- Approximately how long would it take a telephone signal to travel 5.46 x 10^10 m from Earth to Mars ?Approximately how long would it take a radio signal to reach the International Space Station (ISS) at an orbital altitude of 350 km? =_______________ The answer is not 0.0012 according to my software that is incorrectIf we send astronauts to Mars, there will be a time delay anytime we send or receive messages to them here on Earth. Given that Mars is an average of 54.6 million km away from Earth, how long is this time delay for a 2-way 'round-trip' communication - sent to Earth, then back to Mars? (this might be important in emergency situations) answer choices a)About 4 minutes. b)About 30 seconds. c)About 10 seconds. d)About 6 minutes.
- 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. Find the shortest delay time for the signal that you send to Mars from Earth in seconds.The Curiosity Rover has recently landed on Mars and likes to send Twitter updates on its progress. If a tweet is posted 13 minutes after it was sent, how far is Curiosity from Earth? (Assume there is no network lag.)Earth is on average a distance of 2.25 x 1011 m away from Mars. If a radio signal is sent from Earth traveling at a speed of 3.0 x 108 m/s, how many seconds would it take to be received on Mars?
- The spacecraft that have landed on Mars send their information to the Earth via radio waves. How long do these waves take to reach the Earth when (a) Mars is at its closest to the Earth? (b) Mars is farthest from the Earth? This time delay is important for NASA when it sends a spacecraft to Mars.If Mars is 1.5x108 km from Earth, how long does it take radio signals from the Curiosity rover to reach us? (the speed of light is about 3x105 km/sec)A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 7.88×10^7km. Radio waves travel at the speed of light (3.00×10^8m/s). How many seconds does it take for the signal to reach the Earth?
- Approximately how long would it take a telephone signal to Travel 480 km ( 1km= 1000m) from earth to the international space station? ( telephone signals travel at the speed of light).NASA sends a radio signal to a robot on Mars, which is 225 x106 km from Earth. How long does it take the rover to get the radio signal? A radio wave travels at 3x108 m/s. .75 sec 1.33 sec Instantly 12.5 minUnder ideal conditions and when Mars is closest, estimate the linear separation between two objects on Mars that can barely be resolved by (a) the naked eye and (b) the Hubble telescope (whose main mirror is 2.4 meters in diameter). (Hint: the answers are about 5000 km and 14 km)
