T-Minus Space Daily: Europe Makes Moves Towards Reusable Rockets

Podcast: T-Minus Space Daily from N2K Networks
Date: September 30, 2025
Host: Maria Varmazes
Featured Guest: Greg Gillinger, Integrity ISR

Main Theme

This episode centers on Europe’s significant push towards reusable rocket technology, highlighted by major announcements from the International Aeronautical Congress (IAC) in Sydney. Key stories include ESA’s contract with Avio for a reusable upper stage demonstrator, collaborative initiatives in lunar communications, expanding UK space partnerships, and Axiom Space’s advances in astronaut training. The episode also features a detailed orbit analysis with Greg Gillinger, focusing on unusual recent Chinese satellite deployments.

Key Discussion Points and Insights

1. European Space Industry's Strategic Reusability Drive

• Avio’s ESA Contract

  • ESA signs a €43 million contract with Avio for an in-flight demonstration of a reusable upper stage, over 24 months.
  • Goal: Develop a SpaceX-rivaling reusable launch system, culminating in an integrated system preliminary design.
  • Quote (Maria Varmazes, 03:06):

    “This marks a significant step forward in the transition of European launch systems towards full reusability. Yes, they are aiming to develop a system to rival SpaceX.”

• Strategic Vision

  • ESA aims to create high-frequency launchers and an orbital industrial ecosystem, moving away from reliance on the US and supporting a logistics infrastructure in space akin to terrestrial airports and train stations.

2. Major UK and European Collaborative Projects

• UK Space Agency International Bilateral Fund
  • 23 new projects supported by a £6.5 million boost, fostering global partnerships (Australia, Canada, France, Germany, India, Japan, Lithuania, US).
  • Focus Areas: Autonomous 3D printing, lunar agriculture, orbital threat detection, biotech manufacturing, medical research, deep space radar, life sciences, comms, in-orbit servicing, EO, and advanced materials.
  • Quote (Maria Varmazes, 04:34):

    “The UK space funding boost demonstrates the United Kingdom's commitment to international partnerships and a wide range of areas where the space sector can contribute to the UK's economic growth.”

3. Commercial Human Spaceflight and Lunar Economy

• Axiom Space Announcements

  • Emiliano Ventura named first "project astronaut"—a Portuguese physiologist, taking part in a pilot program to optimize astronaut training and study microgravity effects.
  • MOU with Maldives Space Research Organization to establish joint astronaut training programs and spaceflight facilities.

• Telespasio & ispace Collaboration

  • Joint venture for European Moonlight program—developing a lunar communications and navigation satellite constellation.
  • Evaluating ispace’s transport solutions for lunar operations and exploring lunar data and connectivity commercialization.

4. European Satellite Engineering Update

• Beyond Gravity Contract
  • Supplying thruster pointing mechanisms (multi-axis robotic arms) for Swiss Swissto12 HummingSat telecommunications satellites.

5. Yaogan 45: Unusually High Orbit ISR Satellite

• Key Details:

  • Yaogan 45 launched into a highly elliptical orbit (7500km x 206km), later circularized at ~7500km (Medium Earth Orbit).
  • Believed to be an ISR (Intelligence, Surveillance, Reconnaissance) satellite with possible imaging or radar roles.
  • Unique Aspects:
    • High altitude is rare for ISR; challenging Van Allen Belt radiation environment.
    • Large field of view but lower ground resolution compared to low Earth orbit satellites.
  • Quote (Greg Gillinger, 12:36):

    “Having something at 7,500km above the Earth's surface with an imagery mission is interesting… China is unique in that they have imagery satellites in geostationary orbit as well.”

• Potential Reasoning:

  • May leverage heavy shielding for radiation, utilizing the energy/altitude tradeoff for broad area collection and/or alternate mission sets.

6. Xi' an 29: SuperGeo "Weird" Orbit

• Key Details:
  • Launched into "SuperGeo"—an orbit with a period longer than 24hrs, apogee 400km above/nearly parallel to GEO, perigee 14km above GEO, inclination 28.5°.
  • Satellite’s westward drift over 5.5°/day; will circle the globe every 67 days.
  • Purpose Unclear: Released for “space environmental monitoring and experimentation.”
  • Operational Theories:
    • Possibility of inspection/monitoring mission, but high inclination and drift complicate this.
    • Could park over China or continue global drift—behavior will inform future analysis.
  • Quote (Greg Gillinger, 20:34):

    "What I think the term you're looking for is... we call it SuperGeo... anything with a period greater than 24 hours. And Xi' an 29 went out to just such an orbit."

7. Operational Challenges and Observational Limits

• Detection and Targeting:
  • Difficulty in tracking and imaging these satellites due to their unusual orbits and extreme altitudes, both for adversaries and commercial observers.

Notable Quotes & Memorable Moments

• European Self-Reliance Theme:

  “It certainly follows the trend that we are seeing of nations developing their own sovereign capabilities and moving away from their reliance on the United States...”
  —Maria Varmazes, [03:50]

• Orbit Environment Commentary:

  “It's right in the middle of the inner Van Allen belts, which is highly energetic... your electronics need to be hardened for sure.”
  —Greg Gillinger, [14:24]

• Xi' an 29’s Mystery:

  “The purpose of it is unknown as well... does that suggest more of a, some sort of an inspection mission...? It’s just kind of strange.”
  —Greg Gillinger, [22:37]
