any man-made object placed in orbit around a body in space
artificial satellite
the speed and direction a rocket must travel in order to completely break away from a planet’s gravitational pull
escape velocity
an orbit in which a satellite travels at a speed that matches the rotational speed of the Earth
geosynchronous orbit
an orbit located a few hundred kilometers above Earth’s surface
low Earth orbit
National Aeronautics and Space Administration
NASA
the speed and direction a rocket must have in order to orbit the Earth
orbital velocity
a machine that uses escaping gas to move
rocket
a vehicle that carries scientific instruments to planets or other bodies in space
space probe
a reusable vehicle that takes off like a rocket and lands like an airplane
space shuttle
a long-term orbiting platform from which other vehicles can be launched or scientific research can be done
space station
the force that accelerates a rocket
thrust
explained how rockets worked. He was inspired by Jules Verne and he thought that rockets were the key to exploring space.
Tsiokovsky
father of modern rocketry. He tested more than 150 rockets and received attention from the US military
Robert Goddard
developed the V-2 rocket _________ and his scientists surrendered to the Americans in WWII and rocket research boomed in the 1950s.
Von Braun
it was formed in response to the alarm of Soviet superiority. This led to the development of a series of rockets, especially the Saturn V which is the biggest rocket.

what works on Newton’s 3rd law of motion
rockets
For every action, there is an equal and opposite reaction in the opposite direction. (action: reaction pairs)
Newton’s 3rd law of motion
who was the 1st to use rocket fuel.
Robert Goddard
Rockets in order to orbit the Earth must reach__________
orbital velocity
Russia sent the 1st satellite into space called Sputnik I; this started the Space Race between the US and Russia
October 4, 1957
when did the US launched their 1st satellite, Explorer I. This satellite discovered the Van Allen radiation belts found in our atmosphere.
January 31, 1958
used for radio, TV, and cell phone transmission
Communications satellites
what type of orbit is located a few hundred kilometers above Earth’s surface
Low Earth orbit (LEO)
travels at the same rate as Earth’s rotational speed focuses on the same location on Earth best used for weather and communications satellites
Geosynchronous orbit (GEO)
Yuri Gargarin, a Soviet cosmonaut, became the 1st human to orbit the Earth
April 12. 1961
