Rocketeers: (Source: SSTL press release) Surrey Satellite Technology Ltd (SSTL) has been selected by the European Space Agency (ESA) for the competitive design phase of CHEOPS science satellite, which will improve mankind’s understanding of exoplanets - planets orbiting distant stars outside our solar system. The contractor selection for the implementation phase is planned by mid-2014 and the launch is scheduled late 2017. The CHaracterising ExOPlanets Satellite (CHEOPS) will finely characterise known exoplanets and their parent stars with an unprecedented accuracy. The satellite will measure the orbit and radius of those exoplanets, enabling the scientists to assess their potential habitability. The mission will also act as a “scout” performing preliminary observations on targets for the future European Extremely Large Telescope and James Webb Space Telescope that will be capable of more detailed analysis. CHEOPS was selected from 25 missions proposed in response to ESA Call for Small Missions in 2012, which was targeting innovative small science missions that offer high value at low cost. CHEOPS is jointly developed by ESA and a consortium of Member States led by Switzerland: The Swiss-built instrument using a Ritchey–Chrétien optical telescope will observe the stars and their orbiting planets, while ESA is responsible for the provision ...
