Episode 86 – Moon: Art, Science, Culture

By Gurbir Dated: June 28, 2019 Leave a Comment

Moon: Art, Science, Culture
Moon: Art, Science, Culture

The 50th anniversary of the Apollo 11 landing was a momentous event and expected to be marked by numerous publications. Most books cover the technologies, events, personal recollections and politics of the first human voyage to another world. One book jointly authored by an art historian and an astronomer has a fresh perspective.

The guests in this episode are the authors of the book Moon: Art, Science, Culture – Dr Alexandra Loske Associate Tutor in Art History, University of Sussex and Dr Robert Massey Deputy Executive Director Royal Astronomical Society.

The book is attracting an interesting eclectic mix of readers with an interest in science and art. Some of the topics we spoke about include

  • Fritz Lang’s 1929 sci-fi movie (watch full-length movie on Youtube here) Frau im Mond.
  • The book has a chapter about the Nebra Sky Disk and we also discussed the Antikythera Mechanism.
  • One of the earliest books with a picture of the Moon, called The Moon: Considered as a Planet, a World, and a Satellite  (link offers free download) written in 1874 by James Nasmyth and James Carpenter. Here is an interesting review of it from Dr Stephanie O’Rourke from the University of St Andrews.
  • The Bluedot Festival at Jodrell bank starts on Friday 19th July

Episode 77: Satellite tracking – the early days

By Gurbir Dated: July 13, 2018 Leave a Comment

Sven Grahn has been working in the space field in one way or another for over fifty years. Officially retired, he continues to work as a project leader of a student satellite at the Royal Institute of Technology in Stockholm.

He is perhaps best known for his work in tracking satellites launched by the secretive Soviet Union during the 1960s and 1970s.In those pre-internet days, his work along with others helped to identify individual mission characteristics such as mission types, members of the crew, take off and landing times. He recorded over 1000 conversations from orbiting spacecraft as they flew over Sweden.

In this interview, he speaks about

  • The impact of the space race on his choice of career
  • His work on sounding rockets and meteorology in Sweden and beyond
  • Satellite tracking. What he tracked, heard and recorded using radio and tape recorders.
  • How he came to research and write about the  satellite tracking conducted at Jodrell  Bank radio telescope in England

As an 11-year-old, Sven had seen Sputnik in the sky over Sweden with his own eyes. I started by asking him how the onset of the space race had impacted his choice of career?

Book Review – India’s Rise as a Space Power

By Gurbir Dated: December 24, 2014 Leave a Comment

Title: India’s Rise as a Space PowerIndias Rise as a Space Power
Publisher: Cambridge University Press, India Pvt Ltd
Author: U.R Rao
ISBN-10: 9382993487 ISBN-13: 978-9382993483

In the April of 1971, the USSR approached India and offered to launch an Indian satellite. Vikram Sarabhai asked UR Rao to develop and lead the program. In December 1971 Sarabhai died. Perhaps it was this sacred memory of his mentor, friend and boss that gave Rao the infinite drive to put an Indian built satellite in Earth orbit with remarkable haste.  Where Sarabhai had given India a space program, Rao gave India the confidence to design,  build and operate satellites.  This was the start of Rao’s fascinating career with the Indian Space Research Organisation (ISRO)  that culminated in his decade long tenure as ISROs’ chairman starting in 1984. In this book, Rao recalls his personal recollections whilst at the helm when ISRO started to build and launch science, communication and remote sensing satellites, initiate program for the GSLV 3 heavy launch vehicle and established Antrix, ISROs commercial arm.

The main thrust of the book documents Rao’s key contribution, specifically establishing India’s satellites program and developing  the ground based infrastructure to receive, process and disseminate the resulting data.   It also captures the collaborative, competitive and antagonistic environment of the Cold War that prevailed at the time.

