The idea of using rockets for transport had been well-established before the first flights of heavier-than-air aeroplanes in 1903. When it comes to turning that idea into reality, three names are considered as fathers of rocketry: Konstantin Tsiolkovsky, Robert Goddard and Hermann Oberth.

For this episode, I visited the Hermann Oberth Space Travel Museum in the German Town of Feucht, near Nurnberg and spoke with its director Karl-Heinz Rohrwild. A summary of the interview is below along with some pictures from the museum.

The museum is run entirely by volunteers in the interest of science. The exhibits on display are a tiny amount of the exhibits that exist. Museum expansion planned the for 100th of the publication of his second book in 1929. With plans to make lots of the documents available online.I found Karl-Heinz very helpful, opening the museum for my visit during a public holiday. He and his colleagues extend that welcome to anyone wishing to visit. Contact details here.

Summary

  • His father had been a surgeon. He wanted Hermann to have a career in Medicine.
  • Brilliant at maths but likely he was autistic at some level.
  • Lost his brother Adolf in WW1 and became anit-war.
  • Considered using a massive bomb delivered by rocket to destroy the senior people who decided to start and maintain the war.
  • Wrote two key books in rocketry in the 1920s
  • Fritz Lang director of the early sci-fi Metropolis followed by Frau im Mond. Oberth worked on that film as an advisor.
  • 1929: Winner of the International Award for Astronautics (Robert Esnault-Pelterie-Hirsch-Award)
  • Envisaged the use of solar energy in orbit and designed the first gyroscopes.
  • Also envisaged a huge space-based mirror that would beam power down to Earth for terrestrial use.
  • 1927 A member of the first and most successful space/rocketry society – Verien for Rsumshifffhart (Society of Space Travel)
  • Oberth championed the use of rocket staging, liquid engine propulsion and the use of rocket engines in the near vicinity of space (not in the atmosphere)
  • The RAF bombing raid on August 26, 1943, nearly killed both Oberth and Wernher von Oberth were working there.
  • Post WW2 interrogated by Theodore von Karman and it was decided Oberth was not taken to the USA. In part, Oberth did not want to go.

The day the Cosmonaut came to Manchester

By Gurbir Dated: April 28, 2023 Leave a Comment

This piece was first published in Manchester Histories blog on 12 April 2023

On Wednesday, 12th April 1961, a bright and sunny spring morning, an air force pilot of the USSR launched into space using a modified intercontinental ballistic missile. On his first trip outside the USSR,  Yuri Gagarin, aged 27 went -around the world in just 90 minutes. He broke the world altitude and speed records. He was the first to experience the realm and sensation of being in space. Exactly three months later, he came to Manchester.

He arrived at Ringway airport at around 10am on Wednesday, 12th July and travelled first to the Headquarters of his hosts, the Amalgamated Union of Foundry Workers (AUFW) in Old Trafford. It was a sunny day but peppered with occasional sharp showers typical in July. Thousands lined his route from Ringway to Old Trafford.  Travelling in an open-top Bently, he received a true Mancunian welcome. He was soaked. In the small union HQ, he was made an honorary member of the AUFW and President Fred Hollingsworth presented him with a medal engraved with the words “Together, moulding a better future”. 

His second stop was Metropolitan Vickers in Trafford Park, a unique place in Machester’s history of the industrial revolution. By now, the rain had stopped but puddles hinted at the recent downpour. Stanely Nelson recalled shaking Gagarin’s hand near the foundry. He recalled the working conditions most foundry workers endured saying, “it was like a vision of hell. Smoke, fire and tiny thin men silhouetted against the foundry fire. No one was fat; they were all thin like Lowry’s match stick men”. Of all his time in Britain, it was this time surrounded by working men and women amongst the dirt and grime of a working foundry that Gagarin would later say he felt most at home.

He arrived at Manchester Town Hall for a formal civic reception hosted by the Lord Mayor. Albert Square and all the surrounding office windows and doorways were crammed with people waiting to see the only man with the experience of Earth orbit. The dignitaries who got to shake his hand included Bernard Lovell from Jodrell Bank and the mathematician Kathleen Ollerenshaw. At the Town Hall, Gagarin, speaking in Russian, expressed his wishes for future space missions saying, ”I would like naturally like to fly to the Moon then perhaps to Mars and Venus and even further if my abilities make it possible”. By 16:30, he was at Ringway on his flight back to London, where he had arrived the day before and would stay until his return flight to Moscow on Saturday, 15th July. 

