- Who is Werner Von Braun?
- Designed German U2 rocket, which destroyed both military and civilian targets. He came to the US after WWII and developed many rockets used in the US space program.
- remote sensing
- the collection of information about Earth and other objects in space without being in direct contact
- space station
- is a large artificial satellite on which people cna live and work for long periods - long term observations and experiments can be carried out in space
- Yuri Gagarin
- the first human launched in to space - by the Soviets in 1961 - he flew one orbit around the Earth
- escape velocity
- the velocity a rocket must reach to fly beyond a planet's gravitational pull
- space spinoff
- an item that has uses on Earthbut was originally developed for use in space
- satellite
- is an object that revolves around another object in space
- space shuttle
- is a spacecraft that can carry a crew into space, return to Earth and then be reused for the same purpose
- space probe
- is a spacecraft that carries scientific instruments that can collect data, but has no human crew
- Neil Armstrong & Buzz Aldrin
- landed in a tiny spacecraft called Eagle on the moon on July 20, 1969
- NASA
- National Aeronautic and Space Administration - a US government agency in charge of the space program
- John Glenn
- first American to orbit the Earth (3 times) in 1962 aboard Friendship 7
- What is the space race?
- Began in 1957 when the Soviets launched the satellite Sputnik I into orbit. The US responded by speeding up its own space program.
- What did the first rocket look like?
- They were arrows covered with a flammable powder that were lit and shot with bows.
- moonquakes
- caused when Apollo astronauts purposely crashed equipment on the moon's surface
- multistage rocket
- smaller rockets or stages are placed one on top of the other and then fired in succession
- How do rockets work?
- Smaller rockets, or stages are placed on top of each other and fired in succession.
- Alan Shepard
- first American in space in spacecraft called Freedom 7
- Who made improvements on the first rocket?
- The British improved rocketry in the early 1800's.
- orbital velocity
- is the velocity a rocket must achieve to establish an orbit around Earth
- microgravity
- a feeling of weightlessness
- Who made the first rocket?
- The Chinese
- Apollo Program
- the American effort to land a man on the moon
- What are the 3 types of fuel used to power modern spacecraft?
- 1) solid fuel 2) liquid fuel 3) electrically charged particles of gas (ions)
- sputnik I
- a satellite launched into orbit by the Soviets in 1957. It started the space race.
- vaccum
- a place that is empty of all matter
- geosynchronous orbit
- when a satellite orbits Earth at the same rate as Earth rotates and so stays over the same place on Earth all the time
- rovers
- small robots that have instruments to collect and analyze soil and rock samples - they can move aruond on the surface of a planet and are part of a space probe
- thrust
- the reaction force that propels a rocket forward
- rocket
- a device that releases gas in one direction and moves in the opposite direction
- velocity
- the speed in a given direction
