Episode 91 – ISRO and the Spy who was not

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.

Episode 88 – India’s Private Space Sector

By Gurbir Leave a Comment

No country has exploited space for social and economic benefits more than India. It has always been a government-run operation, until now.

As in other nations, the private space sector is emerging in India. One name that pops up when discussing private and commercial space in India is Narayanan Prasad. He has been instrumental in forging platforms where all stakeholders from the New Space Community can support each other and share views, opinions and news. The platforms include Whatsapp, Blog, Telegram and a New Space India Podcast.

In this episode, he recalls his journey so far and his part in his own start-up Satsearch.co as its COO. Here are some of the key takeaways from this interview

Most private sector players build products designed by ISRO under licence from ISRO. Private Space Sector in India is subject to excessive government bureaucracy preventing engagement from private investigators.
An independent regulator is needed. Independent regulator in telecommunication opened up the market for private telephone lines. An independent regulator for the private space sector is essential for this market to flourish.
NASA has created the Commercial Lunar Payload Service (CLPS) to engage the private space sector companies. India does not have anything equivalent.
This year ISRO established the New Space India Limited (NSIL). It was established to limit the potential impact of the Antrix/Devas case.
Policies exist in India for Communication and Remote Sensing but no overall policy for Space – yet. Although a draft Space bill was published in 2017 for comment. That bill drew a distinction between companies that work with ISRO and those outside ISRO.
Two of many space startups in India include
- Bellatrix Aerospace produces Ion engines for in-orbit spacecraft propulsion. Ion propulsion and reduce the spacecraft weight and extend the operational lifetime by about 60%
- NoPo technologies are the only producer of Carbon Nanotubes in India. Like Graphene, Carbon Nanotube is an allotrope of Carbon. The unique properties include high tensile strength, electric and thermal conductivities.
Satsearch.co – now 3.5 years old based in the Netherlands and managed by a distributed team based in Germany, Netherlands, Italy and England. Had it been based in India – it may have been subject to restrictions e.g queries coming in from Suparco in Pakistan.
As with any new emerging industry – most of the current space startups will cease to exist within 5-7 years from now.

Space Museum at BM Birla Science Centre. Hyderabad

By Gurbir Leave a Comment

On 26 July 2019, India’s first public space museum opened its doors in Hyderabad. With support from ISRO, the 9000 sq ft is now devoted to pictures, models and stories about India’s space programme.

Billed as India’s first space museum but that title really goes to the VSSC Space Museum housed in St Mary Magdalene Church, in Thumba. It was the headquarters of was then known as INCOSPAR and became ISRO in 1969. This Church museum is located inside the sprawling Vikram Sarabhai Space Centre, an operational ISRO site, so access to it is restricted and must be booked in advance.

The initial 24 exhibits in this new space museum include scale models of Indian Launch vehicles GSLV Mark III, GSLV Mark II and PSLV, Chandrayaan-1, Mars Orbiter spacecraft, APPLE, Aryabhata, Bhaskara, Rohini RS-1 and a model of the International Space Station.

The exhibits were collected over two years by the curator, Pranav Sharma. Sharma who is an engineer, a scientist, a TedX speaker and a science communicator has put together an attractive set of exhibits to inform, educate and entertain visitors of all ages about India’s space programme. This rich eclectic collection of exhibits includes lines from William Shakespeare, Dillon Thomas and even lyrics from a Coldplay track.

The new Space Museum inside the Birla Science Centre is open to the public and is first of a series that will be set up around India in the coming years. The museum doe not really have a website, other than this and the Birla Science Centre website does not give any prominence to this new resource. Despite the numerous compelling exhibits, the space museum lacks tactile and interactive exhibits that especially children are so fond of handling and engaging with.

Sharma offers a taste of the experience in this 40-minute youtube video, an online tour of the museum and invites visitors to come and visit in person.

Dr David Baker has been involved with the USA since childhood. First attending a US school in England and then studying in the US under a scholarship program sponsored by Senator Clinton P Anderson. He returned to the USA and worked for NASA on various programs from Gemini to the SpaceShuttle. After leaving NASA, he set up one of the earliest private space sector companies in London.

Today he is the editor of the British Interplanetary Society’s monthly journal – Spaceflight and a prolific author of space books. Some of the topics we spoke about include

Early interest in space and astronomy stimulated by milestones such as breaking of the sound barrier, Sputnik and Gagarin’s flight.
Completed his PhD in Earth and Planetary physics.
Worked for Nasa between 1965 and 1984. Mainly in the mission
Setup a consultancy in 1984 to bring US launch and satellites services to the wider international community.
Setup a consultancy in 1984 to bring US launch and satellites services to the wider international community
Delayed the launch of STS-41B in February 1984 carrying payloads for Indonesia and Western Union but problems with the payload Assist Modules did not meet the insurance certification requirements.
