@Heliograph Thanks for posting that; I feel better about some literary choices. When I wrote my Mars novel I decided to use a single universal time for the entire planet. People can't live on the surface and most development is underground for radiation reasons. No windows. Some population is on spaceships or a station. One zone gives the same diurnal schedule to everyone everywhere. When they rarely need to use the surface, they use offset and solar terms, "like local dusk is just before lunch."

Did you know Elysium Planitia, a relatively smooth area on #mars had over 40 volcanic eruptions and massive floods that helped shape its landscape? Joana Voigt, Christopher W. Hamilton and Gregor Steinbrügge found these and more while studying the volcanic and hydrologic history of Elysium Planitia. Learn more from their findings at doi.org/10.25422/azu.data.2327 and doi.org/10.1029/2023JE007947. Image: Voigt et al. (2023).

Overview of the study site (black outline) in Elysium Planitia, which is a plains-forming unit in the Elysium and Aeolis quadrangles. Detailed study site (white outline) and major landmarks including the Elysium Rise, Medusae Fossae Formation, Aeolis Planum, Lethe Vallis, Amazonis Planitia, Grjótá Valles, Rahway Valles, Marte Vallis, Cerberus Plains, and Athabasca Valles are shown on a colorized Mars Orbiter Laser Altimeter (MOLA) hillshade. The light-colored beige polygon shows the amazonian-aged lava flows from this study. The InSight and Curiosity landing sites are marked with an orange and red star, respectively. Different segments of the Cerberus Fossae are marked with black lines with dots.

#Trump’s #budget proposal, though not yet formally submitted to Congress, would eviscerate a long list of #planetary & #astronomical missions, including the next major #NASA #space #telescope & the agency’s goal of bringing samples of #Mars back to Earth to search for signs of ancient life.

NASA’s #astrophysics budget would take a huge hit, dropping from ~$1.5B to $487M. Planetary #science would see a drop from $2.7B to $1.9B. #EarthScience would drop from ~$2.2B to $1.033B.

À l’œil nu : Mars s’aligne avec Castor et Pollux les 10 et 11 avril 2025

Mars s’éloigne de la Terre mais reste remarquable à l’œil nu. Suivez sa trajectoire parmi les étoiles et observez le bel alignement formé avec les deux principales étoiles des Gémeaux !
Simulation montrant le ciel du 10 avril 2025 à 22h (heure de Paris). La planète Mars est alors parfaitement alignée avec Castor et Pollux.

Meet the 25th Martian sample collected by NASA’s Mars Perseverance rover – “Sapphire Canyon” – a sample taken from a vein-filled rock named “Cheyava Falls.” The arrowhead-shaped rock contains compelling features that may help answer whether Mars was home to microscopic life in the distant past.

The Kid Should See This 🌈🪐✨

💁🏻‍♀️ ICYMI: Did you know planets without tectonic plates still experience "earthquakes"? It's fascinating how seismic activity works across our solar system. 🪐🌋

#Venus has volcanic tremors, while #Mars quakes as its core cools. #Jupiter's moon Io is our favorite example—with 400 active volcanoes, it's constantly shaking from Jupiter's immense gravitational forces pulling on its crust.

I doubt federal #MARS administrators can stick their oars in this water but maybe MARS volunteers can.

For those who want to know, what's MARS? It's this:

usarmymars.org/about-army-mars

and

acc.af.mil/Units/CCC/MILITARY-

if everybody has not already been fired.

Yes, "it's complicated." Maybe conflicted. A Cold War relic but like #EBS also having a higher purpose.

Anyway, mobilize MARS operators? Probably already in train.
