How do spacecraft know where they are?
Generally, NASA uses the downlink, or radio signal from a spacecraft to a radio telescope in the DSN, to tell where it is. The distance between Earth and the ship is measured by sending up a radio signal from Earth with a time code on it. They can compare how far the ship is from each signal.
How do spaceships communicate with each other?
Messages travel through space as radio waves, just like the radio waves that you receive with a car radio. Each spacecraft has a transmitter and a receiver for radio waves as well as a way of interpreting the information received and acting on it. NASA has huge radio receivers to gather information from space missions.
How do spaceships know where to land?
Answer by C Stuart Hardwick, award-winning science fiction author, on Quora: Spacecraft landing points are selected and orchestrated using what the US military calls (sensibly enough) backwards planning. You start with the desired endpoint, then back out all the operations and timings needed to get you there.
What is location in space?
Well, Earth is located in the universe in the Virgo Supercluster of galaxies. A supercluster is a group of galaxies held together by gravity. Within this supercluster we are in a smaller group of galaxies called the Local Group.
How do astronauts communicate from space to Earth?
How do astronauts communicate with each other? The astronauts have devices in their helmets which transfer the sound waves from their voices into radio waves and transmit it to the ground (or other astronauts in space). This is exactly the same as how your radio at home works.
How do you communicate with the International Space Station?
If someone does need to “call” the ISS, operators at mission control centres simply relay the audio through a telephone line to Houston into the very high frequency space-to-ground radio network. The phone number at NASA Johnson Space Center is +1 281-483-0123, but your chances of getting through to the ISS are slim.
