorientation is a process of controlling the attitude of a rigid spacecraft to the
desired orientation. It plays an important role in guaranteeing the success of on-orbit space …

Ground-based observatories' capabilities can be greatly enhanced by working with satellites
in astrostationary orbits. Satellites inertially aligned with ground-based observatories can …

The mirrors of astronomical interferometers need to be aligned within a fraction of a
wavelength relative to one another. This would be especially challenging for optical …

The challenges of high contrast imaging (HCI) for detecting exoplanets for both ground and
space applications can be met with extreme adaptive optics (ExAO), a high-order adaptive …

为解决地球遥感观测和星载激光雷达探测等领域对空间光学系统尺寸小型化,

Improving space situational awareness (SSA) remains one of the Department of Defense's
(DoD) top priorities. Current research has shown that the modeling of geosynchronous orbit …

Large segmented aperture ground and space based telescopes are undergoing
development to enable direct imaging of extrasolar planets. The ground-based GMT (Giant …

We present all aspects of the development of a ½U laser guide star CubeSat payload. The
payload, AMS Beacon, was integrated into the Agile Microsat (AMS) 6U platform developed …
