Meanwhile, in addition to sending back some excellent pictures of the comet 67P, Rosetta has also completed analysis of the gases that the comet has been releasing as it approaches the Sun. Rosetta has found methane, methonal, Carbon di-oxide and water in these gases, all constituents that would be required to make amino acids, the building blocks of proteins in our body. It will be up to Philae to check amino acids in their native forms are actually present on this comet. While Rosetta has found hydrogen and oxygen separately, water, is strangely missing from the surface of the comet.
For now, Rosetta is about 30 km away from the comet and is making its way to get as close to 1 km to the comet, before she let’s Philae go. This is expected to happen mid- November, so keep following our blog to get these timely updates.
And if you cannot wait to see what will happen in November, here is an excellent 3D model of the Rosetta mission that marks its progress so far and its milestones ahead. Not only is it a great looking model, its interactive too! So, give it a try and tell us how you find it. The creators of this visualization at INOVE will like that too! Thank you, Michal Saldon at INOVE for bringing this to our notice and if you like this, there is another visualization of Comet Siding Spring which will have a close encounter with Mars this October.
