Washington sources reported that the space agency's Human Research Program (HRP) used ground based analogs, laboratories, and the International Space Station (ISS), to evaluate human performance and countermeasures required for the exploration of Mars, expected to be in 2030s. Meanwhile the team divided the hazards into five classifications radiation; isolation and confinement; distance from Earth; gravity and hostile or closed environments.
NASA said in a statement on Monday "Above Earth's natural protection, radiation exposure increases cancer risk, damages the central nervous system, can alter cognitive function, reduce motor function and prompt behavioral changes". Furthermore to mitigate this, deep space vehicles will have significant protective shielding, dosimetry, and alerts.
Accordingly sleep loss, circadian
desynchronisation, and work overload compound issue isolated and confined and
may lead to performance decrements, adverse health outcomes, and compromised
mission objectives. Moreover another hazard is the distance from Earth and the
spacecraft bound to Mars will include important habitability factors such as
temperature, pressure, lighting, noise, and quantity of space. Hence it is
essential that astronauts are getting the requisite food, sleep and exercise
needed to stay healthy and happy.
World's biggest OIL supplier Saudi Arabia announced plans to cut production New Delhi sources stated that oil prices climbed on Monday as the world's biggest supplier Saudi Arabia announced plans to cut production, in the face of fears of oversupply.
