- Dangers of Space Travel
- Radiation
- Average American recieves 6.2mSv radiation per year
- Radiation causes cancer and genetic disorders by mutating DNA
- Martian surface gives 0.67mSv per day
- If a mission stayed on Mars for 500 days, radiation dose would be 335 mSv
- Radiation dose on a 210-day journey to Mars would be 368mSv
- Combining 2 journeys' radiation with 500 days surface radiation, a mission would recieve a total of 1,071mSv
- If a mission stayed on Mars for 500 days, radiation dose would be 335 mSv
- Average dose overall would be 428.4mSv per year
- Combining 2 journeys' radiation with 500 days surface radiation, a mission would recieve a total of 1,071mSv
- Micrometeorites
- Debris from space junk or bits of dust or rock in space
- estimated 10,000 man-made objects larger than 10cm orbiting Earth
- Could rip a hole in hull of space shuttle or astronaut's suit
- Debris from space junk or bits of dust or rock in space
- Muscle atrophy
- long periods in low/0 gravity causes muscle waste
- Astronauts would need an intensive exercise programme to prevent, this would be time consuming
- effects
- heart problems, since heart is a muscle
- astronauts could be bedridden when return to Earth
- difficulty walking, back problems
- Radiation
