But if you’d like to avoid Facebook you can fill out their web interest form.
If you look closely at the full image, you can see a row of tiny circles indicating where the rover fired its laser, from the SuperCam instrument, in order to learn more about this interesting green rock which is around six inches long. It’s definitely something I’d add to my collection if I had a chance!
