25.3 Applications of electromagnetic waves * Communicating with Mars Imagine that you have a vehicle traveling on Mars. The shortest distance between Earth and Mars is 56 × 10 6 km; the longest is 400 × 10 6 km. What is the delay time for the signal that you send to Mars from Earth? Can you use radio signals to give commands to the vehicle?
