The best way to tell what type of siding is on your home, is to go to an unfinished area like the attic or garage, and pull back the tar paper from the back of the siding and look for markings. See if you can locate either the manufacturerâs name or AHA code (The American Hardboard Association).
The International Space Station (ISS) flies around the earth in a near circular orbit. The current altitude for that orbit is somewhere around 250 nautical miles. Given that altitude, the period, or time for one orbit is approximately 90 minutes...
Most scientific satellites, including NASAâs Earth Observing System fleet, have a low Earth orbit. One way of classifying orbits is by altitude. Low Earth orbit starts just above the top of the atmosphere, while high Earth orbit begins about one tenth of the way to the moon.(NASA illustration by Robert Simmon). The height of the orbit, or distance between the satellite and Earthâs surface, determines how quickly the satellite moves around the Earth.ost scientific satellites, including NASAâs Earth Observing System fleet, have a low Earth orbit.
