IRON AND ICE
Wake up, Rosetta!
by Staff Writers
Paris (ESA) Dec 11, 2013

Think it's tough getting up in the morning when the alarm clock sounds? Imagine what it must be like waking up 673 million kilometres from the warmth of the Sun and with no coffee. You might need some help ---

Join the 'Wake Up Rosetta' campaign, an international video shout-out to celebrate the end of 31 months of deep-space hibernation endured by ESA's comet-chasing Rosetta. There are some fabulous prizes to be won.

Rosetta was launched in 2004 and has since travelled around the Sun five times, picking up energy from Earth and Mars to line it up with its final destination: comet 67P/Churyumov-Gerasimenko. For the coldest, loneliest leg of the mission, as Rosetta travelled out towards the orbit of Jupiter, the spacecraft was put into deep-space hibernation.

In 2014, Rosetta will complete its cruise towards the comet, rendezvousing with it in August, before putting its Philae lander onto the comet's surface in November, as it begins its journey closer to the Sun.

The time for Rosetta to wake up and prepare for this most exciting scientific adventure is now fast approaching. The spacecraft's internal alarm clock is set for 10:00 GMT (11:00 CET) on 20 January. Once it has warmed itself up, it should re-establish communication with Earth several hours later.

In a competition that opens this week ESA invites you to mark this important milestone in the Rosetta mission by sharing a video clip of you shouting "Wake up, Rosetta!"

You can upload your video clip and share it with the world via ESA's dedicated Facebook page.

Be creative and imaginative - you can include friends, family, colleagues, members of your team, social clubs, and school groups, or even put together a flash mob to create a memorable video shout.

Visitors to the Facebook page can vote on their favourite videos and compete to win some great prizes:

+ Each of the top ten videos will be transmitted with 20 000 Watts of power towards Rosetta and out into the Universe via one of ESA's deep-space tracking stations.

+ Each eligible participant submitting one of the top ten videos will receive a complimentary gift bag comprising a selection of ESA-branded souvenirs.

+ Two of the eligible top ten video authors will be invited to ESOC, our control centre in Darmstadt, Germany, for the VIP event celebrating the first-ever landing on a comet, in November 2014.

The campaign starts today and runs through until 17:30 GMT (18:30 CET) on 20 January. The two winning entries will be announced on 24 January, and the top ten videos will be transmitted into space in February.

ESA also invites you to join in the Wake Up Rosetta campaign via Twitter by following and shouting #WakeUpRosetta 'virtually' at @ESA_Rosetta. You can shout any time, but we're especially keen to see shouts on 20 January between 10:00 GMT and 17:30 GMT, during our dedicated Wake Up Rosetta event, which will be webcast from ESOC.

Once mission controllers have established contact with Rosetta, our @ESA_Rosetta Twitter channel will also wake up, making this the best immediate source for confirmation that the spacecraft is awake and ready for the final leg of its epic journey.

More information about the event on 20 January will be provided soon.

In the meantime, join us in helping to Wake Up Rosetta!

IRON AND ICE
New comet gets astronomers' attention with intricate tail structure
Stony Brook, N.Y. (UPI) Dec 08, 2013
A telescope in Hawaii has captured images of the intricate tail of a comet named Lovejoy as it moves toward its closest approach to the sun, astronomers say. The Subaru Telescope on the big island of Hawaii, with its combination of a wide field of view and high spatial resolution, provided a clear delineation of the complex, wiggling streams in the comet's tail, they said.
