Atmosphere Escape: Mars 3D Explorer vs Planet Atmosphere Scale Heights 3D Explorer
freetoolonline.com editorial teamBoth pages teach a real Mars atmosphere figure in one page load - 0 MB installed, USD 0, no account. The Atmosphere Escape: Mars 3D Explorer scrubs through time to show WHY Mars's atmosphere thinned out and HOW FAST it still leaks today; the Planet Atmosphere Scale Heights 3D Explorer slides through altitude to show WHAT five worlds' atmospheres look like right now.

Where the Atmosphere Escape: Mars Explorer wins
The Atmosphere Escape: Mars Explorer wins when the question is about CAUSE and TIME - it is the only page on the site that scrubs through billions of years to show a magnetic shield disappearing and an atmosphere escaping because of it.
Where the Planet Atmosphere Scale Heights Explorer wins
The Planet Atmosphere Scale Heights Explorer wins when the question is about STRUCTURE and COMPARISON - it lines up five worlds side by side at one moment in time, which the Mars-only, time-based explorer does not attempt.
A reasonable rule
As a reasonable rule, use the Atmosphere Escape: Mars Explorer first to see why Mars's atmosphere thinned out, then use the Planet Atmosphere Scale Heights Explorer to see how thin Mars's atmosphere is today next to four other worlds.
