Satellites in a sentence

Common types include military (spy) and civilian Earth observation satellites, communication satellites, navigation satellites, weather satellites, and research satellites.

In-Orbit Validation (IOV) satellites These testbed satellites were followed by four IOV Galileo satellites that are much closer to the final Galileo satellite design.

Aside from inspecting the three satellites’ firmware, the researchers also conducted a survey of 19 professional satellite engineers and developers who collectively work on around 132 satellites.

In 2022, Astra launched its first customer satellites and sold spacecraft engines that will power a number of new constellations of small satellites in lower orbit.

LEO hosts important satellites such as the Hubble Space Telescope, the Copernicus Sentinel Earth observation satellites, and the International Space Station.

OneWeb has more than 600 satellites in orbit while SpaceX’s Starlink constellation is approaching 5,000 satellites in orbit.

OneWeb only needs 588 of its 648 proposed satellites operating in LEO to provide global services, and any satellites launched beyond that point would serve as backups.

SpaceX began launching satellites into the Gen2 network in December, beginning the population of new orbital planes with older-design satellites until the larger Starlink spacecraft design is ready to take over entirely.

There were 1,562 Starlink and 320 OneWeb satellites in orbit at the time, “increasing the population of satellites close to the orbit” of Hubble, the scientists write.

Unlike satellites kept in low Earth orbit, these satellites are not intended to return to Earth at the end of their life.

Before Gen2 satellites were ready, SpaceX pointed out that it could put additional Starlink satellites into orbit faster and more cheaply than Russia or anyone else could destroy them.

China and Russia are both operating satellites that attempt to better understand high-value U.S. government satellites.

However, information for Gaofen satellites numbered 8 and above has not been openly released, suggesting the satellites are for national defense purposes.

SpaceX already had approval to launch 7,500 second-generation satellites for its existing broadband service, and the new approval allows mobile service from those satellites.

The first thing is that the satellites are all in place, so we now have the 650 satellites circling where they need to be.

The Lunar Pathfinder satellite, designed by Surrey Satellites, is set to launch in 2025 with the aim to then launch a constellation of satellites in lunar orbit from 2028.

The satellites entered low-Earth orbit less than an hour from liftoff, joining Starlink's existing fleet of satellites providing wireless Internet service around the globe.

These exchanges, he says, would be “making sure that satellites do not accidentally bump into other satellites, in Earth or lunar orbit.

We rely on satellites for early warning of an enemy attack, for communications of all sort, and—through a network of GPS satellites—to guide “smart” bombs and missiles to their targets.

And although today most of the images come from satellites owned by the U.S. and European Union, more may soon come from satellites operated by developing countries — including Ethiopia's first observatory satellite, launched in late December.
