Podcast appearances and mentions of John Zarnecki

Britain recently began a diplomatic campaign to draw up new rules for responsible behaviour in space; essentially it's a "don't litter" policy intended to reduce the threat posed by decades of irresponsible dumping in orbit. But what's the scale of the problem of space littering, and how might things go wrong? Adam Murphy spoke to John Zarnecki, emeritus professor of Space Sciences at the Open University...

John Zarnecki discusses the advances in space instrumentation over the past few decades.

Matthew Sweet debates how the discovery of alien life might change the way we think about humanity and how it will impact our moral and philosophical universe. Matthew is joined by the best-selling science-fiction writer Stephen Baxter, the science broadcaster and journalist Sue Nelson, the futurist and neuroscientist Anders Sandberg, and one of our leading space scientists, John Zarnecki, Professor of Space Science at the Open University. This event was recorded as part of Radio 3's Free Thinking Festival at The Sage Gateshead on Sunday 4th November 2012.

The landing of the Huygens probe in 2005 unveiled the surface of Saturn's mysterious largest moon for the first time in history. Six years on, the data from the mission and its Cassini mother craft has revealed it to be a fascinating world of methane lakes, rainstorms and cryo-volcanoes. This film brings us the latest news from the orangey world, including audacious plans for a return splashdown. Archive footage appears courtesy of Footagevault.

A brief introduction to this album.

Melvyn Bragg and guests discuss the unique properties of asteroids. They used to be regarded as the 'vermin of the solar system', irritating rubble that got in the way of astronomers trying to study more interesting phenomena. It was difficult or even impossible for an observer of asteroids to book time using the world's best telescopes, because they were regarded as unspectacular objects that could tell us little about the origins of the universe. However, that has all changed. It is now thought that asteroids are the unused building blocks of planets, 'pristine material' that has remained chemically unchanged since the creation of the solar system; a snapshot of matter at the beginning of time. At the moment the Japanese probe Hayabusa is 180 million miles away, pinned to the back of the asteroid Itokawa, attempting to gain our first samples of the chemical composition of an asteroid. Why did asteroids fail to form planets? How do they differ from their celestial cousins, the comets? And are either of them likely to create another impact on planet Earth? With Monica Grady, Professor of Planetary and Space Sciences, Open University; Carolin Crawford, Royal Society Research Fellow, University of Cambridge; John Zarnecki, Professor of Space Science, Open University.
