Kgnu - How On Earth

Rosetta [feature starts at 5:27] The Rosetta Space Mission has been in flight for ever 12 years and will be ending with a dramatic crash this Friday morning around 10:40 UT (4:40 am Mountain time) - it’s an event that will be watched and talked about by people around the world. Rosetta is run by the European Space Agency, with contributions from NASA. The mission’s goals have been to study a comet to learn not only about how comets work, but what comets can tell us about the origins of the solar system, and perhaps connections to water and life. Rosetta was the first spacecraft to orbit and escort a comet as the comet approached and flew past the Sun, and Rosetta also carried a smaller spacecraft, named Philae, that performed the first landing on a comet. The Rosetta mission has a very strong Colorado connection, since one of the instruments - an ultraviolet spectrograph called “Alice” - was operated from the offices of Southwest Research Institute right here in Boulder.We have three members of the Rosetta
