Adam Walton exlpores the legacy of astronaut Neil Armstrong, who died recently at the age of 82, and the future of manned spaceflight. Since the end of the Apollo moon missions forty years ago in 1972, there have been many manned missions including the Space Shuttles, Russian Soyuz, China's Shenzhou programme and the establishment on the International Space Station, but we haven't travelled beyond Earth's orbit. Adam is joined by science journalist Leo Enright who has been covering man's endeavours in space since the Apollo era, and met Neil Armstrong on several occasions. Also, David Baker, former NASA scientist, now editor of Spaceflight magazine, and Chris Barber, founder of the Cardiff based International Space School Educational Trust. The progrmme looks back at the moon landings and looks forward to our next "giant leap" into space.
