Relativity Space
Relativity Space is an American aerospace manufacturing company headquartered in Los Angeles, California. It was founded in 2015 by Tim Ellis and Jordan Noone. Relativity Space is developing manufacturing technologies, launch vehicles and rocket engines for commercial orbital launch services. History Relativity Space was founded in 2015 by CEO Tim Ellis and CTO Jordan Noone on the idea that existing NewSpace companies were not tapping enough into the potential of additive manufacturing (3D printing). Relativity is aiming to be the first company to successfully launch a fully 3D-printed launch vehicle into orbit. In November 2020, Relativity Space announced its US$500 million Series D funding at a calculated US$2.3 billion valuation. In June 2021 Relativity announced another US$650 million funding round led by Fidelity Investments at a valuation of US$4.2 billion, bringing its total funding to US$1.335 billion. The funding will help the development of a fully reusable m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3D Printing Processes
A variety of processes, equipment, and materials are used in the production of a three-dimensional object via additive manufacturing. 3D printing is also known as additive manufacturing, therefore the numerous available 3D printing process tend to be additive in nature with a few key differences in the technologies and the materials used in this process. Some of the different types of physical transformations which are used in 3D printing include melt extrusion, light polymerization, continuous liquid interface production and sintering. Types of 3D printing processes There are many different 3D printing processes, that can be grouped into seven categories: * Vat photopolymerization * Material jetting * Binder jetting * Powder bed fusion * Material extrusion * Directed energy deposition * Sheet lamination Each process and piece of equipment has pros and cons associated with it. These usually involve aspects such as speed, costs, versatility with respect to feedstock m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket Engine
A rocket engine uses stored rocket propellants as the reaction mass for forming a high-speed propulsive jet of fluid, usually high-temperature gas. Rocket engines are reaction engines, producing thrust by ejecting mass rearward, in accordance with Newton's third law. Most rocket engines use the combustion of reactive chemicals to supply the necessary energy, but non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Vehicles propelled by rocket engines are commonly called rockets. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum to propel spacecraft and ballistic missiles. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix of heavier species, reducing the e ...

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense.

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Stennis Space Center
The John C. Stennis Space Center (SSC) is a NASA rocket testing facility in Hancock County, Mississippi, United States, on the banks of the Pearl River at the Mississippi–Louisiana border. , it is NASA's largest rocket engine test facility. There are over 50 local, state, national, international, private, and public companies and agencies using SSC for their rocket testing facilities. History The initial requirements for NASA's proposed rocket testing facility required the site to be located between the rockets' manufacturing facility at Michoud Assembly Facility in eastern New Orleans, Louisiana, and the launch facility at the Kennedy Space Center in Florida. Also, the site required barge access as the rocket motors to be tested for Apollo were too large for overland transport. Additionally, the Apollo motors were too loud to be tested at Marshall Space Flight Center's existing test stands near Huntsville, Alabama. A more isolated site was needed. After an exhaustive site ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Cornelius Stennis (August 3, 1901April 23, 1995) was an American politician who served as a U.S. Senator from the state of Mississippi. He was a Democrat who served in the Senate for over 41 years, becoming its most senior member for his last eight years. He retired from the Senate in 1989, and is, to date, the last Democrat to have been a U.S. Senator from Mississippi. Furthermore, at the time of his retirement, Stennis was the last United States Senator to have served during the presidency of Harry S. Truman. While attending law school, Stennis won a seat in the Mississippi House of Representatives, holding office from 1928 to 1932. After serving as a prosecutor and state judge, Stennis won a special election to fill the U.S. Senate vacancy following the death of Theodore G. Bilbo. He won election to a full term in 1952 and remained in the Senate until he declined to seek re-election in 1988. Stennis became the first Chairman of the Senate Ethics Committee and also chai ...

Autonomous Robot
An autonomous robot is a robot that acts without recourse to human control. The first autonomous robots environment were known as Elmer and Elsie, which were constructed in the late 1940s by W. Grey Walter. They were the first robots in history that were programmed to "think" the way biological brains do and meant to have free will.Ingalis-Arkell, Esthe"The Very First Robot Brains Were Made of Old Alarm Clocks" 7 March 2012. Elmer and Elsie were often labeled as tortoises because of how they were shaped and the manner in which they moved. They were capable of phototaxis which is the movement that occurs in response to light stimulus. Historic examples include space probes. Modern examples include self-driving vacuums and cars. Industrial robot arms that work on assembly lines inside factories may also be considered autonomous robots, though their autonomy is restricted due to a highly structured environment and their inability to locomote. Components and criteria of robotic au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
