Cutting Costs in Space Exploration: Rockets vs Elevators

2129 Words5 Pages

The two main technologies that are working towards cutting down the costs of space exploration are reusable rockets and the space elevator. Both of these ideas will cut down on the cost of getting payloads to orbit. The idea of reusable rockets means that space programs wouldn’t have to make new rockets for each launch. The idea of the space elevator would allow better payload efficiency and easier access to space, because it wouldn’t have to deal with fuel or the obstacle of gravity. Even though the space elevator may take more time than the more well known reusable rockets it is still the best way to cut down on costs of space exploration in the future. Although reusable rockets are the current preference for reduced costs, the space elevator …show more content…

The overall cost reduction of building a space elevator would far outweigh the possible negatives of not pursuing this project further. A space elevator can significantly cut the cost of getting a payload to orbit. Traditional rockets average twenty thousand dollars per kilogram of payload while a space elevator could cut it down to as little as ten dollars per kilogram of payload. This is a reduction of over 99.9%, and according to Edward C. Bradley, in “A Space Elevator Based Exploration Strategy,” a fully functioning space elevator could “have gross revenues of around $2.2B per year (based on 50% market capture).” Within 5 years the entire project could be reimbursed to the government and start providing money for NASA to do even more space research. With the massive cost reduction, almost every nation or company around the world could get a satellite for research, manufacturing or tourism. This would help boost the economy of the world and lead to easier space travel. The easier space travel would let scientists research our solar system and space much easier, leading to better technology for the human race to use. Better technology leads countries to finding more efficient ways for the space elevators and space travel in general. This would become never ending loop of improvement for the U.S. and the entire world. NASA …show more content…

The carbon nanotubes have yet to be used in long strands like this project would require. Along with this, the manufacturing price of these nanotubes is tremendously high; resulting in an estimated cost of ten billion dollars. That is roughly fifty-six percent of NASA’s budget in the 2015 year. In addition, Edward C. Bradley in, “The Space Elevator,” says that, “Hazards to the SE include winds, lightning and aircraft in the troposphere; atomic oxygen in the upper atmosphere; and radiation, solar storms, orbital debris, orbiting satellites and meteorites in the magnetosphere.” The carbon nanotubes may not be completely ready yet but with the advances that scientists have been making each year it is possible for the U.S. to start and finish work on the space elevator within ten to twenty years. These advancements would also lead to cheaper production costs, which would cut down drastically on the entire project's budget. Even if we can’t reduce the cost of the first space elevator, the ten billion dollars used in construction is significantly less than one percent of the U.S. government’s total budget in 2015 and it would be spread out over multiple years. The U.S. government has spent more time, money, and effort on less world changing things, such as politician’s paychecks, interest on our national debt, and the “Bridge to Nowhere” in Alaska.
