Several countries, including Switzerland, closely followed the fall of the Russian cargo. The latter did not finally arrive around on earth, he will burn in the atmosphere.

The unmanned Progress cargo ship, plummeting into space from the loss of control there one week Russian operators must disintegrate Friday entering the atmosphere, said Wednesday the Russian space agency Roscosmos.

According to the calculations of specialists Roscosmos, it will disintegrate May 8th between 1:23 ET 9:55 p.m.. "The ship will burn in full through the layers of the atmosphere of the Earth, and only a few small fragments will reach the surface of the planet," the agency said in a statement.

A few hours after takeoff on April 28, the Progress M-27M, which was to dock Tuesday at the International Space Station that was to supply, has not responded to the Russian engineers started having uncontrollable reactions.

A commission of inquiry was mandated to establish the circumstances of the incident, which seems to have occurred at the time of separation between the ship and the rocket, it had estimated a week ago the vice president of Roscosmos, Alexander Ivanov.

"Breaking"

The loss of this ship which cost almost half a billion Euros is a blow to the Russian space sector, a strategic area, already in the sights of power for stinging setbacks.

But it does not endanger the crew of the ISS which has several months of reserves. A supply ship Dragon, the US company SpaceX, should join the ISS at the earliest on June 19

Three to four Progress cargo ships are sent each year in space, bringing equipment and other supplies necessary for life on the ISS. After their mission, they fall and burn up in the atmosphere above the Pacific Ocean.

That’s generally safe because the ocean is 160+ million square kilometers in area, and much of that real estate is empty of islands. But not in this case. You’re probably seeing the solar panels, antennae, and various other external bits being stripped off and leaving their own meteoric trails.

This same thing happens to meteors as well, but they’re moving much faster as they come in from interplanetary space, blasting in at a minimum of 11 km/sec (7 miles/sec). But the principle is the same.

The risk that Switzerland is affected by debris from the Progress M-27M is minimal, had said Monday the Federal Department of Defence, Protection of the Population and Sport (DDPS).
