AI Insight
NASA has launched the Orbital Clarity Challenge, the sixth NASA TechLeap Prize, seeking innovative low-cost methods to measure thermospheric density, pressure, or drag in low Earth orbit. The competition addresses the need to better understand how solar activity causes atmospheric expansion and creates orbital drag on satellites. The challenge will advance up to four winning concepts through three phases over 12 months, culminating in free test flights provided by NASA.
Why it matters
Improved measurement of atmospheric density in low Earth orbit is critical for predicting satellite drag and preventing orbital debris collisions. Affordable, scalable sensors that can be deployed across commercial satellite fleets would significantly enhance space weather monitoring capabilities and protect space infrastructure.

The Orbital Clarity Challenge — the sixth in the NASA TechLeap Prize series — is a collaborative effort between NASA’s Heliophysics Division, Flight Opportunities program, and Center of Excellence for Collaborative Innovation. The Heliophysics Division studies space weather, including how it heats and expands Earth’s outer atmosphere during intense solar activity, creating orbital drag through atmospheric density changes. The challenge calls for low-cost methods of measuring thermospheric density, pressure, or drag in low Earth orbit. NASA is seeking approaches that are inexpensive and scalable enough to be produced in quantity and flown as hosted payloads across the commercial fleet. The challenge will unfold across three phases, advancing up to four winners’ concepts to a flight-ready solution within 12 months. At the conclusion of the challenge, NASA intends to offer each winning team a test flight at no cost.
Award: Up to four winners may receive up to $500,000 in prizes across three phases
Challenge Open Date: August 19, 2026
Phase 1 Registration Close Date: October 28, 2026
Phase 1 Submission Close: November 11, 2026
