While #Artemis2 is minutes from launching to the Moon after 54 years, #Perseverance sends its good luck wishes with the image of a rock.

… but on Mars, it's just Tuesday.

A 4cm stone about 3.7m away seen through #Perseverance's telescope.

In a similar situation #Curiosity had crashed pure yellow sulfur with one of its wheels. This crashed rock isn't yellow.

#Perseverance turned its SUPERCAM telescope *again* on that very interesting stripped feature it had examined almost a week ago: https://mastodon.social/@65dBnoise/116231068516638183

A very interesting closeup of a rock next to #Perseverance, showing some intriguing curved stripes. Millimeter scale.

I often and loudly express my disappointment for posts appearing on websites of scientific institutions that are thin in or lack scientific content. A recent paper by Cornel researchers called similar texts "corporate BS".

Here is a short scientific post, containing pure information for people with a scientific background or interest in space and science.

Maybe assigning a Signal-to-Noise-Ratio (SNR) to posts and articles could help implement a BS filter?

This post's SNR: ∞ dB
