Horizon on Titan

This week, the BBC's main science programme, Horizon, will be all about the Cassini-Huygens spacecraft and its trip to Saturn's moon Titan. It will be broadcast tomorrow night (Thursday) at 9pm BST on BBC 2.

Amongst the results that the programme will discuss should be a feature on the radio astronomers who came to the rescue of the Huygens lander. During descent onto Saturn's largest moon, one of the two data channels (channel B) failed and would have meant the loss of at least one of the experiments. However, by using very long baseline interferometry - linking lots of radio telescopes on the Earth to simulate a radio telescope the size of the planet - it was possible to get some of this data back and this became known as 'channel C'. Hopefully Horizon will tell us a bit more about what happened as well as show us some of the fantastic images that Cassini has sent back.
