Mistakes and lessons learned

Risk areas in Embedded Systems Development: Development Process

Every project, irrespective of the domain, has processes associated with it. These process make sure the development goes through smoothly and mistakes are identified before they become catastrophic. They are a result of years if lessons learnt and experience. However, we, being humans are not very inclined with following processes. Whats more, is that when […]

Priority inversion problem

Mars pathfinder is the first mission of NASA’s Discovery program for investigating the atmosphere and other factors of Mars. Although the project was successful from scientific point of view, its path to success was not smooth at the beginning. The system suffered from priority inversion problem – a real-time synchronization problem – soon after it […]

Mars Pathfinder – What really happened?

Launched on December 4, 1996 by NASA aboard a Delta II booster, the Mars Pathfinder landed on July 4, 1997 on Mars’s Ares Vallis, in a region called Chryse Planitia in the Oxia Palus quadrangle.
