Cool!
Since air becomes ionized, and by definition charged, during re-entry, the Russians are looking at using a magnetic heat shield as an adjunct to physical heat resisting techniques.
Cool!Basically, by generating a magnetic field, it can deflect the hotter air away from the spacecraft:
The flight test would use a Russian Volna rocket, which is able to launch a 650kg (1,430lb) payload. The Volan capsule will be the payload for the flight test. It will re-enter the atmosphere at up to Mach 21, and design work is under way to fit the super conducting coil system within its internal volume.
Other issues to be tackled include the ability of the coil to withstand the launch and flight environment; trajectory modification to compensate for the increased drag caused by the atmospheric gas deflection; and telemetry data recovery, when radio signal blocking ionised gases form around the vehicle.
