ISRO’s Human Spaceflight. Preparing for Gaganyaan. Test Vehicle TV-D1

By Gurbir Dated: October 20, 2023 Leave a Comment

On October 21st 2023, ISRO will conduct an in-flight abort test in preparation for its first human crewed launch in the Gaganyaan mission in 2025.

In this test, ISRO will test the mission abort mechanisms. In an emergency the crew module is separated from the launch vehicle and ejected at high speed to land softly a few kilometres away. These emergency mission aborts can occur at the launch pad or a few minutes after launch.

On 5 July 2018, ISRO conducted a pad abort test. Whilst stationary at the launch pad, the crew module was pulled away to an altitude of about 3 km and safely splashed down less than 5 mins later in the Bay of Bengal.

Today, pad abort and in-flight abort safety systems are an integral part of all crewed spaceflight missions to evacuate the crew in an emergency.

Throughout the more than six decades of human spaceflight, emergency abort mechanisms have been activated three times with human crew involved.

The first incident took place during the Soyuz 7K-T No.39 mission. It was taking a crew of two to the Salyut 4 space station on 5th April 1975. An unsuccessful separation between stage ​two and stage three compromised the mission. The Soyuz activated the abort sequence separating the crew module from the launch vehicle. Twenty minutes after launch the crew landed safely in the USSR on a snow covered hill side close to the Chinese border.

The second one was observed live by Rakesh Sharma in real-time, six months before his own flight. On 26 September 1983 Gennady Strekalov, the flight engineer and his commander Vladimir Titov survived the fire that broke out moments before the launch of Soyuz T-10-1. The built-in safety pad abort mechanism activated separating the crew module from the launch vehicle. The crew module landed safely 4 km aways. Rakesh Sharma and Ravish Malhotra watched the drama play out live. Six month later Rakesh Sharma sitting next to Gennady Strekalov launched on Soyuz-T-11 to Salyut-7 for his week long stay in space.

The third incident took place on 11 October 2018 when Soyuz M10 experienced a booster separation issue a few minutes after launch. It meant that NASA astronaut Nick Hague and Russian cosmonaut Aleksey Ovchinin would not be able to reach their destination, the ISS. An abort was initiated, the crew capsule separated from the launch vehicle and landed safely about 20 minutes after launch.

All three instances saved lives. No lives have been lost in space but several on the journey to or during the return. All the crew on two space shuttles (Challenger 1986 and Columbia 2003) were lost. The Space Shuttle design did not incorporate a similar abort mechanism. This is the scenario being tested by ISRO on 21st October 2023.

Why India signed the USA’s Artemis Accords and why now?

By Gurbir Dated: September 22, 2023 Leave a Comment

First published in the Autumn 2023 edition of Room. Space Journal of Asgardia.

Updated 23rd September 2023 – Astrotalkuk.org Read full text online below or download pdf here.


During India’s Prime Minister Modi’s 4-day visit to the USA from 20th to 24th June 2023, India signed the Artemis Accords. Why did India do that, what was in it for the USA and why did it happen then?

The Artemis Accords is a non-binding bilateral agreement (thus not international law) between the USA (NASA and the USA State Department) and each nation that signs up. It specifies 10 principles, ostensibly consistent with the United Nation’s 1967 Outer Space Treaty (OST), for international cooperation in the civil exploration of the Moon, Mars, Comets and Asteroids. It was announced on 13th October 2020 during the 71st International Astronautical Congress in Dubai. The initial number of 10 countries (Australia, Canada, Italy, Japan, Luxembourg, the United Arab Emirates, the United Kingdom and the United States) has gradually grown since. On 22nd June 2023, India made it to 27 countries. Since then Argentina and Germany have signed bringing the total to 29.

Why did India sign when it did? The technologies for commercial exploitation of resources on the Moon and other celestial bodies is now sufficiently mature that every nation that can is rushing headlong to get their stake in the ground. The Moon has a very large deposits of many commercially sought after materials substances for example Helium-3 and Lithium. The technology to mine, refine and transport back to Earth is not yet present. But when it arrives, those nations with a presence on the Moon will be ready.

Indian Ambassador Taranjit Sandhu, signs the Artemis Accords on 21 June, 2023. US Department of State Deputy Assistant Secretary for India, Nancy Jackson (left), NASA Administrator Bill Nelson, and ISRO Space Counsellor, Krunal Joshi.

