Scientists calculate it is too massive to have hit the ground without disintegrating unless Mars had a much thicker atmosphere than it has now when the rock fell. Atmosphere slows the descent of meteorites. Additional studies also may provide clues about how weathering has affected the rock since it fell. </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://spaceflightnow.com/news/n0908/11meteorite/"><div align="center"><img src="http://content6.clipmarks.com/blog_cache/spaceflightnow.com/img/C6D37A2F-2E5D-427B-8C0B-6BCCBB51DB08" alt="" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://spaceflightnow.com/news/n0908/11meteorite/"><FONT size="-2" face="Verdana, Arial, Helvetica, sans-serif">Opportunity used its microscopic imager to get this view of the surface of Block Island.
