The American space agency, NASA is giving up plans to try to resume communication with its Spirit, which is one of the Mars rovers that landed on the surface of the red planet in 2004.

Spirit and another rover named Opportunity for a planet three months mission to roam the opposite sides of the planet's equator looking for signs of water. Spirit lost communication possibly due to harsh winter on the planet after several years of work.

NASA lost its communication with Spirit about 14 months ago. Scientists were hoping that with the arrival of Martian spring, the rover will be able to recharge it through the solar panels and establish contact.

"We no longer believe there is a realistic probability of hearing from Spirit," NASA said in a statement. The agency added that it will make the last effort on Wednesday to make radio contact with the rover.

Spirit has explored an area on the red planet called Gustav Crater. Opportunity is still working on the red planet and NASA is preparing for follow-up mission scheduled for November this year.
