könnte jemand mal einen Blick auf meinen Essay werfen? Für Verbesserungsvorschläge bin ich natürlich offen.
Jedenfalls geht es um folgendes Thema:
"What is your opinion on manned spaceflight, taking into account recent developments?"
There are several questions to think about when discussing about the need of manned spaceflight.
It is useful to begin by saying that manned spaceflight has become less important in comparison with
its beginnings, but I also think that it remains a vital element for future space missions. In my view the
strongest argument for the importance of manned spaceflight is the human thirst for adventure. We
have always aspire toward space, to be weightless and to explore foreign planets to get the knowledge
about developement of the universe. In addition, manned spaceflights provide the opportunity to study
the behaviour of materials and the human body under totally different conditions. And that for a longer
time as on parabolic flights. Furthermore, manned spaceflight paved the way for technologies like
satellites for our huge communication network and research facilities like the ISS or the
Hubble Space Telescope. And no one can say that it is boring to watch an astronaut levitate in space
or that images of distant galaxies have no scientific importance. Finally there is not yet a mature
alternative solution for a spaceman to make sure that the equipement works fine or rather to do
maintenance and repair.
However, there are also some points against manned spaceflight. The probably most valid argument
against such trips are the enormous costs. The astronauts need food, drinking and certainly oxygen.
This comes along with bigger place and security requirements and even more fuel. In addition to the
increased pollution by exhaust gases, there is another problem. Although the space shuttles are
reusable, the multistage rockets to get them into space remain there. This space debris surrounds
the earth and is dangerous for satellites and future spaceflights. The return of investment in comparison
with the costs of a manned space mission would be even bigger, if you send an unmanned vehicle on
space.
Weighing the pros and cons, I come to the conclusion that manned spaceflight still have a place in
space reasearch, although it has passed its zenith. With the proceeding deployment of robots and
their skills, our traditional imagination of spacemen will disappear step by step. These men and
women are not longer those who move weightlessness, but rather the ones who sit in front of a
monitor and control and survey the work of a robot.
