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 British mountaineer George Mallory was once famously asked why he was trying to climb Mount Everest and his famous reply was 'because it is there.' That's a compelling argument when you are a mountaineer. But for an $850 million rover mission you better have a better reason than that.

A sol like that gives you confidence. I'm really convinced now that we're able to keep the vehicle safe.
calls certainly good guy land looks promised rugged team turn
That very rugged stuff. There is a guy on our team who actually calls this the geologic promised land. I don't know if it's going to turn out to be that good or not and I don't know if we'll ever get there, but it certainly looks interesting.

That's no Mt. Everest, but it's a heck of a climb for our little rover. When we first touched down at Gusev Crater on Jan. 4, 2004, the Columbia Hills looked impossibly far away.

area climb climbing field found gained geologist good motivated plotting point rock science spirit time
This climb was motivated by science. Every time Spirit has gained altitude, we've found different rock types. Also, we're doing what any field geologist would do in an area like this: climbing to a good vantage point for plotting a route.

We hope to survive another winter on Mars.
course far five hills sit
Our requirement for how far we should be able to traverse over the course of the mission, was 600 meters. These hills are five times that far away. OK, so don't sit here and think, 'Oh, we're going to go to the hills.' We're going to go 'toward' the hills.
