Radio signals travel at the speed of light and all other forms of electromagnetic radiation.
That means roughly 2.5 seconds to the moon and back, 8.7 minutes to Mars and back when it's
closest to earth, 17 minutes to the sun and back, 9 years to the nearest star and back, etc.

Why are rockets important?
Rockets are needed to lift payloads into space, whether it's to launch a satellite into an orbit around earth or to send a probe out into our solar system and beyond. A lot of speed is required to be able to escape the gravity of the earth. This is provided by the rocket and the huge amount of fuel.
What was Ptolemy's idea on space?
that the earth was in the middle of the universe
Who was the first dog to orbit the Earth?
The first dog to orbit the Earth was Laika, a Soviet space dog who was launched into space on November 3, 1957, aboard the spacecraft Sputnik 2.
How can you prove a round earth?
You can look at a picture of it taken from space, or the moon
What did the USSR accomplish before the US?
Sputnik, the first rocket into space many things to do with space: they got the first person into space the first satellite to launch into space the first orbit around the earth the first living being into space the first woman into space etc.
Where are radio waves faster-earth or space?
Radio waves travel with the highest speed in vacuum, and slightly slower in air. So they move slightly faster in space than on earth.
How did astronauts communicate with earth while in space?
Astronauts communicate with Earth using radio waves. They utilize communication devices onboard their spacecraft, such as antennas and radios, to transmit signals to ground stations on Earth, which then relay the information to mission control centers. This allows for real-time communication between astronauts in space and their team on the ground.
Which electromagnetic waves are used for communication in space?
Radio waves are predominantly used for communication in space due to their long wavelengths that enable them to travel long distances without much interference. These waves are able to penetrate Earth's atmosphere and travel through space to reach distant spacecraft and satellites.
This layer is responsible for the possibility of radio communication?
The ionosphere is the layer responsible for enabling long-distance radio communication by reflecting radio waves back to Earth. Its charged particles interact with radio waves, bending and reflecting them to facilitate communication over long distances. Without the ionosphere, radio waves would continue into space, limiting long-distance communication possibilities.
What did neil Armstrong use to communicate with people on earth when he was in space?
Neil Armstrong used a radio communication system to communicate with people on Earth during his missions in space. Specifically, he used a handheld radio and a headset, which were part of the Apollo spacecraft's communication equipment. This allowed him to relay important information and updates to Mission Control and share his experiences with audiences back on Earth. The system operated on HF (high frequency) radio waves to maintain contact over the vast distances of space.
What do space probes use to send information back to earth?
Space probes use radio waves to send information back to Earth. They are equipped with radio antennas that transmit the data collected by the instruments on board to communication satellites or directly to ground stations. The transmitted signals are received and processed by ground stations to analyze the data collected by the space probe.
How do space probes send images to earth?
Space probes typically transmit images back to Earth using radio waves. The images are converted into digital data and sent as radio signals to communication antennas on Earth. These antennas then receive the signals and decode them to reconstruct the images for scientists to study.
What is terrestrial and extra terrestrial noise in radio communication?
Terrestrial noise is noise that originates on the earth. Extra terrestrial noise comes from space.
How can the command centre communicate with the space ship in space if outer space is a vacuum?
They use radio waves which are a type of electromagnetic waves. Electromagnetic waves can travel through a vacuum Ligth is a type of electromagnetic wave and that travels through space from the sun and the stars.
What is the speed of a satellite signal?
The speed of a satellite signal is approximately the speed of light, which is about 299,792 kilometers per second. This means that signals transmitted from a satellite to Earth or vice versa travel at this high speed.

radio waves
How do you communicate earth to space?
