Spirit and opportunity rovers
On January 3, 2004, the Spirit Rover made a bounce landing on Mars, followed 21 days later by the Opportunity Rover. NASA’s goal was to operate each Rover for just 3 months. Since then, NASA has received over 500,000 pictures and immeasurable amounts of data, all through SMI's switches. WHile contact has been lost for 6 months, it is likely due to low power, not a switch failure. nonetheless,The opportunity rover has remained operational since its launch in 2003, showing the incredible reliability of SMI’s space switches.
