Launch of Mars Explorer Rover-B

The second Mars Exploration Rover, Opportunity, launched aboard a Delta II launch vehicle on July 7, 2003 from Cape Canaveral. The rover’s primary goal was to examine Martian geology for clues to past water activity on the red planet.

 

The last signal from the spacecraft was heard on June 10, 2018. The mission, planned to only last for three months, officially ended on February 13, 2019.
