Has Voyager 1 escaped the Sun yet? Yes, but also no, say boffins

Measuring [magnetic data from Voyager] when it arrives will also be just a little bit harder than it was last week, because the last original member of the Voyager team has retired. Larry Zottarelli, aged 80, left NASA’s employ this week after 55 years on the job. Zottarelli helped to develop Voyager’s on-board computers and has worked on the mission since 1975. CNN reports that he was sent on his way with a handshake from actress Nichelle Nicholls, Star Trek’s Lt. Uhura. NASA is reportedly seeking a replacement fluent in FORTRAN, Algol and assembly language for the Voyagers’ 250 Khz General Electric 18-bit TTL CPUs, complete with single register accumulator and bit-serial access to 2096-word plated-wire RAM.

Lessons From a Decade of IT Failures

Ten years ago, IEEE Spectrum published “Why Software Fails,” an article that examined the underlying causes of notable project failures. A couple of years later, we started the Risk Factor blog, with the goal of tracking technology failures both large and small.

To commemorate the last decade’s worth of failures, we organized and analyzed the data we’ve collected. We cannot claim—nor can anyone, really—to have a definitive, comprehensive database of debacles. Instead, from the incidents we have chronicled, we handpicked the most interesting and illustrative examples of big IT systems and projects gone awry and created the five interactives featured here. Each reveals different emerging patterns and lessons. Dive in to see what we’ve found. One big takeaway: While it’s impossible to say whether IT failures are more frequent now than in the past, it does seem that the aggregate consequences are worse.
