The FY 2027 NASA budget request hides its science cuts by omitting mission names instead of explicitly zeroing them out. 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

Radiation is high, the drilling is deep, and the dust is relentless. But #planetaryscience is worth the trip 🔴✨ #Mars2040 ?

David Mimoun @moonnext.bsky.social · 10/12/2025
Living 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 · 10/12/2025
Objectives #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 · 10/12/2025
The 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 · 10/12/2025
Dust, 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 · 10/12/2025
Mars 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

The 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

David Mimoun @moonnext.bsky.social · 10/12/2025
Priority #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.
