Otis Peak (Sample 20) – NASA Mars Exploration

November 14, 2023

Meet the twentieth Martian pattern collected by NASA’s Mars Perseverance rover – “Otis Peak,” the primary rock core pattern taken from a conglomerate rock, which consists of pebbles cemented collectively.

This pattern is known as a “treasure field” as a result of the pebbles are believed to have been carried by a fast-moving river from locations the rover might by no means discover. Scientists imagine learning this pattern might yield details about the formation and environmental evolution of Jezero Crater.

As of early November 2023, the Perseverance rover has collected and sealed 23 scientifically chosen samples inside pristine tubes as a part of the Mars Pattern Return marketing campaign. The following stage is to get them to Earth for research.

Thought-about one of many highest priorities by the scientists within the Science and Astrobiology Decadal Survey 2023-2032, Mars Pattern Return could be the primary mission to return samples from one other planet and supplies the most effective alternative to disclose the early evolution of Mars, together with the potential for historical life. NASA is teaming with ESA (European House Company) on this essential endeavor.

A key goal for Perseverance’s mission on Mars is astrobiology, together with the seek for indicators of historical microbial life. The rover will characterize the planet’s geology and previous local weather, pave the best way for human exploration of the Purple Planet, in addition to be the primary mission to gather and cache Martian rock and regolith (damaged rock and dirt).

MARS ROCK SAMPLES

SAMPLE 20: OTIS PEAK

TYPE: SEDIMENTARY

LOCATION: EMERALD LAKE, UPPER FAN

GEOLOGIST & SCIENCE OPERATIONS – MARS PERSEVERANCE ROVER

Samantha Gwizd: Pattern 20 known as “Otis Peak,” and we collected it from a rock known as “Emerald Lake” on the Higher Fan.

Emerald Lake is admittedly fascinating as a result of it’s our first conglomerate pattern, which is a rock that consists of pebble dimension grains cemented collectively.

STEVEN SHOLES

SYSTEM OPERATIONS, RESEARCH SCIENTIST – MARS PERSEVERANCE ROVER

Steven Sholes: These are a lot of little pebbles from rocks that had been collected all all through the Jezero Crater watershed. So that is means outdoors the place the river is and all these pebbles are well-rounded. What well-rounded means is that this stuff traveled far and since they’re bigger, we all know that this was a excessive power surroundings. Which signifies that the water was flowing a lot sooner and so it is capable of carry bigger sediments to kind these conglomerates.

There’s the potential we are able to truly take these again to Earth and analyze every particular person pebble to grasp what these totally different rocks are that shaped. And you’ll form of piece collectively a broader spectrum of what this space outdoors of Jezero Crater was like.

Samantha Gwizd: This pattern is sort of a actually cool treasure field as a result of we might or might not ever be capable to encounter these sources with the rover. And so this provides us a glimpse into another actually fascinating rocks and their historical past.
