Tomorrow, Nov. 12, may mark the first time humans have soft-landed on a comet. If this is successful it will be courtesy of The European Space Agency’s Rosetta spacecraft which is currently orbiting Comet 67P/Churyumov-Gerasimenko as it speeds through space. Rosetta will release a lander, called Philae, down to the comet’s surface tomorrow while three different space-focused organizations host Rosetta webcasts for all to watch.

ESA spacecraft ROSSETA arives at Comet Churyumov-Gerasimenko (67P)
European Space Agency’s (ESA) Rosseta spacecraft arrived at Comet Churyumov-Gerasimenko Wednesday after a 10 year flight to catch up with the comet.

This image of Comet 67P/Churyumov-Gerasimenko was taken by Rosetta’s OSIRIS narrow-angle camera on 3 August from a distance of 285 km. The image resolution is 5.3 metres/pixel.
Watch the press conference at ESA on Wednesday for the latest in images and how scientists are going to proceed now that Rosseta has reached the comet.
Stunning close up detail focusing on a smooth region on the ‘base’ of the ‘body’ section of comet 67P/Churyumov-Gerasimenko. The image was taken by Rosetta’s OSIRIS narrow-angle camera and downloaded, 6 August. The image clearly shows a range of features, including boulders, craters and steep cliffs. The image was taken from a distance of 130 km and the image resolution is 2.4 metres per pixel.

There will be some amazing science done in the next 2 years by the team at ESA.
Wake up, wake up, Rosetta.

After an extensive mapping phase by the orbiter in August–September 2014, a landing site will be selected for Philae to conduct in situ measurements in November 2014. The image is not to scale; the Rosetta spacecraft measures 32 m across including the solar arrays, while the comet nucleus is thought to be about 4 km wide. (Photo: ESA)
Scientists at the European Space Agency (ESA) sounded Rosetta’s internal alarm clock to reboot the mission after two-and-a-half years of deep space slumber. Once its systems warm up, Rosetta is due to beam a signal back to Earth before it begins to home in on a frozen rock known as 67P/Churyumov-Gerasimenko. It is due to shoot harpoons into the 2.5-mile dirtball before its Philae lander docks on the surface – a move that has never been attempted before.
ESA project scientist Matt Taylor likened the mission to that of the action film Armageddon, in which Bruce Willis lands on an asteroid to save the world from destruction. “We’re not just landing on the Moon, we’re dealing with something dynamic, which is kicking off tons of dust and gas every minute,” he told the Sunday Telegraph. Because Rosetta, which has been sleeping to save power, is so far from Earth, it will take 45 minutes for its signal to reach scientists at mission control. They expect to see a blip on computer monitors between 1730 and 1830 GMT, indicating the spacecraft is up and running again.
Dr. Dan Andrews, a planetary scientist at the Open University in Milton Keynes, said: “We’re waiting to hear Rosetta is alive and healthy. “This wake-up call kicks off a chain of events, during which the spacecraft heats itself up, points itself towards the Sun and gets itself ready. “Remember, this mission is 10 years old – it’s a bit of a stroppy teenager and it’s going to take a while to wake up.” If all goes to plan, Rosetta will arrive at Churyumov-Gerasimenko in August before descending to the comet several months later.
