About the challenge

The Orbital Clarity Challenge is the sixth in the NASA TechLeap Prize series. A collaborative effort between NASA’s Heliophysics Division, Flight Opportunities program, and Center of Excellence for Collaborative Innovation, the challenge seeks to advance orbital drag measurement for safer, more predictable satellite flight paths. NASA invites applicants to propose low-cost, scalable approaches that enable proliferated measurements of density, pressure, or drag in low Earth orbit. Up to four winners will each receive up to $500,000 to develop a flight-ready solution across three prize phases. In addition, NASA intends to provide an opportunity for the winning team(s) to demonstrate their solution in orbit, at no cost.

Timeline

Across three phases, applicants will move from concept to flight-ready solution over 12 months. The timeline for this challenge is intentionally rapid, with the goal of increasing the pace of space.
