They got to the new village, and the new labs they found there were spectacular! Although there were only three labs so far, their use could surely be adequate.
There was a medical lab, right above all those living areas, and it might be the most important component of the base, as it promised longevity.
This lab/room was close to the people, which further promised survival. It was built just above the living area for two reasons, even, the second being its appropriate distance from the hazardous surface.
Earthquakes can't mess it up, but neither can an alien attack, because any offensive weapon, would need to pierce through several other stories of steel! Such a layer of protection was invaluable.
Alien technology may be capable of doing tremendous damage, but Tutan relied on basic science. A laser blast from a typical ship, for example, wouldn't be able to pierce through five meters of metal, not to mention anything greater.