The author shares some remarkable insights that given his central role, have an unquestionable authority.  For example, the Soviet Ambassador Pegov in May 1971 asserted that USSR would only launch India’s first satellite if it was heavier than the first satellite launched by the Chinese (p27).  India was not a just a passive receiver of help from the USSR but as professor Kovtunenko acknowledged India was of “immense value” (p47) to the Soviet space program too. The USSR launched the first three satellites (Aryabhata, Bhaskara 1 & 2) and EAS launched the 4th (Ariane Passenger PayLoad Experiment APPLE).  All were launched without charge. Drawing on his personal international contacts he provided the leadership and the inspiration to make it happen.

In chapter eleven Rao describes his own reservations in the value of accepting the Soviet’s offer to launch an Indian Astronaut. Indian Air Force’s Rakesh Sharma returned from his 8 days in space in April 1984 to huge public celebrations. But ISRO was not ready and could not build on that success at the time.

Most of the 21 chapters in the book deal with the potential of space technology to help mitigate poverty and elaborate on how far that potential has been realised.  Chapter 19 deals with one of the most fascinating episodes in ISRO’s history and Rao was at the centre of it at the time.  India had mastered rockets that used solid propellants and liquid propellants.  ISRO then embarked on a  program to acquire cryogenic engine technology (engines that use liquid Oxygen at -182C and Liquid Hydrogen at -253C) the most efficient rocket engines that exist. The very low operating temperature is a tough engineering challenge. This episode illuminates not only the political upheavals of the early 1990s but also the economics of national space programs.  India had negotiated a cryogenic technology transfer deal with the Soviets but soon after the breakup of the USSR, the USA flexing its muscle as the only superpower forced Russia to renege on the deal. Threatened by the commercial impact of India as a rising space power, USA falsely claimed that the Indo-Soviet technology transfer deal violated the Missile Technology Control Regime.

It is traditional for any book review to include aspects that were not up to scratch even if it ticks all the boxes. A key omission was an index. This is true for any non-fiction book but especially one that deals with key events, people and places. Most of the book uses clear articulate text for which no scientific background is required. However there are small section that are a little heavy e.g “12 C-band transponders provided a 10/12 functional redundancy” (p96). Rao after all is an accomplished cosmic ray scientist with a substantial track record in writing scientific papers.

The author uses the word “parallely” frequently throughout the book.  Initially it was a little repetitive but ultimately this one word conveys the central message that satellite development was not taking place in isolation but several elements of a national infrastructure steeped in science and technology were being harnessed simultaneously for a modern India as the 21st century approached.Sarabhai’s original vision was finally being realised.   

In what is one of the shortest chapters (Chapter 8) Rao describes the birth of the ISRO Satellite Centre (ISAC).  Today ISAC is  where satellites are designed and built before going to Earth orbit or in to deep space. ISAC is a central component of Rao’s extensive legacy and this book authoritatively captures the details of how it came about. The book has an immense value for future historians. Not all previous ISRO chairmen have documented their experiences as Rao has done here.   It is a valuable source of fascinating information in India’s development, an example that future ISRO chairmen should be encouraged to follow.

Episode 68: Stephen H Smith – India’s forgotten rocketeer

By Gurbir Dated: May 6, 2014 2 Comments

On 25th May 2012 the privately funded company, SpaceX used a rocket to transport supplies from the surface of the Earth to the International Space Station 400km above. Although completely incomparable in scope, the first ever delivery of supplies using rocket power took place 77 years earlier in India. The delivery of first aid materials and even the transport of living beings entirely by rocket power was demonstrated by practical experiment in 1935. Now almost forgotten, these experiments were conducted by a Calcutta based Anglo Indian called Stephen Hector Taylor-smith, usually abbreviated to Stephen H. Smith.

Smith launched almost 300 rockets between 1934 and 1945 working mostly unfunded and primarily alone. At 15:35 on April 10th 1935, Smith used a rocket to deliver a parcel containing 12 items including a packet of tea, sugar, spoon, toothbrush and cigarettes about a kilometre across a river. In the aftermath of a devastating earthquake, he illustrated the advantages of rocket powered transport to cover difficult terrain quickly. On 6th June 1935, he successfully launched a  small consignment of first aid material consisting of rolls of bandages, lint, iodine and aspirin over the river Rupnarayan  in west Bengal.

