Using power beamed from low earth orbit, a Myrabo Lightship climbs towards the edge of space. NASA Myrabo Lightship climbs towards low Earth orbit by means of beamed power and the use of airspike technology. NASA ing plasma energy directly beneath the craft, allowing it to attain a speed of about 50- 100mph (80-160km/h). As the Lightship begins to climb, the con- trolling system will interface with the nearest Powersat, requesting a tight microwave beam of 4-5 gigawatts. When the beam illu- minates the vehicle, antennas (called recten- nas) located within the upper shell of the Lightcraft re-direct this energy just beyond the rim of the saucer. In turn, this generates a significantly more intense field of plasma beneath the craft, which is regulated and shaped by superconducting magnets encir- cling the craft. 170 Secret Projects: Flying Saucer Aircraft
