Questions & Answers

Q: Why do astronauts need sunscreen in space?

Astronauts need sunscreen in space to protect themselves from high levels of ionizing radiation emitted by the Sun.

Q: How does melanin protect against radiation?

Melanin absorbs and scatters ionizing radiation, shielding cells from DNA damage, and potential harm caused by radiation exposure.

Q: What are the risks of high radiation levels in space?

High radiation levels in space can increase the risk of cancer, radiation poisoning, and even death for astronauts.

Q: How are scientists developing sunscreen for astronauts?

Scientists are studying melanin's protective properties and are working on synthetic melanin enriched with selenium to provide better protection against radiation.
