Why are solar-powered satellites preferred over traditional satellites?
-
They are more cost-effective
-
They are environmentally friendly
-
They have longer operational lifetimes
-
All of the above
Correct Answer
A. All of the aboveExplanation
Solar-powered satellites are more cost-effective, environmentally friendly, and can have longer operational lifetimes compared to traditional satellites relying on alternative power sources.Rate this question:
-
- 4.
What happens to excess solar energy generated by the satellite?
-
It is wasted
-
It is stored in onboard batteries
-
It is transmitted back to Earth
-
It is converted into heat and radiated into space
Correct Answer
A. It is stored in onboard batteriesExplanation
Excess solar energy generated by the satellite is stored in onboard batteries for periods when sunlight is not available, ensuring continuous power supply.Rate this question:
-
- 5.
Which region of the electromagnetic spectrum provides solar energy to satellites?
-
UV-C
-
X-rays
-
Visible light
-
Gamma rays
Correct Answer
A. Visible lightExplanation
Solar energy for satellites is primarily harnessed from the region of the electromagnetic spectrum known as visible light or more specifically, from the visible and near-infrared portion of the spectrum. Sunlight, which provides the energy source for solar panels on satellites, primarily consists of photons in the visible and near-infrared wavelengths.Rate this question:

- 6.
Which of the following is not a function of solar-powered satellites?
-
Weather monitoring
-
Communications
-
Astronomical observations
-
Global positioning system (GPS)
Correct Answer
A. Astronomical observationsExplanation
Astronomical observations are not a typical function of solar-powered satellites. Solar-powered satellites are primarily designed for functions such as providing power for spacecraft, weather monitoring, communications, and supporting global positioning systems (GPS). Astronomical observations are typically conducted by specialized space telescopes and observatories like the Hubble Space Telescope, which are equipped with instruments specifically designed for studying celestial objects and phenomena.Rate this question:

Where are most solar-powered satellites positioned?
-
Low Earth orbit (LEO)
-
Geostationary orbit (GEO)
-
Polar orbit
-
Heliocentric orbit
Correct Answer
A. Geostationary orbit (GEO)Explanation
Most solar-powered satellites are positioned in geostationary orbit (GEO). A geostationary orbit is located approximately 35,786 kilometers (22,236 miles) above the Earth's equator. Satellites in this orbit appear to remain fixed in the same position relative to the Earth's surface, making them ideal for applications like communication, weather monitoring, and broadcastingRate this question:

Which mission utilized solar-powered satellites to study the Sun?
-
STEREO
-
Cassini-Huygens
-
Voyager 1
-
Apollo 11
Correct Answer
A. STEREOExplanation
The mission that utilized solar-powered satellites to study the Sun is the "STEREO" mission, which stands for Solar Terrestrial Relations Observatory. STEREO consisted of two nearly identical spacecraft, STEREO-A and STEREO-B, which were launched in 2006.Rate this question:
-
- 9.
How does gravity affect solar-powered satellites in space?
-
It helps stabilize their orbit
-
It increases solar energy absorption
-
It slows down their movement
-
It limits their operational lifespan
Correct Answer
A. It helps stabilize their orbitExplanation
Gravity plays a key role in maintaining the orbits of solar-powered satellites, helping them stay in their desired positions for communication, Earth observation, and various other functions.Rate this question:
