This project aims to decelerate space vehicles by applying a magnetic field to the hot ionised gases that form around the vehicle. In the thin atmosphere of Mars, aerodynamic drag alone is not enough to land a spacecraft larger than 1 tonne. A human mission to Mars requires landing of payloads up to 80 tonnes. Interaction of the magnetic field with the ionised flow dissipates kinetic energy and can reduce surface heating. This project could make Mars-return missions feasible by enabling greatly increased payloads. It also aims to evaluate magnetohydrodynamic braking and heat mitigation at true flight conditions.

该项目旨在通过向航天器周围形成的热电离气体施加磁场来使航天器减速。在火星稀薄的大气层中，单靠空气动力学阻力不足以使一个超过1吨的航天器着陆。人类的火星使命需要80吨的有效载荷着陆。磁场与电离流的相互作用消耗动能，并可减少表面加热。该项目可以通过大大增加有效载荷使火星返回任务变得可行。它还旨在评估真实飞行条件下的磁流体动力制动和热缓解。
