Franklin Chang Diaz to test Full Scale VASIMIR
Testing a full scale ground prototype next January. Follow o plans to have a flight model raise ISS's orbit. Good luck to the bro at Ad Astra (US & Costa Rica)!
Sadly this MIR Review article wastes print on inane questions about Why Space? instead of more detailed information on VASIMIR that would be appropriate and expected.
