The measurement of the ingenuity reveals the surprising wind speed of Mars.
NASA’s creative helicopter this view was generated on August 2, 2023 using data collected by Mastcam-Z on a MARS Rover, which is a distributor. Credit: NASA/JPL-CALTECH/ASU/MSSS One of my dissatisfaction in the “The Martian” movie was the depiction of the wind of Mars. Low air density means that high -speed type of high -speed winds that can be experienced on…

X-ray diffraction enables in-situ ablation depth measurement in aluminum
Credit: Pixabay/CC0 Public Domain When laser energy is applied to a target material, a number of complex processes occur over length and time scales that are too small to be observed visually. To study and ultimately fine-tune such processes, researchers turn to computer modeling. However, these simulations rely on accurate equation of state (EOS) models that describe the thermodynamic properties…
