Mars on Earth
Namib Desert: Namibia
The Namib is a coastal desert in southern Africa. The name Namib is of Nama
origin and means "vast place". According to the broadest definition,
the Namib stretches for more than 2,000 kilometres (1,200 mi) along the
Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa.
This is one of the most extreme environments on Earth, with very little
water and temperatures and unrelenting solar radiation that would kill
most animals.
But hidden under the rocks there is life – a thin green-blue layer of
cyanobacteria, a type of bacteria that converts the sun’s light into
energy.
“For life, there must be an organism at the base of the food chain, a
primary producer. In the deserts, we focused on photosynthesis … the
ability [of organisms] to produce biomass in the desert. Not importing
it, but producing it locally.”
On Mars, there is nowhere to “import” these base organisms from, so that
is why scientists are looking at how they survive on Earth in these
extreme environments.
Its large white water tower stands starkly against the red sand of the
dune seas behind it. It has the look of an outpost on a different
planet, and would be perfectly at home on the set of Star Wars.
