1 In one of the NASA Space Shuttles, about 76,526 earth years (38,263 earth years one way). 2  1 light-year is 5.8 trillion miles and the maximum speed of a NASA Space Shuttle is 17,500 miles per hour. 3  The fastest unmanned space craft traveled 157,000 mph.
Actually I think the answer would be C. 8 earth years. The reason for this is because light years is literally the amount of time it takes for light to travel in a earth year. There is no mathematical expression needed for this, it says it in the problem. If it takes light to travel 8 years to a star its 8 earth years. The answer is C. Thank you though!
