NASA's Earth Science Technology Office (ESTO) has achieved a new feat as its dual-frequency science antenna is now operational in low-Earth orbit aboard MuSat2, a commercial remote-sensing satellite owned by aerospace pioneer Muon Space. This cutting-edge technology, a descendant of the Next Generation GNSS Bistatic Radar Instrument (NGRx), holds the potential to revolutionize the precision of ocean surface wind speed measurement, a crucial element in predicting hurricane intensity.
Jonathan Dyer, CEO of Muon Space, emphasizes the ambition to enhance this technology's capacity both in its functioning and applications. MuSat2 operates by capturing signals emitted by navigation satellites, which are scattered by the features of Earth's surface and redirected back into space. The data points garnered from how these signals are altered through interaction with the Earth's surface will supply meteorologists with vital information to understand severe weather phenomena.
Chris Ruf, the mind behind the NGRx system and director of the University of Michigan Space Institute, explains the mainstream application of this technology using ubiquitous GPS signals albeit an upgraded manner as compared to the established system. Ruf is also recognized for creating the foundation of the CYGNSS sensors, which, since 2016, has been indispensable in hurricane forecasting.
In contrast to CYGNSS's restricted capabilities, MuSat2's science antenna harnesses measurements from a broader array of satellites including those from the European Space Agency's Galileo, providing denser data capture as it traverses the globe. Additionally, the antenna's capability to collect co-polar radar signals, beyond the cross-polar captures of its predecessor, introduces the possibility of improved insights into soil moisture, sea ice, and vegetation conditions.
From a commercial standpoint, this development marks a milestone for Muon Space. Dallas Masters, Muon’s Vice President, points out that the ripe technology from NASA lowered the barriers to launching a commercial remote sensing satellite, enabling early mission planning. This resonates with Dyer's acknowledgment of the advantage bestowed by NASA's proof of concept, which grants assurance in the technology's reliability and effectiveness.
The antenna's advanced data collection is set to streamline the conversion of raw data into compelling scientific insights and advance the accuracy of forecast models. According to oceanographer Lew Gramer, Associate Scientist at the Cooperative Institute For Marine And Atmospheric Studies and NOAA’s Hurricane Research Division, refined information is priceless for predicting and understanding weather events.
The collaboration between NASA's Earth Science Technology Office and Muon Space truly exemplifies the symbiosis between public sector research endeavors and private sector innovation, paving the way for advancements in environmental science and weather forecasting.
