How long is the communication delay to the ISS?
When the planets are at their greatest distance — about 250 million miles away — the delay is around 24 minutes. This means that astronauts would need to wait between four and 24 minutes for their messages to reach mission control, and another four to 24 minutes to receive a response.
How long does a message take to get to the ISS?
Alerts are generally sent about 12 hours before the International Space Station pass. This means you’ll receive the message the night before for a morning pass and the morning of for an evening pass.
Why is there a time delay between the time we send a radio message to astronauts on the moon and when they receive it?
Answer 2: This happens all the time! Because all the communication signals travel at the speed of light, they travel very quickly. However, there are very large distances in space, and the delay becomes more noticeable when missions are further away from the Earth.
Why does it take so long to dock to the ISS?
Everything in our solar system revolves around the sun, so objects are never in a fixed location. That means spaceships can’t take a direct path to their destination; they need to go in a spiral so that they eventually cross paths with the orbit of the planet or space station they’re trying to reach.
How long does a radio signal take to get to Mars?
about 5 to 20 minutes
Ultra-High Frequency Antenna It generally takes about 5 to 20 minutes for a radio signal to travel the distance between Mars and Earth, depending on planet positions. Using orbiters to relay messages is beneficial because they are much closer to Perseverance than the Deep Space Network (DSN) antennas on Earth.
How far can radio signals travel in space?
The greatest distance for a transmission by a human-built device is currently about 13,482,762,800 miles, and growing by the minute. The greatest distance over which radio signals can be received is some hundreds of millions of lightyears; radio astronomers do that regularly.
How long does it take a radio signal to get to the moon?
2.7 seconds
Radio waves propagate in vacuum at the speed of light c, exactly 299,792,458 m/s. Propagation time to the Moon and back ranges from 2.4 to 2.7 seconds, with an average of 2.56 seconds (the average distance from Earth to the Moon is 384,400 km).