Smith’s 65th rocket launch conducted on the morning of the 29th June 1935 was unique in its cargo and ambition. He demonstrated that living beings and not just inanimate objects could be transported by rockets. In a record making flight, rocket power was used to transport a hen and a cock about 1km across a river. Smith had added stabilising fins, cut almond shaped holes for ventilation and built shock absorbing properties in to the rocket design. The rocket did not employ a parachute, the soft sandy bank was critical and even to Smith’s surprise the hen and cock survived. Both flourished for at least 18 months in a private zoo in Calcutta (today known as  Kolkata).

During the early 20th century, the story of rocket development is told through the cumulative contributions of  iconic names such as Herman Oberth, Wernher von Braun, Sergei Korolev and Robert Goddard. Smith’s contribution cannot be compared to their work but his work was not insignificant and has been mostly forgotten.

Smith was not a trained scientist or engineer. Eventually he tested different types of rocket fuels, fins for attitude control and even designed a rocket to carry a camera to capture aerial images. Initially he was doing not much more than lighting the blue touch-paper of a traditional firework and then standing back. But he was a man of vision and conducted numerous practical experiments to understand and promulgate the potential of rocket power as a mechanism for transport.

Not much is known about his personal life. Smith was born in 1891 in Shillong, Assam. He was an Anglo Indian, a group of people with a European (usually British) lineage and officially recognised in the Indian constitution.  Not much is known about his parents. His father, Charles William Bath Taylor was born in Brigg in the County of Lincolnshire.  His mother, Arabella Martin was the daughter of an English tea planter and probably of mixed heritage.  He attended St Patrick’s Boys School in Asansol in West Bengal, established originally by the Christian Brothers from Southern Ireland.  It was a school for Anglo Indian boys that he joined in 1903, the same year that the Wright brothers successfully demonstrated flight in an aeroplane.

The first aeroplanes to fly in India, did so relatively close to Asansol. On January 6th 1911, during Smith’s final year at school,  more than 750, 000 people gathered at the Calcutta racecourse to witness first hand the magic of man-made flying machines. Smith must have known about the event, he was probably amongst the huge crowd. In the following month, on 18th February 1911 with a formal sanction from the Indian Postal Service, the world’s first official airmail consisting of about 6000 cards and letters was flown from Allahabad to the town of Naini ten kilometres away. It is possible that this experience ignited an interest in aviation, airmail and eventually rockets that stayed with him for the rest of his life.

The First World War had accelerated the development of aviation in the same way that the Second World War did for rocketry. In the early 1920’s, India saw the introduction of aerial transport of cargo, regular airmail and scheduled passenger flights. Smith took an interest in tracking and recording developments in airmail just as steam engine locomotives had attracted enthusiasts in the past and as spaceflight does today.

A global revolution was taking place in ariel transport just when Smith was starting out on his adult life. He had already been involved in Pigeon mail when the potential for airmail arrived. In the early 1930s it was unclear then what form of transport would triumph in the near future airships, aeroplanes or rockets. The first airmail service from Britain to India was conducted by Imperial Airways. The flight left Croydon airport on 30th March 1929 arriving in Karachi on 6th April. On the return flight on the following day, Smith sent a letter to the King at Buckingham Palace in London. The King’s Private Secretary responded on 19th April on behalf of the King “to thank Mr Stephen H. Smith for the letter which he sent to his Majesty by the first flight from India to Great Britain”.

Philately was Smith’s primary preoccupation throughout his adult life. During the 1920s he founded the Calcutta Philatelic Club and the Aero Philatelic Club of India (which changed its name to the Indian Airmail Society on 19th January 1930). Almost all of his rocket launches contained signed souvenir covers and specially designed rocket mail stamps.

For his first trip to Sikkim in April 1935, he sought and was granted permission to print rocket gram stamps in four different colours. Two thousand of each colour were printed. His rocket launches received international press coverage. In July, Smith received a request in writing (via the King of Sikkim) from a Mr A. W. Macintyre from New Jersey in USA. He sought covers from each of Smith’s seven rocket flights.  These flown covers were highly sought after by collectors then and are still today.

