4 Useful websites: A useful website for the students to find information about the different planets. It explains the etymology of the planet s name, the moons each have, its size, temperature, orbit, etc. However, it is not updated as Pluto still appears in the webpage as a planet. gsaw/jigsaw.shtml A website for students to play a jigsaw puzzle of building a Solar System, ranging from planets, moons to space probes. vigation/visualization.cfm A useful website to visualise the Earth s structure and motion. ntent/visualizations/es0102/es0102page01.cfm?chapter _no=visualization

He enjoys diving, swimming and cycling. He graduated with a degree in Aeronautical Engineering from the Escuela Técnica Superior de Ingenieros Aeronáuticos, Universidad Politécnica, Madrid in He is a member of the Spanish Academy of Engineering. President Boris Yeltsin of the Russian Federation awarded him the Russian "Order of Friendship" in March He was awarded the "Great Cross of Aeronautical Merit" by the King of Spain in February He was also awarded the "Principe de Asturias" prize for International Cooperation alongside three other astronauts. Until 1992, he worked on the development of models for orbit computation software. He was also part of the Flight Control Team for ESA's ERS-1 satellite and EURECA, the European Retrievable Carrier. Duque was selected to join the ESA Astronaut Corps based at the European Astronaut Centre (EAC) in Cologne, Germany, in May He completed the Introductory and Basic Training Programs at EAC and a four-week training program at the Russian Cosmonaut Training Center in Star City, Russia.

76 Duque flew as Mission Specialist on the Space Shuttle Discovery, STS-95 mission on 29 October to 7 November This nine-day mission was dedicated to research in weightlessness and the study of the Sun. Duque was responsible, among others, for the five ESA scientific facilities on board and for the extensive computer system and configurations used on the Shuttle. From 18 to 28 October 2003, Pedro Duque participated in the Cervantes Mission. During this 10-day mission to the International Space Station (ISS), Duque served as Flight Engineer on the Soyuz-TMA, launching with the Expedition Eight crew and landing with Expedition Seven. Duque carried out an extensive experiment programme in the fields of life and physical sciences, earth observation, education and technology, including experiments in the Microgravity Science Glovebox, a research facility developed in Europe.

79 READING COMPREHENSION II Halley s Comet Halley s comet remains to be the most famous comet in history. It has been observed by astronomers since 240 BC. However, it was named after the astronomer, Edmund Halley, who observed a bright comet and noted that it was moving in an orbit similar to comets seen in 1531 and Edmund showed that the comet of 1682 was the same as the one seen in 1607, and he successfully predicted its return in Its most recent appearance was in February 9, It orbits the sun every years. The passing in 1986 was not the most spectacular. It could be seen by the naked eye in good locations with difficulty. Many spacecrafts were sent up to study the comet. One craft was the Giotta, a 950 kg probe that came within 500 km of the comets nucleus on March 13, The U.S.S.R then launched two probes, Vega 1 and Vega 2 in December 1994, which swung around Venus before coming within 10,000 km of the comet on 6 th and 9 th March. After that, Japan launched 138 kg Sakigake. It flew by at a distance of 7,000,000 km on March 11, It will appear next in mid-2061 and then in 2134.
