Interplanetary Logistics - Essay Example The reality is that human interaction with space was once consider a fantasy that was not remotely possibly, yet we are now perhaps only a few generations from being able to make that fantasy become reality (Bainbridge 2009). Space is largely seen as a mechanism by which we can increase our existing supply train. As such, the process by which modern civilisation conducts sustainable space exploration in the future will depend directly on an innate ability to effectively manage the supply chain, leading to a discussion centring on interplanetary logistics. The process by which this is undertaken today takes on a drastically different shape than it did during the original Apollo moon missions. During those early attempts at space exploration, required materials and tools were simply carried along for the wide. Future space exploration, however will depend on a complex network focused on the supply chain that enables sustainable colonisation based upon resources being available to people in real time, as they are needed, rather than simply relying on this on a mission by mission basis. This process will soon begin a new with scheduled missions to the moon beginning in the year 2020. The moon will literally become in a stepping off point for exploration deeper into space, and the vision is to have it become a supply command post where supplies and other associated items in terms of logistics are planned for in advance and are available as needed. No longer will astronauts be forced to rely only on what they can carry, but the objective is to have a system of logistics in place where needs are not only anticipated, but provided for in advance in order to keep the work going. This is a critical concept in terms of interplanetary travel due to the reality that lost or misplaced items can literally take months to replace, costing the crew valuable time to conduct experiments and get

Discuss the relationship between modes of production (foraging, Essay

Discuss the relationship between modes of production (foraging, pastoralism, horticulture, agriculture and industry) and gender - Essay Example Some women, therefore, have endured a lot of difficulties and have performed different duties that include fetching water in rivers and dams that are far from their homes. Some take the sole responsibilities to feed the families despite having husbands. Some societies overburden certain gender, for example, with the pastoralists; the young men travel very far to graze the livestock’s while their fathers just stay behind to just rest and sleep at home. O’Hara (278) puts across that women seem to be at bar with men when they share duties with them. In most societies, men’s and women’s duties and responsibilities are strictly defined and one gender can’t undertake the task assigned to the other gender. Women duties are strictly women duties and the same is fair about men’s role. It used to be seen in both America and Europe that it is natural for women to be taking care of homes and caring for the children while men are the breadwinners of the f amily, that is how their cultures define gender roles (Brettell and Sargent 120). With the background of United States and Europe being industrial nations, men perform the difficult task of running the industries. Men are involved in manual activities that include running of the industries (Brettell and Sargent 121). ... Therefore, women were subordinate to women. With such situation, women suffer a lot because, even if their husbands abuse them, they have little options due to their dependency (Brettell and Sargent 120). In these societies of Europe and America that are predominantly agriculturally industrial, there was certain gender inequality; men were paid more for the same job which the woman did. Women also hold positions that are low with men taking the positions of managers and directors within industries. With men dominating having the decision making vote in these industries, they did little to fight for the rights of women. According to Brettell and Sargent (119) in their book titled â€Å"Gender in Cross-Cultural Perspective†, in spite of gender inequality such industrial countries have been labeled as the most egalitarian of human societies. Brettell and Sargent (120) break down four reasons for this division of labor: the variability in the supply of game, different skills requi red for hunting and gathering, incompatibility between carrying burdens and hunting, and small size of semi-nomadic foraging populations. According to O’Hara (278), both men and women in foraging societies enjoy equal status because women gathering contribute huge portion of family diet while hunting is sometimes not reliable. The gathering role taken by women helped elevate the status of the women in these societies. But according to Brettell and Sargent (120), in the societies that hunt and fish, the status of women is low. In fact among these societies, the role is not clearly defined according to O’Hara book. There are therefore several instances where women and men hunt and gather together taking the society to a notch higher in
