SpaceX launched Starlink satellites on a pair of Falcon 9 rockets eight hours apart from opposite coasts on July 13-14, 2026. The second launch was the 600th use of a flight-proven booster.

SpaceX is currently ahead of last year's record-setting pace for Starlink satellite deployments. SpaceX launched 1,589 Starlink satellites into low-Earth orbit in the first half of 2026, according to launch data compiled by Jonathan McDowell's satellite tracker, compared to 1,489

For decades, astronomers and policymakers have been working on plans to protect our planet from killer asteroids. But now there's a new realm to protect: the thousands of satellites we're putting in orbit.

When a bright fireball streaked across the Alaska sky last spring, the usual tools scientists rely on to track such events—cameras and satellites—did not provide a detailed picture. But the meteoroid left behind something else: low-frequency sound waves that traveled hundreds of

Seventy years ago, Earth had only one satellite: the moon. Now it has more than 15,000—about 10,000 of which are owned by Elon Musk's SpaceX. The world's first trillionaire plans to launch 1 million more satellites, each roughly 70 meters (230 feet) long and 20 meters (66 feet) w

The 1.7 million satellites that companies are aiming to launch into Earth's orbit in the coming years will have "devastating consequences for astronomy," new research warned Wednesday.

The summers of 2021 and 2022 were tough seasons for Colorado's Blue Mesa Reservoir. A severe drought gripped much of the western U.S., prompting emergency water releases that brought the reservoir to its lowest level since 1984. Marinas and boat ramps closed, remnants of a ghost

From mobile phones and banking systems to aircraft, ships and emergency services, much of modern life relies on precise timing signals from satellites. Known as the Global Navigation Satellite System (GNSS), satellites carrying atomic clocks transmit time-stamped signals to recei

A new scientific review outlines how satellites and other remote sensing technologies are increasingly shaping how biodiversity and ecosystem health can be monitored at scale—offering new opportunities for countries reporting under international nature targets, while also undersc

We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings—at least as long as we're not sending them 500-plus AU away to a gravitational lensing point. We've also talked at length about th

A newly discovered underwater volcanic eruption north of Papua New Guinea is unfolding in one of the world's most poorly mapped ocean basins. Satellites have spotted steam plumes, ash, thermal hotspots, and huge floating pumice rafts, suggesting magma is rising surprisingly close

Evidence of the slowing of Charon's spin period (despinning) is recorded in tectonic features on the surface of Pluto's icy moon, according to a modeling study published in Nature Communications. The findings offer insights into the early thermal evolution of Charon and other icy
