Слайд 6


When exposed to a microgravity environment humans experience many side effects. When exposed to a microgravity environment humans experience many side effects. Headward fluid shift or “Puffy Face” is the first effect noticed as the absence of gravity allows blood to move from the lower body to the head.

Слайд 11


The Vestibular System maintains balance by sending information to the brain about position and movement by sensing gravity. The Vestibular System maintains balance by sending information to the brain about position and movement by sensing gravity. In microgravity the vestibular system becomes confused and astronauts can experience dizziness and space motion sickness. As astronauts adapt to the microgravity environment they begin to rely on visual sensory input for reference.

Space Motion Sickness is experienced by more than 50% of all astronauts during their first few days exposure to microgravity. Space Motion Sickness is experienced by more than 50% of all astronauts during their first few days exposure to microgravity. It results in nausea and vomiting and is detrimental to crew performance.

The spacecraft or space station must provide a pressurised environment, safe air and drinking water. The spacecraft or space station must provide a pressurised environment, safe air and drinking water. The environment must be monitored to avoid microbial contamination this leads to a decrease in the astronaut’s immune function.

The long term effects of radiation exposure are much more dangerous to astronauts. The long term effects of radiation exposure are much more dangerous to astronauts. The passage of a charged particle through a cell causes ionisation of the cellular structure causing cell death. Most dangerous is the non-lethal mutation of DNA molecules which can lead to cancer.

As human space flight moves from relatively short term missions into long duration space flight like the 3 year trip to Mars we must study the effect of long term exposure to the space environment.

In order to understand the effect of space on biology scientists study plants and animals in space. In order to understand the effect of space on biology scientists study plants and animals in space. This is important not only for biological study but also for investigating plants for food and environmental functions in space.
