Dragon 2
Dragon 2 is a class of partially reusable spacecraft developed, manufactured, and operated by the American space company SpaceX for flights to the International Space Station (ISS) and private spaceflight missions. The spacecraft, which consists of a reusable space capsule and an expendable trunk module, has two variants: the 4-person Crew Dragon and Cargo Dragon, a replacement for the Dragon 1 cargo capsule. The spacecraft launches atop a Falcon 9 Block 5 rocket, and the capsule returns to Earth through splashdown. Crew Dragon's primary role is to transport crews to and from the ISS under NASA's Commercial Crew Program, a task handled by the Space Shuttle until it was retired in 2011. It will be joined by Boeing's Starliner in this role when NASA certifies it. Crew Dragon is also used for commercial flights to ISS and other destinations and is expected to be used to transport people to and from Axiom Space's planned space station. Cargo Dragon brings cargo to the ISS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Capsule
A space capsule is a spacecraft designed to transport cargo, scientific experiments, and/or astronauts to and from space. Capsules are distinguished from other spacecraft by the ability to survive reentry and return a payload to the Earth's surface from orbit or sub-orbit, and are distinguished from other types of recoverable spacecraft by their blunt shape, not having wings and often containing little fuel other than what is necessary for a safe return. Capsule-based human spaceflight, crewed spacecraft such as Soyuz (spacecraft), Soyuz or Orion (spacecraft), Orion are often supported by a service or adapter module, and sometimes augmented with an extra module for extended space operations. Capsules make up the majority of crewed spacecraft designs, although one crewed spaceplane, the Space Shuttle, has flown in orbit. Current examples of crewed space capsules include Soyuz spacecraft, Soyuz, Shenzhou spacecraft, Shenzhou, and SpaceX Dragon 2, Dragon 2. Examples of new crew capsu ...

Ablative Heat Shield
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 l ... [...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 phase of CRS contracts (CRS-1) were signed in 2008 and awarded $1.6 billion to SpaceX for twelve SpaceX Dragon 1, Dragon 1 and $1.9 billion to Orbital Sciences for eight Cygnus (spacecraft), Cygnus flights, covering deliveries to 2016. The first operational resupply missions were flown by SpaceX in 2012 (SpaceX CRS-1, CRS SpX-1) and Orbital in 2014 (Cygnus CRS Orb-1, CRS Orb-1). In 2015, NASA extended CRS-1 to twenty flights for SpaceX and twelve flights for Orbital ATK. A second phase of contracts (CRS-2) was solicited in 2014. CRS-2 contracts were awarded in January 2016 to Orbital ATK's continued use of Cygnus (spacecraft), Cygnus, Sierra Nevada Corporation's new Dream Chaser, and SpaceX's new SpaceX Dragon 2, Dragon 2, for cargo transport flights beginning in 2019 and expec ...

Space Logistics
Space logistics is "the theory and practice of driving space system design for operability and supportability, and of managing the flow of materiel, services, and information needed throughout a space system lifecycle." It includes terrestrial logistics in support of space travel, including any additional "design and development, acquisition, storage, movement, distribution, maintenance, evacuation, and disposition of space materiel", movement of people in space (both routine and for medical and other emergencies), and contracting and supplying any required support services for maintaining space travel. The space logistics research and practice primarily focus on the modeling and management of the astro-logistics supply chain from Earth and on to destinations throughout the Solar System as well as the system architecture strategies to minimize both logistics requirements and operational costs of human and robotic operations in space. History As early as 1960, Wernher von Braun s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axiom Orbital Segment
Axiom Station is a planned modular space station designed by Houston, Texas-based Axiom Space for commercial space activities. Axiom Space gained initial NASA approval for the venture in January 2020. Axiom Space was later awarded the contract by NASA on February 28, 2020. Axiom Station is one of multiple Commercial LEO Destinations (CLD) projects supported by NASA to build a successor to the International Space Station (ISS) before its decommissioning in 2030. Axiom Segment Between 2020 and 2024, Axiom Space intended to assemble four modules in a dedicated segment docked to the ISS before detaching them to form the free-flying Axiom Station. Axiom renderings illustrate how the four modules might attach to the ISS as they are berthed and relocated by the Mobile Servicing System using the robotic arm Canadarm2. The company released preliminary plans in February 2020 for how the Axiom Orbital Segment could form the basis for the Axiom Station, constructed out of the Axi ...

Retirement Of The Space Shuttle
The retirement of NASA's Space Shuttle fleet took place from March to July 2011. ''Discovery'' was the first of the three active Space Shuttles to be retired, completing its final mission on March 9, 2011; '' Endeavour'' did so on June 1. The final shuttle mission was completed with the landing of ''Atlantis'' on July 21, 2011, closing the 30-year Space Shuttle program. The Shuttle was presented to the public in 1972 as a "space truck" which would, among other things, be used to build a United States space station in low Earth orbit in the early 1990s and then be replaced by a new vehicle. When the concept of the U.S. space station evolved into that of the International Space Station, which suffered from long delays and design changes before it could be completed, the service life of the Space Shuttle fleet was extended several times until 2011 when it was finally retired. After the ''Columbia'' loss in 2003, the ''Columbia'' Accident Investigation Board report showed that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
