Telescopes
Refracting telescopes use these to gather light.
lenses
This telescope measures visible light.
optical telescope
Unmanned spacecraft sent to other planets are called these.
probes
This astronaut was the first Canadian in space.
Marc Garneau
The apparent shift of an object when viewed from two locations is called this.
parallax
This type of propulsion system uses sunlight for movement.
solar sail
Reflecting telescopes use these to gather light.
mirrors
This type of telescope can be used day and night.
radio telescope
Satellites that determine exact positions on Earth are part of this system.
GPS
Canada became this numbered nation to launch a satellite into space.
third
Astronomers use this instrument to determine the elements in stars.
spectrometer
This propulsion system uses far less fuel than chemical rockets.
ion drive
Most refracting telescopes contain this number of lenses.
2
Groups of radio telescopes are called these.
arrays
A satellite that stays above the same spot on Earth is in this type of orbit.
geosynchronous orbit
Canada’s first satellite was called this.
Alouette 1
In triangulation, this is the reference line between two observation points.
baseline
Ownership of space resources is this type of issue, political or environmental?
political
Combining several telescopes together is called this.
interferometry
The Hubble Space Telescope is this type of telescope.
reflecting telescope
This waste product aboard the ISS is NOT recycled.
carbon dioxide
Canadarm 2 can do this better than the original Canadarm.
move around outside the ISS
Electromagnetic radiation includes these very high-energy rays.
gamma rays
Cleaning up space junk is this type of issue, political or environmental?
environmental
Telescopes are often built at high elevations to reduce this.
atmospheric interference
Space telescopes have an advantage because they are not affected by this.
earth's atmosphere
If a spacecraft re-enters Earth’s atmosphere at too shallow an angle, this may happen
bounce off the atmosphere
Canada contributed this to Apollo 11
landing gear
Electromagnetic radiation travels in this type of pattern.
wave pattern
Space food technology helped create these foods on Earth.
