Challenges for Space Exploration

How does the challenge of microgravity compare to the challenge of space radiation?

• Microgravity affects astronauts’ muscles, while radiation exposure increases cancer risk.

• Microgravity makes communication harder, while radiation affects spacecraft function.

• Both challenges primarily impact spacecraft design.

• Space radiation is easier to manage than microgravity.

How is the challenge of distance similar to the challenge of cost in space exploration?

• Both require advanced technology to solve.

• Distance is a problem only for astronauts, while cost only affects engineers.

• Both prevent space exploration from advancing quickly.

• Cost is more difficult to overcome than distance.
