Puerto Rico closed the observatory that sent messages to space
One of the world’s largest radio telescope in the Arecibo Observatory, Puerto Rico will cease to use due to the threat of collapse, writes the "Science" channel.
It is reported that the cables ceased to withstand the load, attempts to repair are dangerous for people’s lives.
The telescope reflector is located in a natural quarple funnel, a 900-ton tool platform is suspended above it at an altitude of 123 m. In August, one of the auxiliary cables broke away. While in the observatory, the delivery of spare auxiliary cables was waiting, on November 6, the main cable was cut off. Having examined the damage, the engineers came to the conclusion that the loads were within the allowed range, which means that the remaining cables are also weaker than was supposed initially.
Before the design analysis, the territory is examined with drones. Arecibo worked 57 years. In 1974, a radio signal was sent from the Observatory in the constellation of Hercules, called the "Mecibibibo message". The message contained information on the numbers, the main earth chemical elements, nucleotides and the DNA helix, the human anatomy, the solar system and the telescope itself.
To achieve a goal, the message will take 25,000 years old, and then the same as much mankind has to wait for the answer.
