PSA Systems:
The PSA is a complicated system made of parts that allow it to
communicate, navigate around various spacecraft, detect heat
or gas levels, "see" its
environment and hold a lot of data. What are the parts that make
up the PSA and what are they used for? Find out in this section
with a clickable PSA!
Forces and Motion:
Things in space
move quite differently than they do on Earth. These forces and
motion activities will give you a feel for how the PSA moves in
microgravity. Watch this [low or high bandwidth]
to learn what the PSA will have to do in space before you begin
the activities.
Now that you've worked with the PSA a little bit, you should begin
to notice certain rules for its movement. The following activities
will ask you to make various predictions. See if you can figure
out how the PSA moves, then test your predictions.
 |
How long does it take the
PSA to stop on its own? |
| |
|
 |
How does a PSA with more mass
move differently than a PSA with less mass? |
| |
|
 |
How many thrusts will you
need to apply to stop the PSA in one dimension? |
| |
|
 |
In what direction must you
apply thrust to stop the PSA? |
| |
|
 |
How many thrusts will you
need to apply to stop the PSA in two dimensions? |
| |
|
 |
What is the minimum number
of thrusts to stop the PSA in one dimension? |
| |
|
 |
What is the minimum number
of thrusts to stop the PSA in two dimensions? |
