Episode 73: Using Commercial Of the Shelf (COTs) Components to build spacecraft

By Leave a Comment

If you follow this podcast, you will notice a very long pause since the previous episode. I have been busy writing my second book, the Indian Space Programme which is now finally complete. So I am now back to my familiar but irregular podcasting mode.

The growth in the space sector now widely estimated to be worth annually over 300 billion USD globally. It is primarily being driven by the commercial sector.  The bulk of the expenditure is in satellite television, communication services, Earth observation and businesses enabled by global navigation. In the past, it was technological development driven by the national space programmes that triggered the development of low-cost consumer products. Today it’s the other way round. Sophisticated manufacturing methods and high public demand for digital products have produced low-cost consumer devices which without too much modification can be qualified for use in space. This is particularly true in the sudden growth of the small satellite market.

In this episode, I speak with Dr Rajan Bedi the founder and CEO of Spacechips, a UK based company offering CEO of Spacechips Ltd, which provides industrial R&D and space electronics design consultancy and training services to manufacturers of satellites and spacecraft around the world. I was intrigued by Rajan’s 2017 blog post entitled  “Using and selecting COTS components for space application”. In this episode, I want to understand to what extent spacecraft manufacturers can buy components for spacecraft from the high street.

Episode 67: Technik Museum Speyer

By Leave a Comment

IMG_3306This episode is a preview of some of the space related exhibits in Europe’s largest aerospace museum – Speyer Technik Museum, in Germany. If you ever go and the following may entice you to do so,  four space exhibits to look out for include the following:

Soyuz TM19 – The landing capsule Soyuz TM-19 was used by the German astronaut Ulf Merbold to return to Earth on 4th November 1994 following his launch in Soyuz TM-20 on 3rd October 1994.

Buran – The Soviet Space shuttle Buran was a the Soviet response to the American Space Shuttle. Two complete working vehicles were made.  The Buran was unmanned and, although reusable, was never actually reused. One made a single flight to space and was later destroyed when the hangar housing it collapsed. The other made 25 test flights also unmanned but only in Earth atmosphere.  Following an unexpected find in the Persian Gulf by German journalists, it was brought to Speyer in 2008.

Bor-5 – To assist the Soviets’ design of the Buran they built and flew BOR-5 – a  1:8 scale model of the Buran. Bor-5  made five unmanned sub-orbital test flights between 1984 and 1988.

Moon rock – One of the largest pieces of Moonrock I have seen on public display. It is from Apollo 15 mission but was unveiled at the Museum in June 2013 by Apollo 17 astronaut Gene Cernan. 

If you do go, it is is a big place – one day is not enough!

India and Space

By Leave a Comment

November 21st 2013 marks 50 years of the Indian space program. From humble beginnings devoid of infrastructure, experience or trained engineers, India today has an established track record of designing, building and launching satellites for its own national needs and commercially for others.

The next few podcast offer a glimpse of the people and achievements of this half a century old story .. so far.

Episode 62: An interview with Amrita Shah from the Indian Institute of Science in Bangalore. Author of the most comprehensive biography on Vikram Sarabhai (Vikram Sarabhai :  A Life). Book review of this fascinating book here.

Episode 63: Rakesh Sharma – India’s only spaceman. A video interview recorded in August 2013 where Rakesh Sharma talks about his spaceflight, its aftermath and his views on human spaceflight. Two minute trailer below.

Episode 64 – Bangalore Astronomical Society. Probably the most productive amateur astronomical society in India with a huge presence online and thus an international footprint.

Episode 65 – Professor UR Rao. A look back at the contribution of former ISRO chairman who was originally recruited in to the Indian Space program by Vikram Sarabhai. Whilst working at NASA in the early 1960s, a cosmic ray scientist Rao worked on several Pioneer and Explore spacecraft. Rao was in Dallas waiting to meet Kennedy on that fateful day…

Episode 66 –  Interview with director at the Vikram Sarabhai Space Centre originally known as Thumba Equatorial Rocket Launch Station. TERLS was the site of India’s first rocket launch in to space on 21st November 1963.
