Launch of Europe's solar probe postponed to Oct 2018
Paris (AFP) April 14, 2015
Solar Orbiter, a probe designed to observe the Sun in unprecedented detail, will be launched in October 2018, around 15 months later than planned, the European Space Agency (ESA) said Tuesday. Postponement was decided "to ensure that all of the spacecraft's scientific goals will be achieved, with all the system's components adequately tested," it quoted Solar Orbiter's project manager Philippe Kletzkine as saying. Solar Orbiter is designed to carry 10 instruments to within 43 million kilometres ... read more
