SpaceX Starlink satellites continue to ruin it for astronomers – Technology News, Firstpost

The massive swarm of internet radiating satellites in the growing Starlink constellation launched by SpaceX continues to be a thorn in the side and a hindrance to the astronomy community.

The massive constellation of Starlink satellites launched by SpaceX continues to be a thorn in the side of astronomers around the world.

As of May 201

9, SpaceX has launched batches of its Starlink satellites – 60 each – with the ultimate goal of reaching a “mega-constellation” of around 30,000 small satellites with internet radiation.

Not long after the first batch of Starlink satellites launched in 2019The astronomers quickly realized that the volume and reflectivity of the satellites made them visible in the night sky – as an unmistakable trail of light in the sky.

The satellites were so reflective that they hindered the already complex work study the cosmos in space observatories around the world.

The US-operated Vera C Rubin Observatory in Chile is a gigantic telescope that has been in operation for over two decades and is priced in the millions. It was designed to begin the deepest mapping of the night sky ever in 2022 Report in the guardAstronomers are now wondering how the Starlink constellation grazes their images every night and what could hinder them in doing so.

    DarkSats not dark enough: SpaceX Starlink satellites continue to ruin it for astronomers

Important astronomical events can take place over a long period of time or in the blink of an eye. Astronomers need to do careful calculations and find a perfect place and time window to make and record these observations.

While the satellites follow a straight and predictable path in the sky, several thousand similarly bright satellites roaming the sky could be a colossal distraction for the stargazing and astronomy communities. Imagine a brightly lit train moving chaotically, why you are in a winter garden to quietly observe the behavior of lions.

SpaceX tried to fix the problem. she responded by redesigning the Starlink satellite outside, which makes all satellites launched afterwards – “DarkSats” – less reflective. They even published a paper proving that it was made the satellites noticeably darker.

However, Scientific American Reports that the change made little difference as the DarkSats are still bright enough to obstruct the survey of the sky by day or night. The updated DarkSats appear half as bright as the original Starlink fleet, the report said, which is an advance.

However, the streaks of light when traversing satellites are still a challenge for astronomers to continuously observe space objects and events.

University of Washington astronomer Meredith Rawls told the story SciAm If SpaceX continues without fixing the problem, it will set a precedent for other companies to follow suit and launch their own mega-constellations without considering the needs of the astronomy community.

If the problem persists, scientists may have no choice but to bring Elon Musk on his proposal to have observatories in orbit that are beyond the range of satellites blocking view.
