Dr Kevin Fong convenes a panel of astronautical minds to discuss the next decade or two of space exploration.

2021 was an eventful year in space. Captain James Kirk a.k.a William Shatner popped into space for real for a couple of minutes, transported by space company Blue Origin's tourist rocket New Shepard. Elon Musk's Space X ferried more astronauts and supplies between Earth and the International Space Station, using its revolutionary resuable launchers and Dragon spacecraft. On Mars, the latest NASA robot rover landed and released an autonomous helicopter - the first aircraft to fly on another planet.

2022 promises even more. Most significantly NASA plans to launch the first mission of its Artemis programme. This will be an uncrewed flight of its new deep space vehicle Orion to the Moon, propelled off the Earth by its new giant rocket, the Space Launch System. Artemis is the American space agency's project to return astronauts to the lunar surface and later establish moon bases. China has a similar ambition.

Are we at the beginning of a new space age and if so, how have we got here? When will we see boots on the Moon again? Could we even see the first people on Mars by the end of this decade? Even in cautious NASA, some are optimistic about this.

Kevin's three guests are:

Dr Mike Barratt, one of NASA's most senior astronauts and a medical doctor, based at the Johnson Space Center in Houston, Texas
