These two things are, however, very closely related, because the job a satellite does usually determines both how far away from Earth it needs to be, how fast it has to move, and the orbit it has to follow. The three main uses of satellites are: Communications Photography, imaging, and...
Also, if there are dense objects between the satellites and the dish (buildings, trees, mountains), it will greatly interfere with the signal. When first installing and setting up your satellite internet, positioning is key to getting the best speed and reliability. It begins with ...
But at altitudes of 600 km—where the International Space Station orbits—satellites can stay up for decades. And that’s potentially a problem. They travel so fast—5 miles a second—that their “footprint” can be hundreds of miles long. “When you think of them as being that big, ...
You can also see the moons of Jupiter (Galilean satellites) -- Io, Europa, Callisto and Ganymede. The moons orbit Jupiter in changing positions each night, and they are interesting to watch over the course of many days. In a large telescope (8- to 10-inch or 20- to 25-cm reflector)...
On February 8, 2022, approximately 40 of the 49 Starlink satellites were reported to have lost altitude, leading to atmospheric re-entry. SpaceX reported that the orbital decay on Starlink satellites was considered to be linked to a geomagnetic storm tha
Satellites are now used as well, but they suffer from many of the same problems. Scientists do the best they can, using extremely long time spans, to try to figure out what the sea level is and whether or not it is rising. The general consensus seems to be that the oceans rise about...
Starlink satellites travel very fast and completeone orbit of Earth every 90 minuteswhich means you can sometimes see them within just two hours of a previous sighting. Can you spot Starlinks when they deorbit? If Starlink satellites fail to make orbit, they then return toEarthin dramatic fashi...
Additionally, the ISS monitors the whereabouts of various stars, satellites and ground stations — as well as the sun — in order to navigate [source: NASA]. Now that you know how the ISS stays in space, let's see what it's like to live and work there. ISS Communications To stay in...
Map something: Space shuttles and orbiting satellites use something called synthetic aperture radar to create detailed topographic maps of the surface of planets and moons. All three of these activities can be accomplished using two things you may be familiar with from everyday life — echo and Do...
