Houston, we have a press conference

I’m in Houston for Thursday’s press briefings at NASA’s JohnsonSpaceCenter, where we’ll get tons of background about next month’s scheduled space shuttle mission. If you want to get the complete 411 on STS-121, check this NASA TV page for schedule information and this one for links to Webcasts. We’ll be readying lots of stories, video and interactives in advance of the July 1-19 window for Discovery’s launch. And if you have any burning questions about the mission or NASA’s changing spaceflight program, send them along and I’ll see if I can get them answered, either this week or at a later time.
