Episode 99 Professor Stamatios Krimigis – Exploring the Solar System with Voyager

By Gurbir Dated: September 9, 2022 Leave a Comment

This episode was recorded in Athens in July 2022 during Cospar 2022 and he speaks about his remarkable career guided in large part by his mentor, physicist James Van Allen.

Professor Stamtios Krimigis

He started studying physics at the University of Minnesota in the same month that Sputnik was launched. A chance meeting with James van Allen led Stamatios Krimigis to build instruments for Mariner 3 and 4. Eventually assigned as the Principle Investigator for the charged particle instrument on the voyager program which was initially known as Mariner Jupiter Saturn 77 program.

It is released today to mark his 84th birthday tomorrow on September 10th. Audio and youtube video below.

Pam Reid speaks on BBC Radio Merseyside about her father’s Memoir – My personal History of the British Interplanetary Society

By Gurbir Dated: July 12, 2022 Leave a Comment

Founded by Phil Cleator on Friday 13 October 1933 , the British Interplanetary Society exists to this day. BIS members include Arthur C Clarke, Carl Sagan, George Bernard Shaw, and Robert Heinlein. In 1933 Leslie Johnson was 19 and Clarke, aged 16, joined in 1934.

Leslie Johnson – My Personal History of The British Interplanetary Society 1933 – 1937 Liverpool

The initial aims of the BIS were to convince the public that space travel really was possible and help develop the technology to make it happen. It was an ambitious goal, futuristic, perhaps even reckless. A tough challenge when most people would not have seen an aeroplane up close, let alone ridden in one. Speke airport, now Liverpool John Lennon, was opened in July 1933. Movies were just turning into talkies, the BBC was founded in 1922 large populations geographically separated could share the same experience without having to be in the same place at the same time. Something that was possible for the first time in human history.

Today we are familiar with terms such as satellites, rockets, spacecraft and astronauts but in the 1930s they did not exist. Very few could visualise and understand these concepts and let alone the IDEA of space and space travel.

Like many other leading economies, Britain has a flourishing space programme today. I would suggest it started in Liverpool almost 90 years ago. Yes, despite 13th October 1933 being a Friday, the BIS is still flourishing today as the oldest space advocacy group in the world.

Birth of the Indian Space Research Organisation

By Gurbir Dated: July 6, 2022 Leave a Comment


This article was first published in the May 2022 edition of the British Interplanetary Society publication – Space Chronicles.


Three weeks after its extraordinarily ambitious mission, the crew of Apollo 11 splashed down in the North Pacific, and the Indian Space research Organisation (ISRO) came into being on 15 August 1969. At that time, it was still operating under the Department of Atomic Energy, where its predecessor, the Indian National Committee for Space Research (INCOSPAR), was founded in 1962. In the same year that the Apollo programme in the USA ended, India established the Department of Space in 1972 and brought ISRO under its management. This is the ISRO that has designed, built, launched and operates the 50-plus spacecraft of the 3500 operating in space today.

Today, its space assets provide services to its security forces, but it did not start that way. India’s space programme is probably the only national space programme that began with plans only for economic and societal development. Space programmes in the USA, USSR, China and elsewhere arose to serve a national security imperative. ISRO has met many of its original objectives for more than half a century. India’s assets in space provide services for communication, television, navigation and Earth observation. For scientific research, India has Astrosat, a space telescope in Earth orbit, Chandrayaan-2 in lunar orbit and since 2014, a spacecraft in Martian orbit. Some of India’s spacecraft provide services for the international community, including remote sensing, search & rescue and navigation for civil aviation.

One objective explicitly ruled out by its first charismatic chairman, Vikram Sarabhai, in 1969 was a human spaceflight. In 2018, India’s Prime Minister announced a new goal. Called Gaganyaan, its task is to place an Indian crew in low Earth orbit using an Indian launch vehicle launched from Indian soil by 2022. A variety of issues, especially the global pandemic, have ensured that the timeline will not be met, but the programme remains active. In January 2022, S. Somanath was appointed as Chairman. As Russia’s space activities diminish, opportunities will arise for others, and India is well placed to exploit them.  

ISRO will ramp up activities that will include the launch of OneWeb’s satellites, the inaugural flight of its Small Satellite Launch Vehicle, the second test flight of its reusable space plane, the third mission to the moon complete with a lander and a rover and a launch abort test for its Gaganyaan programme. I expect ISRO to make a significant announcement on 15th August 2022.

New Book – Leslie Johnson’s memoir. My Personal History of The British Interplanetary Society – Liverpool 1933 to 1937

By Gurbir Dated: May 20, 2022 Leave a Comment

My Personal History of 
The British Interplanetary Society 
1933 – 1937 Liverpool

Leslie Johnson wrote this manuscript between 1974 and 1979. It records the BIS story during the Liverpool years. It includes his reflections on their collective 1930’s dream realised in 1969 – the landing on the Moon of Apollo 11. This book (paperback and ebook) includes a foreword from his daughter Pam Reid, an introduction and an epilogue from me. An excerpt from my epilogue is below and “look inside” images of the book, at the bottom.

Most of the early BIS members were writers. Post-war members included Carl Sagan, Eric Burgess, Olaf Stapledon, George Bernard Shaw, Robert Heinlein and Patrick Moore. Clarke, Robert Heinlein, Willy Ley and Isaac Asimov were considered “Astrofuturists”.⁠ They were all scientifically literate, and scientific principles guided their writings. Many of the visions they imagined then underpin our 21st-century society today. For example, the focus of Clarke’s celebrated 1945 paper, ‘Extraterrestrial Relays’, is now deployed in communication satellites that provide communication services anytime, anywhere between anyone on Earth. In 1971, Clarke was invited by the US State Department for the signing of the 80-nation INTELSAT (International Telecommunication Satellite Organisation) agreement. He concluded his speech by saying, “you have just signed far more than just another intergovernmental agreement. You have just signed a first draft of the Articles of Federation of the United States of Earth”.⁠ By chance, in 1975, when he was living in Sri Lanka, Clarke was one of the first to have a private satellite link at home.⁠

In his 1973 novel, Rendezvous with Rama, Clarke imagined a human society living in colonies amongst the solar system’s planets. Rather than a World State, he imagined a United-Nations-like body but for all the colonies of the Solar System. He called it United Planets and based its headquarters on the Moon. Johnson, Cleator, Clarke and all their contemporary writers were innately optimistic and shared principles of Humanism. In October 1939, Cleator described war as the “supreme and ultimate imbecility of the human species”.⁠ Rather than undermining their pre-war naive desire for a utopian future for humanity, their first-hand experiences of war vindicated their belief in a peaceful future for a united human race empowered by spaceflight.
The interplanetary community wrote about a future in which their hopes and wishes of the 1930s would be an everyday reality. A utopian vision where space technology could deliver education, fresh food, medical needs, social interactions and intellectual fulfilment. Much of the imagined technology has arrived, but these benefits are not yet equally distributed to all the people on the planet. That technology allows more people to live longer, healthier lives for the first time in human history. Still, poverty, discrimination and gross inequality persist within and between nations.⁠

An unassuming young man from Liverpool, born in the year the First World War started, Leslie Johnson not only lived through a remarkable period in history but also made a personal contribution to it. As a teenager, he established the Universal Science Circle. He does not write about the thought processes that led him to create it. He did not explicitly express his aspirations for a peaceful world united by a single international language powered by modern technology. But all his contributions convey that vision. It is a vision far from being realised, but incremental progress towards it continues to be made.
