Vocabulary
Space
Science
Gyroscope - A spinning
wheel that tends to maintain its direction in space.
Momentum - The
tendency of a moving object to keep moving.
Moon - A natural object
orbiting a planet.
Orbit - The path of a satellite around a planet or of
a planet around its star.
Planet - A large, natural object that orbits a
star.
Revolve - To move in a
circular orbit; such as the Earth going around the sun.
Rotate - To turn around
an axis or center point; which causes day and night on the Earth.
Satellite - A natural or
man-made object which orbits a larger object; such as the moon orbiting the
Earth.
Solar system - A system of a
stars and all the objects that orbit it; Our solar system includes the sun, 9
planets, their moons, asteroids, and comets.
Space - The area above a planet’s
atmosphere.
Space probe - An unmanned
spacecraft that explores the solar system and sends data back to Earth.
Stability - Resistance of
an object to a change in its position.
Star - A point of light in the night
sky. In the daytime only one star is visible - the sun - which, like the other
stars, is a ball of gas which produces its own heat and light.
Trajectory -The curve of
the path of a spacecraft in flight.
Vacuum - A space containing no
matter or air.
Velocity - The speed and direction of an object.
Aeronautics
Ailerons -The parts of
the wing that control the airplane’s roll (its left and right tilting).
Air pressure - The force of air
spread over a surface; it can be caused by the weight of the atmosphere above
or by moving through the atmosphere.
Airfoil - The shape of a
wing’s cross-section (a slice across the wing), designed to create as much lift
and as little drag as possible.
Atmosphere - The gases
surrounding a planet.
Drag - The force due to air that slows
down the plane as it moves forward.
Elevator - The part on
the tail that controls the plane’s pitch (its up and down tilting).
Force - A push or pull on an object.
Fuselage - The part of a
plane which holds people and cargo and to which the wings and tail are
attached.
Gravity - The force of
attraction between two objects (such as the force between you and the Earth).
Lift - The force that keeps an
airplane up due to the flow of air over and under the wings.
Mach - A number that compares an
airplane’s speed to the speed of sound 750 mph. (At Mach 2, a plane goes twice
the speed of sound).
Rudder - The parts of
the tail surfaces that control a plane’s yaw (its left and right turning).
Supersonic - A term that
indicates motion faster than the speed of sound (more than Mach 1 but less than
Mach 5).
Thrust - The force of
the engine, which pushes a plane forward.
Wind tunnel - A long tube or
tunnel in which an airplane is held still and air is blown over it. They are
used to test airplane designs by simulating flight while instruments measure
lift and drag.
Space
Station
Astronaut - A person who
trains to fly into space.
Cosmonaut - A Russian
astronaut.
Dehydrate - To dry out.
Engineer - A person
trained to design, construct, and operate mechanical or electrical instruments.
Environment - The air,
water, minerals, organisms and all other interconnected things in a particular
place.
Freefall - A condition
where an object is falling without being stopped or slowed down, if its
surroundings are also falling at the same rate, the object appears to float.
This occurs on a spacecraft in orbit.
Observation - The act of
gathering information by watching or by remote sensing.
Payload - All the cargo,
including scientific equipment, carried in a spacecraft.
Pressurize - To raise the
atmospheric pressure to the desired level in a closed area, such as a space
suit.
Pulse - A heartbeat.
Ration - A fixed amount
of food or water when the supply is limited.
Recycle - To treat
material so that it can be used again.
Solar panel - A device that
changes sunlight into electricity; made of solar cells.
Space shuttle - A reusable,
crewed spacecraft used to place satellites in earth orbit and to conduct
experiments.
Space station - A manned structure that orbits the Earth
and is used for a variety of purposes, especially research.
Weightless -
Being without weight, as an object in freefall or orbit.
Mission
Control
Altitude - The height
above sea level.
Communications - A means of
sending and receiving messages and information.
Debriefing - The discussion
of the results of a mission.
Geology - The study of
the earth, including rocks and minerals.
Infrared - A type of
light that can’t be seen by humans but that instruments can use to measure the
heat differences between objects.
Latitude - The distance
north and south from the Equator, expressed in degrees.
Longitude - The distance
east and west from Greenwich, England, expressed in degrees.
Lunar - A term referring to the moon.
Mission - A particular
task that a person or group is to perform.
Remote - Far away.
Scientist - An expert in
science.
Sensing - Seeing,
feeling, tasting, smelling or hearing;The ways people, animals, and instruments
perceive the things around them.
Specialist - A person who concentrates on one subject or area
of interest.
Volcanic - A term meaning formed by a volcano.
