After the success of the Sojourner rover, priziv.org wanted to send more rovers to learn about Mars. So, in 2003, they sent two rovers come the Red Planet. The rovers were named Spirit and also Opportunity. Together, they were part of the Mars exploration Rover mission.Spirit and Opportunity to be made as twins. They both carried all of the very same scientific instruments. And each was around the dimension of a golf cart.

On Earth, wherein there is water, over there is life. Spirit and Opportunity were sent out to Mars to find much more clues around the history of water there, and to check out if the Red Planet could ever have actually supported life. To do this, scientists sent the 2 rovers to two different landing sites. The rovers came down on opposite sides of the planet.

Spirit landing in a region called Gusev Crater. Scientists wanted to check out the crater since they thought it might have hosted water lengthy ago. From photos taken through satellites, researchers thought that looked favor several large rivers flowed into Gusev Crater.Opportunity arrived on the various other side that Mars in one area called Meridiani Planum. This an ar was nice since it to be a flat, safe spot for the rover come land. Also, research studies with a satellite about Mars proved that it could contain a mineral dubbed grey hematite. On Earth, grey hematite is often found in the visibility of water.

On that is journey, soul took countless photos the Mars with its camera. They were the very first color photos take away by a rover on an additional planet. Spirit also found several indicators of previous water, and also evidence that geothermal, or volcano activity. It explored sites that may have been warm springs numerous years ago.

In this photo, you have the right to see where spirit dragged among its wheels and churned up part soil. Here, it discovered a light-colored mineral referred to as silica. Top top Earth, this sort of silica normally exists in hot springs, where life as we know it regularly finds a hot, happy home. Perhaps ancient microbes top top Mars did as well!

Not to it is in outdone by its twin, Opportunity also took many shade photos of the Martian landscape. It discovered evidence of water, too. Opportunity studied layers of mineral in the rock close to its landing site. The proof it built up suggested that its landing site was as soon as the shoreline of a salty sea.

The rocks the Spirit and Opportunity studied confirmed scientists that a lengthy time ago, water on Mars may have looked a lot like water on Earth. Mars once had actually lakes and rivers ~ above the surface.
