#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

Ten laser blasts hit their sharp thin Martian rock target, and #Perseverance used LIBS, Raman, TRL, and VIS spectroscopy to analyze its composition.

Thin stony wedges¹, targeted by both the WATSON camera, located on the robotic arm turret, and the SUPERCAM telescope camera, located on the masthead.

¹ (for lack of a proper geological term, since IANAG)

«[T]he scientists found a shift in the spectrum of the absorption lines of water and carbon monoxide molecules, allowing them to deduce that they are blown by powerful winds»

Calculations indicated that the molecules were moving at a speed of 9 km/s, or 33,000 km/h on either side of WASP-127b’s equator.
