Knowing the air density outside of a spacecraft can have a substantial effect on its angle of descent and ability to hit a specific landing spot. But sensors that can withstand the harsh hypersonic conditions are rare. Aerospace engineering researchers at the University of Illinois at Urbana-Champaign developed an algorithm that can run onboard a vehicle, providing important real-time data to aid in steering the craft, particularly during the crucial entry, descent, and landing stage.
