to see what is listening on the other side i think.but it is pointless to do,sinds stars are light years away from us and to get an answer back Will also take years to get back at us.also i don't think that it Good for us tell where were at in the universe don't think aliens will come in peace when they visit us
Scientists have sent radio messages into space in hopes of contacting potential extraterrestrial civilizations. This effort, known as METI (Messaging Extraterrestrial Intelligence), aims to engage in interstellar communication and potentially establish contact with intelligent beings beyond Earth.
Scientists communicate with spacecraft in space using radio waves. Ground stations on Earth send commands to the spacecraft and receive data from it through radio signals. These signals travel through the vacuum of space to maintain communication with spacecraft regardless of their location in the solar system.
It is so that scientists, could investigate the effects of space exploration.
by radio
they also sent Monkeys. They did this to see what would happen if they sent them to the moon and Other places.
The first object sent into space to orbit Earth was Sputnik 1, launched by the Soviet Union on October 4, 1957. This historic satellite marked the beginning of the space age and the start of the space race between the United States and the Soviet Union. Weighing about 58 pounds, Sputnik 1 transmitted radio signals back to Earth, allowing scientists to study its orbit and the effects of space on radio waves.
Messages from Apollo 11 were sent using radio signals between the spacecraft and Earth-based tracking stations. The tracking stations picked up the signals and relayed them to mission control in Houston. These messages included voice communications, telemetry data, and video transmissions.
they were calm and easy to train
Hi thereOn October 4th 1957 the Soviet satellite "Sputnic", the worlds first artificial satellite, blasted into space and transmitted information via radio signals to Soviet scientists for three weeks.Hope this helped you.
before the radio was invented, people and countries sent messages/letters carried by messengers to the destination wherever it may be located.
Radio signals are sent from Earth, to operate the telescopes.
Yes
