Who developed the theory of rocket propulsion?

• Robert Goddard

• Isaac Newton

• Johannes Kepler

• Konstantin Tsiolkovsky

What is the purpose of a space probe?

• to transfer supplies to a space station

• to carry astronauts to new planets

• to gather data

• to stabilize the atmosphere of a planet

Satellites that need to maintain a constant location travel in which orbit?

• escape

• polar

• geosynchronous

• low Earth

What force is the result of gravity, velocity, and inertia working together?

Why was the space shuttle program started?

• to save money

• to prepare for Mars exporation

• to win the Space Race

• to land a man on the moon

If the Pioneer 10 space probe is no longer in service, why do scientists believe it is

going to travel in a straight line to reach Aldebaran?

• The data it sent to Earth showed a

  course change.

• The gravity on Aldebaran is pulling it.

• Its own inertia is propelling it.

• It was programmed to travel that

  distance.
