Najgłębszy odwiert Ziemi

Najgłębszy odwiert Ziemi – For the deepest drilling on land experts believe a hole made on the Russian Kola Peninsula. Researchers began work in 1970., And already in 1984. Went down into the depths to 12 068 m. It was planned to pass through hard rock to a depth 13,5-15 km, but not proven diamond drilling tools and therefore are listed on a specially ceramic blades designed. Scientists surprised by, among others, numerous thermal springs flowing from the broken crystalline rocks on which it was assumed that they will be dry. When removing rock samples tore up under pressure, crumbling rock material, and sometimes exploded. The water temperature at the hole bottom was 220 ° C, pressure – 1,400 atmospheres.

Curiosity – Marsjański łazik Curiosity

CuriosityCuriosity

Curiosity – 6 August 2012. Mars rover Curiosity landed. The main objective of this most complicated equipment is to check that on Mars there were or there are conditions for microbial life. Equipment for the rover prepared scientific organizations from the USA, Canada, Germany, France, Russia and Spain.

Drive of the rover is radioisotopic thermoelectric generator that uses the natural decay of plutonium 238, which has proven itself in the American Viking missions of the program. Device is equipped with various revolutionary instruments for the analysis of soil, rocks and atmosphere. One of the devices is eg. Laser cannon that hits a rock from a distance of 7 m., And from the done spark is able to determine its chemical composition.

For more than eight months interplanetary probe covered more than 566 million km. Through the atmosphere of Mars flew at a speed of approx. 20800 km / h, but just above the reduced speed of just 3.22 km / h. Landing NASA has provided operators with seven minutes of terror, but in the end everything was a success. One of the biggest surprises of the mission was the discovery of a liquid, although salt water on Mars.
