Right now on NASA TV the Mission Status Briefing they are stating that there will be no spacewalk to fix the tiles on the underside of the orbiter. There is "no danger to the crew." "I am 100% confident that there will be no problems."
Famous last worlds.
I'm sorry, but in the immortal words of Han Solo: "I've got a bad feeling about this."
I don't know, and I'm the first to admit I don't have all the data, but my gut tells me that this decision could be trouble. And the time is 9.47 PM EDT on August 16, 2007.
If - God Forbid - something happens, it will spell the end of the shuttle mission right away. There will be no more ISS contruction missions, no vitally important mission to the Hubble Space Telescope. We will not have the capabilities to launch people into orbit until 2014 with Orion.
Please God, let me be wrong.
