Overview
- Pulsar Fusion said it generated and confined plasma in its Sunbird exhaust test, which it live‑streamed to Amazon’s MARS conference in California.
- The demonstration showed an exhaust channel that uses electric and magnetic fields to steer charged particles, an early building block for a fusion rocket.
- The company claims its Dual Direct Fusion Drive could deliver a specific impulse of 10,000 to 15,000 seconds and about 2 megawatts of electrical power.
- Sunbird is pitched as a reusable space‑tug that would dock with payloads in low‑Earth orbit and push 1,000 to 2,000 kilograms toward Mars in under six months.
- Next steps include performance testing, high‑temperature superconducting magnet upgrades, and fuel‑cycle experiments, with outside validation and orbital docking infrastructure still to be secured.
