The field and topic i chose to talk about is aerospace engineering and focusing mainly on the cost of space travel to foreign planets, Is deep-space travel possible? And how the ships propulsion systems will help them travel long distances efficiently? With technological advances everyday it seems to many that some day man will have sustainable life on foreign planets. This leads us into challenging out engineers and scientists everyday to a ship that can travel such a distance. For example, designing a deep-space ship requires systems in which will keep the crew members alive and healthy for the long trek through space, like a recycling oxygen system. Another key attribute to the long travel is how can the ship get them to their destination as efficiently as possible, this pushes engineers to push the limits of antigravity propulsion systems more than they ever had before. After extensively researching through deep space articles i believe that i have found two key articles that help understand and reinforce the questions that i have put forth. The two articles that i will be using are “Human Deep-Space Travel and Colonization: Technical Issues” and “Products from NASA's in-space propulsion technology program applicable to low-cost planetary missions”. Both of these articles cover the main topic that i will be further explaining in my paper on deep-space travel.

First article: the development of a super rocket for future ventures into space, and the technical logistics and the likely costs of long-term, deep-space travel add to the biological problems to be addressed.

Articles Specifics:

The main purpose of the article “Human Deep-Space Travel and Colonization: Technical Issues” is to make a point that deep-space human colonization is possible but also evaluates the issues that come with it. With the advancements in aerospace technology scientist and engineers have figured out ways for human to remain in outer space for much longer time periods than they already have, like creating oxygen generating systems, microcosmic growth of crops for consumption, ships capacity...etc. Next the second article “Products from NASA's in-space propulsion technology program applicable to low-cost planetary missions” focuses on the primary costs of planetary science missions and how to make the ships more efficient. This includes the advances in chemical and electrical propulsion systems. More importantly the development of solar electrical propulsion for long distance trips at a much lower cost. The solar propulsion systems also allow for a more efficient and faster travel to outer planets. Allowing aerospace engineers to need less engines which in return leads to reducing total costs.
