The Space Program

A spacecraft with instruments for collecting data, but no crew.

• space shuttle
• space probe
• Apollo 11
• microgravity

Spacecraft that is able to launch satellites, land like a plane, and be used again for a space launch.

• space probe
• Apollo 16
• Sputnik1
• space shuttle

The velocity needed to establish an orbit around a planetary body.

• escape velocity
• orbital velocity
• microgravity
• buzz lightyear

This is the reaction force that propels a rocket upward/forward.

• gases expelled
• microgravity
• thrust
• velocity

This is the name given to the rivalry between the U.S. and the Soviet Union to be the first to land a man on the moon.

• Space Jam
• Star Wars
• Space, the Final Frontier
• Space Race

These are the missions created for moon exploration.

• NASA

This is a robotic vehicle used for surface exploration of a moon or planet.

• rover

• jeep

Why was the International Space Station developed?

• A spacecraft used for landing on other planets.
• A long- term living space for use only by the U.S.
• For use as a long-term living space for carrying out experiments and observations.
• To study aliens.

This is condition that exists on the ISS due to it being farther away from the Earth's gravitational pull.

• super gravity
• zero gravity
• microgravity
• vacuum

The gases expelled by a rocket at launch are the 

• action force 
• reaction force
• negative force
• cool force
