Making weather forecasts is hard, complicated, scientific work. 70 per cent of its success depends on the accurate analysis of air pressure. Areas of pressure up to 9 kilometers above the Earth are measured by computers. Devices also record the vertical movement of air that can cause clouds, rain and snow. If the air goes down towards the Earth, it destroys the clouds and we can enjoy the blue sky. A front in the atmosphere is another important factor for predicting the weather. The fronts may stretch for thousands of kilometers and can be clearly seen from space. It’s interesting that cold fronts move faster than warm ones.

Scientists have long been working on new orbital technologies for growing plants. They tried to grow different plants on the International Space Station. Then the plants were sent back to the Earth for further study. This year, for the first time, astronauts could eat green leaves grown in space. Space farming is extremely important for the future space missions planned to Mars because it gives fresh food and vitamins. The new plant growing system is very smart. It informs humans when the plants need water. Special sensors measure the thickness of the leaves. If they become too thin, detectors send signals. This technology helps save water in space and grow a good harvest.

Within the next hundred years or so, people will have to get energy from alternative sources. Alternative sources are also needed to put a stop to pollution. There are different alternative sources that are already successfully used in many countries. One example is the Dead Sea, which produces electricity. When the sun heats the surface of the lake, the hotter and heavier layers of salty water sink. At the same time, the colder and lighter layers rise. The hot water can be stored at the bottom of the lake or piped away. It can be used to heat many buildings or to generate electricity. It costs only a third as much as oil heating.
