SpaceX Starship Integrated Flight Test 3
Starship flight test 3 was the third flight test of the SpaceX Starship launch vehicle. SpaceX performed the flight test on March 14, 2024. Starship successfully completed a full-duration second stage burn, reaching the intended orbital velocity for the first time, but broke up during re-entry in the atmosphere. Background Changes from the previous flight After the second flight test in November 2023 ended in the destruction of both the SpaceX Super Heavy, Super Heavy booster and the SpaceX Starship (spacecraft), Starship spacecraft, 17 significant changes were made to the vehicles, including upgrading the ship to an electric Thrust vectoring, thrust vector control (TVC) system (the booster had received similar upgrades for the second flight test) and delaying the vent of liquid oxygen (LOX) to after Starship engine cutoff (SECO). SpaceX upgraded the orbital tank farm with additional subcoolers and pumps to increase the propellant flow rate. In addition, two water tanks w ...

Furthermore, it has been proposed to be used to Orbital propellant depot, refuel other Starship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hesco Bastion
The Concertainer, known colloquially as the Hesco barrier or Hesco bastion, with HESCO being the brand name of the manufacturer, is a modern gabion primarily used for flood control and military fortifications. It is made of a collapsible wire mesh container and heavy-duty fabric liner and is used as a temporary to semi-permanent levee or blast wall against small-arms fire and/or explosives. It has been used during the war on terror in Iraq and Afghanistan. It was originally designed for use on beaches and marshes for erosion and flood control. They were used in 2005 to reinforce levees around New Orleans in the weeks between Hurricane Katrina and Hurricane Rita. During the June 2008 Midwest floods, of HESCO barrier wall were shipped to Iowa. In late March 2009, of HESCO barrier were delivered to Fargo, North Dakota, to protect against floods. In late September 2016, of HESCO barriers were used in Cedar Rapids, Iowa, for the fall flood of 2016. Development The Concertaine ...

Atmospheric Entry
Atmospheric entry (sometimes listed as Vimpact or Ventry) is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. Atmospheric entry may be ''uncontrolled entry,'' as in the entry of astronomical objects, space debris, or bolides. It may be ''controlled entry'' (or ''reentry'') of a spacecraft that can be navigated or follow a predetermined course. Methods for controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass ( ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Objects have reentered with speeds ranging from 7.8 km/s for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propellant
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or another motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel a ...

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 ...

Water Landing
In aviation, a water landing is, in the broadest sense, an aircraft landing on a body of water. Seaplanes, such as floatplanes and flying boats, land on water as a normal operation. Ditching is a controlled emergency landing on the water surface in an aircraft not designed for the purpose, and it is a very rare occurrence. Controlled flight into the surface and uncontrolled flight ending in a body of water (including a runway excursion into water) are generally not considered water landings or ditching, but are considered accidents. Most times, ditching results in aircraft structural failure. Aircraft water landings By design Seaplanes, flying boats, and amphibious aircraft are designed to take off and alight on water. Alighting can be supported by a hull-shaped fuselage and/or pontoons. The availability of a long effective runway was historically important on lifting size restrictions on aircraft, and their freedom from constructed strips remains useful for transportat ...

South Texas
South Texas is a geographic and cultural region of the U.S. state of Texas that lies roughly south of—and includes—San Antonio. The southern and western boundary is the Rio Grande, and to the east it is the Gulf of Mexico. The population of this region is more than 5 million according to the 2024 census estimates. The southern portion of this region is often referred to as the Lower Rio Grande Valley, Rio Grande Valley. The eastern portion along the Gulf of Mexico is also referred to as the Texas Coastal Bend, Coastal Bend. Greater Houston and Beaumont–Port Arthur metropolitan area, Beaumont–Port Arthur are occasionally tied to the region, both for physically being on the southern end of the state and for businesses that use "South Texas" in its name. (i.e. South Texas College of Law Houston, South Texas School of Law, South Texas State Fair, etc.). However, the two are more commonly associated with East Texas or Southeast Texas. Geography There is no defined northern bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SpaceX Starbase

Wet Dress Rehearsal
Launch vehicle system tests assess the readiness of a launch system to safely reach orbit. Launch vehicles undergo system tests before they launch. Wet dress rehearsals (WDR) and more extensive static fire tests prepare fully assembled launch vehicles and their associated ground support equipment (GSE) prior to launch. The spacecraft/payload may or may not be attached to the launch vehicle during the WDR or static fire, but sufficient elements of the rocket and all relevant ground support equipment are in place to help verify that the rocket is ready for flight. Propellant load tests and static fire tests may also be done on prototype rocket stages, in which case no fully assembled launch vehicle is involved, as is the case of the SpaceX Starship stages, the booster Super Heavy and the second stage Starship. Wet dress rehearsal A wet dress rehearsal is called "wet" because the liquid propellant components (such as liquid oxygen, liquid hydrogen, etc.) are loaded into the rocket ...
