One of NASAs satellites orbiting Mars has looked back home to record a Martians-eye view of the Earth and moon from 127 million miles (205 million kilometers) across the solar system.

Think of all the women on Earth who just got upskirted by this photo...how creepy
My point exactly.
At least you weren’t sunbathing nude in your backyard (hat tip to Homer Simpson.)
As long as you’re not trying to get things from earth to not earth sure, whatever frame of reference you want. As soon as you’re trying to get things to somewhere else though the reality that we are very much not fixed matters a lot.
Earth is not an inertial reference frame.
Albert Einstein said almost precisely that in his theory of general relativity, it all depends upon frame of reference; the one is no more valid than the other. Of course, observing this will earn you all manner of wild accusations of being somehow unscientific.
Yes I have and used it in “friendly” argument with various people. It should be emphasized more. Frames of reference are good enough for Einstein after all.
I see my house.
But it is a perfectly correct frame of reference and much better than all others I can think of. Where else is there proven intelligent life?
“When did Earth start orbiting Mars?”

An anonymous CIA source reports that the Russians initiated this to help Trump get elected. Tune into CNN for details.
What do you mean by that? I'm familiar with the term "inertial reference frame"; it has a specific meaning in Newtonian mechanics and an equivalent meaning in both special and general relativity.
Where else is there proven intelligent life?
What is the relevance of proven intelligent life to defining a frame of reference for the universe?
Its resolution is one microradian, or about 0.2 arc seconds. Its image sensor is an array of line-scan CCD arrays, with a total aggregate width of many thousands of pixels (the exact number depends on the wavelength of light being detected). Because it uses line-scan sensors, HiRISE's transverse resolution is unlimited; it is scanned by moving the entire camera, which normally happens as a result of the orbital velocity of the Mars Orbiter satellite.
Under normal circumstances, each pixel of HiRISE corresponds to a square about one foot on a side when projected onto the surface of Mars.
It was conceived by Alan Delamere of Ball Aerospace, and designed by Mr. Delamere and Professor Alfred McEwen of the University of Arizona. From idea to launch took about twenty years.
Alan Delamere was described by one of his colleagues as "radically creative."
Ball Aerospace is a division of Ball Corporation, the same company that makes Mason jars.
That our Earth is objectively rotating is indisputable, supported by much evidence including Coriolis effect, etc.
Look at those crazy Australians ... standing upside down ...
You are joking right? Intelligent life is all that gives any frame of reference any meaning at all.
