10 Years On Mars: What Spirit & Opportunity Discovered
Jan 24, 2104
A decade ago, a desert-like planet received two visitors that would later make important scientific discoveries and inspire a new generation of exploration rovers. This month marks the 10-year anniversary of Spirit and Opportunity, which landed on Mars in January 2004.
Spirit arrived at the Red Planet on January 3, 2004, carrying six science instruments, along with engineering cameras. Opportunity, Spirit's twin, landed on Mars on January 24, 2004, with the same payload of instruments.
