1 00:00:00,550 --> 00:00:05,230 My name is Dave Manzella, I’m the Chief Engineer for the Solar Electric Propulsion 2 00:00:05,230 --> 00:00:09,610 Program at NASA Glenn. 3 00:00:09,610 --> 00:00:18,369 Music The Solar Electric Propulsion Program is a 4 00:00:18,369 --> 00:00:23,519 program we’re developing next generation space propulsion technologies that could one 5 00:00:23,519 --> 00:00:25,740 day be used to send men to Mars. 6 00:00:25,740 --> 00:00:30,399 Right now were working to develop systems that could be operated at about 50 kilowatts 7 00:00:30,399 --> 00:00:31,529 of electrical power. 8 00:00:31,529 --> 00:00:37,480 That’s about 5 to 10 times greater than the power level that are currently being used. 9 00:00:37,480 --> 00:00:43,780 The work that we’re doing would be used to send cargo and payload logistics resupply, 10 00:00:43,780 --> 00:00:48,120 things like that to Mars in advance of crew getting there, because the power level that 11 00:00:48,120 --> 00:00:52,250 we’re developing results in trip times that are too long for a crew. 12 00:00:52,250 --> 00:00:57,140 That same technology that we’re developing now is also been used for deep space robotic 13 00:00:57,140 --> 00:00:58,140 missions. 14 00:00:58,140 --> 00:01:03,809 There is a NASA mission called DAWN which has gone to the main belt asteroids and is 15 00:01:03,809 --> 00:01:05,820 currently orbiting Vesta. 16 00:01:05,820 --> 00:01:10,250 What’s exciting about electric propulsion is that we’re generating systems at high 17 00:01:10,250 --> 00:01:15,160 enough power that one day we could actually send crew and missions to Mars. 18 00:01:15,160 --> 00:01:19,620 To date the power levels that we’ve been operating on have worked very well for small 19 00:01:19,620 --> 00:01:24,960 deep space probes or for space craft in orbit around Earth but if we want to send large 20 00:01:24,960 --> 00:01:28,690 payloads and human crewed missions beyond Earth space, we’re going need this high
