- NASA
- National Aeronautics and Space Administration
- NASA
- They explore, discover, and seek to understand.
- Newton's Laws of Motion
- Rockets move to this
- Newton's Laws of Motion
- for every action, there's an equal but opposite reaction
- Newton's Laws of Motion
- Ex: gases push down through the nozzle while the rocket is pushed up
- Force
- exhaust gases are under extreme pressure in there combustion chambers
- Force
- exerts a huge amounts of this called thrust
- Force
- trust is needed to overcome gravity
- Gravity
- pulling force between 2 objects w/ mass
- Gravity
- pulls stuff to its core
- Gravity
- speed and direction needed for objects to completely break away from Earth's gravitational pull
- Gravity
- speed and direction needed for objects to orbit Earth
- Inertia
- Newton's 1st Law
- Inertia
- an object in motion must stay in motion unless acted upon by another force
- inertia
- forward motion
- friction
- the rubbing of 2 objects w/ in our atmosphere
- friction
- objects in our atmosphere experience this with air molecules
- friction
- will slow or possibly burn up objects in motion through our atmosphere
- artificial satellite
- man-made object placed in orbit around a body in space
- artificial satellite
- 2 placements for these: LEO & GEO
- orbit
- to revolve around a body of space
- orbit
- over 1000 artificial satellites do this
- LEO
- in outermost layers of our atmosphere
- LEO
- move fast
- LEO
- 1 time around = 90 minutes
- GEO
- slow moving
- GEO
- beyond our atmosphere but still in Earth's gravitational pull
- GEO
- keeps pace with Earth's spin & does't seem to move
- space probe
- carries scientific instruments to planets or other bodies in space with no crew
- space probe
- requires escape velocity to pull away from Earth's pull
- space shuttle
- reusable space craft
- space shuttle
- takes off like a rocket and lands like an airplane
- space shuttle
- has 4 parts: huge fuel tank, rocket boosters, and orbiter
- space shuttle
- Ex: Atlantis Discovery Endeavor remain in use and are scheduled to retire in 2010
- space station
- an orbiting platform in space
- space station
- was built by the US, Russia, and other countries
- space station
- Astronauts live there for months and do experiments and research there
- spinoffs
- technology and materials originally built for space program
- spinoffs
- Ex: joysticks, tang orange drink, cordless tools, lasers, memory foam, etc.
- spinoffs
- lots of $ is made by companies that develop these
- telescope
- collects various forms of light and concentrates it for better observation
- electromagnetic spectrum
- all wave lengths of light radiation given off by objects
- electromagnetic spectrum
- form of light depends on wave length
- optical telescopes
- for viewing visible light
- reflecting telescopes
- telescopes using a curved mirror
- refracting telescopes
- telescopes using curved lenses to gather and focus
- Non-optical telescopes
- collects invisible waves
- radio telescope
- collects radio waves
- infrared telescope
- collects infrared waves (heat waves)
- x-ray telescope
- collects x-ray waves
- gamma telescope
- collects gamma waves (bomb waves)
- Ultraviolet Telescope
- collects UV waves (light waves)
