Mars One Is Still Completely Unrealistic
J Thoendell stashed this in Space
There are basically two types of technology we need for humans to live on Mars. (Assuming we have the rockets and spacecraft.) First, there’s life support: The stuff inside the Martian habitats that’ll recycle our air, water and nutrients, ensuring gases like CO2 and oxygen remain in balance. Then there’s what the engineers call in situ resource utilisation (ISRU) tech. This is the technology we’ll need to extract resources from Mars. For Mars One to work, we need to extract water from the Martian soil to drink, and nitrogen and oxygen from the air to build an atmosphere. All of this technology, Lansdorp says, already exists.
Does it, though?
If you squint a bit, the answer could be yes. When it comes to life support, Mars One often compares its proposed systems to those aboard the International Space Station. Fair enough. Life support systems on the ISS are already proven to work pretty well in a space environment and under microgravity conditions. So there’s no reason, in theory, that these systems won’t work on Mars.
But as Owens pointed out last night, life support systems on the ISS are repaired and replaced pretty regularly, by taking advantage of the vast horde of spare parts located some 249 miles below the station.
“One of the things we’ve learned from the ISS is that these systems need repair,” Owens said. “The ISS goes about 3 months between resupplies. When something goes wrong, you come home.”
Yeah, I'm squinting and the answer for me is still no.
There's a big difference being just 249 miles away because, as the article puts it, you can go home easily.
