Women on top
THIRTY-FIVE YEARS after the Russian cosmonaut
Svetlana Savitskaya was the first
woman to take a spacewalk, a new historical
event took place above our heads on 18 October
2019. Two Nasa astronauts took the
first all-female spacewalk. It was not just for
fun, Christina Koch and Jessica Meir were
responsible for replacing defective equipment
from the International Space Station
(ISS), and in that way also formed the first
female maintenance team in the space.
Construction of the International Space
Station began in November 1998 and was
put into service two years later by the first
crew. Keeping this gigantic facility operational
is not easy (*). There were major
problems with an air leak in 2004, smoke development by the oxygen generator in
2006 and life-threatening computer problems in 2007 caused by condensation in
some electrical connectors. Some repairs require extra-vehicular activities (EVAs).
For example, in 2010 and 2013 there was a problem in an ammonia cooling circuit,
which required several space walks to replace a defective pump unit. So far, there
have been more than 1,000 hours and almost 200 space walks to perform modifications
and repairs on the outside of the station.
Congratulations from the Big Chief
Koch and Meir had to replace a defective battery charging and discharging unit
(BCDU) mounted on a truss on the outside of the ISS. BCDUs control the amount of
energy stored from the solar panels in the batteries. The defect was caused by a previous
replacement of a set of lithium-ion batteries. Because of the weightlessness
and absence of friction, working in space is not easy. The entire mission was meticulously
prepared and the general public could follow a lifestream of the astronauts,
dangling at 420 km above the earth’s surface, carrying out the repairs.
During the works, the NASA astronauts received a phone call from President
Donald Trump, who congratulated them on the historic spacewalk: “What you do is
incredible”. As far as I’m concerned, a lot of CEOs could take Trump as an example
and give their maintenance workers more often a pat on the back for their valuable
work.
Feminize the technical world
After the mission there was a lot of praise for the historical spacewalk. However,
there was also criticism because it took more than 44 years after the first space walk
before two women could go on a spacewalk together. This apparently had to do with
the fact that the space suits were made to measure for a man’s body. During an interview
before the space walk, Christina Koch put her finger on the wound: “In the
past, women have not always sat at the table...”.
We urgently need to get rid of the stereotypical image that only men are suitable
for technical work. Let’s all work on this consciously. For example, by actively looking
for female technical talent. However, this will not be enough to get more female
maintenance technicians and engineers on the shop floor. After all, the image of
typical female or male professions starts at a young age. Specialists point out that it
is important to consciously avoid stereotypes from childhood onwards. And you can
do something about that too. Maybe YOU can start in the upcoming holiday season
by asking Santa Claus to bring your (grand)daughter a cool set of tools and matching
tool belt? A valuable present that could launch her future career to the top...
