1 lip 2021 · Start misji Near-Earth Object Surveyor, czyli NEO Surveyor, jest zaplanowany na pierwszą połowę 2026 r. „NEO Surveyor jest zaprojektowany tak, aby odkryć 90 proc. asteroid o wielkości 140 metrów lub większych w ciągu dekady od uruchomienia” – zapowiada Mike Kelley z NASA w oficjalnym oświadczeniu.
Citizen Science. The Near-Earth Object (NEO) Observations Program is a key element of NASA’s Planetary Defense Program, funding efforts to search for undiscovered NEOs using observatories around the world, calculate and refine NEO orbits, determine NEO physical properties and composition, and study NEO deflection and mitigation technologies.
The NEOCC is ESA's centre for computing asteroid and comet orbits and their probabilities of Earth impact.
