NASA uses ground-based telescopes to hunt for potentially killer asteroids. But NASA is worried that second-generation Starlink, which could begin launching as soon as this month, could someday contribute to ending life on Earth as we know it. “But in the current situation, when we really need internet connectivity, that’s starting to be more important.”įor Kutkov and other Ukrainians, Starlink is a lifesaver. “I was 100% with astronomers,” Kutkov said. Kutkov said he used to side with astronomers like Lawler in thinking that the concerns about Starlink impeding observations of the cosmos outweighed its benefits, but Russia’s invasion is changing his mind. Should we hide, should we not hide? Can we go outside or not?” Kutkov said. “We are getting all the information from the internet about airstrikes, about enemy force movements. But when Russia invaded in February, Elon Musk activated Starlink service over Ukraine, and Kutkov has been using it as his backup internet service ever since. Oleg Kutkov is a Ukrainian engineer and amateur astronomer who bought a Starlink terminal on Ebay in December to take apart for fun, never thinking he’d actually be able to use it in his apartment in Kiev. Rare NASA lunar dust collected by Neil Armstrong on the Apollo 11 mission is up for auction Particles of lunar dust are up for auction later this month and valued at up to $1.2 million. While thousands of small Starlink satellites are problematic for astronomers, they’re also providing much-needed internet access to people in rural or war-torn parts of the world. Other distant competitors include Amazon’s Project Kuiper and London-based satellite company OneWeb. SpaceX has already launched more than 2,000 satellites with plans to launch at least 42,000 more for its mega-constellation called Starlink. It’s the dawn of mega-constellations, tens of thousands of small satellites only about 300 miles (483 kilometers) above Earth, launched by private companies to provide global high-speed internet access.Įlon Musk’s SpaceX is responsible for roughly a third of all active satellites in orbit, more than any other company or country, including the US government. So that’s kind of the transition that we’re going through with satellites in the night sky right now.”

“But now you live next to a giant freeway, full of cars. A Model T would drive up the road and you’d run out to go look at it,” Lawler said. “It’s kind of like we’re going through this transition (similar to) when the first cars were on the roads.
Unless something changes dramatically in terms of international regulation of satellite numbers, reflectivity and broadcasting, experts like Lawler believe that impact on astronomical research will intensify. The satellites are even more disruptive when viewed through a telescope, and they’re already contaminating images of the cosmos captured by observatories all over the world. “There’s only about 4,000 stars that you can see with your naked eye and if 200 of those are moving, that is very different than the sky that we’re used to now.” Lawler and two other Canadian astronomers published a paper in December in The Astronomical Journal which predicted that, in less than a decade, 1 out of every 15 points of light in the night sky will actually be a moving satellite. “It’s changing fast.”Īnd it’s about to get much worse. “This is a lot worse than I expected,” Lawler told CNN.

Reduces map update error rates four-fold.Pictured is the Starlink Satellite Overpass, taken in Piedras, New Mexico, on March 22, 2020.
