Also in the news just this morning, looks like the "James Webb" telescope is having major 'birthing pains':
"Telescope promises new look at universe - if NASA can get it into space."
http://www.physorg.com/news201098260.html
"construction of NASA's next big telescope has been so hurt by delays and cost overruns that even its staunchest champion in Congress reached a breaking point.";
"at least $1.5 billion over budget and three years behind schedule."
"When Webb bleeds, the rest of space science hemorrhages,""
"We are aiming to see the realm between 250 million years after the big bang to about 400 million years afterward,"
"Specifically, the Webb and its 21-foot infrared mirror will test the theory that the first galaxies were disorganized and composed of "very large, very bright and short-lived stars,"
I hope they get this one sorted out quickly & they don't take any shortcuts in doing so. Its planned to have this puppy parked 1 million miles up at the Earth-Sun Lagrange point. No chance of a shuttle rescue mission there, folks.
Cheers
