Steven W. Squyresis the James A. Weeks Professor of Physical Sciences at Cornell University in Ithaca, New York. His research area is in planetary sciences, with a focus on large solid bodies in the solar system such as the terrestrial planets and the moons of the Jovian planets. Squyres is principal investigator of the Mars Exploration Rover Mission. He is the recipient of the 2004 Carl Sagan Memorial Award and the 2009 Carl Sagan Medal for Excellence in Communication in...
challenge driving five six terrain
Driving in that terrain was a challenge with all six wheels. With five wheels, it was a mess.
bedrock bit decision drive mostly north onto start swing terrain western
We can see most of the crater from where we are right now, and we've made the decision that we're going to traverse around it on its western side. We're actually going to start the drive around the crater by going north a little bit ... to get onto terrain that's mostly bedrock ... before we swing west.
almost cause expected guess mars mystery occasional odd remains root vehicle
The root cause of the reset remains a mystery, but I guess the occasional odd glitch is to be expected from a vehicle that's been on Mars for almost 600 sols.
cases explosions hot perhaps springs trace violent water
It was a hot, violent place with volcanic explosions and impacts. Water was around, perhaps localized hot springs in some cases and trace amounts of water in other cases.

These look like hard outer shells on some parts of some outcrops, and theyre darker and a little redder than the rock that they encrust,

cost easy happened mars problem rover time wrong
Easy problem to find and fix, but it happened at just the wrong time and cost us data, and one more sol, ... Another first for the Mars Exploration Rover Project.
opportunity salty sea
We think Opportunity is now parked on what was once the shoreline of a salty sea on Mars.
driving hang
We're also really getting the hang of driving in this terrain.
changes compelling consider evidence flowing surface water
We've got some evidence, I think, of water flowing through the rocks, and changes in chemistry, I don't think we have what any of us would consider compelling evidence for surface water yet.
landing technique using
We're using the same landing technique that Pathfinder used.
bite landed opportunity waiting
That was waiting to bite us. If Opportunity had landed first, it would have had the same problem.
fact frost involved level might understand wind
Wind has to be involved at some level you figure. Frost might have helped. A frost build-up on arrays could coagulate the dust...but the fact is that we don't understand it very well. But I'll take it.
beautiful believe signature taken truly
We have taken a beautiful 360-degree panoramic image, which I truly believe will be one of the signature accomplishments of this mission,
