Computer Date Glitch May Limit Next Shuttle Launch

n3hat writes "Reuters reports that the next Space Shuttle mission may have to be deferred if it gets too close to the New Year because the onboard computers do not handle the changing of the date in the same way as the ground computers. From the article: '"The shuttle computers were never envisioned to fly through a year-end changeover," space shuttle program manager Wayne Hale told a briefing. The problem, according to Hale, is that the shuttle's computers do not reset to day one, as ground-based systems that support shuttle navigation do. Instead, after December 31, the 365th day of the year, shuttle computers figure January 1 is just day 366."

This is not a bug ....

Imagine you are a member of the shuttle design team and you can make a choice (for the next 20 years) to either know for sure that you're with the kids at home on X-mas and New Year .... or you can suggest a software feature that could result in your New Year's Eve being spoiled down the road because you have to be for days in a dumb control room. Hey, what would you do??

And I still remember, when I was a kid, that we had that Apollo flight during X-mas. I think it was the one that would for the first time go behind the moon. Someone in the control room that year made it into an important enough person on the Shuttle program so that this WOULD NEVER HAPPEN AGAIN. :-)

You know, people like you give programmers a bad rep. You just dive in for the fix without knowing the cause - and on top of that add a few bugs that are even harder to iron out if you happen to be the only person knowing that code segment.
