Amateur astronomers boost ESA's asteroid hunt
A partnership with the UK鈥檚 Faulkes Telescope Project promises to boost the Agency鈥檚 space hazards research while helping students to discover potentially dangerous space rocks.
ESA鈥檚 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 鈥� known as 鈥榥ear-Earth objects鈥�, or NEOs, since they cross Earth鈥檚 orbit 鈥� are a particular problem.
Any attempt to survey and catalogue hazardous asteroids faces a number of difficulties. They鈥檙e often jet black or at least very dark, they can approach rather too close before anyone sees them, and they鈥檙e often spotted only once and then disappear before the discovery can be confirmed.
Crowdsourcing the astronomy community
So ESA is turning to amateur astronomers to 鈥榗rowdsource鈥� observations as part of Europe鈥檚 contribution to the global asteroid hunt. These efforts will add to the follow-up observations already done at ESA鈥檚 own telescope on Tenerife in the Canary Islands.
This month, the UK鈥檚 Faulkes Telescope Project will become the latest team to formally support the SSA programme. Spain鈥檚 La Sagra Sky Survey, operated by the Observatorio Astronomico de Mallorca, began helping SSA earlier this year.
Sharing expertise and observing time
鈥淭he wider astronomy community offers a wealth of expertise and enthusiasm, and they have the time and patience to verify new sightings; this helps tremendously,鈥� says Detlef Koschny, Head of NEO activity at ESA鈥檚 SSA program office.
鈥淚n return, we share observing time at ESA鈥檚 own Optical Ground Station in Tenerife and provide advice, support and professional validation. We鈥檒l assist them in any way we can.鈥�
The Faulkes Telescope Project runs both educational and research programs, based at the University of Glamorgan in the UK.
Public education and outreach
The project has a strong record in public education and science outreach, and is a partner of the US-based Las Cumbres Observatory Global Telescope network, which owns and operates two telescopes. Faulkes supports hundreds of schools across Europe.
鈥淥ur new cooperation with ESA is a great opportunity. Use of the 2 m-diameter telescopes in Hawaii and Siding Spring, Australia, will greatly enhance asteroid-spotting for the SSA programme, enabling fainter object detection and tracking from a global telescope network,鈥� says Nick Howes, Pro-Am Programme Manager at the Faulkes Telescope.
鈥淔or European students, collaborating on exciting ESA activities and possibly detecting new NEOs is very appealing, as it鈥檚 engagement with one of the world鈥檚 great space agencies doing critical scientific work.鈥�
ESA鈥檚 SSA programme is developing services and infrastructure to enable Europe to observe NEOs, predict their orbits, produce impact warnings and be involved in possible mitigation measures and civil response.
It will also provide services to monitor man-made debris objects in orbit that can pose hazards to satellites and to monitor the effects of space weather phenomena on space and ground assets.
