What this reel claims
Mars
01
Mars has an extremely thin, carbon-dioxide-dominated atmosphere with surface pressure below one percent of Earth’s.
02
Ancient Mars held rivers and lakes, and the loss of its global magnetic field left the atmosphere exposed to long-term erosion.
03
MAVEN observations published in 2025 directly detected present-day atmospheric sputtering at Mars.

What didn’t fit
What didn’t fit
Evidence for ancient rivers and lakes is strong, while a global ocean remains model-dependent; losing a global magnetic field also does not mean the entire Martian core froze.
