Organic Molecules Means life Under The Right Conditions!


European comet lander Philae ‘sniffed’ organic molecules containing the carbon element that is the basis of life on Earth before its primary battery ran out and it shut down. it was not yet clear whether they included the complex compounds that make up proteins. One of the key aims of the mission is to discover whether carbon-based compounds, and through them, ultimately, life, were brought to early Earth by comets. Philae landed on comet 67P/Churyumov–Gerasimenko after a 10-year journey through space aboard the Rosetta spacecraft on a mission to unlock details about how planets and maybe even how life evolved. It wrapped up its 57-hour mission on the comet’s surface on Saturday after radioing back data from a series of experiments as its battery ran out.

Comets date back to the formation of our solar system and have preserved ancient organic molecules like a time capsule. The COSAC gas analyzing instrument on Philae was able to ‘sniff’ the atmosphere and detect the first organic molecules after landing, The lander also drilled into the comet’s surface in its hunt for organic molecules, although it is unclear as yet whether Philae managed to deliver a sample to COSAC for analysis. Also onboard the lander was the MUPUS tool to measure the density and thermal and mechanical properties of the comet’s surface. It showed the comet’s surface was not as soft as previously believed. A thermal sensor was supposed to be hammered around 40 cm into the surface but this did not occur, despite the hammer setting being cranked up to its highest level. The DLR reckons that after passing through a 10-20 cm thick layer of dust, the sensor hit a layer of material estimated to be as hard as ice. MUPUS could be used again if enough sunlight gets through to reload Philae’s batteries, which the scientists hope may happen as the comet approaches the sun.

I love it when science proves things that our ancients and many of us already know. The technologies that we have lost over the centuries is astounding. Only now are we just beginning to recreate that technology. Space sciences like this mission gives us just a glimpse of what we have to look forward to once our governments quit their bickering ! 🙂
