Anyone live near the Pacific?


There's a spacecraft hot on the trail of a comet, and it's swinging by Earth for a big speed boost on Tuesday.

Rosetta will make a close approach to Earth on Nov. 13 to reach its final destination—comet 67/P Churyumov-Gerasimenko—about seven years from now.

The 3.3-ton comet chaser, launched on an Ariane 5 rocket by the European Space Agency (ESA) in 2004, will make the close encounter with the planet to pick up almost 9 percent more speed, saving it fuel and hastening its journey.

Rosetta's pass occurs around 3:57 p.m. EST (2057 GMT) and will track above the Pacific Ocean, southwest of Chile before the spacecraft flings back on course. In 2009, Rosetta is slated for another swing-by that will speed it to 86,570 mph (139,300 kph) relative to the Sun.



This object would be moving incredibly fast through the night sky. Would make a good mpeg.

Bugger! I missed the first pass. I'd better set the alarm for 2009!

ESA has released pics' of Austral-Asia taken by the craft on its flyby.

Incredibly, when it was first detected it was considered a unidentified object and even given a asteroid number: 2007 VN84.......If they were reading Radar's posts they would have known it was coming :welldone:

Nice photo though. Finally got some clear skies as well. Checkout the cyclone currently at the top of Western Australia.