His spaceflight was packed with risk. He had left his wife a letter saying that should he not return, a real possibility, she should not remain alone. He experienced problems at launch and another during re-entry. The service module separation did not go to plan. The mission and his life came close to a catastrophic end. Ejecting from his spacecraft and landing separately by parachute, he returned to Earth as a real-life superhero. It was a supreme technological triumph, fulfilling humanity’s age-old dream of leaving Earth. It was achieved by a nation championing the virtues of communism in the midst of the Cold War. This was his first visit to the heart of the democratic West to demonstrate the prowess of the communist way of life.

To avoid highlighting the USA’s failure (its ally) to “be the first”, the UK government could not offer Gagarin a formal invitation. The remarkable response on his first day in London on 11th July, the public turned out in their thousands lining the streets in London and inundating Earls Court, the venue of the Soviet Trade Fair. Before the day was out, he had received an invitation from the Prime Minister, Harold Macmillan and the Queen. His initial two-or-three-day UK visit was extended to five.

Following the global coverage of his flight in April, AUFW President Fred Hollingsworth discovered that Gagarin had trained as a Foundry Worker. It was the invitation the AUFW made in May of 1961 that brought Gagarin to Manchester.  Gagarin met the Prime Minister at the Admiralty and the Queen in Buckingham Palace, along with other visits to the Air Ministry, Mansion House and the Royal Society at Burlington House. In April 1962, the first anniversary of his flight, Gagarin sent a message to the people of Manchester saying, “And the firm handshakes of my fellow workers in the moulding shop were dearer to me than many awards”. For the many who saw or met Gagarin recalled his charm, good looks and his persistent smile.

Gagarin’s visit coincided with the heightened risk of another world war. The Bay of Pigs invasion, the end of the ban on nuclear weapons testing, the building of the Berlin Wall and the Cuban Missile Crisis. He was probably aware of the rising geopolitical tensions more than most. While in Manchester and London, Gagarin repeated his message of peace. Despite his extraordinary achievement, the people of Manchester saw an ordinary man with humble roots. For most, he was probably the only individual from the USSR they would ever meet.

Episode 109 – The Antikythera Mechanism with Prof Xenophon Moussas

By Gurbir Dated: December 16, 2022 Leave a Comment

I first came across the Antikythera Mechanism just over a decade ago. It is still the most incredible artefact from history. It is as out of place in our time as William Shakespeare using an Iphone or Vasco De Gama travelling in a speedboat.

The Antikythera Mechanism is a complex mechanical (clockwork) device that can determine the position of the planets and phases of the Moon and predict when solar and lunar eclipses will occur. Constructed about two thousand years ago, it was discovered in 1901.

The three calendaric machines, made of wooden gears, from around 1780 in the National Museum of Iceland in Reykjavik. They are grandchildren of the Antikythera Mechanism. References to Cicero’s text to the Antikythera are available here.

Perhaps the most recent and informative video by published by mathematician Tony Freeth is available on Youtube. A paper published by several active researchers, including Tony Freeth, was published in Nature. Investigation continues today. Underwater research continues today at the shipwreck site. Press release from June 2022. This interview was recorded in July 2022 in Athens during Cospar 2022.

Athens-based Professor Xenophon Moussas has been mesmerised by it since childhood. As a mathematician and a space scientist, he has been involved in using leading technology to reveal its mysteries. He is available for presentations on the Antikythera Mechanism and can be contacted via email xmoussas AT gmail.com.

Episode 104 – William Leitch. The forgotten Scottish Rocket Pioneer

By Gurbir Dated: October 28, 2022 Leave a Comment

When it comes to the pioneers of rocketry, tradition has it that it was Tsilokosky, Goddard and Oberth. in this episode, author Rob Godwin talks about William Leitch from Scotland. Leitch was writing about the principles of rocket propulsion and space travel in 1861. Decades before Tsiolkovsy. Over the last few years, Rob has been researching Leitch’s story and published a book – William Leitch Presbyterian Scientist & The Concept of Rocket Space Flight 1854-1864

In this interview recorded via Zoom, Rob Godwin recalls how he came across Leitch’s work and the research activity that eventually led him to uncover this remarkable story.

The following 19th-century publications, that Rob refers to are now available online, and pdf versions can be downloaded. Links are available on the episode page
