Glitch may force NASA to launch shuttle early
Dec. 6 slotted for Discovery
BY TODD HALVORSON FLORIDA TODAY
HOUSTON - NASA faces a Dec. 17 deadline to launch Discovery and avoid computer failures that could appear if the shuttle and its astronauts are flying during the year-end computer clock rollover from 2006 to 2007, officials said Monday.
The next chance to launch would be Jan. 14.
Here's the situation:

In which language have they programmed the control computers ? In COBOL ? ;-) Just curious !

My first reaction was that this simply HAD to be a parody, such as the Onion story about the Mars rovers getting bored and sending snide messages. No such luck, apparently.

Sheesh....it's Y2K all over again! And how many millions (or billions) have we spent to "upgrade" the shuttles? I find this kinda hard to believe!

I have always thought that this was a professional organization not a bunch of kids playing with technology.

It's amazing how casually we criticize without seeking explanations. I remember reading a story several years that explained that the shuttle computers still are 486-based. The reasoning then was that the 486 had been tested to death, had fewer bugs, and moreover were fast enough to respond to and control the mechanics of the shuttle. KISS is still worth considering when it comes to safety and reliability.

Actually, the '486 was not even a gleam in Intel's eye back in the 70's when the computers on the Shuttle were specified.
Read the story at http://history.nasa.gov/computers/Part1.html
It's good stuff!

In the best organizations, the two are often indistinguishable. -B

Seems the title is a bit misleading. It is the Shuttle computers that cannot handle going from Day 365 to Day 1. The ISS computers are just fine. The article also states that NASA engineers have a contingency solution should the need arise.
