ESA’s New Video Tips off Risks Pose by Cosmic Debris to Satellites & Astronauts

The European Space Agency (ESA) has recently released a new video, cautioning about the risks, pose by the cosmic debris to the satellites, spacecraft and onboard astronauts.

Space debris or junks and wastes are now considered to be one of the major threats to the orbiting satellites, spacecraft and the astronauts. As expected by scientists across the globe, the ever-increasing cloud, consisting more than 750 000 hazardous wreckage objects and measuring bigger than 1 cm are moving in Earth orbit, and this is posing higher potential damages to the intact satellites, and spaceships, orbiting the earth.

Now, confirming the intensification of this risks and hazards, the European Space Agency (ESA) has released a video, that shows the potential hazards, created by cosmic debris to satellites and astronauts. The video warned about the possible dangers that celestial fragments pose especially to human-made objects like satellite and spaceships in the space. The debris also can cause harm to the astronauts onboard the spacecraft, cautioned ESA in its new video.

To deal with these possible risks, a team of international scientists are going to meet up in an assembly in Germany next week, where they will discuss the matter of how ‘millions of cosmic debris and objects’ soaring in orbit around the world may cause a catastrophic collision in the space.

Since 1957, where the global space industry started to blossom, more than 4,900 spacecraft and satellites have been launched into space – leaving millions of remains behind in space. Out of those million fragments, nearly 94% objects are no longer used for any functional purpose, and they are randomly floating in the earth orbit. Now, ESA doubts that these randomly floating objects could one day initiate a disastrous harm to human-made space technology.

Commenting on the latest video, Holger Krag, chief of space debris at the European Space Agency said, “ space rubbishes are not even comparable to gunfire. The energy enclosed in a small one centimetre or 0.4-inch particle can hit a satellite at such a velocity, which almost corresponds to an ignition of a grenade. These collisions can again set off more particles and debris, and these particles are major aspirants for new clashes to come.”
