The unmanned spacecraft Viking II landed on Mars and took the first pictures of the surface of Mars. The Viking spacecraft was launched inside the nose cone of a Titan Centaur rocket was made of two parts: an orbiter and a Lander The Lander housed instruments for examining physical and magnetic properties of the soil; analyzed the atmosphere and weather patterns of Mars; and determined any evidence of past or present life. The orbiter's initial job was to survey the planet for a suitable landing site. Later the orbiter's instruments studied the planet and its atmosphere, while the orbiter acted as a radio relay station for transmitting Lander data.
A US satellite has detected ozone "hole" over Antarctica, which is three times larger than the entire landmass of the United States. It is the largest such area ever observed, Image, compiled from NASA's Total Ozone Mapping Spectrometer instrument onboard the Earth Probe satellite, reveals how the ozone hole (in deep blue) has extended as far as southern Chile. With the result the Earth is warming, the oceans are warming. Vast areas of the planet will become uninhabitable to loved ones; we do need to find a solution.