In addition to the regular newsletters for the Indian Airmail Society, Smith wrote “Indian Airways”, a work in three volumes detailing the first and special flights within and through India up to March 1930. In 1927, he authored a small book, “The World Flyer’s Danger Zone” covering the hazards of mail flights south east from Calcutta across the Bay of Bengal to Burma and Thailand. He dedicated the book and its proceeds to the widow of Arthur B Elliott who was killed on July 4th 1926. Smith had met Elliott personally in 1925.

By early 1930s rocket mail experiments were being conducted in America, Europe and Australia. Smith was the only one launching rockets in India. He experimented with rockets launches from ship to shore, shore to ship, at night time, across rough terrain and across rivers.

Smith recorded information about his flights, including sketches in his diary and took many pictures. The rockets were launched at a variety of angles, 30, 45 even 80 degrees.  He recorded details of the wind speed and direction and the distance the rocket covered for every launch. He does not appear to have used any instruments to measure altitude, distance or speed so the measurements are likely to have been qualitative rather than quantitative. His largest rocket weighed about 7kg with a total length of around 2m. The payload was typically about half a kilogram but larger rockets were capable of carrying a kilogram.

In February 1936, Smith joined the British Interplanetary Society (BIS) that had been founded in Liverpool three years earlier. He was probably the BIS’s first member from India. The BIS was one of many societies around the world established to promote the development of rocket technology and its application for space travel. Through the BIS’s bulletin and journal which reflected the contribution of its international membership, Smith would have been aware of the technological developments in rocketry worldwide but there is no evidence of how much of what he learnt he put in to practice in his own experiments.

After the start of the Second World War, Smith appears to reduce the details he recorded and published on his rocket experiments. In 1940, he attempted two rocket launches carrying brownie cameras with an intension to take aerial pictures. Neither succeeded. By December 1944, still based in Calcutta, Smith was experimenting with compressed air and compressed gas instead of traditional solid fuel as a means of rocket propulsion.

Despite his pioneering work with rockets he probably did not accomplish his ambitions. He visited the kingdom of Sikkim twice in 1935 to conduct his rocket experiments. On the second time he took his wife and son with him. The king of Sikkim not only supported Smith’s work but actively participated in his experiments by personally igniting some of the rockets. On April 11th 1935, following a successful firing of his rocket number fifty four, a certificate was awarded to him in the presence of the king. This formal recognition was “certifying the utility of the rocket as a means of transport during floods and landslips”. Smith wanted to realise the potential of rocket power for transport for mail and materials just as he was witnessing aeroplanes doing so in his time. His  limited skills and resources prevented him from making significant advances. In 1992, a year after the centenary of his birth the Indian government celebrated his achievements by issuing a stamp and first day cover dedicated to him and his work.

Not much is known of his personal life. After leaving school, Smith worked briefly at the customs department in Calcutta before joining the Calcutta police force as a Round Sergeant on 18th March 1913 on a salary of 100 rupees per month. Whilst with the police, he successfully completed his training as a dentist. His time with the Calcutta police was otherwise uneventful and he resigned on the 4th December 1914. It was as a dentist that he served in the First World War after which he continued in this profession with a private dental practice based at his home address, on 25A Elliot Road in Calcutta.

He married Fay Harcourt in 1918, most probably another Anglo Indian that he had known at least since 1913. They had one son Hector, who did not share his father’s interests. Smith died in 1951 and his wife in 1985 and both are buried in Kolkata. His son Hector married and had a son whose name is not known and daughter, Gloria. The son grew up with learning disability and was sent to an institution. Hector with his wife and daughter Gloria emigrated to Britain. hector died fairly soon after arrival in Britain. Eventually Gloria too got married and had a daughter called Lucy. As Smith’s only living decedent, Lucy may be living somewhere in Britain today.

The following clip is an interview with Mr Melvyn Brown. An anglo Indian who writes on Anglo Indian topics, he lives on Elliot Road in Kolkata, a short walking distance from where Smith lived. He never met Stephen Smith but near the end of this short interviews, he recalls his meeting with Smith’s son Hector.
