The area economy is on track to be valued at a trillion dollars by the end of 2030, according to Piyush Mehta, assistant teacher of aerospace and mechanical engineering at West Virginia University. Yet area assets– devices that is positioned in space such as interaction, navigation and weather satellites that serve our society daily– are threatened by space particles.
According to NASA, it is approximated that countless pieces of area debris orbit around Earth. A major part of these debris objects as well as active satellites live in the low Earth orbit region, at altitudes between 200 and 1000 km.
” In low Earth orbit, our ability to secure these area possessions depends on modeling of the aerodynamic forces acting upon the satellites, particularly satellite drag. The drag force acting on a satellite is affected by numerous physical criteria, however, the most uncertain and vital are the drag coefficient and mass density,” Mehta said.
Mehta described that since of the interconnectedness of the two criteria, one of them is held constant, normally the drag coefficient, while the other is investigated. Nevertheless, Mehta stated this causes disparities or mistakes in our understanding of the mass density irregularity in the upper atmosphere or thermosphere.

Recently, Mehta earned the distinguished Faculty Early Career Development, or CAREER, Award from the National Science Foundation to relieve this inconsistency and develop a cutting edge design of thermosphere mass density, which will strengthen scientists comprehending, modeling and forecasting of the upper atmosphere variability.
” We will achieve this by not assuming the drag coefficient to be a constant but getting statistical insights into the physical procedure that drives changes in drag coefficient, particularly the gas-surface interactions that describe the way energy and momentum are exchanged in between the atmosphere and the satellite.” Mehta said. “The CAREER Award will reduce this disparity through an innovative approach that integrates artificial intelligence and statistical evaluation strategies. This is a very specific niche domain with only a handful of research study groups all over the world taking on the problem.”
Mehta leads a collective effort among a few of these groups on satellite drag coefficient modeling under the International Space Weather Action Teams initiative.
Through this highly competitive award, Mehta will get $640,655 in financing over five years to advance this research study task, while likewise establishing strategies to enhance the space science curriculum at WVU.
The Statler College of Engineering and Mineral Resources prepares to establish a brand-new graduate course, space weather condition and area systems, that will be used annual in the Department of Mechanical and Aerospace Engineering. Together with the brand-new course, the College prepares to broaden outreach efforts through hands-on activities for K-12 schools across the state.
” Outreach efforts will establish learning modules and a hands-on construct– a-satellite activity in partnership with the West Virginia Science Public Outreach Team,” Mehta said. “Educational and outreach activities will serve to excite and train the next-generation labor force in area sciences and artificial intelligence.”
The NSFs CAREER program supports junior professors who exhibit the role of teacher-scholars through impressive research study, excellent education and the integration of education and research within the context of their objective organizations.
” Dr. Mehtas cross-cutting research lies at the intersection of atmospheric sciences, space systems engineering and artificial intelligence,” stated Jason Gross, associate teacher and interim chair of aerospace and mechanical engineering, and associate chair for research study at the Statler College. “With the continued quick boost of manmade satellites in low Earth orbit, his work toward improved orbital decay prediction becomes more crucial for the future of area environment sustainability with each passing day. His lab is at the forefront of this crucial field, and we are proud that he is on our professors.”
Mehta stated. “The CAREER Award will minimize this disparity through an ingenious methodology that integrates synthetic intelligence and statistical estimation techniques.” Dr. Mehtas cross-cutting research lies at the intersection of climatic sciences, space systems engineering and maker learning,” stated Jason Gross, associate teacher and interim chair of aerospace and mechanical engineering, and associate chair for research study at the Statler College. “With the continued rapid boost of manmade satellites in low Earth orbit, his work toward improved orbital decay prediction ends up being more crucial for the future of area environment sustainability with each passing day.
