The United Nations has announced 30 Jun to be International Asteroid Day, and ESA is fasten other space agencies, astronauts, scientists and even stone stars for a 24-hour tellurian telethon.
To symbol this year’s Asteroid Day, ESA will take partial in a singular round-the-clock telethon that will be promote worldwide from Luxembourg, as good as live on a internet, highlighting a hazard from asteroids and other ‘near-Earth objects’ that poise an impact risk.
Hazardous space rocks
In Dec 2016, a United Nations admitted a final day in Jun as International Asteroid Day to lift open recognition about asteroid impact hazards. This date, 30 June, outlines a anniversary of a largest-ever, in complicated times, windy entrance of an meteoroid (thought to be a comet or tiny asteroid), that exploded over a Tunguska shred of Siberia on this day in 1908. With an estimated distance of over 40 m, it ravaged an void area a distance of a vital civil city.
Detritus in a Solar System such as asteroids and other near-Earth objects – basically, anything whose circuit brings it tighten to Earth – impact Earth each day. Most of them are tiny some-more than tiny particles of dirt and afterwards bake adult harmlessly in a atmosphere (have we ever seen a sharpened star?).
However, incomparable ones, such as Tunguska – or a 20 m hole intent that exploded high over Chelyabinsk, Russia, on 15 Feb 2013, with 20–30 times a appetite of a Hiroshima atomic explosve – can bluster tellurian health and property.
“When Tunguska occurred 109 years ago, amiability was not prepared to envision such events,” says Rüdiger Jehn, Co-Manager for NEO activities in ESA’s Space Situational Awareness (SSA) programme.
While a search, circuit determination, prophecy and acknowledgment of melancholy NEOs contain partial of a SSA programme, ESA also sees asteroids as abounding sources for science: ruins of a emergence of a Solar System.
The Agency’s initial asteroid flyby was achieved a hundred years on from a Tunguska airburst when comet-chaser Rosetta imaged asteroid Šteins in 2008, followed by a flypast of asteroid Lutetia dual years later.
The Agency has been formulation destiny asteroid missions – many recently with a Asteroid Impact Mission, that has been revised into a smaller asteroid scouting goal and is now underneath analysis.
Live on Asteroid Day
On 30 June, speakers from ESA will join astrophysicists, astronomers and asteroid experts, including British physicist Prof. Brian Cox, French ESA wanderer and former Head of a European Astronaut Centre Michel Tognini, and specialists during a array of investigate centres as good as NASA and JAXA, in a 24-hour, live and pre-recorded telethon from Luxembourg starting during 03:00 CEST (full orator sum around a Asteroid Day website).

In a Luxembourg studio, Ian Carnelli, manager of ESA’s General Studies Programme who is questioning asteroid goal concepts, will join an consultant panel, while a full 90-minute shred of a day-long telethon will be constructed from ESA’s ESOC goal control centre in Darmstadt, Germany.
In a ESOC segment, 10:30-12:00 CEST, ESA’s NEO experts will horde a array of presentations in front of a live audience, including ‘Armageddon a movie: separating fact from fiction’ and discussions on a need for timely and accurate NEO information.
