The Sky at Night: Martian Adventures

Patrick Moore celebrates the success of the Martian rovers Spirit and Opportunity, and the fleet of spacecraft now circling the planet which are sending back astounding images in unprecedented detail. Dr Chris Lintott reports from NASA's jet propulsion laboratory in California about the new mission Phoenix which goes to the polar regions of Mars later in 2007, and Dr Lucie Green visits the Mars Yard in Aberystwyth, where Europe's rover ExoMars is being put through its paces.
