Lithium-Powered Thruster Sets US Record, Advancing Crewed Mars Missions

NASA’s next‑gen electric propulsion thruster using lithium metal vapor set a US power record at 120 kilowatts, signaling major progress toward fuel‑efficient, long‑duration missions to Mars. While such systems could drastically cut propellant needs and enable faster transit, a crewed Mars mission would still demand multi‑megawatt power and thousands of hours of operation to manage cruise and surface phases, underscoring both promise and engineering challenges for future deep‑space travel.

Swiss Students Test 20,000-Detonation-Per-Second Rotating Rocket Engine

A team of ETH Zurich students from the ARIS Pegasus project tested a rotating detonation rocket engine powered by propane and liquid oxygen, achieving stable detonation waves at up to 20,000 per second in a nighttime test at Dübendorf Air Base. The milestone underscores growing international interest in rotating detonation propulsion, which could improve fuel efficiency and payload capacity for future space missions, though it demands advanced materials and ultra-fast fuel injection. The project highlights collaborative, iterative student research and places Switzerland among a small group pursuing RDRE demonstrations.

NASA tests lithium-metal electric thruster, hits 120 kW power in breakthrough propulsion demo

NASA’s Jet Propulsion Laboratory demonstrated a lithium-metal vapor electric thruster and set a 120 kW power record, marking a major step toward high‑power, fuel‑efficient propulsion for future crewed Mars missions. While the tech promises substantial propellant savings, a real Mars mission would require multi‑megawatt power and thousands of hours of operation to enable transit, landing, and return; scaling the system remains the key challenge.

Laser-Propelled Metajets Could Shorten Alpha Centauri Trip to 20 Years

Texas A&M researchers demonstrated micron-scale metajets that use metasurfaces to move in three dimensions when illuminated by laser light, enabling 3D maneuverability that could, in theory, scale to propel larger craft. While the approach could cut a trip to Alpha Centauri to about 20 years, feasibility remains uncertain as tests to date occurred in fluid environments and microgravity space tests are planned to validate practicality and scaling.

Astrobotic’s Chakram RDRE Delivers 4,000+ Lbf Thrust in NASA Hot-Fire Demo

Astrobotic tested its Chakram rotating detonation rocket engine at NASA’s Marshall Space Flight Center, firing two prototypes to more than 4,000 pounds of thrust per engine for a combined 470 seconds of burn time across eight hot-fire tests, with no damage observed. The RDRE uses detonation shockwaves in a circular channel to boost efficiency and has potential for lunar landers and deep-space propulsion, supported by NASA SBIR awards and a Space Act Agreement; similar RDRE work is underway by Venus Aerospace and NASA.
