Join Pete and Russell as they look skyward and ask where are all the Aliens. So many planets, so many possibilities and yet are we alone?

In our third and final week looking at great unsolved mysteries Peter and Russell visit the Antikythera Mechanism. This complex analogue computer could predict astronomical positions and eclipses decades in advance. Then off to Peru and the mystery of the Nazca Lines. Why would people carve 70 different images into the Earth? Was this a way to communicate? Who would have done it? Join us as we talk about another two great mysteries.

Did landing the first person on the Moon end the space race or were there other achievements to be had? The first space station, the first pictures and sounds from the surface of other planets, launching new space craft, space telescopes and probes sent to the outer solar system. This week Peter and Russell look at the developments after the Moon landing, the changes in the political climate the ongoing tensions of the cold war and the efforts to cooperate in space. We have a few more sound clips to share of key moments in the exploration of space and the changes happening back here on the ground. Join us as we also take a look at the new players and the ongoing race to make space and other planets part of our future.
