One small step for mankind , a giant leap for Rozetta (UPDATE)

Philae snapped this photo after it seperated from the

If you were following mainstream media sources , the Rozetta orbiter mission to the comet 67P/Churyumov-Gerasimenko is probably not new to you . The European Space Agency (ESA's) mission to the 4km wide comet that is travelling at 66,000 km/h marks the first time man (or in this case a unmanned vehicle) has attempted to land on a comet . The 67P/Churyumov-Gerasimenko comet is 6.4 Billion Kilometers away and it took Rozetta and its probe - Philae 10 years (launched in 2004) to complete the journey . Rozetta has successfully launched its probe - Philae and once it does reach the surface of the comet (afer a 7 hour journey, which will conclude at 11.03 AM E/T) , the probes built in ice screws and harpoon will tether it to the surface as the probes primary active thrust system that was supposed to keep the probe in place failed to launch . The probe , which weighs about 100kg's is packed with 21 different instruments that will gather important scientific data about a comets composition and age will work in tandem with the Rozetta "mothership" which will relay data back to Earth in a 28 minute gap.

UPDATE-

Philae lands!!!! but signs of trouble were not over for ESA ground control as only 3 of the harpoons managed to get a perfect lock  and so it had a rough landing .The awkward position has caused problems for Philae as the sun only appears for 3 hours every 24 hours which means our little explorer will have to dig using auxillary power . 






Philae has managed to record "Sounds of a comet" which are said to be sounds created by Oscillations around the rocks magnetic field , the sound is said to be 40-50 millihertz , the sound you hear in this soundcloud  track (which sounds like some Alien Dubstep btw)  is said to be amplified 100k times in order to be audible for humans .
