NASA uses a variety of fuels depending on the mission and type of spacecraft. For rocket launches, common fuels include liquid hydrogen and liquid oxygen for the Space Launch System (SLS) and the Space Shuttle's main engines, while solid rocket boosters use a composite propellant. Other missions may utilize hydrazine for thrusters and various other fuels for smaller spacecraft. The choice of fuel is based on efficiency, safety, and mission requirements.

The principle of design that refers to creating a center of attraction in a space is called "emphasis." Emphasis involves highlighting a specific area or element, making it the focal point of the design, and giving it purpose. This can be achieved through contrast, color, scale, or placement, guiding the viewer's attention and enhancing the overall composition.

Neil Armstrong resigned from NASA in 1971, citing a desire to pursue a career in academia and private industry. After his historic Apollo 11 moon landing, he felt a strong pull towards teaching and contributing to aerospace engineering. His departure marked the end of his formal association with space exploration, although he remained an influential figure in the field. Armstrong's decision reflected a personal choice to step away from public life after achieving his monumental accomplishments.

In the future, NASA plans to focus on ambitious projects, including the Artemis program, which aims to return humans to the Moon by the mid-2020s and establish a sustainable presence there. The agency is also working on the Mars Sample Return mission, which seeks to bring samples from the Martian surface back to Earth. Additionally, NASA will continue to advance its Earth science missions and develop technologies for future deep-space exploration, including crewed missions to Mars in the 2030s. Overall, NASA's future endeavors will emphasize international collaboration, scientific discovery, and technology innovation.
