The mission to Mars is a mission to have humans living in outer space on day. After many failed attempts of sending space probes and rovers to Mars, in 1964, there was success. 21 images were sent back to Earth from Mars with evidence of places where humans could live. Using Mars Exploration Rovers, the mission has become more possible over the years with discovery of an ice cap and life forms. There is a hope that we can one day as humans live on this mysterious red planet.

The Hubble Telescope was launched into space on April 24th, 1990 which gave humanity one of its greatest advances for space exploration. It is one of NASA's most successful and long-lasting science missions. It works by orbiting the earth just above the atmosphere, which distorts and blocks the light that reaches our planet, gives it a view of the universe that typically far surpasses that of ground-based telescopes. The Hubble Space Telescope collects light and other electromagnetic radiation, which is then directed by mirrors to special science instruments. It was named after astronomer Edwin Powell Hubble, who made some of the most important discoveries in modern astronomy.

Space Probes

Space probes are basically machines launched into space by scientists. The first successful one was the Luna I launched by the Soviet Union in 1959. Other examples of space probes are Voyager I and Voyager 2. Space probes are operated from Earth and do not need to be piloted by astronauts. They provide information about things outside of our planet such as the Voyager missions providing data about planets, galaxies and other things outside our galaxy.
