10 most impressive space accidents
Since the launch of the first satellite into the orbit in 1957, a person thoroughly closed the near-earth space. Around the planet turns more than 20,000 man-made objects of minimum size with a baseball ball. At a speed of over 28,000 km / h there is nothing strange that collisions occur quite often. Although this is not the only reason for space accidents.
1. Suicide Galileo
Galileo’s interplanetary station began his journey in 1989 and spent 14 years in space, 8 of whom dedicated to the study of Jupiter and his satellites. When the mission of the device ended, he was sent to the atmosphere of the giant gas planet, where Galileo and melted. Such a solution was dictated by the concern that the station would face one of the potentially inhabited satellites of Jupiter and will bring earth microorganisms there.
2. Destruction USA-193
In 2006, the USA-193 Super Secretary Navy lost contact with the Earth immediately after the successful conclusion into orbit. In the tanks of the device weighing 2300 kg, 454 kg of toxic hydrazine fuel remained. So that the poison does not hit the surface of the earth, it was impossible to let the process of lowering the satellite on satellite. In 2008, USA-193 released the SM-3 missile, which struck the target at a height of 247 km above the Pacific Ocean.
3. Cerise fell by her own rocket
The 50-kilogram satellite of Cerise (from the French "Cherry") was designed by order of the French secret service to intercept high-frequency radio signals. In July 2005, the ARIANE-4 carrier rocket brought the "spy" into the near-sole space. But a year later, something displaced the device with orbits, damaging the gravitational stabilization device. This "something" was a fragment of the Ariane-1 rocket stage.
4. Unsuccessful joking
Satellite Robot Dart (Demonstration for Autonomous RendezVous Technology, "Demonstration of Autonomous Docking Technologies") was created by NASA for servicing spacecraft, such as Hubble Telescope. However, during DART test flight crashed into the goal of docking – Mublcom Military Satellite. Now both satellites are rotating in low orbits and will gradually lose height until they burn in the atmosphere.
5. Pegaso delays in the "cyclone"
In 1985, the "Cyclone-3" launch vehicle brought into orbit the Soviet satellite of radiotechnical intelligence "Cosmos-1666". Unfortunately, the last stage of the rocket remains in the near-earth space. After 28 years, the stage fell into the cloud of cosmic fragments, which made it even more dangerous. In 2013, the flying pile of the rubble injured the antenna of the first and sole satellite of Ecuador Pegaso. As a result, the device has changed the orbit and stopped responding to signals from the ground.
