What is the function of the photovoltaic cells in solar panels?
- A.
To generate microwaves
- B.
To transmit Wi-Fi signals
- C.
To convert solar energy into electricity
- D.
To measure atmospheric pressure
Correct Answer
C. To convert solar energy into electricityExplanation
Photovoltaic cells, commonly referred to as solar cells, play a crucial role in solar panels. Their primary function is to convert sunlight into electricity. When sunlight (photons) strikes the surface of the photovoltaic cells, it excites electrons within the material, creating an electric current. This phenomenon is known as the photovoltaic effect.Rate this question:

Which satellite was the first to be powered by solar energy?
- A.
Sputnik 1
- B.
International Space Station
- C.
Hubble Space Telescope
- D.
Vanguard 1
Correct Answer
D. Vanguard 1Explanation
The first satellite to be powered by solar energy was the "Vanguard 1" satellite. Vanguard 1, launched by the United States on March 17, 1958, was one of the earliest artificial satellites in space and featured small solar panels to generate electricity from sunlight.Rate this question:

What happens to excess solar energy generated by the satellite?
- A.
It is wasted
- B.
It is stored in onboard batteries
- C.
It is transmitted back to Earth
- D.
It is converted into heat and radiated into space
Correct Answer
B. 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:

Which region of the electromagnetic spectrum provides solar energy to satellites?
- A.
UV-C
- B.
X-rays
- C.
Visible light
- D.
Gamma rays
Correct Answer
C. 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:

Which of the following is not a function of solar-powered satellites?
- A.
Weather monitoring
- B.
Communications
- C.
Astronomical observations
- D.
Global positioning system (GPS)
Correct Answer
C. 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?
- A.
Low Earth orbit (LEO)
- B.
Geostationary orbit (GEO)
- C.
Polar orbit
- D.
Heliocentric orbit
Correct Answer
B. 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:

- B.
Cassini-Huygens
- C.
Voyager 1
- D.
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:
