Balloon School
Today I toured MacTown and learned about the functions of all the
buildings. There is the water treatment plant (all the water comes
from the ocean). There is a fire station; this is a big deal here,
because it would be difficult to control a fire on an aircraft or a
burning building. There is a mail room where a lot of packages come
through. There are many dorm rooms, the helicopter pad, the science
buildings, machinery buildings and various smaller specialty
buildings. Everyone has a job doing some small thing in this outpost
of a town.
After freezing my toes on the tour we gather in the science lab to do
balloon school. My job is to become proficient with launching the
balloons with the other members of the group. The balloon is very
fragile and one small tear can ruin an expensive science experiment.
Helping us learn is Olivia and Becky, two science winter-over's. We
tour the launch site, check the helium tanks, and check the logistics
of a launch. Then we go over the sequence of the launch, my job is
to handle the helium intake and assist in keeping the balloon from
getting out of control.
Tomorrow there is a window of opportunity to launch an ozone balloon.
They are trying to sample a parcticular batch of air that was sampled
by another station in Antarctica and is circulating over the
continent in the Polar Vortex. If we launch tomorrow we can catch
that sample of air.
I saw beautiful Polar Stratospheric Clouds of all colors. These
refract and diffract sunlight from the frozen crystals they contain.
Later I observed the night sky and found the Magellenic clouds, these
are not clouds but look like smudges in the sky. Instead they are
two large galaxies circulating around the Milky Way.
