Subject: 500 Word Summary of The Article about Deep Space Exploration Space Transportation Systems and Control Technology
The following memo is a 500-word summary about an overview about deep space exploration space transportation systems. The article mentions how deep space exploration missions are calling for a new development of space transportation systems and reviews current deep space exploration transportation systems. Space transportation technology before only allowed humans to explore the Moon but with different countries’ space development programs humans are now able to travel and study planets that are lightyears away from Earth. Even now humans are still developing new space transportation systems that will allow them to explore the deep galaxy and travel beyond its current limited distance. According to the article, “Development of deep space explorations is in full swing, the future deep-space missions about nearly halfway are through international cooperation and organization with low cost, high efficiency to achieve more distance future deep space exploration.”, our goal is to continue to create new space transportation systems that allow humans to go further into space.
Space transportation systems are classified as the following: expendable launch vehicle and Reusable Lauch Vehicle (RLV). Space transportation systems rely on both classifications. Expanded launch vehicle’s primary purpose is to enter an attached component into space and then the rockets that performed the launched are discarded after reaching its distance. In the upper stage of the rocket, a reusable launch vehicle is used to carry out it’s space mission and reach its destination. Deep space exploration is not as simple as sending a rocket into space. There are tremendous considerations that are implemented into the overall function and designs of space transportation systems and these considerations ensure that the rockets can travel deep into the solar systems.
Some of the problem that are included in deep space exploration are management technology for long flying time, thrust regulations, autonomous navigations, and reliable electrical systems. Deep space exploration mission are large scales which put heavy demands on control system reliability. By increasing the flying time, it brings challenges to the reliability of the control system. To keep the system reliable and resilient over long periods of flight, fault detections and execution of sensitive equipment will be performed to keep up with the high reliability, flying time and multiple task demand. These performances are stress test which will give developer an idea on what are rockets current limitations and how to overcome those limitation to perform at higher loads. Using these data analysis developer could create a newer version of a rocket that will be able to perform under heavy loads and be used in longer space exploration. Large launch vehicles use new variable thrust systems and several other working power systems which will lead to a bitter control of thrust control systems. Thrust regulations and control technology can regulate the loads of different orbits, reduce thrust for better aerodynamics loads, improve flight reliability, reduce thrust to ease separation when transitioning to different environment and improve separation accuracy with little change in the carrier state. With proper thrust regulation humans will be able to transvers through space efficiently Deep space exploration control technology has entered the testing stage to meet the development needs of future deep space explorations.
