A satellite screw-up reaffirms Einstein’s
theory of gravity

This article is about two satellite who were send in orbit wrongly, so they
were traveling around the earth in ellipsis around the earth instead of
turning in round. It was not ideal for the research, but scientist decided to
used it to test the Einstein’s theory of gravity, the general theory of
relativity. According to him the relativity is that gravity also affects the time,
they give the example of a clock "So a clock at a higher altitude will tick
faster than one closer to Earth’s surface, where Earth’s gravity is
stronger." And they explained that the satellite time is increasing and
decreasing by second, but it is a confirmation of the general relativity within
a few thousandths of a percent the team report.
I wonder why the satellite was not in the right orbit but still turning around
the earth?
How the gravity can affect the time?