The number of missions beyond Earth’s orbit, especially to the lunar surface is expected to dramatically increase in this decade. Out of the six lunar landings scheduled in 2023, so far Japan’s (Hakuto-R) failed in April, Russia’s Luna 25 was lost in August. India succeeded with its first soft landing with Chandrayaan-3 on 23rd August 2023. Another from Japan (SLIM), and two NASA commissioned, private sector missions (Nova-C IM-1 and Peregrine) could land before the end of 2023.

As more companies and countries gain a foothold on the Moon, they will benefit from an agreed set of common rules. That is where the Accords come in. The Accords require all countries that sign to abide by a number of principles when operating in space beyond the Earth. The 10 principles include:

1. Peaceful uses: cooperative activities are exclusively for peaceful purposes and in accordance with international law.

2. Transparency: commit to broad dissemination of information regarding their national policies and exploration plans. Agree to share scientific information with the public on a good-faith basis consistent with Article XI of the OST.

3. Interoperability: agree to develop infrastructure to common standards for space hardware and operating procedures that include fuel storage, landing systems, communication, power and docking systems.

4. Emergency Assistance: commit to offering all reasonable efforts to render assistance and comply with the rescue and return agreement as outlined in the OST.

5. Registration of Objects: agree to register and publicly establish which space objects, (on the surface, in orbit or in space) are owned and operated by who.

6: Release of Scientific data: commit to openly sharing scientific data arising from space exploration missions. Not mandatory for private-sector operations.

7. Preserving Outer Space Heritage: undertake to ensure new activities help preserve and do not undermine space heritage sites of historical significance.

8. Space Resources: signatories affirm that extraction of resources does not inherently constitute national appropriation under Article II of the OST.

9. Deconfliction of Space Activities: undertake exploration with due consideration to the UN guidelines for the long-term sustainability of Outer Space Activities as adopted by United Nations Committee for Peaceful Uses of Outer Space (COPUOS) in 2019. Activities, where potential harmful interference could occur, should be restricted to pre-identified Safety Zones. The size, location and nature of operations in a Safety Zone should be notified to all signatories and the UN Secretary-General.

10 Orbital Debris: signatories agree to limit harmful debris in orbit through mission planning that includes selecting flight orbital profiles that minimise conjunction risk, minimising debris release during the operational phase, timely passivation and end-of-life disposal.

The current and next decade will see multiple nations arriving at the Moon, near-Earth asteroids and comets for space exploration and commercial exploitation. The accords define a set of guidelines, principles, and a set of common norms and behaviours that are mutually beneficial when operating missions far from Earth. But why not simply sign up for the United Nations Outer Space Treaty and the Moon Treaty? Whilst the Outer Space Treaty, established in 1967 has 113 signatories, The Moon Treaty (1979), only 18 parties have agreed to be bound by it. India is one of those 18 but has not yet ratified.

Why have so few nations signed up to the Moon Treaty? All to do with the legal status of extracting resources from the Moon. Article I of the OST describes outer space which includes the Moon and other celestial objects as being the “province of all mankind” and “is not subject to national appropriation”. Further, article II in the Moon Treaty explicitly forbids any part of the Moon from becoming the property of a nation, a private organisation or a person. Countries don’t sign up to the OST because they consider it will restrict their future potential commercial operations in space and especially on the lunar surface. The Artemis Accords, on the face of it, offer a workaround. All member nations affirm that extraction of resources “does not inherently constitute national appropriation under Article II of the OST.” In other words, you can extract and own the resources but have no claim of ownership of the place from which they came. How legally robust that is, only time will tell. The Artemis Accords (now with 29) already has more signatories than the Moon Treaty (with 18).

But there is another reason why nations may join the Artemis Accords. As the name suggests, The Artemis Accord signatories get to join the already International “Artemis Programme”. What that actually means will depend on the capability each nation can bring to the table. Even a small nation, new entrants like Romania and Rwanda with minimal capability will have access to and opportunities for cooperation. A key benefit of any club membership is access to other members of that club.

Why has India joined only now? Artemis Accords has a competitor. Less than a year after the Artemis Accords were announced, China and Russia established the International Lunar Research Station. The ILRS is a lunar base designed for conducting scientific research. It includes all the support facilities on the lunar surface, in lunar orbit and transport between Earth and the Moon. Two years on, only four nations have joined (Pakistan, the United Arab Emirates, South Africa and Venezuela) China and Russia.

