The Risks Of Long Distance Human Spaceflight

Decent Essays
Upon the consideration of long-distance human spaceflight, the risk management plan in correspondence must prepare the crew members before and during the mission, for risks which may or may not occur, in the isolated confines of space. Specifically, the risks of meteoroid impacts, malnutrition, and contamination were observed and their effects on the psychological and physical health of the crew members was detailed. Only meteoroid impacts are singularly and in transit risk, while both malnutrition and contamination are constant risks due to the human factor. Out the three risks listed, the most harmful risk would be of malnutrition due to the extensive consequences which can compound other problems. The main risk management method would…show more content…
Meteoroid impacts, although a common obstacle in science fiction movies, do not rank very highly on a problem for a crew on spacecraft due to the very high dispersity of streams of meteoroids, their very small size, and the very small size of a spacecraft in comparison to the vastness of space. Even the ISS has a 1 in a 10 billion chance to hit by predictable meteoroid streams while in a very small orbit (David, L. 2014). However, due to the large distance any communication signals would have to traverse, in an emergency situation the astronauts would need to be able to act according to protocol. To prepare for even this unlikely situation, crew members should undergo pre-flight and routine in-flight simulations which involve safety measures of a breached hull, compromised oxygen supply, damaged thrusters, or other mechanical failures (Phillips, T. 2002). Although considering that this risk only pertains to the in-transit portion of the mission and a meteoroid that penetrates the shell of the spacecraft in living quarters would most likely result in the immediate lack of oxygen due to the immense vacuum in space which would limit any opportunty to mediate the situation.
Nutrition, although taken care of since the introduction of multiple day missions, is the most important risk factor to consider as it directly relates the health and ability of the crew member to perform their duties. The lack of proper nutrients and vitamins can lead to increased bone
