THAT'S A MOUSE
Prove it.
There is no justification for that claim at all.
You need more evidence of NASA's "credibility?"
Here we go :


NASA DESTROYED AGAIN (Small Mammal (rodent) On Mars) :
Yep, still no justification. You've moved on from sliding ice on a rocket cowling to a rock on Mars. And the video maker so helpfully colorized the rock with a squirrel tint. Anything to sell the idea I suppose. Sprinkle in a smidge of pareidolia and you've got viral gold. This is just getting more an more pathetic by the minute.
NASA DESTROYED AGAIN (Greenland portrayed as Mars) :
In this piece, Jared shuffles around photos and makes it seem like after his extraordinary "digging" he has stumbled upon the fake NASA Mars. When in actuality, he's just looking at the Haughton Mars Project (HMP), Devon Island, Canada. It's no secret like Jared makes it out to be. From NASA:
"HMP is part of a research facility located on the world's largest uninhabited island, Devon Island. This harsh climate mimics the environmental conditions on Mars and other planets. Devon Island's barren terrain, freezing temperatures, isolation, and remoteness offer scientists and personnel unique research opportunities. Arctic day and night cycle and restricted communications capabilities offer fitting analogs for the challenges of a long-duration space flights.
Research: In addition to communications, equipment testing, and vehicular and extra-vehicular operations, Devon Island is the site of the Exploration program, which aims to develop new technologies, strategies, and operational protocols to support the future exploration of the moon, Mars, and other planets."

As for the rover spotted, again, no mystery. From the NASA site:

Now, what about Challenger?
