At noon a rocket ship passes the Earth with a velocity 0.8c. Observers on the ship and on the Earth agree that it is noon.
a) At 12:30 pm as read by a rocket ship clock, the ship passes an interplanetary navigational station that is fixed relative to the Earth and where clocks read Earth time. What time is it at the station?
b) How far from Earth (in the Earth coordinates) is the station?
