California, Jan 24: NASA's Opportunity rover begins its 16th year on the surface of Mars today. The rover landed in a region of the Red Planet called Meridiani Planum on Jan. 24, 2004, sending its first signal back to Earth from the surface at 9:05 p.m. PST on Jan. 25, 2004.

The golf-cart-sized rover was designed to travel 1,100 yards (1,006 meters) and operate on the Red Planet for 90 Martian days. It has traveled over 28 miles (45 kilometers) and logged its 5,000th Martian day back in February of 2018.

"Fifteen years on the surface of Mars is a testament not only to a magnificent machine of exploration but the dedicated and talented team behind it that has allowed us to expand our discovery space of the Red Planet," said John Callas, project manager for Opportunity at NASA's Jet Propulsion Laboratory in Pasadena, California. "However, this anniversary cannot help but be a little bittersweet as at present we don’t know the rover’s status. We are doing everything in our power to communicate with Opportunity, but as time goes on, the probability of a successful contact with the rover continues to diminish."

Opportunity's last communication with Earth was received June 10, 2018, as a planet-wide dust storm covered the solar-powered rover, eventually blocking out so much sunlight that the rover could no longer charge its batteries. Although the storm eventually abated and the skies cleared, the rover has not communicated with Earth since then.

Opportunity and its twin rover, Spirit, launched from Cape Canaveral, Florida, in 2003. Spirit landed on Mars in 2004, and its mission ended in 2011.
