Challenges to Space Exploration a) We can round numbers to say light (and all electromagnetic radiation: radio waves, infrared, ultraviolet, etc.) travels at approximately 3x108 m/s. At its closest approach, Mars is about 0.5 au of the Earth. At this distance, how long would it take for an astronaut on Mars to communicate with Mission Control on Earth? Give your answer in minutes. Explain why Mars rovers have entire sequences for travel pre-programmed and uploaded all at once rather than being driven around in real time with a joystick. For the Earth-Moon distance in 5b, you can use 384,400 km b) The boosters that launched Apollo 11 allowed the astronauts to reach a speed of 25,000 miles per hour. At that speed, about how long did it take for the astronauts to reach the Moon? At that speed, how long would it take to reach Mars, assuming the closest approach distance given above? Give your answers in days.

TRUE OR FALSE: Write TRUE if the statement is correct and FALSE if otherwise. 1. Lorentz factor effect is only noticeable when the object is moving at great speed. 2. The dilated time will always have a value greater than the proper time. 3. Presbyopia is a disoder where the person have distorted or blurred vision at any distance Time dilation is only observable to a reference frame moving near the speed of light. Time dilation happens in any speed. 4. 5.
