Spacex Crs-11
SpaceX CRS-11, also known as SpX-11, was a Commercial Resupply Service mission to the International Space Station, launched successfully on 3 June 2017. The mission was contracted by NASA and was flown by SpaceX. The mission utilized a Falcon 9 launch vehicle and was the first reuse of C106, a CRS Dragon cargo vessel that was previously flown on the CRS-4 mission. CRS-11 was the penultimate of the first twelve missions awarded to SpaceX under the Commercial Resupply Services contract to resupply the International Space Station. Rocket and spacecraft The CRS-11 mission was the first time that a Dragon spacecraft has been reused, helping SpaceX to scale back its production line and shift focus to Dragon 2. CRS-11 launched aboard a Falcon 9 launch vehicle on 3 June 2017 at 21:07:38 UTC from Kennedy Space Center's Launch Complex 39A (LC-39A).

SpaceX Dragon C106
SpaceX Dragon C106 is a Dragon space capsule built by SpaceX. It is the first reused SpaceX Dragon capsule to be reflown into space, having its second launch in 2017. C106 was first used on CRS-4, and then used again for the CRS-11 and CRS-19 missions. It was the second capsule after C108 to be used a third time, marking a milestone in SpaceX's drive to reduce space launch costs through reusing hardware. History C106 was built as the sixth production Dragon capsule. This new Dragon was launched in September 2014 for the CRS-4 mission to the International Space Station (ISS). It splashed down in October 2014, and was successfully retrieved. To prepare for its second flight, it had its heatshield replaced while the hull, avionics, and Draco thrusters were refurbished. The refurbished Dragon was relaunched in June 2017 for the CRS-11 mission to the ISS. It splashed down and was successfully recovered in July 2017. After undergoing another refurbishment, C106 was launched ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cygnus OA-7
OA-7, previously known as Orbital-7, is the eighth flight of the Orbital ATK uncrewed resupply spacecraft Cygnus and its seventh flight to the International Space Station (ISS) under the Commercial Resupply Services contract with NASA. The mission launched on 18 April 2017 at 15:11:26 UTC.

Orbital Elements
Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit. There are many different ways to mathematically describe the same orbit, but certain schemes, each consisting of a set of six parameters, are commonly used in astronomy and orbital mechanics. A real orbit and its elements change over time due to gravitational perturbations by other objects and the effects of general relativity. A Kepler orbit is an idealized, mathematical approximation of the orbit at a particular time. Keplerian elements The traditional orbital elements are the six Keplerian elements, after Johannes Kepler and his laws of planetary motion. When viewed from an inertial frame, two orbiting bodies trace out distinct trajectories. Each of these trajectories has its focus at the common center of mass. When viewed from a non-inertial frame centered on one of the bodies, only the traj ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guidance, Navigation, And Control
Guidance, navigation and control (abbreviated GNC, GN&C, or G&C and within the context of NASA operations, often pronounced 'Gintsee' or (IPA) ʤɪnsiː) is a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. In many cases these functions can be performed by trained humans. However, because of the speed of, for example, a rocket's dynamics, human reaction time is too slow to control this movement. Therefore, systems—now almost exclusively digital electronic—are used for such control. Even in cases where humans can perform these functions, it is often the case that GNC systems provide benefits such as alleviating operator work load, smoothing turbulence, fuel savings, etc. In addition, sophisticated applications of GNC enable automatic or remote control. * '' Guidance'' refers to the determination of the desired path of travel (the "trajectory") from the vehicle's curr ...

Landing Zone 1
Landing Zone 1 and Landing Zone 2, also known as LZ-1 and LZ-2 respectively, are landing facilities on Cape Canaveral Space Force Station for recovering components of SpaceX's VTVL reusable launch vehicles. LZ-1 and LZ-2 were built on land leased in February 2015, on the site of the former Cape Canaveral Launch Complex 13. SpaceX built Landing Zone 2 at the facility to have a second landing pad, allowing two Falcon Heavy boosters to land simultaneously. Site Landing Zones 1 and 2 are located at the former location of Launch Complex 13, which has been demolished and replaced by two circular landing pads in diameter and marked with a stylized ''X'' from the SpaceX company logo. Four more diameter pads were initially planned to be built to support the simultaneous recovery of additional boosters used by the Falcon Heavy, although only one extra pad has been built. Planned infrastructure additions to support operations includes improved roadways for crane movement, a rocket ped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
