Opportunity Celebrates 3K Martian Days

The NASA rover Opportunity, which on July 2 had been rolling across Mars for 3,000 Martian days, sent home a new color picture of the panorama around its four-month winter "hibernation" spot, according to NASA. It first landed on Mars in January 2004, along with twin rover Spirit. NASA lost communication with the latter in 2011, but Opportunity continues to explore beyond its expected operational life.
