Jump to navigation Jump to search This is a dynamic list and may never be able to satisfy particular standards for completeness. The following is a list of software bugs with significant consequences. A booster went off course during launch, resulting in the destruction of NASA Mariner 1. This was the result of the failure of a transcriber to pc chips m811 software download an overbar in a written specification for the guidance program, resulting in the coding of an incorrect formula in its FORTRAN software.
1 billion prototype rocket self-destructed due to a bug in the on-board guidance software. In 1997, the Mars Pathfinder mission was jeopardised by a bug in concurrent software shortly after the rover landed, which was found in preflight testing but given a low priority as it only occurred in certain unanticipated heavy-load conditions. In 2000, a Zenit 3SL launch failed due to faulty ground software not closing a valve in the rocket’s second stage pneumatic system. A mis-sent command from Earth caused the software of the NASA Mars Global Surveyor to incorrectly assume that a motor had failed, causing it to point one of its batteries at the sun. NASA’s Spirit rover became unresponsive on January 21, 2004, a few weeks after landing on Mars. Engineers found that too many files had accumulated in the rover’s flash memory.
A bug in the code controlling the Therac-25 radiation therapy machine was directly responsible for at least five patient deaths in the 1980s when it administered excessive quantities of beta radiation. A Medtronic heart device was found vulnerable to remote attacks in March 2008. The year 2000 problem spawned fears of worldwide economic collapse and an industry of consultants providing last-minute fixes. An error in the payment terminal code for Bank of Queensland rendered many devices inoperable for up to a week. The problem was determined to be an incorrect hexadecimal number conversion routine. When the device was to tick over to 2010, it skipped six years to 2016, causing terminals to decline customers’ cards as expired.
