Hmmm, if nr 2 would be true, then the space shuttle would not be needing the heatshield for re-entering the atmoshphere?

We’ve discovered Marsquakes are a thing
While we’re used to having earthquakes here, and have found evidence of tremors on the Moon, Mars has always been thought of as a dead planet. With no geological activity or tectonic plates or magnetic field, it was assumed that Mars didn’t move.
According to the NASA InSight spacecraft, however, since November of 2018 to April of this year, there have been several tremors on the Red planet. This proves that Mars is still geologically active, which has huge implications for our future travels there.
