1. Satellites, Telescopes, Probes and Rovers

2. Definitions
Satellite – object that revolves around another object in space
Natural – the moon
Man-Made
Telescope – device built to observe distant objects by making them appear closer
Probes – unmanned spacecraft that collects information in space
Rovers – small robotic space probe that can move about the surface of a planet or moon

3. Artificial Satellites
International Space Station
multi-national effort (US, Russia, Europe, Japan, and Canada
orbiting Earth
Launched in 2000

4. Chandra X-Ray Observatory
Specially designed telescope that detects X-ray emission from very hot regions of the universe such as exploded stars and matter around black holes.
Helps them to understand what the universe is made of and how it was created
Because X-rays are absorbed by Earth’s atmosphere, Chandra must orbit above it

5. Hubble Telescope
Hubble was the first major optical telescope to be placed in space. Above the distortion of the atmosphere, far far above rain clouds and light pollution, Hubble has an unobstructed view of the universe. Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets in our solar system.
Hubble was launched in 1990

6. Spitzer Space Telescope
Formerly known as the Space Infrared Telescope Facility
is an infrared telescope that studies the early universe, young galaxies and forming stars

7. Compton Gamma Ray Observatory
On April 5, 1991, the Compton Gamma-ray Observatory (CGRO) was launched.
Detects the broad range of high energy radiation known as gamma-rays.
The observatory was safely deorbited and re-entered the Earth’s atmosphere on June 4, 2000.

8. NASA’s Great Observatories
Used to collect and analyze radiation emitted throughout the entire electromagnetic spectrum.
Series of four space-borne observatories designed to conduct astronomical studies over many different wavelengths (visible, gamma rays, X-rays, and infrared).

9. Fermi-Gamma-Ray Space Telescope
Launched in 2008
Uses gamma-ray detection equipment to study blazars and active galaxies, Gamma-ray bursts, Neutron stars, Cosmic rays and supernova remnants, The Milky Way galaxy, Gamma-ray background radiation, The early universe, Our solar system, Dark matter, and the unknown
Has shown us a structure centered in the Milky Way that may be the remnant of an eruption from a supersized black hole at the center of our galaxy

10. James Webb Space Telescope
The James Webb Space Telescope (sometimes called JWST or Webb) will be a large infrared telescope with a 6.5-meter primary mirror.  The telescope will be launched on an Ariane 5 rocket from French Guiana in October of 2018.
