The United States Geological Survey (USGS) and National Aeronautics and Space Administration (NASA) -run Landsat 8 Low Earth Orbiting (LEO) imagery satellite’s primary job is to take pictures of the Earth. But occasionally, like teenagers with new camera phones, Landsat 8 feels compelled to take pictures of other satellites. Really—you can see the evidence here […]Read More Pictures of a Decaying Satellite
For a very long time, satellites orbiting the Earth have had a very finite lifetime. Some satellites have lasted over ten years, and aside from anomalies and failing components, a satellite’s fuel tank has been key to how long a satellite can function. But that might change soon for geosynchronous (GEO) satellites, thanks to RROxITT (Remote Robotic […]Read More Fill it up, RROxITT! And check the solar panels, too.
All that you touch, all that you see… Yep, you guessed it! We’re going to talk about another issue common to geostationary (GEO) satellites: the eclipse. This issue is almost opposite from the problem discussed in Part 5 of the GEO lesson series. Instead of being overpowered by the sun’s energy, the satellite can’t function […]Read More Why Space Matters: GEO Satellite operations, Part 6–Eclipse
Womencitizen is focusing on the Earth’s “Love Handles” with this 2 February post. University analysts are finding the odd shape of the Earth is keeping satellites in orbit longer than if it were a perfect sphere. If you’ll remember, the Earth isn’t shaped like a perfect sphere, but more like a squashed Halloween pumpkin. Such […]Read More The Earth’s “Love Handles”
During the last few lessons, the great advantages of satellites in a geostationary orbit (GEO) were espoused about ad nauseum. The characteristics of persistence in communications and observations are the direct benefits of using a satellite in GEO. Include the huge field of regard and simplified ground system requirements, and it’s really a no-brainer to […]Read More Why Space Matters: GEO Satellite operations, Part 5–Lights & Music
