Exclusive update from LRO mission scientist, Michael Wyatt:
Amazing launch!

I’ll get some pictures organized tonight and share another update tomorrow morning.

Hope you enjoyed the launch.

Exclusive update from LRO mission scientist, Michael Wyatt: It’s turning out to be a busy, chaotic week at the Kennedy Space Center.

You would expect that, considering that NASA has two major launches scheduled. As I wrote about yesterday (see below), the space shuttle Endeavour was scheduled to launch early this morning, and everyone was brimming with anticipation. But NASA had to scrub the launch for a second time because of a leak detected in the gaseous hydrogen venting system outside the shuttle’s external fuel tank. These things happen, and it’s better to be safe than sorry, of course, but still it can be frustrating — most of all for those most closely involved in the planned flight. Read the full update.
