They become fainter as they are both moved to higher orbit as well as actively controlled to face certain directions–primarily for their own communication, but in part to make them appear dimmer, too. “Starlink’s appear very bright when they're first launched into low orbit-brighter than the great majority of naked-eye stars,” he says. While Starlink satellites in low-earth orbit aren’t the brightest man-made objects in the sky, it’s the sheer number of them that’s worrying, says James Lowenthal, professor of astronomy at Smith College. “Now, every direction you look there are a few moving above you. “You used to see a couple of satellites at the beginning of the night and it was very cool to see a ‘moving star’ in the sky,” Tafreshi says. SpaceX uses new satellites that can be folded up in the dozens and sent into space on private rocket launches out of Cape Canaveral in Florida and Vandenberg Space Force Base in California.

Satellites also make weather forecasting, TV signaling, radio, and military surveillance possible.īut before Starlink launches, there were no “trains of satellites” to be seen, says Tafreshi. Satellites like Starlink’s have long been used to enhance mobile services like cell phone coverage, internet and GPS navigation for people on Earth. Websites like predict when Starlink satellite trains will pass overhead for people looking to spot them. These satellites can be seen with the naked eye in the days following their launch (when their orbit is lower to Earth and satellites are still close enough together to appear in a line), and in the hours just after sunset and just before sunrise.

They aim to send up to 42,000 satellites into its mega constellation in coming years, according to . SpaceX did not respond to National Geographic’s request for comment.

In a February press release, SpaceX said they’d launched “nearly 4,000 satellites” over the last five years. Satellites: an invaluable tool, an astronomic obstacle “That’s when there were only 1,500 Starlink satellites…Now there are three times that amount.” And many more are on the way. So when one of these streaks goes across the image, it completely obliterates the image.”Īt least 6 percent of the 2021 images from the Hubble Space Telescope were “compromised or completely ruined” by satellite interference by Starlink satellites, he says. “The objects we’re trying to study–distant galaxies and stars–are 20 million times fainter than satellites. “When a satellite goes through the field of view of a telescope, it’s extremely bright,” Helfand says. The satellites are making it much more difficult for astronomers to do their jobs, he says. Helfand, a professor of Astronomy at Columbia University. Sightings of Starlink mega constellations are also becoming more common, says David J. In recent months, these satellites are being launched more frequently, often with over 50 satellites at a time, by Elon Musk’s commercial space company.
