    I just wanted to make a thread that shares news and views about the Rosetta probe project.

    Rosetta is a robotic spacecraft built and launched by the European Space Agency to perform a detailed study of comet 67P/Churyumov–Gerasimenko. It is part of the ESA Horizon 2000 cornerstone missions and is the first mission designed to both orbit and land on a comet.[3]
    Rosetta was launched in March 2004 on an Ariane 5 rocket and will reach the comet in August 2014. The spacecraft consists of two main elements: the Rosetta space probe orbiter, which features 12 instruments, and the Philae robotic lander, with an additional nine instruments.[4] The Rosetta mission will orbit 67P for 17 months and is designed to complete the most detailed study of a comet ever attempted. The mission is controlled from the European Space Operations Centre (ESOC), in Darmstadt, Germany.[5]
    The probe is named after the Rosetta Stone, as it is hoped the mission will help form an idea of how the Solar System looked before planets formed. The lander is named after the Nile island Philae where an obelisk was found that helped decipher the Rosetta Stone. The spacecraft has already performed two successful asteroid flyby missions on its way to the comet.[6] In 2007, Rosetta also performed a Mars swingby (flyby), and returned images.[7] The craft completed its fly-by of asteroid 2867 Šteins in September 2008 and of 21 Lutetia in July 2010.[8] On 20 January 2014, Rosetta was taken out of a 31-month hibernation mode and is continuing to its target.[9][10]
    In 2007, as it approached Earth for a fly-by, the spacecraft was briefly designated as minor planet 2007 VN84 due to it being misidentified as an asteroid.

    Waking up after almost three years of hibernation, a comet-chasing spacecraft sent its first signal back to Earth on Monday, prompting cheers from scientists who hope to use it to land the first space lander onto a comet.

    The European Space Agency received the all-clear message from its Rosetta spacecraft at 7:18 p.m. (1818 GMT; 1:18 p.m. EST)—a message that had to travel some 800 million kilometers (500 million miles).
    In keeping with the agency's effort to turn the tense wait for a signal into a social media event, the probe triggered a series of "Hello World!" tweets in different languages.
    Dormant systems on the unmanned spacecraft were switched back on in preparation for the final stage of its decade-long mission to rendezvous with the comet named 67P/Churyumov-Gerasimenko. Systems had been powered down in 2011 to conserve energy, leaving scientists in the dark about the probe's fate until now.
    Because of the time it took Rosetta to wake up, and the long distance between the spacecraft and Earth, the earliest possible hour for a signal to arrive was 6:30 p.m.

    The lander that is onboard Rosetta (called Philae) just woke up after hibernation to conserve power. Does anyone else feel that the lander will fail? I have a bad feeling about this mission for some reason.


    It is by will alone I set my mind in motion.
