A novel composite material ablative TPS for planetary vehicles that can survive a dual heating exposure is proposed. NextGen's TPS concept is a bi-layer functional composite. The top ablative layer is a two polymer composite layer formed in a conformal shape by infiltrating ablative polymer in a Si based polymeric foam with controlled pore size distribution. This layer is for the aerocapture ...

The proposed project aims to develop a board level solution for the NASArsquo;s microwave correlation radiometers required for Earth sensing applications. Spaceborne instrumentation requires minimized size, weight and power (SWaP). Present solutions rely on analog signal processing, thus are bulky, power hungry and cannot be reprogrammed. Analog filter parameters tend to be unstable over temperatu ...

The Problem: There is no GPS (absolute positioning) on Mars ndash; nor on any other extraterrestrial body of scientific interest. All existing navigation solutions for rover/robotic platforms provide only relative navigation capabilities, which drift off over time and are not sufficiently accurate for many scientific missions of interest.nbsp; Future autonomous robotics missions will require an ab ...

NASA is developing algorithms and methodologies for efficient air-traffic management (ATM). Several researchers have adopted an optimization framework for solving problems such as flight scheduling, route assignment, flight rerouting, nationwide traffic flow management and dynamic airspace configuration. Computational complexity of these problems have led investigators to conclude that in many ins ...

We propose to design a compact, high-precision, single-axis accelerometer based on atom interferometry that is applicable to operation in space environments. Our design will emphasize reliable operation and minimization of the acceleration noise floor, bias drifts and scale factor instability. Laser system reliability will be a major consideration in the design. The sensor design will be capable o ...

We propose to build a compact, high-precision single-axis accelerometer based on atom interferometry that is applicable to operation in space environments. Based on our successful Phase I design, the proposed accelerometer emphasizes reliable operation and exceptional acceleration sensitivity. It incorporates several innovative features that make it appropriate for a variety of space-based and ter ...
