From the "At Least It Isn't Only Me" File…

Again from Ars Technica today…

At least it isn’t just me who puts things together backwards… In the Ars article of 2013 July 9 entitles Parts installed “upside down” caused Russian rocket to explode last week on July 4 a Russian rocket, carrying a GLONASS navigation satellite (Russia’s answer to GPS – for some reason Russia doesn’t trust the U.S. system…) because, get this: Because various sensors were installed upside down!

Each sensors had an arrow that was suppose to point toward the top of the rocket, but multiple sensors were pointing downward instead. Anatoly Zak reports on RussianSpaceWeb.com that:

Each of those sensors had an arrow that was suppose to point toward the top of the vehicle, however multiple sensors on the failed rocket were pointing downward instead. As a result, the flight control system was receiving wrong information about the position of the rocket and tried to “correct” it, causing the vehicle to swing wildly and, ultimately, crash.

Some days it doesn’t pay to get out of bed…
