This is an interesting little bit of something that showed up in the scoop mark left behind when they took a scoop of Martian soil with Curiosity.
One can only speculate on what that is. A white mineral in the soil? A piece of bone, or tooth, or shell? NASA is only saying that they believe it is native to Mars and not something that fell off the craft.
They say it’s a Mars rock with an interesting coating… Maybe… If I saw this here on Earth I’d say, hey a piece of petrified wood.
I started this blog on Blogger.com. Google ate it and discontinued FTP Publishing. They offered two replacements, neither of which worked because they’d require me to host on Blogger.com which would force me to change the location of my blog and leave me at the mercy of Google who could discontinue anytime they don’t approve of my content. Not acceptable!
Now this is using WordPress on my own site. The downside is that any videos I had didn’t make it across the import process. So some cool stuff is gone.
