A new study published in The Innovation highlights the launch of Haishao-1 (HS-1), China's first low-inclination orbit ...

Operators lost contact with the MethaneSAT satellite on 20 June, a significant blow to efforts to track – and stop – methane ...

Geosynchronous orbits are vital for communications and Earth-monitoring satellites. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. A ...

A giant slingshot might sound like something out of a science fair or a medieval battle—but one California startup is turning ...

This is by far the biggest effect, and this is the reason that low-Earth orbits are so unstable. Other satellites -- like geosynchronous satellites -- will decay as well, but not on such short ...

Unfortunately, satellite orbits change with time, and this means the mathematics needed to determine when you can see a given satellite goes far beyond simple geometry.

This image shows the first 60 Starlink satellites launched into orbit on May 23, 2019. ... That includes minimizing the amount of time prior to raising satellite orbits to their final altitudes, ...

America's spy satellites are not in the orbits that Pentagon says they are. According to a respected space analyst there are several discrepancies in the data held by the UN - who maintains a ...

Starlink satellites have operational orbits of 340 miles (550 km), which is above the most at risk region. However, after launch, Falcon 9 rockets deposit the satellite batches very low, only ...

He’s observed that batches of satellites will ascend to operational orbits in groups, taking advantage of what’s known as plane drift, to cover different parts of the globe with a single launch.

Up until about a decade ago, an average of 80 to 100 satellites per year were launched into varying orbits. Some reentered Earth's atmosphere quickly, while others will remain in orbit for decades.
