NASA claim there are thousands of satellites orbiting the earth; it should be very easy for Neil Obstat to find a picture of a group of satellites in space.

Okay, so maybe it's not hopeless. You managed to put an "s" on satellites without losing control of the plural possessive apostrophe for a change.

Congratulations!

Now let's work on the number case of the verb "to claim."
.
You have "NASA claim there are thousands..." but the term NASA is not plural, it is singular. There is only one NASA, for example.
.
Therefore, you ought to have an "s" at the end of "claim" making into "claims."
.
Your sentence should have "NASA claim
s there are thousands..."
.
BTW I already posted a picture of several satellites in a group, but you're not paying attention I guess.
