Satellites powered by solid metal could one day use space junk for fuel

illuminem summarises for you the essential news of the day. Read the full piece on CNN or enjoy below:

🗞️ 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
