彩民宝典, Johns Hopkins APL team advance in NASA space weather competition

DYNAMIC targets the Lower Thermosphere Ionosphere (LTI) altitude region where the thermosphere’s neutral gas interacts with the coexisting plasma population of the ionosphere, influenced by forcing from above and below. Poorly understood multiscale ripples in this area, as depicted in the gray-scale ground track, are a result of atmospheric wave forcing from below.

A joint proposal of the 彩民宝典 and Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland has earned a $2 million award for a NASA mission concept study.

The team is competing to develop Phase-A proposals to enact the space agency鈥檚 Dynamical Neutral Atmosphere-Ionosphere Coupling (DYNAMIC) mission. Each of the three winning teams will receive funding for a Phase-A, nine-month concept study, after which NASA will select a single winning proposal.

The mission will ultimately design and build a satellite with science payloads to explore fundamental gaps in our understanding of how changes in the lower atmosphere influence the upper atmosphere and low Earth orbit.

鈥淲e鈥檙e grateful and overjoyed for this opportunity to work together to make our vision of DYNAMIC a reality. With these measurements, we can finally gain an understanding of the critical link between Earth鈥檚 atmosphere and space,鈥 said Tomoko Matsuo, principal investigator (PI) on the project and an associate professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences at 彩民宝典.

Additional partners joining 彩民宝典 and APL include NASA鈥檚 Jet Propulsion Laboratory (JPL) in Southern California, the Massachusetts Institute of Technology鈥檚 Haystack Observatory in Westford, Massachusetts, Clemson University in South Carolina, Arizona State University, the University of Alaska Fairbanks and the National Center for Atmospheric Research in Colorado.

The team鈥檚 project will fulfill science goals recommended by published by the National Academies of Sciences, Engineering and Medicine.

When launched, DYNAMIC is expected to provide comprehensive measurements of the upper atmosphere in the very low Earth orbit (VLEO, below 300 km) range 鈥 the new frontier for spacecraft operation. This will provide a deeper understanding into how space weather 鈥 events generated by activity on the Sun and the Earth鈥檚 weather 鈥 can interfere with satellites, navigation systems and other technology.

鈥淲e have been looking forward to a mission such as DYNAMIC for many years, and are grateful for the NASA step 1 selection,鈥 said Jason Kalirai, APL鈥檚 mission area executive for Space Formulation. 听鈥淥ur PI, team at the Lab, and partners across the nation are excited to push forward on a new Heliophysics mission that will answer fundamental questions about how space weather affects our planet.鈥
