>It is fully backed by NASA science and experiments. You'd know that if you could see, but your VIIPs has already fucked you over, brittle bones.

NASA says bone loss in zero-g is basically solved by exercise. Also, there were NO experiments done on procreation and development of mammals in zero or partial gravity. We just do not know.

>Typically, astronauts would return to Earth with a total of 4 percent to 5 percent of their body mass gone.
>“Now, it’s a rule to have it more or less unchanged,” Barratt said. “We’re seeing insignificant changes in bone density. We’re actually seeing an increase in lean body mass and decrease in body fat.

To understand why they are doing this in a seemingly low-tech way like this, you have to keep in mind that this is a fucking Mars rocket. There are no launch facilities on Mars. This will not be your usual delicate launch vehicle.

This entire thing will be launched by a crew of a dozen men working over a few days. There will be no launch pad, it will be done from an uneven ground, with dirt in the nozzle and dirt in the fuel tank. Mueller is known for feeding nuts into Merlin intake, what do you think he will do to Raptors?

Then after it is launched to 5 km, it will land on dirt, again be refueled by the same handful of people over one day, and launch again. And then again.

Mars demands nothing less.
