Scientists all around at the world are bidding a fond farewell to 'the little rover that could.'
The Mars Rover, Opportunity, has sent out its last message after a planned 90 day exploration mission on the Red Planet stretched to almost 15 years of record-breaking achievements.
Things looked bleak for the rover in 2011 when the wheel motor began to wear out, but NASA engineers found another way to keep her going - by driving backward.
Reportedly, the last missive sent from the little rover in June amounts to, "My batteries are low, and it is getting dark."
Experts believe a planet wide dust storm covered the rover's solar arrays.
NASA Administrator Jim Bridenstine says they attempted to reach Opportunity more than 800 times before announcing the end of the mission.
Messages with the hashtag 'Thanks Oppy' are pouring in from across the globe.
