We did the work and found 54 missions cancelled in this proposal. This is another extinction-level event for NASA science. Full list: planetary.org/save-nasa-science 9290211

David Mimoun @moonnext.bsky.social · 16/12/2025Finally at #AGU25 ! Presentation of Philippe Lognonné of its network of telescopes to detect Moon impacts 050
David Mimoun @moonnext.bsky.social · 10/12/2025 Radiation is high, the drilling is deep, and the dust is relentless. But #planetaryscience is worth the trip 🔴✨ #Mars2040 ? 040
David Mimoun @moonnext.bsky.social · 10/12/2025Living off the Land (ISRU). Objective #6: We can't bring everything with us. We have to characterize the ice and regolith to extract water and make propellant. It’s high-stakes chemistry in a harsh environment - And here come the seismometers experiments 😉 150
David Mimoun @moonnext.bsky.social · 10/12/2025Objectives #7 & #10 Can Earth life reproduce there? We need to test if plants (and maybe model animals) can thrive and adapt over generations in 38% gravity. It’s about building a sustainable ecosystem, not just a campsite. Space farming ? 120
David Mimoun @moonnext.bsky.social · 10/12/2025The Human Lab. Objective #4 & #9: **We** are the experiment. How does the "Integrated Martian Environment" (radiation + low gravity + isolation + toxic dust) affect our bodies and minds? We need to survive the trip and the stay without breaking down physiologically or psychologically 120
David Mimoun @moonnext.bsky.social · 10/12/2025Dust, dust, everywhere. Objective #5 is crucial: What triggers those massive, planet-encircling dust storms? They mess with power, lungs, and hardware. We need to understand the physics of the atmosphere to predict when the sky will turn dark #MarsWeather 121
David Mimoun @moonnext.bsky.social · 10/12/2025Mars is a time capsule! Objective #3 focuses on the Geologic Record. As Perseverance did, we need to map the rocks to understand the transition from a wet, potentially habitable world to the dry desert of today. Impacts, volcanoes, ancient lakes the rocks hold the climate secrets of the solar system 120
David Mimoun @moonnext.bsky.social · 10/12/2025The Challenge: To find extant (living) life, we might have to drill DEEP. Like, kilometers deep below the cryosphere where liquid water might still exist. Getting pristine samples from 2-5km down while wearing a spacesuit? #DeepDrilling 120
David Mimoun @moonnext.bsky.social · 10/12/2025Priority #1: The big question. Are We Alone? The top objective is determining if Mars hosts (or hosted) life. We are looking for habitability, prebiotic chemistry, and actual biosignatures. The challenge: Distinguishing Mars life from Earth contaminants. 120
David Mimoun @moonnext.bsky.social · 10/12/2025The National Academies just dropped the Science Strategy for the first human campaigns on the Red Planet.
