NASA curiosity took self photos to record the important moments of the probe

British media said that the National Aeronautics and Space Administration (NASA) announced the exciting selfie of the rover curiosity. This photo is actually composed of 57 individual photos, which are spliced together to record this important moment for the detector.

According to the website of the British Independent on October 25, this is the first time NASA has commanded curiosity to conduct chemical experiments in the etif valley of Mars, and it is also the second time it has completed such work.

In the photo, in front of curiosity, you can see two holes on the ground. The one on the right is named 'etif Valley 1' and the one on the left is named 'etif Valley 2'. By drilling these holes, curiosity can analyze the substances inside, turn them into powder and put them into its portable laboratory.

The experiment recorded in the photo took place on September 24, when the probe collected samples and put them into the Mars sample analyzer (SAM).

Sam lab has 74 small cups, most of which can be used to heat samples, so that the detector can identify the released gases and understand their composition. However, the new experiment uses nine small cups for 'wet chemistry' research, which can find carbon based molecules that form the cornerstone of life.

Then, curiosity can send these data back to earth, allowing scientists to select data to understand the ancient history of Mars and any life that may have existed there.

Because these cups are not many, researchers use them only when they are convinced that possible findings are important enough. This means that although curiosity has been on Mars since 2012, it did not conduct its second experiment after landing until last month.
