What are the 5 satellites that orbit earth all year at the same time everyday to photograph seasonal changes?

Question

PLEASE HELP!

or just five satellites that orbit the earth to photograph seasonal chanegs

Answer 1

This one's a thinker......
Either this is exceptionally specialized, or the question is flawed.
The sun, stars, and visible planets do not orbit the earth, so they're not the answer.
The moon does not orbit at the same time daily. It's out.
Manmade satellites in low earth orbit don't orbit at the same time every day. They're out.
The only thing that qualifies, that I can think of, would be geosynchronous satellites. When you can find the names of 5 geosynchronous satellites, then you're in business. I don't know anyone who knows that, but maybe you can find it online. But there's only one problem with that.......the geosynchronous satellites are so far out there's no way you're going to photograph them.
I think this question is flawed or a trick question or something.

Answer 2

I believe that you are talking about the Earth Observing System satellites. They are in a polar sun-synchronous orbit, so that they pass over the same part of the earth at the same time each day. Terra, Aqua, Hydros, Aura and Aquarius are the names of the satellites, if I remember correctly, but not all of them had the same mission (Hydros is supposed to measure soil moisture, for example) and not all of them are in orbit as of yet. With NASA's budget being cut I wouldn't be surprised if the project gets canceled. Terra, the first of the series put into orbit has 5 sensors designed to monitor the environment. I hope that helps.

Answer 3

There's a project by ESA called the cluster project.
Cluster is a collection of four spacecraft flying in formation around Earth. They relay the most detailed ever information about how the solar wind affects our planet in three dimensions.


not sure if this is the one ur looking for.
hope this helps!
