Cubesat illustrates Earth science device

WASHINGTON - A Cubesat initiated earlier in the current year has adequately tested an edition of an instrument that will hover on a more significant NASA operation in development.  

The Hyper-Angular Rainbow Polarimeter (HARP) Cubesat was installed in February from the International Space Station (ISS) following its delivery to the station on a Cygnus cargo space ship. The Cubesat ferries imaging Polarimeter was built to gauge the properties of aerosol and cloud particles in Earth’s atmosphere.  

Space Dynamics Lab (SDL) of Utah State University manages the three-unit Cubesat and also designed the spacecraft. The payload was created and is run by the University of Maryland B Baltimore County (UMBC). The payload accomplished “first flight” in April and took their original pictures in May. 

Tim Nelson, the program director for HARP at SDL, stated that the spaceship displays that CubeSats can offer valuable data in Earth sciences. Tim confirmed in a statement that the application of Earth observation technology-based in space has, in the past, been the domain of big satellites. He added that HARP helps confirm that miniaturized antennas on tiny satellites can generate a high degree of reliability at a portion of the time and cost it takes to construct bigger satellites. 

The instrument’s utility derives from its capability to gauge the size allotment of cloud droplets that can give information on the ice and water clouds properties. That could, in turn, enhance aerosol processes modeling and assist in reducing qualms in climate modeling.

HARP is a forerunner for a related instrument dubbed, HARP2, being developed by UMBC for NASA’s Plankton, Cloud, Aerosol, ocean Ecosystems mission. HARP2 is set to feature enhanced resolution and antenna performance and will be in a position to offer world coverage every two days from the sun-synchronous orbit of PACE. 

PACE has been the talk of frequent attempts at cancellation in the budget request of the administration, comprising in the 2021 fiscal year budget proposal earlier in the current year. Nonetheless, Congress has declined those proposals and decided to fund the development of PACE. The spaceship is set to initiate on a SpaceX Falcon 9 rocket in late 2022. 

Tiny satellites such as CubeSats play a significant role in technology demonstration, exploration, scientific research, and educational research at NASA. These small satellites offer a cheap platform for NASA operations, comprising planetary discovery, Earth observations, and essential space and Earth science.
