Spirit & Opportunity

Mars//Rover robotics, 2003-2018


Twin rovers launched in 2003, Spirit and Opportunity were designed to search for signs of past life on Mars. The rovers contributed many important findings, including the notable ‘blueberries’ or spherical formations produced by rising, acidic groundwater and other traces of water activity. This was a monumental discovery as it suggests conditions could have been suitable for sustaining microbial life.

Built and designed to withstand the dusty and difficult terrain of Mars, Opportunity’s nimble Maxar-built robotic arm far outlasted its 90-day mission and traveled 28 miles over 14 years.

Maxar’s robotic arms are well-tailored for lunar landers, rovers, and other surface operations. NASA recently selected Maxar to deliver a flight spare from Spirit and Opportunity for use on the Moon.
