Radio Interviews on Mars and Saturn

Just listened to some great interviews on Mars and Saturn. This is the
intro to the one on Mars:

The Mars Global Orbiter has come up with what looks like conclusive
proof of substantial rivers and waterflow on Mars, possibly several
billion years ago. It provides clear, unequivocal evidence that some
valleys on Mars experienced the same type of on-going, persistent
water flow as rivers do on Earth. We spoke to Ken Edgett at Malin
Space Systems in San Diego, whose team created and controls the
Orbiter camera. Ken gives us a detailed report on what these amazing
pictures reveal.

and this is the one on Saturn:

Approaching Saturn – Cassini heads closer to historic rendevous -
After the success of its Jupiter by-pass, the Cassini spacecraft is
now focusing on its core mission – the journey to Saturn. In part two
of our interview with Cassini team leader Carolyn Porco at their HQ in
Colorado, we get an exclusive preview of the content of the first
Saturn images coming in from Cassini. Carolyn also gives us a detailed
description of what lies ahead and how this mission could unlock the
key to some of Saturn's greatest mysteries.
