Crowdsourcing Asteroid Detection
Amateur astronomers boost ESA’s asteroid hunt
“A partnership with the UK’s Faulkes Telescope Project promises to boost the Agency’s space hazards research while helping students to discover potentially dangerous space rocks. ESA’s Space Situational Awareness (SSA) programme is keeping watch over space hazards, including disruptive space weather, debris objects in Earth orbit and asteroids that pass close enough to cause concern. The asteroids – known as ‘near-Earth objects’, or NEOs, since they cross Earth’s orbit – are a particular problem. Any attempt to survey and catalogue hazardous asteroids faces a number of difficulties. They’re often jet black or at least very dark, they can approach rather too close before anyone sees them, and they’re often spotted only once and then disappear before the discovery can be confirmed.”
