Falcon 9 v1.1
Falcon 9 v1.1 was the second version of SpaceX's Falcon 9 orbital launch vehicle. The rocket was developed in 2011–2013, made its maiden launch in September 2013, and its final flight in January 2016. The Falcon 9 rocket was fully designed, manufactured, and operated by SpaceX. Following the second Commercial Resupply Services (CRS) launch, the initial version Falcon 9 v1.0 was retired from use and replaced by the v1.1 version. Falcon 9 v1.1 was a significant evolution from Falcon 9 v1.0, with 60 percent more thrust and weight. Its maiden flight carried out a demonstration mission with the CASSIOPE satellite on 29 September 2013, the sixth overall launch of any Falcon 9. Both stages of the two-stage-to-orbit vehicle used liquid oxygen (LOX) and rocket-grade kerosene (RP-1) propellants. The Falcon 9 v1.1 could lift payloads of to low Earth orbit, and to geostationary transfer orbit, which places the Falcon 9 design in the medium-lift range of launch systems.50t payload ...

SpaceX CRS-5
SpaceX CRS-5, also known as SpX-5, was a Commercial Resupply Service mission to the International Space Station (ISS), conducted by SpaceX for NASA, and was launched on 10 January 2015 and ended on 11 February 2015. It was the seventh flight for SpaceX's uncrewed Dragon cargo spacecraft and the fifth SpaceX operational mission contracted to NASA under an ISS resupply services contract. Launch history By July 2014, the launch was scheduled by NASA for December 2014, with docking to the station projected to occur two days after launch. Originally scheduled for a 16 December 2014 launch, the mission was changed to 19 December 2014, in order to give SpaceX more preparation time for a successful launch. The launch was postponed again to 6 January 2015, in order to allow more tests before committing to a firm launch date. On 6 January 2015, the launch attempt was placed on hold at 1 minute 21 seconds prior to scheduled lift-off after a member of the launch team noticed act ...

SpaceX Dragon
American private space transportation company SpaceX has developed and produced several spacecraft named Dragon. The first family member, now referred to as Dragon 1, flew 23 cargo missions to the ISS between 2010 and 2020 before being retired. With this first version not designed for carrying astronauts, it was funded by NASA with $396 million awarded through the Commercial Orbital Transportation Services (COTS) program, with SpaceX being announced as a winner of the first round of funding on August 18, 2006. SpaceX developed its Dragon 2 spacecraft starting in 2014, with a cargo version and a crewed version. It entered service in 2019 with the Demo-1 flight, and performed its first flight with astronauts on May 30, 2020, during the Crew Dragon Demo-2 flight. SpaceX also investigated a version named Red Dragon for Mars exploration, but the project did not go forward. A version named Dragon XL Is proposed to provide Gateway Logistics Services to the Lunar Gateway. Name ...

Liquid Oxygen
Liquid oxygen—abbreviated LOx, LOX or Lox in the aerospace, submarine and gas industries—is the liquid form of molecular oxygen. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which has continued to the present. Physical properties Liquid oxygen has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of , slightly denser than liquid water, and is cryogenic with a freezing point of and a boiling point of at . Liquid oxygen has an expansion ratio of 1:861 under and , and because of this, it is used in some commercial and military aircraft as a transportable source of breathing oxygen. Because of its cryogenic nature, liquid oxygen can cause the materials it touches to become extremely brittle. Liquid oxygen is also a very powerful oxidizing agent: organic materials will burn rapidly and energetically in liquid o ...

Two-stage-to-orbit
A two-stage-to-orbit (TSTO) or two-stage rocket launch vehicle is a spacecraft in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity. It is intermediate between a three-stage-to-orbit launcher and a hypothetical single-stage-to-orbit (SSTO) launcher. At liftoff the first stage is responsible for accelerating the vehicle. At some point the second stage detaches from the first stage and continues to orbit under its own power. An advantage of such a system over single-stage-to-orbit is that the most of the dry mass of the vehicle is not carried into orbit. This reduces the cost involved in reaching orbital velocity, as much of the structure and engine mass is ejected, and a larger percentage of the orbited mass is payload mass. An advantage over three or more stages is a reduction in complexity and fewer separation events, which reduces cost and risk of failure.

