Starship Flight Test 2
Starship flight test 2 was the second flight test of the SpaceX Starship launch vehicle. SpaceX performed the flight test on November 18, 2023. The mission's primary objectives were for the vehicle to Multistage_rocket#Hot-staging, hot stage—a new addition to Starship's flight profile—followed by the second stage attaining a transatmospheric orbit, near-orbital trajectory with a controlled atmospheric reentry, reentry over the Pacific Ocean, while the booster does a boostback burn with a propulsive splashdown in the Gulf of Mexico. The vehicle successfully lifted off under the power of all 33 SpaceX_Raptor, Raptor engines on the SpaceX Super Heavy, Super Heavy Booster and made it through separation event, stage separation. The booster was planned to land on the Gulf of Mexico, but experienced multiple engine failures and exploded during its boostback burn. The Starship second stage continued to accelerate for over 8 minutes, reaching an altitude of . Towards the end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SpaceX Starship (spacecraft)
Starship is a spacecraft and Upper stage, second stage under development by American aerospace company SpaceX. Stacked atop its booster, SpaceX Super Heavy, Super Heavy, the pair compose SpaceX's Super heavy-lift launch vehicle, super heavy-lift space vehicle, also called SpaceX Starship, Starship. The spacecraft is designed to transport both crew and cargo to a variety of destinations, including Earth orbit, the Moon, and Mars. It is designed to be Reusable spacecraft, reusable and capable of Propulsive landing, landing propulsively by firing its engines to perform a controlled descent into the arms of a tower on Earth or with landing legs on other planetary bodies. It is intended to enable long-duration Interplanetary spaceflight, interplanetary flights with a crew of up to 100 people. It is also claimed by SpaceX to be capable of enabling travel to anywhere on Earth in under an hour. Furthermore, it has been proposed to be used to Orbital propellant depot, refuel other Starship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space
Space is a three-dimensional continuum containing positions and directions. In classical physics, physical space is often conceived in three linear dimensions. Modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as '' spacetime''. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as '' curved'', rather than '' flat'', as in the Euclidean space. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Communications Commission
The Federal Communications Commission (FCC) is an independent agency of the United States government that regulates communications by radio, television, wire, internet, wi-fi, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security. The FCC was established pursuant to the Communications Act of 1934 to replace the radio regulation functions of the previous Federal Radio Commission. The FCC took over wire communication regulation from the Interstate Commerce Commission. The FCC's mandated jurisdiction covers the 50 states, the District of Columbia, and the territories of the United States. The FCC also provides varied degrees of cooperation, oversight, and leadership for similar communications bodies in other countries in North America. The FCC is funded entirely by regulatory fees. It has an estimated fiscal-2022 budg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federal Aviation Administration
The Federal Aviation Administration (FAA) is a Federal government of the United States, U.S. federal government agency within the United States Department of Transportation, U.S. Department of Transportation that regulates civil aviation in the United States and surrounding international waters. Its powers include air traffic control, certification of personnel and aircraft, setting standards for airports, and protection of U.S. assets during the launch or re-entry of commercial space vehicles. Powers over neighboring international waters were delegated to the FAA by authority of the International Civil Aviation Organization. The FAA was created in as the Federal Aviation Agency, replacing the Civil Aeronautics Administration (United States), Civil Aeronautics Administration (CAA). In 1967, the FAA became part of the newly formed U.S. Department of Transportation and was renamed the Federal Aviation Administration. Major functions The FAA's roles include: *Regulating U.S. co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Separation Event
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket ''stages'', each of which contains its own engines and propellant. A ''tandem'' or ''serial'' stage is mounted on top of another stage; a ''parallel'' stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched. By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased. Each successive stage can also be optimized for its specific operating conditions, such as decreased atmospheric pressure at higher altitudes. This ''staging'' allows the thrust of the remaining stages to more easily accelerate the rocket to its final velocity and height. In serial or tandem staging schemes, the first stage is at the bottom and is usually the largest, the second stage and subse ...

SpaceX Raptor
Raptor is a family of rocket engines developed and manufactured by SpaceX. It is the third rocket engine in history designed with a Staged combustion cycle#Full-flow staged combustion cycle, full-flow staged combustion fuel cycle, and the first such engine to power a vehicle in flight. The engine is powered by cryogenic Methane#Rocket propellant, liquid methane and liquid oxygen, a combination known as Liquid rocket propellant#Methane, methalox. SpaceX's super heavy-lift launch vehicle, super-heavy-lift SpaceX Starship, Starship uses Raptor engines in its SpaceX Super Heavy, Super Heavy booster and in the SpaceX Starship (spacecraft), Starship second stage. Starship missions include lifting payloads to Earth orbit and is also planned for missions to the Starship HLS, Moon and SpaceX Mars program, Mars. The engines are being designed for reuse with little maintenance. Design Raptor is designed for extreme reliability, aiming to support the airline-level safety required by the p ...

Gulf Of Mexico
The Gulf of Mexico () is an oceanic basin and a marginal sea of the Atlantic Ocean, mostly surrounded by the North American continent. It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo; and on the southeast by Cuba. The coastal areas along the Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are occasionally referred to as the "Third Coast" of the United States (in addition to its Atlantic and Pacific coasts), but more often as "the Gulf Coast". The Gulf of Mexico took shape about 300 million years ago (mya) as a result of plate tectonics. The Gulf of Mexico basin is roughly oval and is about wide. Its floor consists of sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Straits of Florida between the ...
