We've never seen anything like it.

They're typically seen in starburst galaxies, where there's a lot of star formation and large stars don't last very long. They typically explode soon after they're made — where 'soon' is a million years.

It is still on the front burner.

Presumably it's related to the fact this was so close. We may be seeing phenomena we can't see for the (bursts) that are 100 times more distant. We'll be trying to figure out that puzzle for the next days and weeks.

We had long discussions about this, because at the beginning I was a little bit reluctant, because I thought, 'Well, are people going to think that we've got a camera on Mars?' and then, I thought, 'Well, people are far enough along. The audience is smart.' We want to show want show what the rovers are doing and we can't just have stills.

It's kinda up to Matt [Damon]. Maybe to five [films] ... At some point, he's gotta find out who he is.
