Topic H3.01 captures the need for robust, multipurpose deployable structures with high packing efficiencies for next generation orbital habitats. Multiple launch and payload providers have expressed interest in repurposing pressure vessels as on-orbit habitats and require outfitting for secondary structure, floors and dividers, ECLS ducting, thermal control accommodation, radiation shielding, wiri ...

DeepAnalytX, Inc. proposes to investigate a new approach to perform real-time, closed-loop optimal and robust rendezvous guidance in space environments comprising a potentially large number of spacecraft. More specifically, we propose to research and develop an advanced guidance system that is able to learn and track a fuel-efficient, collision-avoidance velocity vector field thus enabling safe, r ...

Atmospheric methane is the second most important anthropogenic greenhouse gas. The overtone lines of methane at 1.65 micron are well suited for remote sensing of atmospheric methane in the Earth?s atmosphere. NASA have already demonstrated ground-based and airborne methane detection using Optical Parametric Amplifiers at 1651 nm using a laser with a narrow linewidth. In this setup a single frequen ...

We propose to demonstrate and build a 1.572 micron single frequency high pulse energy and high peak power fiber laser by using an innovative Er-doped gain fiber with large core diameter and high gain per unit length. 1.572 micron single frequency high energy and high peak power fiber laser is needed for accurately measuring column CO2 concentrations . In Phase I, we will design and fabricate the l ...

TIPD proposed to build a stable, robust, rugged, compact, fiber coupled gas reference cell (GRC) with tens of meters of interaction length that is required in atmospheric constituent and trace gas analysis sensors as well as LIDAR instruments in the near and shortwave infrared supporting NASA's future planetary science missions. Specifically, this proposal addresses the need for a water vapor refe ...

We propose an innovative, low coherence probe for rapid measurement of free-form optical surfaces based on a novel method of spectrally controlled interferometry. The key innovations are the use of a new interferometric modality and a novel non-contact optical probe that together measure high surface slope acceptance angles to nanometer sensitivity. When the probe is integrated with a precision mo ...
