It’s kind of sad how little attention that yesterday’s Mars landing is getting among the general population. The science involved in safely landing these robotics on Mars surface is unbelievably complicated and difficult. The lander has to hit the upper atmosphere at such a precise angle to be successful. If it’s too shallow it skips off. If it’s too steep it burns up. It has to slow its speed from 12000 mph down to 5 mph before it reaches the surface. NASA calls the trek from the upper atmosphere to the surface, “Seven Minutes of Terror.”

Unlike the previous rover missions, InSight will be stationary. It will be taking measurements to learn about Mars core. Our core is molten and spins creating the magnetic field necessary to protect us from the radiation of the sun. Mars core cooled and hardened at one point and after it lost its magnetic field the sun’s radiation stripped it of much of its atmosphere and water. But it is believed that before that Mars was much like Earth. This is why Mars is of interest to scientist...the possibility that evidence of prior life might exist.
Yet no one is talking about it.
