1. Space….
Test Review

2. When looking at the above picture, what could we determine based off this model?
If we went to the “Red” planet shown above, should we expect life to exist?
Why?
What features do we look for in order for life as we know it to exist?

3. What is microgravity?
Weightlessness, the floating sensation, common in space
How does this effect the large items we have stored away inside cargo holds? What must be done?
What effect does microgravity have on an astronaut’s bone health?
The stress on the bones decreases, resulting in bone deterioration
So what must be done in order to prevent this from happening?

4. Spacesuits are made with certain features in order to keep astronauts alive. List 3 features that spacesuits have and explain how these features keep astronauts alive.
1. Insulated layers to regulate temperature
Back pack provides O2 for inhaling and canisters to collect CO2
Stable internal pressure to force blood to certain parts of the body to counteract the absence of gravity
Storage Units for Waste Disposal

5. 1. Shields Earth from collisions
What are three (3) ways the atmosphere makes the existence of life on Earth possible?
1. Shields Earth from collisions
Offers protection from the Sun’s radiation
Allows for gas exchange between plants and animals
***DOES OUR TEMPERATURE CHANGE?***

6. List three (3) reasons that scientists use full scale mock-ups (training models) of space shuttles and the International Space Station before undertaking actual space missions-
to master all aspects of in-flight operating procedures
To familiarize crew members with emergency escape procedures
Guarantee safety, mission success, and save the expense of an actual mission

7. How can a model of the solar system be used in planning a trip from Earth to another planet?
to estimate distance, travel time, and fuel cost
To anticipate the frequency of meteorites
To map flights plans that avoid solar flares
Predict possible emergencies that astronauts might encounter

8. How can that same model be limited?
We cannot determine the size of the planets or Sun as we generally like to perform full-scale models.
We cannot determine the distance the planets will be unless we have a 3D representation of what it might look like.
***On the test, you will see the planets all in a straight line and no identifiable orbits. Is this how the solar system operates or is this also a limitation to how accurate the model will be?***
