NASA and SpaceX are now developing a plan to determine if such a thing is possible.Įarlier we reported that SpaceX launched the first batch of the next generation Starlink.This image from the NASA/ESA Hubble Space Telescope captures the spiral galaxy NGC 105, which lies. An effective solution may be a significant increase in the orbit of the space telescope, which has declined sharply for decades. Hubble is currently operating at an altitude of about 540 km above the surface, which is about 10 km lower than some of the tallest Starlink satellites. Unfortunately, these methods were not very effective. For example, they used dark paint or visors to reduce the reflective properties of the surface. SpaceX has already experimented with some methods to mitigate the impact of Starlink on astronomy. For example, reduce the display of their satellites. In this Hubble telescope image, three distinct stripes are visibleĪstronomers are also asking satellite operators to do something on their part. However, the additional time for restoration and the cost of astronomical research will only increase. According to NASA, most of the images are still usable. Attempts to solve the problem for HubbleĪt the same time, astronomers are not completely helpless, as they can apply various data and filtering techniques to identify and salvage ruined images. The international community has asked the United Nations for help in setting up an expert group on this issue. The analysis stopped in 2021, but two years have passed since then, and the situation is much worse now.Īstronomers are trying to prevent the situation from getting worse. The algorithm was trained to detect images corrupted by satellite bands and ignore similar traces caused by natural phenomena such as asteroids, gravitational lenses and cosmic rays. Scientists used an artificial intelligence algorithm to analyze more than 100,000 individual images as part of the Hubble Asteroid Hunter project. A very large satellite band appearing in this image from Hubble By that time, there were 1,562 Starlink satellites in orbit and 320 from OneWeb. Deterioration of the situationĪ study led by Sandor Kruk of the Max Planck Institute for Extraterrestrial Physics in Germany found that 3.7% of Hubble telescope images taken from 2009 to 2020 were corrupted by satellite bands. A study published this week in the journal Nature Astronomy shows the extent of the impact of the growing swarm of satellites on the Hubble Space Telescope. The situation is so serious that scientists have declared satellite constellations an existential threat to astronomy. The space fleet of Starlink and OneWeb satellites exacerbates the problem every year, clogging the field of view of telescopes by creating unpleasant stripes on astronomical images. Take into account the thousands of satellites currently operating in orbit, and you will be able to quickly assess the problem. Satellites in low Earth orbit orbit the Earth every 90 minutes. Hubble photo ruined by Starlink satellite bands New research shows that space telescopes like Hubble have started to suffer from them too. The ever-growing number of SpaceX Starlink satellites is creating problems for ground-based astronomy.
