Analysis of Mars surface samples highlight potential ancient water bubbles

Following an unsuccessful sample collection attempt in early August, NASA’s Perseverance Mars rover has successfully drilled, collected, sealed, and stored two separate Martian surface samples. Both sample collections took place in the same week.  Additionally, new data from the samples show that the rock collected is likely volcanic and may contain bubbles of ancient water. Perseverance’s first successful samples In early August, Perseverance attempted to collect a sample from a rock located at the “Cratered Floor Fractured Rough” area in Jezero Crater. The rover successfully drilled a hole into the ground, but upon inspection of the sample tube, no surface sample was found.  Scientists and rover engineers studied the issue, concluding there was no sample in the tube due to the rock being too “crumbly” and breaking into pieces too small to stay inside the sample tube.  After the first sample attempt, Perseverance drove 455 meters to a ridge named Citadelle, a capped-off layer of rock that seems to resist wind erosion — indicating that Citadelle was likely to hold up during a sampling attempt.  Once the rover was at Citadelle, Perseverance teams scouted the area for a rock that appeared suitable for sampling. They settled on a rock named…
