Have you guys heard about this one ?
Gaia observatory link link QUOTE "The satellite will determine the position, colour and true motion of one thousand million stars and over 100,000 objects in our Solar System. Gaia will also identify as many as 10,000 planets around other stars. " QUOTE "Gaia will measure distance (from parallax) out to ~100,000 parsecs; for stars ~10,000 pc away, with a Vmag of ~<15, Gaia will measure their distances accurate to ~10-20%." You can also read about it here http://www.spaceflightnow.com/news/n0407/06mapping/ http://en.wikipedia.org/wiki/Gaia_probe or check the European space site |

Now this is unusual. Back on May 24th Spaceflight Now revised their launch schedule and moved Soyuz/Gaia forward ten days. According to them, launch of Gaia will now occur on September 19th.
Worldwide launch schedule Edit 6/24: BUMMER! The launch schedule got updated again just three days after this posting, and Gaia was pushed waaaayyy back. Late in the year, no definite date. Update 6/28: Spacecraft is complete, tested, and ready to ship out. Testing Completed Ready to depart Update 8/8: According to the latest GAIA -DPAC newsletter, they are going to ship most of the spacecraft out in early September, with the sunshield sent to South America a few days later. They are aiming to launch during the time period Nov 17th to Dec 5th. Update 8/24 Most of the spacecraft has now arrived in French Guiana, and Spaceflight Now has a pretty good article about that, launch preparations and the mission as a whole. Article And now Gaia has its own blog site: Semi official Gaia blog site |

I saw on the ESA Gaia web page that they are replacing some part based on a problem on an already launched mission, and the new target launch date is Dec 20, 2013. Anyone know what the other craft was, and what the part is?

Anyone know what the other craft was, and what the part is? The part is a clock generator for an X-band transponder; equivalent parts apparently went wrong in some O3b Networks communications satellites launched in June. |
