SPACE TECHNOLOGY

TELESCOPES

• Telescopes are tools used to see things that are too far away
• This device gathers electromagnetic radiation
• There are two types of telescopes, reflecting and refracting
• A major telescope that has been launched into space is the Hubble telescope

SPECTROSCOPE

• Spectroscopes analyze the amounts and types of spectral light
• The spectral light comes from stars and planets
• They break down the light emitted or absorbed by stars or planets
• When the light is absorbed it turns the light into lines of color
• An example of a spectroscope is continuous spectra

SATELLITES

• A satellite is an artificial body placed in orbit around the earth or moon or another planet in order to collect information or for communication
• Satellites Are used for television, telephones, navigation, business and finance, weather, climate, and environmental monitoring, safety, land stewardship, envelop ant and space science.
• There are four different types of satellites- they are low earth orbits, sun synchronous orbits, geosynchronous satellites, and geostationary satellites.
• Satellites are used for many things and are used to discover many things beyond the earth that we can not see
• Satellites get into space on the tip of a rocket, the name of the rocket is called the launch vehicle

SPACE PROBES

• A space probe is a craft that travel to space to photograph, study, and land on celestial bodies
• They take pictures of planets, measure properties of space, & find unknown info on planets
• Landers, orbiters, and rovers are sophisticated probes
• Two future probes Earth will be sending are New Horizons and Venus Express
• Some probes carry telescopes that can peer far into the universe by detecting visible light

SPACE PROBES CON'T

• As a probe travels through the atmosphere, it's instruments identify gases
• and measure properties such as pressure and temperature.
• The largest volcano in the solar system was found on Mars thanks to the
• space probe, Mariner 9
• Examples: Sputnik, Mariner 10, & Magellan
