NASA's Neowise satellite, designed for planetary defense, tracked hazardous asteroids and comets.
After a decade of service, Neowise fell too low in Earth's orbit, risking its mission.
NASA's Jet Propulsion Lab sent the final command, turning off Neowise's transmitter after 15 years of operation.
An increase in solar activity has heated and expanded Earth's upper atmosphere, affecting Neowise's orbit.
Neowise helped track potentially hazardous asteroids, enhancing our understanding of the universe.
Neowise was a success, laying the foundation for the next generation of planetary defense
Launched in December 2009 as WISE, the satellite originally scanned the entire infrared sky.
The mission evolved from WISE to NEOWISE, focusing on near-Earth objects that could pose a threat.
As Neowise's mission ends, NASA looks forward to future scientific discoveries it helped inspire.
NASA continues its quest for planetary defense, building on the legacy of NEOWISE.
