About that ‘mystery rock’ on Mars: no it’s not a plant, but…

There has been a lot of discussion the past few days about that lawsuit filed against NASA for supposedly covering up / failing to investigate evidence of life on Mars by the Opportunity rover. This all has to do of course with that “mystery rock” found by Opportunity, nicknamed Pinnacle Island, which somehow just appeared near the rover (most likely dislodged and kicked up by one of the wheels) a few weeks ago.

Curiosity plays in a Martian sand dune

Curiosity has also been taking a lot of close-up images of the sand dune which the rover has “toe-dipped” into. The rover’s wheels have left very distinct impressions in the very fine-grained sand within the dune, while the outside of the dune has a denser “crust” covered with many small rounded grains, similar to other dunes seen by the Spirit and Opportunity rovers. Whether or not Curiosity will actually drive through the dune (if deemed safe) to the other side of Dingo Gap or just go around hasn’t been decided yet, but in the meantime there are lots of new images to enjoy.

Dingo Gap has turned out to be quite an interesting place for the Curiosity rover, being both scenic and of great geological interest. Rocks of all sizes and shapes litter the landscape amid the cliffs and sand dunes and Curiosity is continuing to study this area before driving further south toward Mount Sharp. Another new panorama by Damia Bouic shows the scenery in stunning high resolution and there is also a great overview by Emily Lakdawalla on The Planetary Society blog.

New images: Dingo Gap and the ‘Firepit’

Curiosity is now doing a complete examination of Dingo Gap, and sending back some beautiful new photos. The rover team hasn’t decided yet whether to try to cross though the largest sand dune which spreads across the middle of the Gap, and is about 1 metre (3 feet) tall. The dunes, cliffs and many different broken and jumbled rocks here make this a very scenic location. Of particular interest also is the “rock ring” beside the largest dune, and also now nicknamed by some as the “firepit” (thanks to Bill Dunford of the Riding with Robots blog for that!).
