SpaceX Fairing Recovery Program
The SpaceX fairing recovery program was an experimental program by SpaceX, begun in 2017 in an effort to determine if it might be possible to economically recover and reuse expended launch vehicle payload fairings from suborbital space. The experimental program became an operational program as, by late 2020, the company was routinely recovering fairings from many flights, and by 2021 were successfully refurbishing and reflying previously flown fairings on the majority of their satellite launches. During the early years of the program, SpaceX attempted to catch the descending payload fairings, under parachute, in a very large net on a moving ship in the Atlantic ocean east of the Space Coast of Florida. Two former platform supply vessels—''Ms.Tree'', formerly known as ''Mr.Steven'', and its sister ship, ''Ms.Chief''—were chartered by SpaceX and used 2018–2021 as experimental platforms for recovery of rocket fairings from Falcon 9 orbital launch trajectories. These f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first trans-Atlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code abbreviations to denote the various individual stations on the line (for instance, AX could represent Halifax). "N" and two letters would identify U.S. Navy; "M" and two letters would be a Marconi station. On A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falcon Heavy
Falcon Heavy is a partially reusable heavy-lift launch vehicle that is produced by SpaceX, an American aerospace manufacturer. The rocket consists of two strap-on boosters made from Falcon 9 first stages, a center core also made from a Falcon 9 first stage, and a second stage on top. Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA's Space Launch System and the fourth-highest capacity of any rocket to reach orbit, trailing the Saturn V, Energia (rocket), Energia and Space Launch System. SpaceX conducted Falcon Heavy test flight, Falcon Heavy's maiden launch on 6 February 2018, at 20:45 Coordinated Universal Time, UTC. The rocket carried Elon Musk's Tesla Roadster belonging to SpaceX founder Elon Musk, with a dummy dubbed "Starman" in the driver's seat, as a boilerplate (spaceflight), dummy payload. The second Falcon Heavy launch occurred on 11 April 2019, and all three booster rockets successfully returned to Earth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Test Article (aerospace)
A test article or pathfinder is a version of spacecraft or related vehicle or equipment, built as a platform to perform testing on particular portions of a spaceflight regime. Test articles are built to the specifications necessary to replicate particular conditions and behaviors that are to be validated. Test articles may be built for flight testing or for non-flight testing. For space agencies with extensive flight certification procedures, they may be built without the certification and quality control steps taken with the versions intended for flight. Test articles are more complete than a boilerplate. Overview Some test articles are theoretically able to be modified and upgraded to flight-ready status. Of the 136 Space Shuttle external fuel tanks produced, one was retained as a test article. The contractor producing the tanks stated that that tank could be refurbished for flight use if necessary. Test articles are often displayed in museums because of their accuracy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest eviden ...

Flight Test
Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing aircraft behaviour and systems. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or Atmosphere of Earth, atmospheric testing of launch vehicles and Reusable launch vehicle, reusable spacecraft. This data is validated for accuracy and analyzed before being passed to specialist engineering groups for further analysis to Verification and validation, validate the design of the vehicle. The flight test phase accomplishes two major tasks: 1) finding and fixing any Aeronautics, design problems and then 2) verification and validation, verifying and documenting the vehicle capabilities for government certification or customer acceptance. The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a ...

SpaceX Dragon 2
Dragon 2 is a class of partially reusable spacecraft developed and manufactured by American aerospace manufacturer SpaceX, primarily for flights to the International Space Station (ISS). SpaceX has also launched private missions such as Inspiration4 and Axiom Mission 1. There are two variants: Crew Dragon, a spacecraft capable of ferrying four crew, and Cargo Dragon, an updated replacement for the original Dragon 1. The spacecraft consists of a reuseable space capsule and an expendable trunk module. The spacecraft launches atop a Falcon 9 Block 5 rocket and the capsule returns to Earth via splashdown. Cargo Dragon supplies cargo to the ISS under a Commercial Resupply Services-2 contract with NASA. The first flight of Dragon 2 in a cargo configuration launched in December 2020. It shares this duty with Northrop Grumman Innovation Systems' Cygnus spacecraft, and Sierra Nevada Corporation's Dream Chaser spacecraft is expected to join them . , Crew Dragon is the only U.S ...

Demo-2
Crew Dragon Demo-2 (officially Crew Demo-2, SpaceX Demo-2, or Demonstration Mission-2) was the first crewed test flight of the Crew Dragon spacecraft. The spacecraft, named '' Endeavour'', launched on 30 May 2020 on a Falcon 9 booster, and carried NASA astronauts Douglas Hurley and Robert Behnken to the International Space Station in the first crewed orbital spaceflight launched from the United States since the final Space Shuttle mission in 2011, and the first ever operated by a commercial provider. Demo-2 was also the first two-person orbital spaceflight launched from the United States since STS-4 in 1982. Demo-2 completed the validation of crewed spaceflight operations using SpaceX hardware and received human-rating certification for the spacecraft, including astronaut testing of Crew Dragon capabilities on orbit. Docking was autonomously controlled by the Crew Dragon, but monitored by the flight crew in case manual intervention became necessary. The spacecraft soft docked ...
