4 dangers astronauts face during space missions
How canada contributes to space shuttle and working in space.
Canada arm 1
Robotic arm controlled by a remote. Used to launch and catch satellites
remote control Robotic arm that can access all parts of the ISS
International space station
Why is going to space and spending loads of money on space good?
We can learn more about our solar system.
we can know about our dangers around us.
Why is spending loads of money on space exploration bad?
- we could be using the money on Earth issues like poverty and ocean clean up.
- We can waste our money and time on something that may not work.
Purpose is to gather and focus the light from stars so that we can see them "light collectors"
A telescope that uses two lenses that bend light to gather and focus light from distant objects
A telescope that uses mirrors to collect and focus light from the stars. (Created by Issac Newton and can be made much larger)
Ability to distinguish details in an object
Technique of combining telescopes to improve resolution
Hubble Space Telescope
Reflecting telescope that orbits the earth in 95 minutes and was made to avoid weather issues, pollution, etc
forms of radiated energy that travel at the speed of light although they have different wavelengths and frequencies of light
Unmanned satellites used to explore areas or objects in space that are too difficult or dangerous to send humans to
Incoming signals are used to map out the composition and distribution of matter in space (Not affected by weather or pollution)
The apparent shift in position of a nearby object when the object is viewed from two different places
The study of spectra produced when a beam of light is passed through a prism
The apparent change in frequency of sound, light and other waves as the observer and the wave source move towards or away from each other
When a star approaches, wavelengths compress and get shorter. These spectra lines move to the ____
When a star moves farther away, wavelengths lengthen. These spectra lines move to the ____
Law of Physics
For every action, there is an equal and opposite reaction (proposed by Sir Issac Newton)
Structural/mechanical elements, fuel, payload
Basic parts of a rocket
Materials needed for flight
Engines that use xenon gas instead of chemical fuels
Uses the photons emitted from the sun to propel the sails (kind of like propelling boats using wind sails)
A method the allows the spacecraft to gain extra speed by using the gravity of a planet to slingshot around it
Transports panels and equipment to orbiting spacecraft
Contain instrumentation for carrying out robotic exploration of space, while communicating information back to earth
Orbiting spacecraft that have living quarters, work areas, and all the support systems needed to allow people to live and work in space for extended periods
International Space Station (ISS)
Consists of two or more stages. Each stage is separated and discarded once its fuel has been consumed. This reduces the weight of the rocket, increasing the speed
The condition in which gravitational forces that act on mass are greatly reduced
Benefits of Space Research
More environmental monitoring of earth, new understanding of earth, solar system and the universe, and medical and technological benefits
Costs of Space Research
Expensive, money could e spent on other stuff, possible weaponization of space, dangerous
A small body that orbits a large one
What type of satellite is a moon orbiting a planet?
What type of satellite is a spacecraft orbiting earth?
Weather satellites stay in one spot above earth and moves at the same rate as earth spins
A process in which imaging devices in a satellite make observations of earth's surface and send this information back to earth (senses weather, urbanization, resources)
GPS (Global Positioning System)
Radio signals from the satellites are picked up by the receiver and can show locations (24 in orbit)
The power of rockets to lift objects into space is described by a scientific law first developed by who?
When the sun reaches its highest or lowest point in the sky at noon
When the sun crosses the equator and day and night are of equal length
Unchanging patterns that form objects in the sky
The idea that the earth is the center of the universe and everything revolves around it
The idea that the sun is the center of the universe and everything revolves around it
Allowed scientists to get even closer to the night sky
Astronomical Unit (AU)
Used for measuring distances inside our solar system (equals 149, 599, 000km)
Light Year (LY)
Used for distances beyond the solar system, out to stars and galaxies
Hot, glowing ball of gas that gives off light energy
Shows the stars fall into several distinct groups comparing luminosity
A cloud in outer space consisting of gas or dust that forms after a star explodes (birth of a star)
A grouping of millions/billions of stars, gas and dust held together by gravity
Consists of a number of planets, moons, asteroids and comic dust orbiting stars
Theory on how solar systems are formed
Mercury, Venus, Earth, Mars
Inner planets (terrestrial) tend to be smaller, rocky and close to the sun
Jupiter, Saturn, Uranus, Neptune
Outer planets (jovian) tend to be large, gaseous and far from the sun
Balls of ice, rock, and dust that travel through space
Rocky metallic objects that orbit the sun but are too small to be considered planets
Small pieces of rock flying through space (in space)
When a meteoroid enters earths atmosphere, atmospheric friction causes it to light up (in atmosphere)
If the meteor lasts long enough to hit earth (once it hits the ground)
How far above the horizon something is (0-90 degrees). Zenith refers to the highest point directly overhead (90)
Determines which compass direction something can be found at in the sky (0-360 degrees)
