History Of Mars Rovers
The first Mars Rovers were Marsnick 1 &2, both failed and were launched from the Soviet Union in 1960.

The first successful Mars "Rover" was Mariner 2 launched by NASA in the United States. It was a flyby mission and collected 21 photographs.
DSN
DSN is composed of three deep-space communications facilities. One in California's Majave Desert, one near Madrid Spain, and the last near Canberra Australia. The placement of each facility allows for the the rover to be correctly tracked and always in contact with Earth as it rotates
Antenna Stats
The antenna that work together to make DSN are huge. 34 by 70 meters, they allow us to reach and communicate clearly with spacecraft millions of miles away.
Intro to Mars Rovers
An automated motor vehicle that moves across the surface of the planet upon arrival, collects samples, photographs, and other data.
What is She Worth?
$2.47 billion
Why Explore Mars?
The possibility of life on Mars or the possibility of Mars once sustaining life has been the major force behind it's exploration

How do we control Curiosity from Earth?
NASA uses DSN (Deep Space Network) which is a international network of antenna and satellites that provide a link between scientists and engineers on the ground to Curiosity on Mars along with flybys, orbiters , and tones
EDL
Entry, descent, landing. The roughest parts of a Mars Rover's journey are the hardest to track. Friction which causes heat, airbags that cause jerking, parachutes that yank and make it difficult to tell what it going on. In preparation for that, NASA uses various tones (sounds) to assist in controlling the spacecraft. There are 256 distinct tones in all.
Everyday...
Learn, sample, test, shoot, explore.
The everyday use of any rover is to learn something new, learn more, learn on a deeper level. Discover.
Orbiters and Flybys
The Mars Odessey is a Mars orbiter used to track and control the Mars rover, Curiosity. It acts as a relay for UHF radio signals
The Mars Global Surveyor was also used to track and control Curiosity until it stopped communicating with Earth after 10 years of service
