New research shows the alarming degree to which Hubble images are being ruined by satellites passing through the telescope’s field of view.
. That satellite swarms are having a detrimental effect on space-based astronomy is obviously not good.“We’re going to be living with this problem. And astronomy will be impacted,” Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics,the New York Times in reference to the new study. “There will be science that can’t be done. There will be science that’s significantly more expensive to do. There will be things that we miss.
Astronomers, in an attempt to prevent the situation from getting worse, have been organizing and agitating accordingly. In the most recent development, anIn the meantime, astronomers aren’t completely helpless, as they can apply various data and filtering techniques to identify and potentially salvage spoiled images.
And as NASA told the New York Times, “the majority of affected images are still usable.” This said, the added time and cost toAstronomers are also asking satellite operators to do their part, such as making their satellites less reflective. In response to such requests, SpaceX has been experimenting with some mitigation techniques for Starlink, such as using dark paint to absorb sunlight. Unfortunately, this particular “mitigation was less effective than desired,”to SpaceX.
have proven to be “highly effective,” the company claims. SpaceX is also experimenting with “dielectric mirror film,” which directs light away from Earth.Hubble is currently operating some 336 miles above the surface, which is roughly 6 miles lower than some of the highest Starlink satellites. A solution might be to significantly raise Hubble’s orbit, which has shrunk dramatically over the decades.
