Today may be the most pressing moment for scientists at the European Space Agency as they make final preparations for a groundbreaking comet landing.
After traveling six billion kilometers since it was sent into space 10 years ago‚ the agency's 100-kilogram lander Philae will finally be separated from its mothership Rosetta and sent to the surface of a comet.
The chaser became the first ever spacecraft to catch up with a comet in August and has been orbiting the comet‚ called Churyumov-Gerasimenko‚ for the past three months.
If the landing is successful‚ the probe will accompany the comet on its trip around the sun with the aim of finding answers about the solar system and the origins of life.
However‚ scientists say it's too soon to pop the champagne as the flying and landing the probe is a very complicated process.
The mission leader at the Operations Center hopes the probe -- if everything goes to plan -- will help scientists learn more about the composition of comets.

"Of course we fly Rosetta to learn everything about comets. () for example what are they made of? What kind of water is on the comets? Is it the same type of water that we find on earth?"
It will take Philae about seven hours from the moment its released from Rosetta to cover the roughly 20 kilometers to land on the comet.
The touchdown is expected to occur 30 minutes past midnight on Thursday‚ Korea time.
Given that it takes around half an hour for radio signals to reach Earth‚ the mission's success or failure will only be able to be confirmed at 1 a.m. Thursday.
