00:02Sample 24 is called Comet Geyser and we collected it from the Bunsen Peak rock on the margin unit.
00:08The Comet Geyser sample is really exciting for several reasons.
00:12This rock is dominated by silica and carbonate.
00:15These phases are known on Earth to be good at preserving biosignatures.
00:20Carbonate is a phase that forms an association with fluids such as water,
00:25which is really important in our search for evidence for past life on Mars.
00:30It's still a bit of a mystery what this rock is.
00:33There are interesting textures that could be consistent with either an igneous rock or a sedimentary rock.
00:40And that's what makes it so exciting to us as scientists is because we get to put our thinking caps
00:45on
00:45and really try and solve this puzzle.
