List Of Space Launch System Launches
, the Space Launch System (SLS) – a Shuttle-derived, super heavy-lift expendable launch vehicle – has conducted one successful launch, and a further four have been officially scheduled. All flights on the current launch manifest are for the Artemis program, a human spaceflight project aimed at establishing a permanent human presence on the Moon. The flights will launch from the vehicle's dedicated pad at Kennedy Space Center's Launch Complex 39B (LC-39B). The first three flights use the Block 1 configuration with a modified Delta Cryogenic Second Stage known as the Interim Cryogenic Propulsion Stage (ICPS). The Block 1B configuration with the Exploration Upper Stage (EUS) will be used starting from the fourth flight. Launches Proposed launches Later Artemis missions In early 2019, then-Associate Administrator for Human Exploration William H. Gerstenmaier drafted a proposal for three more launches of SLS Block 1B launch vehicles beyond Artemis 5 in support of the A ...

Skylab II
''Skylab II'' was a space station concept proposed in 2013 by the Advanced Concepts Office of NASA Marshall Space Flight Center The George C. Marshall Space Flight Center (MSFC), located in Redstone Arsenal, Alabama (Huntsville postal address), is the U.S. government's civilian rocketry and spacecraft propulsion research center. As the largest NASA center, MSFC's first ..., to be located at the Earth-Moon system, Earth-Moon Lagrangian point#L2, L2 Lagrangian point. Proposed by NASA contractor Brand Griffin, ''Skylab II'' would have been constructed as a "wet workshop" using a spent multistage rocket, upper-stage hydrogen fuel tank from the Space Launch System (SLS), much as the ''Skylab'' was originally planned to be built "wet" from the spent bipropellant#Types, bipropellant tanks of the Saturn (rocket family), Saturn S-IVB upper stage. If constructed, ''Skylab II'' would have been the first crewed outpost located beyond the orbit of the Moon. Space station design ''Skyla ...

Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos and Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a large impact feature. Days and seasons on Mars are comparable to those of Earth, as the planets have a similar rotation period a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Segmented Mirror
A segmented mirror is an array of smaller mirrors designed to act as segments of a single large curved mirror. The segments can be either spherical or asymmetric (if they are part of a larger parabolic reflector). They are used as objectives for large reflecting telescopes. To function, all the mirror segments have to be polished to a precise shape and actively aligned by a computer-controlled active optics system using actuators built into the mirror support cell. The concept was pioneered by Guido Horn D'Arturo, who built the first working segmented mirror in 1952, after twenty years of research; It was later independently rediscovered and further developed under the leadership of Dr. Jerry Nelson at the Lawrence Berkeley National Laboratory and University of California during the 1980s, and since then all the necessaries technologies have spread worldwide to the point that essentially all future large optical telescopes plan to use segmented mirrors.
