More affordable access to space is needed to bring down the cost of using space for communications, reconnaissance, and civil remote sensing; opening space for experimentation and processing; and learning about living in space in preparation for human space exploration. A number of important reports in recent years have identified lowering the cost of access to space as one of the highest national aerospace priorities.

The statement of task for this study see Appendix A requested that the committee address the methodologies used in the current cost estimates for a reusable booster system RBS , including the modeling methodology used to frame the business case for an RBS. As discussed in Chapter 2 , the savings associated with use of an RBS for a national security payload manifest of 8 to 10 launches per year is estimated to be up to 50 percent of the current prices being paid by the Air Force for EELV services. If an affordable RBS can be developed, these significant cost savings can be realized. This logical conclusion is supported using the cost history for fully developed EELVs—that is, recurring cost per launch. The 70 percent hardware cost is a weighted approximation average for all expendable launch vehicles listed above.

Unlike jet engines, which operate on the same action-reaction principle but obtain the oxygen needed for burning their fuel from the atmosphere, rockets carry with them their own oxidizing agent. In that way, they can operate in the vacuum beyond the atmosphere. Achieving a balance among these three factors is challenging. Most often, propellant makes up 80 percent or more of the total weight of a launch vehicle—spacecraft combination prior to launch. When the first-stage propellants are used up, that stage is detached from the remaining parts of the launch vehicle and falls back to Earth, either into the ocean or onto sparsely populated territory. With the weight of the first stage gone, a second stage, with its own rocket engines and propellants, continues to accelerate the vehicle.

Satellite Communication - Launching

Multistage launch vehicles are employed to place spacecraft and satellites in their operational orbits. Trajectory optimization of their ascending path is aimed at defining the maximum payload mass at orbit injection, for specified structural, propulsive, and aerodynamic data. This work describes and applies a method for optimizing the ascending path of the upper stage of a specified launch vehicle through satisfaction of the necessary conditions for optimality. The method at hand utilizes a recently introduced heuristic technique, that is, the particle swarm algorithm, to find the optimal ascent trajectory.

Джабба почувствовал, что она медлит с ответом, и снова нахмурился.  - Ты так не считаешь.

 Забудьте про пленку, - сказал Бринкерхофф.  - Вводите ключ и кончайте со всем. Джабба вздохнул. На сей раз голос его прозвучал с несвойственным ему спокойствием: - Директор, если мы введем неверный ключ… - Верно, - прервала его Сьюзан.  - Если Танкадо ничего не заподозрил, нам придется ответить на ряд вопросов. - Как у нас со временем, Джабба? - спросил Фонтейн. Джабба посмотрел на ВР.

Фонтейну нужно было какое-то прикрытие - на всякий случай, - и он принял необходимые меры. ГЛАВА 113 - Ни в коем случае! - крикнул мужчина с короткой стрижкой, глядя в камеру.  - У нас приказ.

    ELVs typically consist of several rocket stages that are discarded sequentially as their fuel is exhausted and the vehicle gains altitude and speed.
