This is not a comet, it's Curiosity on its way to Mars
This, I guarantee, is a view of NASA?s Curiosity rover embarking on its 250 day trip to Mars that you may not have seen before. It?s an extraordinary piece of time-lapse footage taken from Australia not long after launch from Cape Canaveral. It shows a glowing plume from the Centaur stage after a burn over the Indian Ocean ? the Centaur rocket has propelled Curiosity first into a low-Earth orbit and then into an escape trajectory towards Mars. You can also see the sunlit spacecraft itself, a tiny speck gliding across the star-fields of the Milky Way as it heads for interplanetary space.
Bon voyage Curiosity!
