WATER ON MARS ...& A SAPCE STATION ?

Hey guys anyone know anything about this space station on mars ? I have already seen that NASA has said it was an April fools joke (so why is the image still there ) ?
Also once I started looking around mars I noticed a lot of suspect things that shouldn't be there , Including what looks like a lake .
A close up shot of some hair & what looks like a man sticking his head out of a hole . Are these aliens or NASA hoaxes ?
If anyone has anymore information on these or has seen anything else that shouldn't be there please let me know .

Also if you have no idea what the hell I am talking about let me know and I will send you coordinates
