🗞️ Driving the news: British startup Magdrive is developing a revolutionary satellite propulsion system that could be powered by solid metal, potentially using space junk as fuel in the future
• The system, set to launch its first prototype in June 2025, aims to be 10 times more maneuverable and 10 times smaller than current options
• If successful, it could enhance satellite mobility while addressing the growing issue of orbital debris
🔭 The context: Currently, satellites rely on chemical or electric propulsion, each with limitations in thrust and efficiency
• Magdrive’s system uses ionized solid metal, offering high thrust with improved fuel efficiency and storage benefits
• However, using space junk as fuel remains hypothetical due to legal and technical challenges, including ownership laws and contamination risks
🌍 Why it matters for the planet: Space debris poses a growing threat to satellites, space stations, and future missions
• A propulsion system that can utilise existing debris as fuel could help reduce the amount of junk in orbit, making space activities more sustainable
• Magdrive’s approach also minimises reliance on hazardous chemical propellants, reducing potential environmental risks
⏭️ What's next: Magdrive plans to launch its Warlock propulsion system in June 2025, followed by commercial deployment in 2026
• Further advancements are needed to make refuelling from space junk viable, requiring regulatory approvals and technological breakthroughs
• The company is also working on a refuelable version of its system, which could significantly extend satellite lifespans
💬 One quote: “We wanted to build something that really moved the needle for humanity in the space industry.” — Mark Stokes, co-founder of Magdrive
📈 One stat: Over 13,000 satellites remain in Earth’s orbit, with around 20% inactive, contributing to the growing space junk problem
