Rosetta mission continues
Giorgi Abashidze stashed this in Science
Last week, ESA’s Rosetta spacecraft delivered its Philae lander to the surface of the comet for a dramatic touchdown. The lander’s planned mission ended after about 64 hours when its batteries ran out, but not before it delivered a full set of results that are now being analysed by scientists across Europe.
Comets are time capsules containing primitive material left over from the epoch when our sun and its planets formed. Rosetta will be the first spacecraft to witness at close proximity how a comet changes as it is subjected to the increasing intensity of the sun's radiation. Observations will help scientists learn more about the origin and evolution of our solar system and the role comets may have played in seeding Earth with water, and perhaps even life.
And somewhere I also read that this expedition can make one step toward answering the question - "Are we alone"
Almost certainly we are not alone. We just have to get through the Fermi paradox:
Yes, almost certainly they are out there, and more so it's sad that we can't find them... yet.
But this "yet" may last 500 or 5000 years :)
500 or 5000 years seems small compared with the age of the universe.
But for us it's not a consolation, as in this case we'll never witness it
We will if we think of ourselves as part of humanity.
What about our curiosity? Let's hope discoveries will be made fast enough.
Yes, that's a good reason for us to have a sense of urgency about learning NOW.
