Space Exploration and Technology - Review

Question 1

Some satellites appear stationary to an Earth observer. This happens because:

Question 2

Normally, satellites orbit the Earth at a distance of

Answer 2

Hundreds of kilometers

Question 3

Which of the following satellites allows astronauts to live on board?

Answer 3

The ISS

Question 4

Space exploration has provided no technological or other spin-off benefits for us on Earth.

Answer 4

False

Question 5

One important function of all satellites is to:

Answer 5

Protect the payload from harmful aspects of the space environment

Question 6

We can get all the information we want about the universe from Earth’s surface with sending any satellites or probes into space.

Answer 6

False

Question 7

Humans can easily adapt to the conditions associated with long-term spaceflight

Answer 7

False

Question 8

This is a satellite image of what object?

Answer 8

The Sun

Question 9

Why are satellite images such as this useful to people on Earth?

Answer 9

Satellite images can tell us the size, direction and speed of strong storm systems like hurricanes

Question 10

What is the main use of a spectroscope in astronomy?

Answer 10

A spectroscope is used to measure and analyze different wavelengths of light coming from objects in the universe.

Question 11

When the lines in a star’s spectrum are shifted toward the red end of the spectrum, it means the star is:

Answer 11

Receding away from the observer

Question 12

A galaxy with a high degree of redshift in its spectrum is:

Answer 12

Very far away from the Milky Way

Question 13

Place the following facts in the appropriate column of the comparison chart. Columns are:
Robotic space probes (RSP); Human Beings (HB); Both (B)

Answer 13

• Is programmed in advance - RSP
• Uses both direct and indirect sensors - B
• Suited for work in harsh and hazardous conditions - RSP
• Needs regular rest and relaxation HB
• Readily learns and adapts to new information and conditions - HB
• Requires fuel and propulsion systems - B

Question 14

Which of the following is an advantage unique to human space explorers?

Answer 14

Ability to draw on broad knowledge base to solve unexpected problems

Question 15

Space exploration carried out by robotic space probes:

Answer 15

Has given us knowledge we could not have otherwise achieved

Question 16

Satellites move in the same pattern as the stars across the sky

Answer 16

False

Question 17

What satellite does the picture show?

Answer 17

The Hubble Space Telescope (HST)

Question 18

Human physiology evolved in the warm, moist, oxygen-rich and one-G environment of Earth, and we depend on this environment for survival

Answer 18

True

Question 19

What part of the electromagnetic spectrum do astronomers use to study the universe?

Answer 20

False

Question 21

What is a problem experienced by astronauts staying for long periods of time aboard the international space station?

Answer 21

Question 22

All of the following are hazards of living in space, EXCEPT…

Answer 22

Food consumption and exercise

Question 23

In the condition of weightlessness the body undergoes many changes. Because bones have less pressure on them in this type of gravity, they…

Answer 23

Question 24

Almost 100% of all materials used on the International Space Station are recycled. The primary reason for this is because of…

Answer 24

Storage Space
