SpaceX launches 60-satellites to bring internet everywhere
The OTHER 60 satellites Starlink of SpaceX are going to take off from the base of Cape Canaveral in Florida. This is the fourth launch for the global Internet, the third of the operational satellites, which will be deposited in orbit powered by a Falcon 9. The liftoff is scheduled for 15.49 time. The carrier is a rocket already used a couple of times, we read in the press release issued from the same SpaceX: the first in the demonstration test that resulted in the capsule Crew Dragon (which one day will carry astronauts in space) to dock with the international space Station (Iss) in march 2019. The second, in June of last year, for the launch of the constellation Radarsat. The launch in live streaming The release of the satellites is expected, according to the roadmap provided by the partner, after a little more than an hour, at an altitude of 230 km. Their orbit is to be raised later, after checking on their status and on the operation. In the meantime, the first stage of the Falcon 9 will attempt the now usual landing on the platform off the Atlantic ocean “Of course I still love you”, which will take place in about eight and a half minutes from take-off. The mega constellation We are at 240, therefore, there will be many, from this afternoon, the mini-satellites of the company founded by the mogul's south african, born american, to darting across the sky. The promise is to bring broadband Internet anywhere in the world, even in the most remote locations and in less developed countries. In the plans of Elon Musk , the mega constellation will have to count the 12,000 satellites to be fully operational. Many of them have been approved by the Itu (International telecommunication union), the international body for the allocation of radio frequencies for telecommunications and the Federal communications commission statuniense. But SpaceX has made application for the approval of 30,000 other satellites. The reason for this is the duration (a few years) of each satellite in orbit, and a replacement is necessary and continuous.

this Is, however, a total of 42,000 satellites: more than eight times the number of objects (active and inactive) currently present in orbit (excluding debris). Traffic ever seen by the beginning of the space age, and that did turn up their nose, if not worse, to a multitude of scientists and not only. In several, indeed, have noticed (even to the naked eye) the brilliant “trains” of lights is just around the corner and disturb the vision of the night sky. Damage that might compromise the observation of the sky by part of the scientific instruments very sophisticated and sensitive, both in the light spectrum in the radio waves to the radioastronomi.

In this regard, Musk and SpaceX have said that they will be taken measures to ensure that the band in which the satellites transmit to the Earth is not disruptive to the investigations of the telescopes radio, and that the satellites themselves will be painted with a special paint to make them less reflective.
The other big potential problem is that of a possible collision with other satellites and space debris. Here, SpaceX ensures that each satellite is equipped with a system of “collision avoidance”, to avoid impacts with other objects. This has not prevented that scattasse the alarm on September 2, 2019, for a collision of the probe of the european space Agency Aeolus and one of the satellites in the constellation, Starlink. At that time, were the flight engineers of the Esa to move the Aeolus on an orbit different to avoid the impact. After you have tried to contact SpaceX to coordinate and you have not received a response. They had not read the mail.
