I don't know what it is. But it looks like a rock given that its texture and color are the same as the rock around it.

Its also highly unlikely that NASA would ever release any photo that confirmed aliens exist. While I don't know if they do or not, though I have my opinion, the reality is that Nasa has specifically avoided researching the most interesting leads for life outside earth. For example, its quite amazing that NASA chose not to investigate the so called "glass tunnels" of Mars, or the "face" on mars. Not that these are definitively of some alien origin, as they could be natural formations, but without checking (since modern observation has science still divided) - the debate will rage on. What about the pictures of Mars that appear to show forests at the poles? Do a search for trees on mars and take a look. A rover could go there and see - hey, are these some type of tree, or is it really a "dust" cloud as some theorize. We lack to tools to be sure from here - so sending a data gathering tool to the biggest question marks will provide better answers.

Yet Nasa avoids this. I for one would like to know why.
