inertia
the tendency of an object at rest to stay at rest and an object in motion to stay in motion
spaceship 1
aircraft with suborbital capacity
spaceship 2

salyut
russia’s first space station
spacelab
european space agency’s first space station
bernoulli’s principle
when a fluid’s velocity is flowing at low velocity, pressure is high, when air flows through a restriction, the velocity accelerates and the pressure drops.
downwash
force pressing down hard on surrounding air pushing the wing up
vertical axis (YAW)
moves the tail/nose left or right
longitudinal axis
rolls the aircraft left or right
lateral axis PITCH
moves nose up and down
MQ9

average rate at which temperature decreases with an increase in altitude
combustion chamber
enclosed container in which air and fuel are burned for the production of energy
engine aka the powerplant
uses energy to run other accessories
photosphere
the part of the sun that gives off light
vane
tilted to control the direction of a rocket
sailplane
uses energy from the environment and any method possible to find lift and ride it to a greater height
