An interstellar space probe is launched from earth. after a brief period of acceleration it moves with a constant velocity, 70.0% of the speed of light. its nuclear-powered batteries supply the energy to keep its data transmitter active continuously. the batteries have a lifetime of 15.9 years as measured in a rest frame. (a) how long do the batteries on the space probe last as measured by mission control on earth?
yr
(b) how far is the probe from earth when its batteries fail, as measured by mission control?
ly
(c) how far is the probe from earth, as measured by its built-in trip odometer; when its batteries fail?
ly
