Explain how a Refracting Telescope works and how it is useful?
Refracting Telescopes use a lens to bend light which allows astronomers to be able to see celestial objects from further away by focusing more light.
Explain how a Reflecting Telescope works and how it is useful?
Reflecting Telescopes use a mirror to reflect light onto another smaller mirror which allows astronomers to see celestial objects from further away.
What does the ISS stand for?
International Space Station
What are Rovers and what do they do?
Rovers are a type of robotic technology, equipped with multiple cameras and scientific instruments to analyze different things.
Explain the Canadarm2 and what is does?
Canadarm2 was designed by the Canadian Space Agency and is connected to the ISS. Canadarm2 has robotic arms to carry heavy objects and fix stuff on the ship.
What was so special about the Geocentric Model of the Solar System?
The Geocentric Model was one of the first historical models of the Solar System.
What was so special about the Heliocentric Model of the Solar System?
The Heliocentric Model put the Sun in the middle of the Solar System with all the other planets orbiting around it.
