Mars, Gagarin, SETI and British Space Programme

By 4 Comments

As part of the WEA’s Festival of Ideas, I will be presenting a series of four two-hour online Zoom meetings (not webinars) with Q&A. The cost for each is £10.00 but depending on personal circumstances – free.

Exploring Mars: 09:45 – 11:45 22 Feb 2021
It’s getting busy on Mars. Currently, Mars has two spacecraft on the surface and another five in orbit from the USA, Europe and India. In February three more will arrive from the United Arab Emirates, USA and China. NASA will attempt to land its most advanced Martian rover called Perseverance on Thursday 18th February, and China will attempt to land its rover in May.

What have we learnt about the red planet’s surface, atmosphere and chemistry? Did Mars have life in the past? Is there life there now? What does the evidence show so far? The dream for humans going to Mars has been written about for centuries are we about to see it happening?

The Day the Cosmonaut came to Manchester 09:45 – 11:45 1 Mar 2021
Three months after the world’s first human in spaceflight, that human, USSR cosmonaut Major Yuri Gagarin, spent five days in Britain. Mostly in London but on 12 July 1961 he came to Manchester for the day. At the time, he was the only human to have orbited the Earth. Why did he come to London and Manchester? Where did he go and who did he meet and what was the impact of his visit between the East and West in the midst of the Cold War?

Based on my 2011 book – Yuri Gagarin in London and Manchester

The search for life beyond the Earth 09:45 – 11:45 8 Mar 2021
The search for life beyond the Earth has been a constant quest in human history. Developments in the 20th century in radio astronomy and space technology have sped up the search for life in the solar system and the Search for Extraterrestrial Intelligence (SETI). How is that search going? What is the latest progress and current status?

The rise, fall and rise again of the British Space Programme 09:45-11:45 15 Mar 2021
Did you know that Britain is the only country to have developed rockets, launched a satellite and then … pulled the plug on its space programme? That was in 1971 but now the space industry in Britain is thriving once more. This presentation is a look back at early space developments in Britain and why it is thriving again today.

Episode 92: Revisiting Panspermia with Prof. Wickramasinghe

By Leave a Comment

Prof. Chandra Wickramasinghe

The idea of Panspermia, that life exists throughout the universe and spreads via asteroids, comets and cosmic dust, has been around for a long time. Two of the strongest advocates were Professor Fred Hoyle and Professor Chandra Wickramasinghe. 

In this episode I spoke at length with Professor Wickramasinghe about his long and distinguished career championing the idea of panspermia the covering the topics:

  • Initial difficulties in establishing Panspermia as a legitimate and respectable topic for scientific study.
  • Professor Wickramasinghe’s journey in 1960 form Cylon (as it was known at the time) to Cambridge as Hoyle’s Phd student.
  • His personal recollections of Fred Hoyle (initially his Phd supervisor and later collaborator) and Arthur C Clarke, who had made Cylon his home in the late 1950s.
  • His views on how the research on Panspermia has developed and where it stands today

Episode 30: December 27th 2009 Prof. Barrie Jones

By Leave a Comment

Forty years ago a revolutionary higher education institution for adults was established in the UK. Students enrolled in the Open University two years later in 1971. This model of higher education has now spread across the globe.

Today, the Open University plays a strong and active role in the exploration of space in collaboration with ESA and NASA. The first bit of human technology to touch the surface of  Titan was an instrument made by a team at the OU under Professor  John Zarnecki. The unsuccessful Beagle 2 mission to Mars was headed by OU Professor Colin Pillinger.  Currently, it is working on  projects including Darwin, Stardust, Rosette and Genesis.

Today’s episode is a special recording with Professor Barrie Jones of the Open University. Special because during the Eighties, I studied several of the courses which he helped to develop and presented on the the late night OU TV programs.

Professor Jones joined the Open University in 1972 and since 2006 is the emeritus professor of astronomy.  He recalls people he worked with at Cornell including Tom Gold, Frank Drake, Carl Sagan and the early days of Gamma Ray astronomy from balloons.

His distinguished career has spanned several decades, arguably the most scientifically productive decades in the history of astronomy, over that time, his research has spanned the electromagnetic spectrum. Although retired, he continues to write, research and lecture mainly in Astrobiology.

Initially he started working on Gamma Rays at Bristol University and then Infra Red astronomy during his time at Cornell. I asked if he had been involved with radio and optical astronomy too?

====================================

As the UK government recently announced further cuts in the higher education budget, today’s quote is from Derek Bok .

If you think education is expensive – try ignorance.

Professor Mark Brake from the University of Glamorgan has an eclectic interest. An academic, broadcaster and author of science and popular science books, he is the organising chair for the the third conference of the Astrobiology Society of Britain: ASB3: The Living Universe, will take place in Cardiff between July 1-4, 2008. We spoke about the relationship between science & science fiction and astrobiology.
