April NSA Club Meeting

Kevin Cole, of Harper College, will present information about the European Space Agency's Rosetta Mission to Comet 67P/Churyumov-Gerasimenko, , including the orbiter and lander.  The Rosetta space probe was launched in March, 2004, and arrived at its target ten years later, in August, 2014. Rosetta's lander, named Philae, landed on the comet's surface, but was unable to report the expected volume of data due to its being in shadow and thus unable to maintain battery power in its solar cells. The mission provided information, among other things, on the comet's apparent lack of a magnetic field and the difference between water vapor surrounding the comet and that on Earth. The Rosetta orbiter continued to send data until it was deliberately brought down on to Comet 67P on 30 September, 2016.
