Spirit & Opportunity is one of my passion is. The both twin are the eyes and our ears about what will happens  for the next generation regarding on the resultant, whereby,vital things that human can learn about. No more secret, no more questionnaire, no more doubt and many more we can expose.

The Mars Exploration Rovers consists of twin probes that are controllable rovers that move freely on the surface of Mars.The rovers are:

• Spirit (MER-A)
• Opportunity (MER-B)

Missions to Mars - Spirit and Opportunity

The Mars Exploration Rovers consists of twin probes that are controllable rovers that move freely on the surface of Mars.The rovers are:

• Spirit (MER-A)
• Opportunity (MER-B)

Spirit was launched on June 10, 2003 at 1:58 PM EST (Pad 17-A) and landed on Mars on January 3, 2004. 

Opportunity was launched on July 7, 2003 at 11:18 PM EST (Pad 17-B) and landed on Mars on January 24, 2004.

Both were launched from the Delta II rocket which was also responsible for launching all Mars related missions: Mars Global Surveyor in 1996, Mars Pathfinder in 1996, Mars Climate Orbiter in 1998, Mars Polar Lander in 1999, Mars Odyssey in 2001, and Mars Phoenix in 2007.

The tall object on the probe is the "pan-cam" and is designed to be the height of an "average" human so the proper perspective can be achieved. Additionally, the wing like structure is the solar panels, used to recharge the batteries. While the mission was only expected to last a few months, both probes are still operating until it turn to stuck in sand silt where it put the both probes lonely for the long period on vast land something in Mars since 2010.

The purpose of the rovers are to examine closely the chemical makeup of the rocks and soil. Special instruments on the rovers include spectrometers and a rock cutting tools. While the data is still being collected and analyzed, the results are wonderful - water is exist at some point on the Martians The Spirit rover carries a memorial plaque dedicated to the crew of the Space Shuttle Columbia - the loss of the Space Shuttle on February 2, 1003. more history :)
