These are the advantages of space wave propagation: – These waves have an ability to propagate from transmitter antenna to the receiver antenna through the space. – These waves are capable for travelling from earth surface to the troposphere surface of earth after reflecting from earth.
Q. Why do astronomers place telescopes in Earth orbit?
Astronomers place telescopes in Earth orbit in order to observe radiation from those parts of the EM spectrum for which the atmosphere would normally absorb or significantly scatter that radiation.

Q. What type of waves can we use to explore space?
Telescopes
- Optical telescopes observe visible light from space.
- Radio telescopes detect radio waves coming from space.
- Objects in the universe emit other electromagnetic radiation such as infrared , X-rays and gamma rays.
Q. How do we use space technology in everyday life?
Inventions we use every day that were actually created for space exploration
- Artificial limbs.
- Scratch-resistant lenses.
- Insulin pump.
- Firefighting equipment.
- DustBusters.
- LASIK.
- Shock absorbers for buildings.
- Solar cells.
Q. What kind of technology is used in space?
Space technology includes space vehicles such as spacecraft, satellites, space stations and orbital launch vehicles; deep-space communication; in-space propulsion; and a wide variety of other technologies including support infrastructure equipment, and procedures.
Q. How do astronauts talk 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.
Q. Who has the most advanced space technology?
US. The US is currently leading the chart of the top 10 countries in space technology, accounting for over 30% of the operational spacecraft currently in orbit around Earth.
Q. What radio frequency do satellites use?
C-band (4–8 GHz) Primarily used for satellite communications, for full-time satellite TV networks or raw satellite feeds.
Q. What frequency do astronauts use?
The ISS radio transmits signals at 145.80 MHz and receives signals at either 144.49 or 145.20 MHz, depending on its orbital location.
Q. How far can a 5w radio transmit?
The 5 watt radio can reach up to 12 miles or more. Some handheld radios have 6 watts which can reach up to 20 miles in the right conditions.
