And it's not even going from 1999 to 2000

You know that, should I ever be allowed to go up in the space shuttle, my mission would be one of those that is scrubbed 10 minutes before launch.
So weather was the reason behind the cancellation of tonight's launch of Discovery. And Friday is looking like a bleak option, since the winds are projected to be fast and furious. According to the AP: "A new launch attempt was set for 8:47 p.m. Saturday, although weather forecasters gave the new time only a 30 percent chance of acceptable weather because of expected strong winds at the launch pad." Forecasters are iffy on that too though, saying that Tuesday may actually be the shuttle's best bet. (Did you know that each scrubbed launch costs NASA $500,000?)
But this is an interesting twist:
"NASA Administrator Michael Griffin said he felt no pressure to stick to the launch schedule, despite NASA's desire to go up before Dec. 17 so that Discovery is back on the ground for the new year. Shuttle computers are not designed to make the change from the 365th day of the old year to the first day of the new year while in flight. The space agency has figured out a solution for the New Year's Day problem, but managers are reluctant to try it if they don't have to do so.
If Discovery is still grounded by Dec. 18, NASA may decide to keep trying anyway through Dec. 26.
'We've got days and days, and we're not even worrying about the clock problem,' Griffin said. 'The clock problem is an annoyance, but it's not a real problem in the sense that we know how to deal with it.'"
This also was supposed to be the first nighttime launch since before the Columbia explosion. Officials wanted to have good views of any foam that would fall off the tanks, so were sticking with daytime schedules. But it was decided that the last launches yielded an acceptable amount of foam, so the go-ahead was given for the nighttime takeoff. An evening launch must be a sight to behold ... from the stands. I still yearn to be on one when it leaves the ground.
