  1. Moon Messages By the Solids Joseph, Will K , Polly and Holly

  2. Introduction A moon message is when two people on the moon communicate or when astronauts communicate with people on earth. They communicate with either a radio in their helmet or with sign language.

  3. SoundsinSpace • Sound cannot travel through the vacuum of space, but visible light and other forms of electromagnetic radiation can. One of these forms is commonly called radio. 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. Radio waves are often thought of as a form of sound because of their use in this way, but radio waves are not sound waves, they are a form of electromagnetic radiation analogous to visible light, and therefore can propagate through a vacuum.

  4. Satellites The first artificial satellite, Sputnik was launched by the USSR on October 4, 1957. Over 5, 000 satellites have since been launched into earth’s orbit and several hundred are still working in space. A number of satellites carry instruments for astronomical observation.

  5. Danger On The Moon Potentially dangerous small space rocks are smashing into the Moon a lot more often than was expected, according to an ongoing NASA study. "We've now seen 11 and possibly 12 lunar impacts since we started monitoring the Moon one year ago," said Bill Cooke, head of NASA's Meteoroid Environment Office. "That's about four times more hits than our computer models predicted."

  6. Astronauts • An astronaut or cosmonaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. While generally reserved for professional space travellers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists.

  7. Until 2002, astronauts were sponsored and trained exclusively by governments, either by the military, or by civilian space agencies. With the sub-orbital flight of the privately-funded Spaceship One in 2004, a new category of astronaut was created: the commercial astronaut.
