We didn't get a signal at 8:30 p.m. We hoped we would.

The signal we are looking for is very, very weak, about 1 watt of power -- or like looking for a Christmas tree light on Mars.

I know they have lots of theories and ideas, but I don't know that they're any closer to nailing things down.

We're sprouting new ideas as we go along, and the plan is more or less the same.

Entry, descent and landing are very complex, and a lot of things have to go correctly. That's just part of the risk associated with the mission.

In a way, we feel somewhat complete in the sense that we did go through the things we thought were reasonable. Obviously at this point none of that panned out, but we gave it a good shot.

The international community has shown a real interest in being involved in our search, ... We appreciate their efforts and I think it shows that Mars is something that captivates everyone's imagination.

The market [for farmland] was off but now it is on. You can throw all the old price comparisons out the window.

As time goes by, and I'm not telling you otherwise, we're less confident. At this point, though, we still have a lot of things we can try and we're doing that ... Everybody has the belief that we can still get a signal from the spacecraft.