India has always remained non-aligned. It has kept its options opened and lipped between USSR, Europe or the USA – wherever its interests were best served at the time. A lesson learnt during the international sanctions regime following India’s nuclear tests in 1974 and 1998. India’s first rocket launched into space in 1963 came from the USA. Its first satellite and first astronaut went to Earth orbit on USSR launch vehicles. India used the Space Shuttle to launch one of its communication satellites in 1983, collaborated with NASA on its first Moon mission in 2007 and is preparing to launch a joint ISRO/NASA Earth observation in 2023. ISRO has launched European satellites and engaged the European Ariane 5 to launch its heavy GEO satellites. Over the last 5 years, Russia has been assisting ISRO with its Gaganyaan (Human Spaceflight) programme.

Sanctions imposed on Russia following its invasion of Ukraine have severely diminished its ability to collaborate in space. Right now and in the foreseeable future, India sees more opportunities with the USA than with Russia.

The geopolitical and economic landscape of mid-2023 was just right for the USA to invite India and India to accept. It was in USA’s interest to get India onboard. It is a win-win situation. As a result, India will have access to technology and know-how for its upcoming high priority Human Spaceflight Programme, Gaganyaan. For the USA, India joining is a huge boost for the Accords which will motivate more countries to join the Accords rather than the ILRS. Setting the Accords on the road to becoming the de facto standard.

The principles of the Accords are said to be “grounded” in the OST and the Moon Agreement, but the Accords is not a United Nations product but has its origins in the USA State Department and NASA. If and when France and Italy sign-up, the Accords will become the default go-to framework for international collaboration in space. In the process, pretty much side-lined the ILRS. A geopolitical win for the USA.

Recognising the importance of India signing the accords, India extracted significant concessions that included space and non-space-related benefits. Although diplomatic ambiguity obscures any direct connection to the significant concessions.

Additional USA-India agreements announced at the same time include :

a NASA/ISRO joint mission to the ISS in 2024 (this tight timeline may not be met but more immediately this may ‘facilitate” NASA support for India’s Gaganyaan programme)

 support India’s membership of the Mineral Security Partnership

establish a joint Indo-US mechanism between industry, government and academia for artificial intelligence, information science and quantum information.

A new public-private cooperation forum for the development of advanced communication using 5G and 6G.

A multimillion-dollar investment to establish a semiconductor ecosystem which will include semiconductor assembly and test facilities in India.

In addition to collaborative activities in space, and bilateral economic opportunities, perhaps the most significant concession was the 4 days state visit by India’s prime minister to the USA and the opportunity to address a joint meeting of the US Congress. A public endorsement from the president of the most powerful democracy to the prime minister of the largest one. Particularly useful for a prime minister looking to win a 3rd term in elections in India in 2024. In return, the USA, through India’s membership, boosted the future success of the Artemis Accords and the Artemis Programme.

However, the Artemis Accords are not legally binding. It is not a treaty or an agreement but a set of Accords. There is no compliance or enforcement mechanism. Despite it being a product with roots in one country, currently, it is the only framework that can offer practical value and tangible benefits to all nations with space missions beyond the Earth.

In the USA, the Wolf Amendment legally restricts how NASA can collaborate with Chinese Space missions. Whilst the Wolf Amendment does not legally prohibit China from signing the Accords, in practice that is the effective outcome. Over the last decade, China checked off some astonishing accomplishments in space. Highly successful human space programme, a space station in Earth orbit, a Lunar rover on the far side of the Moon and a soft landing of a rover on the surface of Mars. China sees the Artemis Accords as an instrument to sustain US dominance whilst undermining China’s space ambitions. All this whilst Russia’s space programme has experienced a significant decline resulting from the sanctions following its invasion of Ukraine. Russia may be associated with the heady days of Sputnik and Gagarin but now China has surpassed Russia and is second only to the USA. Whilst the Wolf Amendment remains, it is unlikely in the short term that China will join and thus prevent the Artemis Accords from being adopted as a near-global framework for responsible behaviours in space.

Just as in Star Trek, the Khitomer Accords of 2293 were followed by the Second Khitomer Accords in 2375. So as the Artemis Accords attain wider engagement, they will evolve over time too.

That the Artemis Accords is a product of one country, the USA is its major drawback. To succeed in its ambition to be a global “common set of principles to govern the exploration and use of space” the Artemis Accords require an internationally inclusive appeal. In a decade or two when the Artemis programme exists only in the rear-view mirror of space history, the Artemis Accords could finally become the global governance framework for all nations exploring and exploiting space beyond Earth orbit. The content could remain substantially unchanged but politically transformed with a new name and placed under the auspices of the United Nations.

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


Gagarin and British PM McMillan

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.
