1
How does the spacesuit backpack help astronauts breathe in a space environment?
Provides pure O2 for inhaling and canisters to collect CO2
Maintains air pressure to keep bodily fluids from boiling
Collects urine and solid wastes
Stabilizes an internal temperature of 22° C (72° F)
2
Using the picture, why does the Moon most likely
NOT
support life?
Too much sulfur, indicating all organisms can't make energy
It is too far from the Sun
Many craters, shows it doesn't have a protective atmosphere
It has too much volcanic activity
3
Which of the following would be the
BEST
planet to observe for life?
A
D
C
B
4
Which characteristic of the planet Earth is essential to the survival of every living organism?
Earth orbits the Sun once every 365 days
Earth rotates on its axis once every 24 hrs
Earth has abundant water
Earth has just one orbiting moon
5
How can a model of the solar system be used in planning a trip from Earth to another planet?
To map flight plans to avoid solar winds
To predict possible emergencies astronauts may encounter
To anticipate the frequency of meteorites
To estimate distance, travel time, and fuel cost
6
If there were increased holes in the ozone, it is reasonable to predict that organisms would -
experience colder temperatures
have a difficult time breathing
be more exposed to ultraviolet radiation
run out of drinking water
7
Equipment inside a space vehicle must be attached by velcro to accommodate for which factor?
Increased gravity
Microgravity
Gravity
Zero gravity
8
One disadvantage of exploring Europa (one of Jupiter’s moons) for life is that it is -
probably capable of supporting only microscopic life
far from the Sun and likely has extreme temperatures
very large, making it hard to travel on
very similar to Earth’s moon, which is known not have life
9
The insulated feature of spacesuit layers are designed to —
Provide pure O2
Trap excessive CO2
Regulate temperature
Protect from radiation
10
Which accommodation is designed to overcome the difficulties associated w showering in space?
A vacuum system to control water movement
A drain in the floor of the shower
A skid-proof floor mat
A bench inside the shower
11
Which of the following is
NOT
an accommodation provided by the astronaut's suit?
Insulation
Waste management
Air pressure
Microgravity
12
Which of the following make it possible for water to exist in all 3 states on Earth?
the presence of Earth’s moon and the moon’s orbit
the magnitude of Earth’s radius and mass
the presence of plants and animals on Earth’s surface
the spinning of Earth’s rotation & its distance from the Sun
13
How does an astronaut on a spacewalk communicate with astronauts in the spacecraft?
using sign language
by cellular telephone
through a radio transmitter & receiver
through radio waves from Earth
14
Why is the Sun necessary for animals to live on Earth?
Animals require water & plants convert energy into water
Energy from the sun reaches Earth by photosynthesis
Animals convert the sun’s radiant energy into food
Plants convert the Sun’s radiant energy into food
15
What accommodation for space flight is most obvious on the outside of this space station?
Solar cells to produce electricity
Rocket motors for reentry and landing on Earth
A gymnasium for the astronauts to exercise
A fire suppression system in case the exterior catches fire
16
Which accommodation will most likely protect the muscle health of the crew on a space mission?
Wearing protective clothing while inside the space vehicle
Engaging in a daily routine using exercise equipment
Eating more calories
Drinking extra fluids
17
As the planet’s distance from the Sun increases, the surface temperature of the planet -
Decreases
Increases then decreases
Stays the same
Increases
18
Which of the following spacecraft is designed to collect data by landing on distant planets?
Satellite
ISS
Space Shuttle
Rover
19
What is the purpose of a rocket during the launch of a spacecraft?
to prevent the spacecraft from moving faster
to provide enough power to overcome Earth’s gravity
to give extra thrust to help steer the spacecraft into orbit
balance the spacecraft as it moves out of Earth’s atmosphere
20
Which of the following is
NOT
a limitation of the model?
Size of the planets
Number of planets
Distances between planets
Size of the Sun
21
Why would planet E
NOT
be a good place to look for life?
No Oxygen
Too cold
No water
Too hot
22
What is the most important factor that determines Earth’s temperature?
Gas composition of the atmosphere
Distance to the Moon
Proximity to the Sun
Amount of water on the planet
