Last man on the Moon, Captain Gene Cernan, and Apollo 9 lunar module pilot Rusty Schweickart join Space Boffin Richard at Spacefest in Tucson, Arizona. Apollo 17 commander Cernan expresses his frustration about the state of the space programme and Rusty Schweickart warns of the asteroid threat to Earth. We also hear from astronomer Nick Howes, spaceblogger Emily Carney, Thomas Zurbuchen on how small satellites could be the future for big science missions and the going rates for astronaut autographs.

This month the Space Boffins get to grips with relativity, watch as British astronaut Tim Peake manoeuvres a Mars rover in a cave, and go inside a section of NASA's new giant rocket. With their guest, writer and poet Simon Barraclough, they also discuss space station alarms (with appropriate sound effects) and celebrate the flight of America's first manned mission, Mercury 3.

On 9 May, Mercury will be seen as a black dot silhouetted against the Sun and this rare event enabled astronomers of the 17th century to work out how vast the universe was. But this transit isn't just phenomenally important historically: it has huge implications in our search for extraterrestrial life, as Graihagh Jackson finds out... Like this podcast?

Space Boffins Sue Nelson and Richard Hollingham bring news of space sofas, super flat floors and Martian sunsets. They are joined at The Open University by ExoMars mission principal investigator Dr Manish Patel to discuss his work on the NOMAD instrument, which is currently on its way to Mars on board the recently launched spacecraft, and how you prepare for success and failure. Richard also reports from Alabama, gliding across NASA's Flat Floor Facility on a bed of air beneath a giant solar sail. While having fun at NASA's Marshall Spaceflight Centre in Huntsville, he hears about NASA's Near... Like this podcast? Please help us by supporting the Naked Scientists

Buzz Aldrin is the legendary Apollo 11 and Gemini 12 astronaut who made history in 1969 when he became one of the first men to walk on the lunar surface. Today, he has his sights firmly on the future - specifically Mars. The visionary tells Space Boffin Sue Nelson about his cycling orbits to the red planet, why he wouldn't go to Mars himself, what he thinks of the ESA director general's plans for a Moon village and which item of jewellery he's wearing was a gift from Mohammed Ali.
