Today is a good day. William and Kate got hitched earlier this morning, and later this afternoon at 3:47pm, Space Shuttle Endeavour is scheduled to lift off on its final mission into low Earth orbit. A bunch of Twitter followers of NASA have front row seats, and President Obama and First Lady Michelle will be there, too.

Science and technology reporter Miles O’Brien is live blogging the launch on BoingBoing here: Space Shuttle Endeavour STS-134 launch: BB liveblog on-site, SpaceFlightNow webcast with Miles OBrien – Boing Boing. I hope that the launch will be successful today, but there are some concerns about the wind. According to O’Brien: “The weather is the story out here today, and specifically: they’ll be watching the wind. Gusts are so forceful out here that my Mac Air just blew right off the table and hit the ground when I stepped away for a moment.” I suppose it’s good on occasion to have a computer with heft!

Y and I are watching a replay of the royal wedding while NASA prepares the shuttle and crew for launch.
