En de NASA ook.

De hele ruimte wordt straks vol. Ik vind het ook heel raar dat dit allemaal mag. Ik bedoel, er is geen regelgeving hiervoor. En het is ook van zotte dat straks meerdere bedrijven allemaal satellieten mogen lanceren. 1 bedrijf zou genoeg moeten zijn om ruimte te sparen. Maar ja, ze willen allemaal geld verdienen. Straks kun je de sterren minder goed zien door al die duizenden satellieten.

Ja. Nouja, het is niet zo heel depressief allemaal hoor, want je kan zo alleen zien vlak na zonsondergang en voor zonsopgang (als het licht van de zon op die dingen schijnt). In het midden van de nacht zal je ze niet zien omdat ze dan in de schaduw van de aarde zitten.

Dan zijn het voornamelijk vliegtuigen die het zicht verpesten

His estimates suggest that once the first 1,584 satellites are launched, for which the trajectories have already been made public, there will be about 15 satellites clearly visible above the horizon for three to four hours after sunset and before sunrise.

This means that in winter there would be several hours of the night during which no satellites would be visible. But in summer the satellites would be visible all night.

Once all the 12,000 satellites are launched (assuming they are placed in similar orbits) 70 to 100 would be visible at night during the summer months, Bassa calculates. “These mega constellations are going to add drastically to the number of satellites that are visible at any time,” he said.

Néstor Espinoza, an astrophysicist at the Max Planck Institute for Astronomy, in Heidelberg, said: “It’s basically a private company staining our sky for everyone. It’s interesting that there’s no consensus about it. No one asked us.”

SpaceX is just one of nine companies known to be working on global space internet, meaning the eventual number of satellites could be far in excess of this.

The satellites, in addition to changing the face of the night sky, could be problematic for professional astronomers, said Espinoza. “We deal with satellites all the time. Whenever they come into your image you have to find ways to fix that. If you put 12,000 in the sky that will be a problem.”

This will be *even further* than Arabsat's center core landing (which was only 967km).The purpose of this change is not known.Keep cool, B1057. https://t.co/twS1wDKuxT reageer retweet
