I WONDER - How Are Space Shuttles Powered?

Space shuttles cannot rely on Earth-based electricity or batteries for long durations in space. Since the 1950s, they have used solar power, with solar panels mounted on shuttles to harness solar energy. The International Space Station (ISS) employs a more advanced form of solar panels, which are part of a foldable blanket that unfolds in space to capture sunlight, ensuring a continuous power supply.

Why can't space shuttles rely on batteries for their power needs?

• Batteries are too heavy to be used in space.

• Batteries are too expensive to produce for space missions.

• Batteries do not last long enough for extended missions.

• Batteries are not allowed in space due to safety concerns.

What was the primary method of generating power for space shuttles since the 1950s?

• Nuclear power

• Wind energy

• Solar power

• Hydroelectric power

How did the International Space Station improve upon traditional solar panels?

• By using wind turbines in space

• By making them smaller and more efficient

• By integrating them into a foldable blanket

• By using nuclear reactors instead

What is the advantage of the foldable solar panel blanket used by the International Space Station?

• It requires less maintenance than other systems.

• It reduces the weight of the shuttle significantly.

• It is cheaper to produce than traditional panels.

• It allows the station to capture more sunlight.

What ensures that the International Space Station has enough electricity in space?

• The use of wind energy captured in space

• The foldable solar panel blanket system

• The use of advanced battery systems

• The ability to plug into Earth's power grid
