A stream bed on Mars and Endeavor comes home this week on planetary radio.

final moments in the air as it arrived in Los Angeles.

We're going to come back to curiosity of course, so tell us a little bit about opportunity.

And it didn't quite make it to the rock targets it was seeking last year before it had to stop for the winter but now that spring is here

It's driven down the inside rim of Endeavor and gotten to this point on Cape York where they are investigating and finding some really strange looking

spherules inside the rock now opportunity has seen a lot of spherules before but
