What evidence of water on Mars did the Mars Pathfinder find?
This photo taken from the Pathfinder lander shows evidence of water at Ares Vallis, Mars. Scientists examining rocks called Barnicle Bill (lower left), Yogi (upper right) and Whale rock (a log-shaped rock at the top of the photo) find extensive oxidation (rusting) of iron on the rocks’ surfaces.
What did Mars Pathfinder discover?
The Pathfinder mission led to multiple scientific discoveries about the red planet, including the following: Panoramic images of Pathfinder’s landing site at Ares Vallis and the presence of rounded pebbles and cobbles suggested that Mars had a warmer, wetter past.
What evidence did the Curiosity Mars rover discover?
The space agency’s Curiosity rover made the surprising discovery while investigating clay-rich sedimentary rocks around its landing site in Gale Crater, a former lake that was made when an asteroid struck the Red Planet roughly 3.6 billion years ago.
What explored Mars in 1997?
NASA’s Pathfinder mission
Mars exploration took a big leap 20 years ago today. On July 4, 1997, NASA’s Pathfinder mission touched down on the Red Planet, delivering an eponymous lander and a small rover called Sojourner — the agency’s first wheeled Mars craft — to the surface.
Why did NASA send Pathfinder to Mars?
NASA’s Mars Pathfinder was designed primarily to demonstrate a low-cost way of delivering a set of science instruments and a free-ranging rover to the surface of the Red Planet. In addition to its engineering accomplishments, Pathfinder provided significant data on Mars’ geology and meteorology.
Who sent the first rover to Mars?
NASA’s Mars Pathfinder

When did the Mars Pathfinder Land on Mars?
Mars Pathfinder Mars Pathfinder was launched December 4, 1996 and landed on Mars’ Ares Vallis on July 4, 1997. It was designed as a technology demonstration of a new way to deliver an instrumented lander and the first-ever robotic rover to the surface of the red planet.
What was the name of the NASA rover that landed on Mars?
NASA’s Opportunity Mars rover mission is complete after 15 years on Mars. Opportunity’s record-breaking exploration laid the groundwork for future missions to the Red Planet. In deploying its first instrument onto the surface of Mars, the lander completes a major mission milestone.

When did NASA start the search for life on Mars?
However, the exploration of Mars has been intertwined with NASA’s search for life from the beginning. The twin Viking landers of 1976 were NASA’s first life detection mission, and although the results from the experiments failed to detect life in the Martian regolith, and resulted in a long period with fewer Mars missions,…
