Collecting samples on another planet isn't as easy as it looks.
to carry them to Earth in 2033, allowing scientists to apply the most powerful lab technology to study the molecular structure in greater detail and determine whether the organic molecules have biological origins.
The life-hunting rover is equipped with a suite of onboard instruments to understand mineralogy and elemental distributions, as well as to detect whether organic molecules are present. At the most promising rocks, Perseverance then attempts to drill a core sample to put in one of its collection tubes.
However, choosing a rock that is just right to sample can be challenging for the robotic explorer. Sometimes, the coring process alone can cause the fragile rock samples to fracture, crack or even"The rocks here at the ancient river delta are amazing, but so far none has been perfect for #SamplingMars.
Perseverance ran into this issue when attempting to sample what scientists nicknamed"Betty's Rock" — a layered rock located near the bottom of and composed of alternating coarse-grained and fine-grained materials. Unfortunately, the rover was unable to safely maneuver the jagged layers and awkward shape of this rock.
