It's the old shuttle shuffle. The launch of Atlantis for the STS-129 mission has been pushed back by four days to November 16 to accommodate two unmanned rocket launches from Cape Canaveral, as well as the inaugural launch of the Ares I-X, scheduled for October 27.

As antiquated as it sounds, NASA tries to avoid flying during the New Year's holiday because the shuttle's computers are not designed to handle the year-end rollover.I don't know whether to laugh or cry.

Historically, the Shuttle was not launched if its flight would run from December to January (a year-end rollover or YERO). Its flight software, designed in the 1970s, was not designed for this, and would require the orbiter's computers be reset through a change of year, which could cause a glitch while in orbit. In 2007, NASA engineers devised a solution so Shuttle flights could cross the year-end boundary.

Conservative management is probably not too eager to test that fix though. But, as I recall, there have been recent instances of important ground work being suspended during the holiday week anyway, not just flights, so the clocks might be just one of many reasons to let people spend some time with their families.

Laugh, life is too short not to.
