Why did it take 7 minutes for the radio signal to travel from the Curiosity back to earth?

Radio waves travel "at the speed of light" which, though very fast, is still a finite speed. Mars is far away so it takes 7 minutes for the radio waves to travel the distance from Curiosity to the Mars orbiter that then relays radio communications to Earth.
How much delay in the electronics of the relay station in the orbiter and the electronics on Earth I cannot be certain, but certainly a measurable amount though probably less than a few seconds.

What formula is used to figure the time it takes a radio signal to travel from Mars to Earth?
Radio waves, like all other waveforms in the electromagnetic spectrum travel at what is known as the speed of light. i.e. 3x10 to the power 8 metres per second (300,000,000) but the distance between the earth and mars varies enormously depending on their relative positions in their orbits around the sun. Anything from approx 35 million miles at it's nearest to about 340 million miles or thereabouts at it's furthest. So roughly 3 minutes minimum to about 30 minutes maximum.
The distance to mars is 7.5 x 1010 meters how long does it take for a radio signal from mars pathfinder to be received by nasa on earth?
light travels at approximately 300,000,000 m/s, so to pass 7.5*1010 meters it would take: 7.5*1010/300,000,000=250 seconds = 4.167 minutes P.S. Mars is not that close, in real life the signal takes about ten minutes to travel either way.
Robotic spacecraft on Mars have sent radio signals back to earth the distance from Mars to Earth at its greatest isi 401300000 km About how many minutes would it take a signal to reach Earth?
it takes 15768 mins it takes 15768 mins It takes 1337 Minutes
How long would it take radio signals to travel from Earth to Venus and back if Venus were at its farthest distance from Earth?
Practical Answer If the distance between Earth and Venus is to be maximum, then the two planets would have to be on opposite sides of the Sun. There would be no way to send radio waves to Venus in this situation as the waves cannot travel through the Sun. So, in reality, this question has no answer.Theoretical Answer For the sake of curiosity, lets assume the waves travel through the Sun in a straight line.: Earth's average distance from the sun = 93,000,000 miles Venus' average distance from the sun = 67,200,000 miles Max separation (opposite directions from the sun) = 160,200,000 miles Speed of radio (light) = 186,282 mi/sec Time for a radio or radar return = 2 x (160,200,000 / 186,282) = 1,720 seconds = 28-2/3 minutes(rounded)
How long does it take a radio signal from the Voyager spacecraft to reach Earth if the distance between Voyager and Earth is 4.16 109 km?
The speed of light is about 300,000 km/sec. Just divide the distance by the speed of light. The answer will be in seconds; divide by 60 to get minutes, by 3600 to get hours, or by 86400 to get days.

What is the time it takes for a signal to travel?
Communication with spacecraft is by means of radio. Signals travel at the speed of light. At that speed, signal travel one-way to or from the moon takes about 1 and 1/4 seconds. For Mars, depending on where the earth and Mars are in their orbits, radio communication one-way can take up to 22 minutes.
How fast did curiosity travel to mars?
It took the Curiosity Lander 253 days to get to Mars and the distance between Earth and Mars at their closest point is about 33,926,867 miles. Do the math correctly and the speed at which Curiosity was traveling was about 5,587 mph.
About how many minutes would it take a signal to reach Earth from Mars?
It varies, depending on the positions of Earth and Mars. It can be anywhere between 3 and 22 minutes. When this answer was written (6/27/2009), Mars was approximately 177 million miles from Earth which works out to about 15.84 light-minutes.
How long does it take the light to travel to the earth?
It takes Light 8 Minutes to get from the Sun to the Earth.
How long does it take a message to travel from Earth to a spacecraft on Mars at its farthest from Earth?
22.2 minutes
