Participation in the following discussion will result in up to 10 points being added
to your final point total for the class.
For this discussion forum, first watch the following videos,
Minutes to watch:
0 to 6:10
Minutes to watch:
0 to 8:33
and give your preference on which planet we should focus our resources for possibly
establishing presence on. Use the information addressed in the videos to support your
argument for the planet you favor. Feel free to provide an argument for why we should not
bother colonizing either planet, if that's what you prefer. Regardless of your choice, discuss
whether you think humans need to become interplanetary (later on, possibly interstellar)
species. Refer to Chapter 10 of our OpenStax Astronomy Textbook for additional information
on Venus and Mars.
In addition, watch the following video,
"New Martian Settlements Coming Soon"

and as an exercise in colonizing other worlds, outline a plan for establishing a sustainable
settlement on Mars. You can assume the issue of getting to Mars has been solved. This is not
supposed to be a foolproof plan that you have to submit to NASA, but rather a fun exercise
in planning a hypothetical relocation to Mars. Consider what humans need to survive, such
as air, water, protection from radiation, food. What do you need to bring from Earth and
what can you obtain on Mars? Think about best location and choice of shelter. Think about
what you will use for energy and how you can best use what Mars has to offer naturally for a
successful colonization.

A few important things:
You are expected to be respectful of persons in the discussion. You certainly don't
have to agree with others, but things like name calling are unacceptable and will
result in a loss of points.
Your posts and comments should be of reasonable length and thought to count
for credit.
You should comment on at least TWO classmates' posts.
Short
answers like "Well said" or "I agree", etc., won't count for points. You need to
show substance, depth of thought, and contribution for the points.
Spelling and grammar aren't explicitly counted. However, if your
spelling/grammar is so bad as to distract from your point, you may lose some
credit.
You won't be able to see the posts of others until you make your first post with
your answer.
The idea of settling on other planets has been suggested to ensure the
survival of humans in case Earth becomes uninhabitable. Mars and Venus
have been considered as potential options for colonization. Mars is seen as
the more practical option because it is closer to Earth, has a mild climate,
and contains water ice. However, Mars has a thin atmosphere, making it
difficult to protect against radiation and other hazards. In contrast, Venus has
a thick atmosphere that offers protection against such threats. However, the
surface of Venus is incredibly hot, with temperatures that can melt lead, and
the atmospheric pressure is immense. Despite their differences, Venus is
very similar to Earth compared to other planets in our solar system. It is
called Earth's "sister planet" because it has 90% of Earth's gravity and is
about the same size. This makes Venus a desirable location for future
colonization. But, how can we survive in an atmosphere full of carbon
dioxide, no water, and extreme heat? Living on the surface of Venus is
impossible. Instead, a hypothetical Venusian colony would be suspended by
blimps floating 31 miles above the surface. Although there are plenty of
challenges associated with living above the surface of Venus, it would still be
easier than setting up a colony on the surface of Mars. In conclusion, both
planets have their advantages and disadvantages when it comes to
colonization, with Mars being the more feasible option and Venus offering a
thick atmosphere. The decision to colonize either planet will depend on
various factors, including resource availability, technological challenges, and
ethical considerations.
