Steve Squyres Rocks Quotations

This was an inhabitable environment on Mars. This was a shallow sea. These rocks ... it's a salt flat. These are the kinds of environments that are very suitable for life.

They provide a wonderful glimpse into what Mars was like in the earliest part of its history, ... It was a violent place. It was a place where meteorite impacts were happening frequently. It was a place where there volcanic explosions happening frequently. Hot stuff was raining from the skies. There was water. When rocks were deposited, water would flow through those rocks and change their chemistry. This is a glimpse into the ancient past of Mars.

The berries are more numerous here, and some seem to be smaller than any weve ever seen. And interestingly, some dont appear to be round. Were still debating what this means, but clearly the hematite is distributed a bit differently here than it has been in any other rocks weve seen at Meridiani,

We have concluded that the rocks here were once soaked in liquid water. It changed their texture, and it changed their chemistry. We've been able to read the tell-tale clues the water left behind, giving us confidence in that conclusion.

The rocks, to a great extent, look swept clean. It's a much cleaner surface than what we had a right to hope for.