Falcon 9 V1
Falcons () are birds of prey in the genus ''Falco'', which includes about 40 species. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene. Adult falcons have thin, tapered wings, which enable them to fly at high speed and change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a broad wing. This makes flying easier while learning the exceptional skills required to be effective hunters as adults. The falcons are the largest genus in the Falconinae subfamily of Falconidae, which itself also includes another subfamily comprising caracaras and a few other species. All these birds kill with their beaks, using a tomial "tooth" on the side of their beaks—unlike the hawks, eagles, and other birds of prey in the Accipitridae, which use their feet. The largest falcon ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Commercial Resupply Services
Commercial Resupply Services (CRS) are a series of flights awarded by NASA for the delivery of cargo and supplies to the International Space Station (ISS) on commercially operated spacecraft. The first CRS contracts were signed in 2008 and awarded $1.6 billion to SpaceX for twelve cargo Dragon and $1.9 billion to Orbital Sciences for eight Cygnus flights, covering deliveries to 2016. The Falcon 9 and Antares rockets were also developed under the CRS program to deliver cargo spacecraft to the ISS. The first operational resupply missions were flown by SpaceX in 2012 (SpaceX CRS-1) and Orbital Sciences in 2014 ( Cygnus CRS Orb-1). A second phase of contracts (known as CRS-2) was solicited in 2014. In 2015, NASA extended CRS-1 to twenty flights for SpaceX and twelve flights for Orbital ATK. CRS-2 contracts were awarded in January 2016 to Orbital ATK Cygnus, Sierra Nevada Corporation Dream Chaser, and SpaceX Dragon 2, for cargo transport flights beginning in 2019 and expected to ...

SpaceX CRS-2
SpaceX CRS-2, also known as SpX-2, was the fourth flight for SpaceX's uncrewed Dragon cargo spacecraft, the fifth and final flight for the company's two-stage Falcon 9 v1.0 launch vehicle, and the second SpaceX operational mission contracted to NASA under a Commercial Resupply Services (CRS-1) contract. The launch occurred on 1 March 2013. A minor technical issue on the Dragon spacecraft involving the RCS thruster pods occurred upon reaching orbit, but it was recoverable. The vehicle was released from the station on 26 March 2013, at 10:56 UTC and splashed down in the Pacific Ocean at 16:34 UTC. History The planned shipment of the Falcon 9 first stage from Texas to the Florida launch site was delayed due to the ongoing investigation of the engine failure that occurred on the previous flight. In late November 2012, it was reported that the CRS-2 Falcon 9 had been transported to Cape Canaveral (CCAFS). A static fire test occurred for the CRS-2 Falcon 9 on 25 February 2013. ...

New Product Development
In business and engineering, new product development (NPD) covers the complete process of bringing a new product (business), product to market, renewing an existing product or introducing a product in a new market. A central aspect of NPD is product design, along with various business considerations. New product development is described broadly as the transformation of a market opportunity into a product available for sale. The products developed by an organisation provide the means for it to generate income. For many technology-intensive firms their approach is based on exploiting technological innovation in a rapidly changing market. The product can be tangible (something physical which one can touch) or intangible (like a service or user experience, experience), though sometimes services and other processes are distinguished from "products". NPD requires an understanding of customer needs and wants, the competitive environment, and the nature of the market. Cost, time, and qua ...

Launch Vehicle
A launch vehicle or carrier rocket is a rocket designed to carry a payload (spacecraft or satellites) from the Earth's surface to outer space. Most launch vehicles operate from a launch pad, launch pads, supported by a missile launch control center, launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to large operating costs. An orbital spaceflight, orbital launch vehicle must lift its payload at least to the boundary of space, approximately and accelerate it to a horizontal velocity of at least . Suborbital spaceflight, Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles are multistage rockets which use chemical propellants such as Solid-propellant rocket, solid fuel, liquid hydrogen, kerosene, liquid oxygen, or Hypergolic propellants. Launch vehicles are cla ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Orbital Spaceflight
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth, it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around ; this is the boundary of space as defined by NASA, the US Air Force and the FAA. To remain in orbit at this altitude requires an orbital speed of ~7.8 km/s. Orbital speed is slower for higher orbits, but attaining them requires greater delta-v. The Fédération Aéronautique Internationale has established the Kármán line at an altitude of as a working definition for the boundary between aeronautics and astronautics. This is used because at an altitude of about , as Theodore von Kármán calculated, a vehicle would have to travel faster than orbital velocity to derive sufficient aerodynamic lift from the atmosphere to support itself. Due to atmospheric drag, the lowest altitude ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Merlin 1D Vacuum
Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9 and Falcon Heavy launch vehicles. Merlin engines use RP-1 and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea recovery and reuse, but since 2016 the entire Falcon 9 booster is recovered for reuse by landing vertically on a landing pad using one of its nine Merlin engines. The injector at the heart of Merlin is of the pintle type that was first used in the Apollo Lunar Module landing engine ( LMDE). Propellants are fed by a single-shaft, dual-impeller turbopump. The turbopump also provides high-pressure fluid for the hydraulic actuators, which then recycles into the low-pressure inlet. This eliminates the need for a separate hydraulic drive system and means that thrust vectoring control failure by running out of hydraulic fluid is not possible.
