According to NASA, all systems are go for tomorrow's launch of space shuttle Discovery to the International Space Station. Discovery will be transporting additional pieces of the Japanese Kibo laboratory module—including the large Japanese Pressurized Module and a robotic arm—as well as a new toilet pump to replace on that has failed (talk about trouble getting a plumber out to your house!). Additionally, Discovery will deliver Greg Chamitoff and return Flight Engineer Garrett Reisman, who has spent the past three months on the space station.
This mission will be the largest payload ever transported to the ISS and includes three spacewalks to install equipment.
With launch scheduled for 5:02pm EDT, NASA expects an 80 percent chance of favorable weather at launch time. And since this launch will be happening at a time when I'll be awake, I expect to watch the streaming webcast of it.
