Famous Rockets
Saturn V
force of gravity acting on an object’s mass that pulls the plane toward the ground.
Weight
Purposes of a satellite
communication (phone, TV, internet), navigation (GPS), and Earth observation (weather, climate, disaster monitoring).
Newton's law of motion that allows a rocket to lift off
Newton's third law (equal and opposite reaction)
Country that Sputnik 1 originated from
The Soviet Union
This rocket was European and was in service from 1996 to 2023.
Ariane V
The forward-pushing force created by engines or rockets.
Thrust
components/structure of a satellite
the bus, the payload, and the subsystems that include the power system, communication system, command and data handling, and attitude control and propulsion system
Kind of chemical reactions that occur inside a rocket
exothermic reduction-oxidation (redox) reactions, specifically combustion, to produce hot gases for thrust.
Miles per hour a rocket can exceed
165,000 mph
originated as an intercontinental ballistic missile (ICBM). launched the first American astronaut into orbit during the Mercury program
Atlas Rocket Series
force that pushes a plane upward, helping it rise into the sky. Air moving over and under the wings creates this upward push, letting the plane stay off the ground.
Lift
The balance that keeps satellites in orbit
balance between two forces: their forward momentum and the Earth's gravity
kinds of liquid propellants used in engines?
liquid hydrogen and liquid oxygen, which react to produce a large volume of hot gas (mostly water)
Most recent rocket campaign by NASA
Artemis
expendable launch vehicles that has been in use for over 60 years to launch spacecraft into orbit. Its legacy includes launching historic missions like the first communication satellite, and many scientific and military payloads.
Delta Rocket Series
force that slows the plane or rocket down, like air pushing against you when you run fast. To fly well, the engines must create enough thrust to overcome this air resistance.
first satellite in space
Sputnik 1
kinds of solid propellants used in engines
solid fuel (like powdered aluminum) with a solid oxidizer (like ammonium perchlorate) in a single mixture. When ignited, this mixture burns rapidly to produce gases like aluminum oxide, water, nitrogen, and hydrogen chloride.
Total number of people who have walked on the moon
12
space launch vehicles used to place satellites into orbit. boosted payloads into low earth orbit, polar orbit, or geosynchronous (stationary) orbit from either Cape Canaveral, Fla., or Vandenberg Air Force Base, Calif
Titan Rocket Series
having a shape which reduces the drag from air moving past
Aerodynamic
space-based observatory launched in 1990 that orbits Earth, providing the clearest views of the cosmos by avoiding atmospheric distortion.
Hubble Telescope
reason why rockets need propulsion
Rockets need propulsion to generate the force, called thrust, required to overcome gravity and accelerate
Fastest current fighter jet OR fastest retired fighter jet
NASA x-43 or SR-71 Blackbird
