    • 23. Eclipses A solar eclipse happens when the Moon passes between the Sun and the Earth. This casts a shadow over the Earth. The last solar eclipse over the UK was on 11th August 1999. Solar eclipses do not occur very often. A lunar eclipse happens when the Earth passes between the Sun and the Moon. This casts a shadow over the Moon. Lunar eclipses happen in most years. 1 of 20 23 of 58 © Boardworks Ltd 2004 2005

    • 45. Beyond the Solar System For thousands of years, humans have been fascinated by the night sky and what lays beyond it. 1 of 20 45 of 58 © Boardworks Ltd 2004 2005
    • 46. Satellites – science fiction to science fact Science fiction writers first suggested the idea that artificial satellites could be put into orbit around the Earth. This only became reality in 1957 when the Soviet Union placed Sputnik I and Sputnik II into orbit – Sputnik II carried a live dog called Laika! Today, artificial satellites are frequently launched by space shuttles and unmanned rockets. Artificial satellites have many uses including communications, satellite TV, weather forecasting and navigation. 1 of 20 46 of 58 © Boardworks Ltd 2004 2005
    • 47. Using satellites to view space Astronomical satellites, such as the Hubble Space Telescope (HST), are large telescopes placed in a high orbit far from the effects of the Earth’s atmosphere. These satellites can ‘see’ much further into space and give us images of stars and galaxies many light years away, like this cartwheel galaxy. 1 of 20 47 of 58 © Boardworks Ltd 2004 2005
    • 48. Exploring space – mission to Mars Our search for answers and clues to the origin of the Solar System and the possibility of life elsewhere led to the development of unmanned space probes. For years, science fiction had brought us stories of Martians - but could they really exist or have existed? On 4th December 1996, NASA launched the ‘Pathfinder’ Discovery Mission to Mars. It cost $150 million and took 7 months to reach Mars. When it had landed, the ‘Sojourner Rover’ buggy tested Mars’ atmosphere, surface and weather, amongst other things. 1 of 20 48 of 58 © Boardworks Ltd 2004 2005

    • 51. Mission to Mars – tests on Mars The tests carried out by the Rover showed that Mars is much more like the Earth than was expected. Was Mars like the Earth until something catastrophic happened? 1 of 20 51 of 58 © Boardworks Ltd 2004 2005
    • 52. Mission to Mars – volcanoes on Mars The tests also showed that the crust of Mars is very similar to continental crust on Earth and that volcanoes had played a part in Mars’ formation. Why did the volcanoes stop? Did the gases they gave out kill any Martian life? 1 of 20 52 of 58 © Boardworks Ltd 2004 2005
    • 53. Mission to Mars – erosion on Mars The surface of Mars has undergone intense erosion by massive floods and by strong winds. Did it rain on Mars? How much water was there on Mars? Was there life in the water? 1 of 20 53 of 58 © Boardworks Ltd 2004 2005
    • 54. Questions about satellites and probes 1. Give two uses of artificial satellites. 2. Why can the Hubble Space Telescope ‘see’ much further into space and produce much clearer images than telescopes on Earth? 3. Why didn’t NASA send astronauts to Mars instead of spending millions of dollars on the ‘Pathfinder’ Discovery Mission? 4. Give two reasons why there is unlikely to be life on Mars. 1 of 20 54 of 58 © Boardworks Ltd 2004 2005
