Episode 93: Exploring the surface of Titan

By Gurbir Dated: January 14, 2021 Leave a Comment

Prof. John Zarnecki

In the early hours of Christmas day 2004, a small probe called Huygens separated from larger spacecraft Cassini. Three weeks later on 14 January it descended through Titan’s atmosphere to make the most distant soft landing in the solar system to date. Huygens transmitted data during its 136 minute descent through the thick atmosphere and a further 130m minutes from the surface until Cassini disappeared below the horizon.

Prof. John Zarnecki was the principal investigator for the UK based team that built the instruments that first made contact on the surface of Titan, Saturn and the solar system’s largest Moon.

In this conversation, recorded in December 2020, prof. Zarnecki recalls the how the mission came about, the science Huygens revealed at the time and today, a decade and a half later. Cassini-Hugens was a joint mission between NASA and ESA. He also shares his views on the value of international collaboration in space.

Space and iconic scientists from history – Online Zoom series starting Jan 2021

By Gurbir Dated: January 3, 2021 Leave a Comment

So 2020 is behind us but we do have some distance to travel down the tunnel before we see the light. I reckon March should do it.  Until then why not join me on a weekly Zoom session about the latest (a) developments in space and (b)  scientific contributions from people in history.

I will be running online sessions via Zoom starting next week. They are organised by the Workers’ Educational Association and are free or £57.60 depending on your personal status for each of the two 9-week “courses” (as the WEA calls them).  Both are online via Zoom. I usually run them as Zoom meetings with lots of discussion and interaction rather than as a webinar. 


C3844979 – Explorers of the Cosmos 
9:30 to 11:30 on Wednesdays from 20/01/2021 to 17/03/2021

Our modern understanding of the universe is the end product of centuries of scientific discoveries by many individuals around the world. Whilst most have been forgotten in history, some stand out like shining stars. What was their profound scientific contribution? Why were they able to make breakthrough when they did?

  1. Nicolaus Copernicus (1473–1543)
  2. Galileo Galilei (1564–1642) 
  3. Isaac Newton (1643–1727)
  4. Henrietta Swann Leavitt (1868–1921)
  5. Albert Einstein (1879-1955)
  6. Edwin Hubble (1899–1953)
  7. Subrahmanyan Chandrasekhar (1910-1995)
  8. Stephen Hawking (1942-2018) 
  9. Jocelyn Bell (1943 – )

C3845094 Astronomy -The New Space Age

17:00 to 19:00  on Thursdays from 21/01/2021 to 28/03/2021

What value does space technology and exploration have for us as individuals, communities and countries? The series of talks has been developed and enlarged from the first successful run in 2020. Topics include:

  1. From the Space Race to the New Space Age. How has human space exploration evolved since the launch of Sputnik in 1957?
  2. Services from space. All those satellites in space, what impact do they have on the quality of lives of people on Earth? 
  3. The Private Space sector. It has been emerging for many years. Has it finally arrived?
  4. Managing the Space Environment.  Can the international community apply the lessons of climate change on Earth to the space environment around Earth and beyond?
  5. Rocket Science. A summary of rocket propulsion. How it all started and how it’s done now.
  6. Militarisation of space. Humans on Earth have always fought on land, sea and air. Is war in space inevitable?
  7. Humans in Space.  In this decade, will humans walk on the Moon again? Will this decade finally deliver the promise of space tourism?
  8. Exploration of the Solar System. Spacecraft have now visited all the 8 planets of the solar system, along with comets and asteroids. What have we learnt?
  9. The Search for Life. It’s been going on for more than half a century. How is it going?

Episode 92: Revisiting Panspermia with Prof. Wickramasinghe

By Gurbir Dated: January 1, 2021 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

New Book – British Interplanetary Society. The Liverpool Years – 1933-1937

By Gurbir Dated: October 12, 2020 Leave a Comment

Working title and Cover

Available in early 2021.

Of the many rocketry societies that emerged around the world in the early 1930s, only the British Interplanetary Society, founded in Liverpool, remains in existence today. This first-hand account from a founding member and first hon. Secretary Leslie Johnson chronicles the days leading up to the establishment of the BIS on 13th October 1933 and its relocation to London in 1937.  

Aircraft, electricity and telephones had transformed the quality of life in the first quarter of the 20th century. This enormous leap in a very short time inspired a generation to unleash its ingenuity. In the shadow of the great depression, talented engineers, scientists and gifted writers awoke to possibilities of new worlds beyond Earth.

Fired by the imagined futures conceived in science fiction magazines including Wonder Stores, Amazing Stories, Astounding Stories and Tales of Wonder, many began to think of space travel as a possibility within reach.

Youth, enthusiasm and a vivid imagination were a constant feature of all Rocketry Societies. Philip Cleator was twenty-five years old when he founded the BIS in 1933 and Leslie Johnson, just Nineteen. In the following year Arthur C Clarke Joined aged sixteen. It was not just Clarke who reveled in writing science fiction, but most who pursued the interplanetary ideals were engrossed in reading or writing science fiction. The formation of the BIS coincided with the advent of science fiction, which also took root initially in northwest England. During these early days, Johnson describes the ease with which members and office holders moved easily between both genres.

The BIS’s persistence is down to the commitment and dedication of its many industrious members during its almost ninety years of existence. But for its formative years in Liverpool, Leslie Johnson bore a significant burden. In this personal account Johnson records those early days and captures the nuances of the time and people who with enormous foresight established and nurtured the BIS through that critical early phase.

Since then, the BIS has helped shape UK’s national space policy and played a critical role as a founder member of the International Astronautical Federation.

Johnson’s book concludes with an epilogue from Gurbir Singh who provides an update on the BIS’s progress. He describes how the BIS has continued to advocate the ideals of interplanetary travel, showcases past and current members who continue promoting the national and international value and ideals of spaceflight.

The book will be available in paperback, hardback and ebook from early 2021.
