Gravity and thrust
Thrust and torque
Drag and gravity
In this illustration of a liquid-fuel rocket, which letter represents the payload?
A
B
C
D
What is one main difference between solid-fuel rockets and liquid-fuel rockets?
Solid-fuel rockets don't require an oxidizer to work; liquid-fuel rockets do
Liquid-fuel rockets can't lift heavy payloads; solid-fuel rockets can
Solid fuel-rockets launch with pre-mixed fuel and oxidizer; liquid-fuel rockets combine the fuel and oxidizer at launch
Liquid-fuel rockets contain a higher proportion of oxidizer to fuel than solid-fuel rockets do
can work in a number of areas, but they generally analyze, design, develop, and test aircraft, spacecraft, or missile systems. They work with airplane systems, while astronautic engineers focus on spacecraft.

Plan a NASA scientific mission to Mars. Consider the objectives, the equipment needed, the potential challenges, and the benefits of the mission.
Send a robot to collect soil samples, study potential for life, face challenges like dust storms, benefit by understanding if humans can live on Mars.
Send a telescope to Mars to observe Earth from a distance, face challenges like light pollution, benefit by getting clearer images of space.
Send a manned mission to explore the deep seas of Mars, face challenges like underwater navigation, benefit by discovering new marine species.
Send a satellite to orbit Mars to play music, face challenges like signal transmission, benefit by entertaining astronauts on Mars.
Which spacecraft was the first to leave the Solar System?
Voyager 1
Voyager 2
Pioneer 10
New Horizons
Which mission first successfully landed humans on the Moon?
Apollo 11
Voyager 1
Mars Rover Perseverance
Galileo
When you throw an object straight up, why doesn't it fly off into space?
There's too much thrust acting on the object
Earth's atmosphere prevents the object from going into space
The object travels too fast to reach Earth orbit
The force of gravity pulls the object back down to Earth
A jet pack is a type of rocket system that can allow a human to "fly" for short distances. What can you infer about how jet packs work?
The thrust created by a jet pack must be greater than the force of gravity acting on the user and the pack.
The user must weigh less than the jet pack to lift off the ground.
The weight of the fuel in the jet pack must be greater than the weight of the user in order to achieve liftoff.
The force of gravity on the user must decrease as he is lifted off the ground.
Put the following into the correct order for a rocket launch: Heated gas is expelled; Oxidizer and fuel mix; Force of thrust exceeds force of gravity on the rocket.

Which part(s) of the U.S. space shuttle is/are not reusable?
The orbiter
The external fuel tank
The solid rocket boosters
The main engine nozzles
After earning a Ph.D. in physics, _______________ patented two devices in 1914: a rocket powered by liquid gasoline and nitrous oxide, and a multi-stage, solid-fuel rocket. Five years later, he published a groundbreaking work entitled, A Method of Reaching Extreme Altitudes, in which he discussed the possibility of launching a rocket that could escape Earth’s gravity and reach the moon.

There are ________________ spacecraft now on their way out of the solar system. The farthest from the sun is Voyager 1, which launched in 1977 and is already more than 100 AU away from home. (1 AU, or astronomical unit, equals about 150 million kilometers.) That sounds far, but consider this: The closest star to the sun, Proxima Centauri, is 267,000 AU away!

The farther apart two objects are, the weaker the force of gravity is between them. What can you infer from this?
A body orbiting Saturn feels a weaker gravitational pull from Earth than a body orbiting Mars
The Earth's gravity exerts a stronger pull on spacecraft orbiting the moon than spacecraft in low-earth orbit
A spacecraft that has left the solar system feels no gravitational pull whatsoever from Earth
Any spacecraft launched from Earth will, given enough time, eventually fall into the sun
