And it commemorates its tenth birthday this week.When the Chelyabinsk asteroid struck the skies over Russias Ural area in February 2013, it highlighted mankinds fragility.With a mass of around 12,000 tonnes and a size of 19 m, the Chelyabinsk asteroid was the second-largest asteroid to strike Earth in the last century. Credit: Sandia LabsBy an unusual twist of fate, the Chelyabinsk asteroid struck on the same day that the United Nations Committee on Peaceful Uses of Outer Space Working Group on Near-Earth Objects fulfilled in Vienna to finalize a suggestion to the UN on how to protect Earth from possible asteroid impacts.At this meeting, Earths professionals laid the structures for the development of two worldwide bodies that would make it possible for a really international reaction to the danger of an asteroid strike: the International Asteroid Warning Network (IAWN) and the Space Mission Planning Advisory Group (SMPAG; pronounced same page). What would occur if ESA and area companies around the world discovered an asteroid likely to impact our planet?As a member of the International Asteroid Warning Network, ESA and other agencies work together to generate warnings in case of a potential asteroid impact, passing validated realities to nationwide emergency action agencies.Depending on the size of the asteroid, the opportunity of it striking Earth and how much advance caution is supplied, a range of choices are available.In space, options consist of reconnaisance missions to gather more infomation and deflection objectives to push the asteroid onto a various– and safe– path.Preparations on the ground involve possible evacuations and catastrophe reaction management.Credit: ESAKeeping Humankind on the Same PageSMPAG and IAWN are now commemorating their tenth anniversaries, with the first SMPAG conference taking location on 6-7 February 2014 and the first IAWN conference taking place in January of the same year.IAWN is collaborated by NASA: it is a worldwide cooperation of asteroid observers, modelers, and analysts. It will come closer to our world than the ring of telecoms and weather forecasting satellites in geostationary orbit.In the worlds first test of asteroid deflection, Hera will perform a comprehensive post-impact survey of the target asteroid, Dimorphos– the orbiting Moonlet in a binary asteroid system known as Didymos.
