Telescopes, Satellites, & Space Agencies
Telescopes discovered Uranus, Neptune, & Pluto. With this telescope, Muggles are able to locate asteroids, comets, stars, galaxies, moons, & planets that cycle other nearby stars. Back then, telescopes used two lenses; one for your eye & the other to magnify. Telescopes had objective lens that were convex, & the eyepiece that were concave. If you take a number & multiply it, you will get the square number. For example, two times two equals four; four is the square number. If you make the objective lens larger, it will enhance the telescope's target. Muggle GPS is used by artificial satellites. The Hubble telescope is on a satellite that orbits the Earth. The United States, Europe, Japan, Russia, & Canada built the International Space Station together.
Space Shuttles, Radar, & Rovers
The Space Shuttle Transportation System was run by NASA in 1980. Russia launched the Soyuz space shuttle. Fourteen astronauts were killed on space shuttles. China was the first to land a space shuttle on the farthest side of the Moon. A few natural satellites that were researched is the Moon, Mercury, Saturn's rings, & Venus. Rovers can be self-driven, driven from Earth, & can carry & drive people. They let those of us on Earth to study planets & moons by pictures, readings on the atmosphere, & snippets of dust & rock.
Fun Facts
⊱ Ancient Greeks used 360 degrees in a circle. Half of a circle is 180 degrees. A degree is 60 arcminutes. In an arcminute, it has 60 arcseconds.
⊱ The Keck telescope is 10 m in diameter.
⊱ Satellites can be used to take pictures of Earth, analyze clouds & temperatures, as well as rainfall, & to put telescopes in space.
⊱ Radar is used for military purposes, air control, traffic flow, locate places, & surveying weather.
