Episode 129: Space Law

By Gurbir Dated: December 18, 2025 Leave a Comment

Professor Kai-Uwe-Schrogl. Cyprus November 2025

Professor Kai-Uwe Schrogl is a space law expert with experience in many roles, including working with the European Space Agency ESA, the German Federal Ministry for Economic Affairs and as the Director of the European Space Policy Institute (ESPI) in Vienna.

In this interview, recorded in Nicosia during cospar2025.org in November 2025, he discusses concerns about the lack of a universally accepted framework for behaviour and governance for the anticipated increase in commercial missions to the lunar surface by nations and companies.

In this discussion, we cover

  • Space law establishes outer space and the Moon as a global common, mandated by the 1967 Outer Space Treaty‘s principles of non-appropriation.
  • Outer space is a global common, like Antarctica, the high sea, and the deep seabed, intentionally protected from national appropriation.
  • Commercial interests and some nations are attempting to undermine the non-appropriation principle to claim resources, especially through lunar mining.
  • The beneficial 1979 Moon Agreement, which enables resource mining through a shared international regime, has not received widespread state ratification.
  • Lack of coordination among numerous state and private lunar missions risks conflicts over attractive sites and complicates the necessary oversight by the state.
  • The urgent need for Space Traffic Management (STM) is highlighted by the threat of Kessler syndrome, caused by growing space debris and mega-constellations.
  • States must harmonise national space licensing regulations to prevent competitive advantages arising from low standards and to avoid the use of flags of convenience.
  • Competing lunar governance approaches, including the Artemis Accords and the International Lunar Research Station (ILRS), demonstrate a lack of unified coordination and early signs that the UN’s Action Team on Lunar Activities Consultation may be the needed, universally agreed governance framework.

Episode 128: George Danos: Cyprus in Space

By Gurbir Dated: December 4, 2025 Leave a Comment

George Danos. President of CSEO

Cyprus is a small country with a small economy with big ambitions in space. George Danos is the president of the Cyprus Space Exploration  Organisation and is considered by some as Cyprus’s Carl Sagan. He has been championing the case for space in Cyprus for years.

In this episode, recorded during Cospar 2025 in Nicosia, he describes the rise of Cyprus’s space activities in communication services, small satellites, collaboration with ESA and more.

  • As President of the Cyprus Space Exploration Organisation (CSO), George Danos has been pivotal in advancing Cyprus’s space programme, particularly regarding international partnerships, infrastructure development, and commercialisation.
  • CSO created spin-off companies, such as Space System Solutions, to promote technology transfer.
  • Cyprus recently achieved Associate Membership status within the European Space Agency (ESA).
  • George Danos spearheaded CSO’s major role in achieving the ESA PECs (Plan for European Cooperating States since around 2016.
  • Establishing the International Space Innovation Centre (CSpark) in Cyprus
  • The first fully integrated Cypriot CubeSat is targeted for readiness by 2026.
  • CSO signed an MOU with Japan’s IHI for new-generation secure maritime communication and India’s Pixxel space, focusing on hyperspectral Earth observation sensors.

Episode 127: Weaving with Graphene. Vivek Koncherry

By Gurbir Dated: November 21, 2025 Leave a Comment

One of the many success stories coming out of the Graphene Engineering and Innovations Centre at the University of Manchester is the story of Dr Vivek Koncherry and his business, Graphene Innovations Manchester. He arrived in Manchester in 2001 to study Textile Technology and completed his undergraduate studies and PhD in Manchester, with his doctoral research sponsored by Bentley Motors.

Dr Vivek Koncherry. His prize-winning design for space habitats

To date, his projects include sustainable cement-free concrete, hydrogen tanks, graphene-based cooling liquid for data centres and space-based human-rated habitats.

Originally from the Indian state of Kerala, he now maintains a global presence, living in Dubai, Saudi Arabia, Miami and Manchester.

Today, his company, Graphene Innovations Manchester, is raising £250 million to devlop industrial-scale plants equipped with AI Robotics and automated weaving machines to coat carbon fibres with nanomaterials continuously. These materials will then be used for real-world applications.

A sort of Back to the Future – a twenty-first-century equivalent of the 18th-century weaving cottage industries that kick-started the industrial revolution in Manchester.

Shenzhou-21: From Launch to space station in 3.5 hours

By Gurbir Dated: November 1, 2025 Leave a Comment

Getting a rocket to dock with an orbiting space station is a huge challenge that requires a deep understanding of celestial mechanics. It is a little (and only a little) like Tom Cruise parachuting from an aircraft onto a moving train. The longer and slower the train, the easier the task. Yesterday’s launch of Shenzhou-21 and docking with the Tiangong Space Station was particularly tricky. A very small train moving extremely fast, but Tom did it!

Yesterday’s launch of Shenzhou-21 carrying a crew of three to the Tiangong Space Station took just over three and a half hours. Previous crewed launches took almost double that, six and a half hours.

Why was it so much quicker? What are the factors that determine the duration between launch and docking and could it be even shorter in the future?

There have now been 16 crewed launches from China’s Shenzhou spacecraft. Shenzhou-5 (15 Oct 2003) to yesterday’s (31 Oct 2025) Shenzhou-21. The first four Shenzhou missions (Shenzhou-1 to Shenzhou-4) were uncrewed test flights designed to validate spacecraft systems, orbital rendezvous, reentry, and recovery.

Typically, these trajectories have taken 1,2, or even 3 days. The concept of a “fast track” trajectory of 6.5 hours was first demonstrated in 2021 with Shenzhou-12.

  • 6 h 30 m with five orbits. A routine first employed in 2021
  • 3 h 30 m with two orbits. First used on yesterday’s Shenzhou-21 
  • 1 h 30 m with one orbit. Not yet used, but theoretically possible

    Why not always use the fast 6.5-hour or faster 3.5-hour trajectories? Surely, the quicker the crew arrive at the space station, the more efficient the mission. Getting a spacecraft from a stationary point on the surface of the Earth to dock with Tiangong at 400km, moving at 7.67 km/s, is a challenge in precision navigation, guidance, and thrust control. The shorter the trajectory, the higher the required precision.

    There are four specific attributes of a safe docking. The shorter the trajectory, the more critical each one becomes

    • Launch Window: Can be as short as a few seconds wide. If missed due to weather or unexpected range activities, a full-day launch delay would ensue.
    • Orbital Insertion: The launch vehicle’s job is to deliver the payload — here, the crew — to the precise orbit within a few meters per second of the calculated orbit. Corrections may involve missing the rendezvous point, requiring an additional earth orbit to correct.
    • Thermal and structural constraints: Short trajectories require rapid orbital manoeuvres and burns, and immediate docking manoeuvres can add unwanted stress to the propulsion system and the crew if manual override is necessary. More complex automated systems are now being deployed with greater confidence.
    • Crew stress and safety: The shorter the trajectory, the greater the demand and stress on the crew to ensure a safe ascent, orbital insertion and docking. Also, should an anomaly occur, there is a narrower window to resolve it.

    With greater testing, built-in redundancy, and higher precision in navigation, guidance and control, the CNSA has developed the required confidence to use these “fast track” trajectories for crewed flights.
