Over six weekly ninety-minute sessions online, the course will look at space programmes and missions being conducted by many countries and companies right now.  Starting 10th March 2020. The six sessions will cover

  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. Environmental control in space.  Can the international community apply the lessons of climate change on Earth to the space environment around Earth and beyond?
  5. Militarisation of space. Humans on Earth have always fought on the land, sea and the air. Is war in space inevitable?
  6. Humans in Space.  In this decade, will humans walk on the Moon again? Will this decade deliver, finally the promise of space tourism?

Episode 91 – ISRO and the Spy  who was not


By   Leave a Comment 


Nambi Narayan





One of the most fascinating and colourful characters associated with the Indian Space Programme is Narayan Nambi.    





In 1994, Nambi Narayanan an ISRO aerospace engineer was falsely arrested by the Investigation Beuro on charges of espionage. He was accused of passing on confidential launch vehicle flight test data to foreign nationals. In 1996 he was cleared by the Central Investigations Bureau and India’s Supreme Court found him not guilty in 1998. In 2019 he was presented with India’s third-highest civilian award,  the Padma Bhushan. 





In 1966 he joined ISRO or INCOSPAR as it was known at that time. With the guidance and support of Vikram Sarabhai, he went to study liquid and cryogenic engine technology at Princeton in 1969. He worked on the early stages of the development of the Vikas liquid engine which now powers two of the four stages of the PSLV.





 Some of the topics we discussed include: 





  • During the 1960s he visited the Spadadam site near Carlisle. Today it is a Royal Airforce Station but in the 1960s it was the site used by the British Government test rocket engines and to develop Blue Streak – an Intermediate Range Ballistic Missile. 
  • In 1974 ISRO concluded a barter arrangement – no money changed hands. India would provide 100 man-years trained engineers. 75% of this time would towards supporting France developing their (then new)  Ariane 1 launcher and 25% would be used by India to develop the Vikas Engine with the technology transfer from France. Indian engineers would also build, test and qualify 100,000 pressure transducers for France.
  • He claims to be the architect of this unique barter arrangement.  In addition to being the father and architect of the PSLV.
  • He suspects that the intelligence Beuro picked on him to slow down the Cryogenic engine development and remove him as project director. 
  • Speculating on the why the Vikram lander failed to make a soft landing he thinks it may have been related to the automatic landing sequence (software) or an issue with the braking thrusters.
    He is an advocate of an Asian Space Agency lead by India. 
    He believes China space programme is not ahead of India’s because India has succeeded with the Mars Orbiter Mission.
    He would like India and China to increase collaboration in space.
    In 2017, he published a book on his experiences and a film based on the book will be released in late 2019.

IAC 2019 Washington DC


By   Leave a Comment 


This year’s IAC conference attracted nearly 7000 visitors, exceeding the 6500 in Bremen last years. Two record-breaking years for the IAC in consecutive years. Many astronauts (including Mae Jamison, Charles Bolden, Sergei Krikalev, Oleg Kotov, Sandy Magnus, Jean-François Clervoy, André Kuipers, Buzz Aldrin) were present to commemorate the 50th anniversary of Apollo.





A couple of the themes that caught my eye included





  • Space Situational Awareness (SSA) – The precision (and thus the ability to detect potential collisions) of what is up there and where it exactly is, remains a concern. This will be exasperated with more space assets from emerging nations and the private sector in the coming decade. The mega-constellations will significantly add to the congestion.
  • Satelite Service and refuelling – Lots of new players are developing the early stages of solutions that will prolong the operational lifetime of the spacecraft by providing servicing and refuelling. The use of additive manufacture (3-D printing), automation based on Machine learning and neural networks are already being developed on earth and demonstrated in space.





A bit about the International Astronautical Congress. It was established in 1950 and its governing body, the International Astronautical Federation, in 1951. An annual international congress is held in a different country each year in October.  Last year, IAC was held in Germany, next year it will be in Dubai, Paris in 2021 and Baku in Azerbaijan was announced as the host city for 2022. India, Brazil and Singapore had put in a submission for 2022. 





The current IAF president Jean-Yves Le Gall has come to the end of his term and is handing over to Pascale Ehrenfreund. The IAF has several vice presidents including ISRO’s S. Somanath since 2018. His welcome address for 2019 is below. 





China and Russia had a minimal representation at IAC2019. The programme and the exhibition list entities from China but were absent. It appears that the Chinese delegations were denied US visa at very short notice.
