The carbon observatory satellite lost this week was from this rocket: en.wikipedia.org/wiki/Taurus_(rocket) It had one other failure before but 6 successful launches. Now it has 6 success, 2 failures. Glory is going to be launched from this one...does that mean it has 25% of launch failure?
Seems to have a similar success rate with one failure in July 2006 (look at all those satellites that got lost!). Knowing the luck so far with interesting satellites this one will ditch as well...better not though, I doubt there will be a cryosat 3
