R-MXAS is a revolutionary aerospace architecture for realizing a synthetic aperture imaging radiometer (SAIR) with dramatically lower size, weight and power (SWaP) than existing state-of-the-art (SOTA) methods. The space-based component of R-MXAS is a single platform comprising a 1-D sparse/decimated antenna array on a rigid tether (deployed parallel to the horizon) and one or more additional tethered antennas that rotate in a plane orthogonal to the 1-D array.

The processing that correlates the data from these antenna systems and performs image reconstruction has both space-based and ground-based components. The processing exploits the interferometric baselines formed between the rotating tethered antenna at radius R and each of the antennas of the 1-D array on the rigid tether.

NASA Invests in Shapeshifters, Biobots & Other Visionary Technology


WASHINGTON, DC (NASA PR) — NASA is investing in technology concepts that include¬†meteoroid impact detection, space telescope swarms, and small orbital debris mapping technologies that may one day be used for future space exploration missions.

The agency selected 25 early-stage technology proposals that have the potential to transform future human and robotic exploration missions, introduce new exploration capabilities, and significantly improve current approaches to building and operating aerospace systems.
