COMETS from Illustrated London News, 1985 There can be few people who have not heard of comets, but there are still a great many non-scientists who have no real idea of what a comet is. The most popular mistake is to assume that a comet streaks across the sky and disappears in a few seconds.
SPACE TRAVEL People have always wanted to know more about the other planets in our universe. Long ago, they found out that our earth is not flat but round, and that the moon goes round the sun. Telescopes were built to see planets far away in space better. But, of course, this was never enough.
– SPACE TOURISM – Japan’s Shimizu Corporation is making plans for the day that there are regular flights into space, not by astronauts, but by tourists and sightseers. Shimizu’s space project office prepared the plan for a $28 billion space hotel with the technical guidance of Bell & Trotti of the United States.
LIFE IN SPACE – 2 We haven’t conquered space. Not yet. We have sent some 20 men on camping trips to the moon, and the USA and the Soviet Union have sent people to spend restricted lives orbiting. Earth. Several trips have been made into space to show that ordinary (non- astronaut) scientists can live and work in space – for a few days only. All these are marvellous technical and human achievements, but none of them involves living independently in space.
– HALLEY’S COMET – A comet is an object that travels around the sun leaving a bright trail behind. For more than two thousand years, the return of Halley’s Comet has been observed and recorded on Earth every 76 years.Its 1986 visit, however, was the first time that humans took a close look at its nucleus.
– THE OZONE LAYER – The end of the human race cannot be put before the interests of aerosol manufacturers. This important decision was reached by the top brains of twenty-four countries in Montreal this September.
– LEARNING ABOUT MARS – (by Dr. Ken Grady, 1980) – ->People have always been quite excited about details on Mars because Earth and Mars have many characteristics in common. Just like Earth, Mars turns around itself. It takes Mars twenty-four hours, thirty-seven minutes and twenty-seven seconds to complete one turn, so the day on Mars is a bit longer than ours.
