Draft story
Sojourner
A little rover that rolled up to Martian rocks to find out what they were made of.
I’m Sojourner. In 1997, I rolled down a ramp onto Mars. The Pathfinder lander stayed where it arrived. I could drive right up to the rocks.
One of those rocks was named Moe. I backed up to it and pressed my measuring tool against it. The tool looked for clues about the ingredients in the rock, so the team on Earth could compare it with other rocks and soil.
Together, the rover and lander gave scientists clues that Mars may once have been warmer and wetter. My wheels helped take the science to the rocks.
What I did
Drove to rocks and soil and used a tool called APXS to measure what they were made of.
What we learned
Pathfinder’s measurements helped scientists ask whether Mars had once been warmer and wetter.
A detail to remember
My first trip was down a ramp from the Pathfinder lander onto the Martian ground.
