NASA's Spirit rover took this photograph of the surrounding hilly terrain, as well as several rocks. The two light-coloured, smooth rocks at the bottom of the picture might be iron meteorites. Mission controllers have named them "Zhong Shan" and "Allan Hills". Spirit uncovered that the rocks have unusual morphologies and thermal emission spectrometer signatures that resemble a rock called "Heat Shield" discovered by Opportunity, and later identified as an iron meteorite.

I'm wondering how I read about this June 11 (and posted (http://www.bautforum.com/showthread.php?p=760141#post760141)), when the Planetary Photojournal put up a picture (http://photojournal.jpl.nasa.gov/catalog/PIA08529). I guess NASA finally got around to writing a press release a month later.

To be fair, additional imaging and measurement has been done on the objects, so maybe they are more likely to be right about their surmise that they are meteorites, and got the courage to write it up.

Why is the sky white ? It is an approximately true-color image! Or am I getting crazy and the sky is really white =]

Don't count on the Mars Rover color images being true color.

Now I just wish I could find meteorites around my backyard as easy as the rovers can. They both found several of them just lying around on the ground. Way cool!

Better?

The picture in the article is not the approximate-true-color picture to which the text refers. It is the false-color version:
