Growing Food on Mars | MARS: How to Survive on Mars

[Music]
another thing that we’re going to need
when we go to Mars is food and so
probably that’s going to be growing some
of your own food and we want to do that
not by lugging everything worth but by
using what’s already on Mars so that
includes using the regular or the dirt
essentially now we know the soil at
least the topsoil on Mars can be very
toxic especially near the surface
everything is desiccated it’s just all
dried out
but underneath that we see the soil is
very different it’s got carbon hydrogen
nitrogen oxygen phosphorus so you’ll
probably be bringing that type of soil
into an area that you then can create
some sort of greenhouse we will start to
grow some food in hydroponic chambers
probably underground probably using LED
lights because we have to remember on
Mars can’t just go outside you know and
frozen seeds in the in the regula
they’re looking at taking microbes to
make meat it’s synthetic biology is what
it’s called but we’re learning how to
make vegetables having meat how to make
food to sustain the human body the most
efficient way to generate food to feed
people is with an algae farm if you have
a big pool of water you can grow algae
in it and certain strains of algae have
all the nutrients that humans need
eventually however you’re going to have
to terraform Mars itself so that you can
grow food on the surface of Mars
