The challanges of space 7
• Extreme temperatures • No air / vacuum • Low gravity (microgravity) • Radiation • Space debris and micrometeoroids • Isolation and psychological effects • High cost and limited resources
the risks of space 6
• Radiation exposure • Effects of low gravity (microgravity) • Space debris and micrometeoroids • Loss of air or pressure failure • Equipment or system failure • Psychological risks
what is the altitude-azimuth coordinate system
The altitude–azimuth system locates objects in the sky using two angles: altitude (height above the horizon) and azimuth (direction along the horizon).
geocentric solar system models
earth centred
heliocentric solar system models
sun centred
describe how spectroscopes allow humans to determine the composition of stars
Spectroscopes determine what stars are made of by splitting starlight into a spectrum and identifying unique dark-line patterns that match specific elements.
interferometry
A technique that combines signals from 2 or more telescopes to make one clearer, more detailed image
red shifted stars
An object is moving away from you, and its light stretches longer
blue shifted stars
An object is moving toward you, and its light shifts shorter
how are red and blue shifted stars related to the doppler effect
Redshift and blueshift happen because of the Doppler effect: light from objects moving away is stretched (redshift), and light from objects moving toward us is compressed (blueshift).
geosynchronus
A geosynchronous orbit is when a satellite orbits Earth in exactly the same time it takes Earth to rotate once. It is also 22+ thousand miles above earth
low earth orbit
A Low Earth Orbit (LEO) is a type of orbit where satellites move very close to Earth.
what are satellites used for 5
Satellites are used for communication, weather forecasting, navigation, Earth observation, and scientific research.
benifits and advantages of the hubble space telescope over any other type of telescope
It’s location above Earth’s distorting atmosphere, allowing it to capture clear, higher resolution images in ultraviolet, visible, and infrared light than ground-based telescopes
benifits and advantages of a radio telescope over any other type of telescope 4
Radio telescopes can observe space in all weather, see through dust clouds, detect invisible radio-wave sources, and be combined for very high resolution.
explain the process of triangulation
Triangulation is a method used to find the position or distance of an object by measuring angles from two known points that are a fixed distance apart (called a baseline).
explain the process of parallax
Parallax measures distance by observing how an object appears to move when viewed from two different positions, then using the angle of shift to calculate how far away it is.
names of all planets 8
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune
names of the astroid belts
It is also sometimes called the Main Asteroid Belt or just the Main Belt.
relative location of all planets
sun-Mercury → Venus → Earth → Mars → Jupiter → Saturn → Uranus → Neptune
relative location of the astroid belts
sits between mars and jupiter
doppler effect
When the sound or light waves change because the source is moving
