The #Starship Human Landing System could be vulnerable to ground acceleration from nearby #moonquakes that would threaten their stability. Short-term missions, such as #Apollo, were relatively low-risk, but longer-duration projects face incrementally higher exposure https://cmns.umd.edu/news-events/news/nicholas-schmerr-helps-identify-moonquake-dangers

U. of Maryland Geophysicist Helps Identify Moonquake Dangers that Could Threaten Future Missions

A new paper revealed that ground acceleration from moonquakes, rather than meteor impacts, was responsible for shifting lunar landscapes at Taurus-Littrow valley, where Apollo 17 landed in 1972.

#PhotoOfTheDay: #Moonquakes Surprisingly Common

Analyses of seismometers left on the moon during the Apollo moon landings reveal a surprising number of moonquakes occurring within 100 kilometers of the surface.

Pictured here, Apollo 11 astronaut Buzz Aldrin stands beside a recently deployed lunar seismometer, looking back toward the lunar landing module.

@lienrag Sure. What kind of wacky aspects do you have in mind? That an exoquake may split the planet in half?
Recalling analyses of #moonquakes:
https://www.nasa.gov/exploration/home/15mar_moonquakes.html
and #marsquakes:
https://en.wikipedia.org/wiki/Marsquake
they are exceptional by 1) typically shaking longer (more scattering) and 2) more often being meteoroid impacts (thinner atmosphere).

Quite impressive: a #sunquake can reach magnitudes >11—impossible on earth.
