Brian Cox and Dara O Briain are back at Jodrell Bank Observatory building-up to one of biggest astronomical events of the decade - a solar eclipse. They are joined by legendary Apollo astronaut Buzz Aldrin who tells them why he believes we must look beyond the moon for mankind's next giant leap. At NASA Brian makes his own attempt to land a lunar module while Dara finds out what happened to the moon rocks brought back from the lunar surface. Liz Bonnin prepares to take to the skies for the perfect view of the eclipse - from above the clouds. And new resident Stargazer, Dr Lucie Green, reveals how to get the most from moon gazing. Plus from behind the scenes at Europe's spacecraft test centre Dallas Campbell gets to grips with the robots which could revolutionise space exploration. And viewers are asked to help search for exploding stars to help refine the known age of the Universe.
