Launch Status Check
A launch status check, also known as a "go/no go poll" and several other terms occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed. For Space Shuttle missions, in the firing room at the Launch Control Center, the NASA Test Director (NTD) performed this check via a voice communications link with other NASA personnel. The NTD was the leader of the shuttle test team responsible for directing and integrating all flight crew, orbiter, external tank/solid rocket booster and ground support testing in the shuttle launch countdown. The NTD was also responsible for the safety of all personnel inside the pad after external tank loading, including the flight crew, about 10 go/no go reports. He reported to the Launch Director, who has another about 5 go/no go reports. The Launch director declares if a mission is go for launch. Checklist of firing room posit ...

Flight Controller
Flight controllers are personnel who aid space flight by working in such Mission Control Centers as NASA's Mission Control Center or ESA's European Space Operations Centre. Flight controllers work at computer consoles and use telemetry to monitor various technical aspects of a space mission in real time. Each controller is an expert in a specific area and constantly communicates with additional experts in the "back room". The flight director, who leads the flight controllers, monitors the activities of a team of flight controllers, and has overall responsibility for success and safety. This article primarily discusses NASA's flight controllers at the Johnson Space Center (JSC) in Houston. The various national and commercial flight control facilities have their own teams, which may be described on their own pages. NASA's flight controllers The room where the flight controllers work was called the mission operations control room (MOCR, pronounced "moh-ker"), and now is calle ...

Space Launch
Space launch is the earliest part of a flight that reaches space. Space launch involves liftoff, when a rocket or other space launch vehicle leaves the ground, floating ship or midair aircraft at the start of a flight. Liftoff is of two main types: rocket launch (the current conventional method), and non-rocket spacelaunch (where other forms of propulsion are employed, including airbreathing jet engines or other kinds). Issues with reaching space Definition of outer space Energy Therefore, by definition for spaceflight to occur, sufficient altitude is necessary. This implies a minimum gravitational potential energy needs to be overcome: for the Kármán line this is approximately 1 MJ/kg. W=mgh, m=1 kg, g=9.82 m/s2, h=105m. W=1*9.82*105≈106J/kg=1MJ/kg In practice, a higher energy than this is needed to be expended due to losses such as airdrag, propulsive efficiency, cycle efficiency of engines that are employed and gravity drag. In the past fifty years spacefl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-114
STS-114 was the first "Return to Flight" Space Shuttle mission following the Space Shuttle Columbia disaster, Space Shuttle ''Columbia'' disaster. Space Shuttle Discovery, ''Discovery'' launched at 10:39 Eastern Time Zone, EDT (14:39 Coordinated Universal Time, UTC), July 26, 2005. The launch, 907 days (approx. 29 months) after the loss of ''Columbia'', was approved despite unresolved fuel sensor anomalies in the Space Shuttle external tank, external tank that had prevented the shuttle from launching on July 13, its originally scheduled date. The mission ended on August 9, 2005, when ''Discovery'' landed at Edwards Air Force Base in California. Poor weather over the Kennedy Space Center in Florida hampered the shuttle from using its primary landing site. Analysis of the launch footage showed debris separating from the external tank during ascent; this was of particular concern because it was the issue that had set off the ''Columbia'' disaster. As a result, NASA decided on July ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-115
STS-115 was a Space Shuttle mission to the International Space Station (ISS) flown by . It was the first assembly mission to the ISS after the ''Columbia'' disaster, following the two successful ''Return to Flight'' missions, STS-114 and STS-121. STS-115 launched from LC-39B at the Kennedy Space Center on 9 September 2006 at 11:14:55 EDT (15:14:55 UTC). The mission is also referred to as ISS-12A by the ISS program. The mission delivered the second port-side truss segment (ITS P3/P4), a pair of solar arrays (2A and 4A), and batteries. A total of three spacewalks were performed, during which the crew connected the systems on the installed trusses, prepared them for deployment, and did other maintenance work on the station. STS-115 was originally scheduled to launch in April 2003. The ''Columbia'' accident in February 2003 pushed the date back to 27 August 2006, which was again moved back for various reasons, including a threat from Tropical Storm Ernesto and the strongest l ...

STS-122
STS-122 was a NASA Space Shuttle mission to the International Space Station (ISS), flown by the . STS-122 marked the 24th shuttle mission to the ISS, and the 121st Space Shuttle flight overall. The mission was also referred to as ISS-1E by the ISS program. The primary objective of STS-122 was to deliver the European ''Columbus'' science laboratory, built by the European Space Agency (ESA), to the station. It also returned Expedition 16 Flight Engineer Daniel M. Tani to Earth. Tani was replaced on Expedition 16 by Léopold Eyharts, a French Flight Engineer representing ESA. After ''Atlantis'' landing, the orbiter was prepared for STS-125, the final servicing mission for the Hubble Space Telescope. The original target launch date for STS-122 was 6 December 2007, but due to engine cutoff sensor (ECO) reading errors, the launch was postponed to 9 December 2007. During the second launch attempt, the sensors failed again, and the launch was halted. A tanking test on 18 December 2007 r ...

STS-123
STS-123 was a Space Shuttle mission to the International Space Station (ISS) which was flown by Space Shuttle ''Endeavour''. STS-123 was the 1J/A ISS assembly mission. The original launch target date was 14 February 2008 but after the delay of STS-122, the shuttle was launched on 11 March 2008. It was the twenty-fifth shuttle mission to visit the ISS, and delivered the first module of the Japanese laboratory, Japanese Experiment Module (''Kibō''), and the Canadian Special Purpose Dexterous Manipulator, (SPDM) Dextre robotics system to the station. The mission duration was 15 days and 18 hours, and it was the first mission to fully utilize the Station-to-Shuttle Power Transfer System (SSPTS), allowing space station power to augment the shuttle power systems. The mission set a record for a shuttle's longest stay at the ISS. Crew Mission payloads STS-123 delivered the pressurized section of the Japanese Experiment Logistics Module (ELM-PS) as well as the Special Purpose D ...

Spacecraft Propulsion
Spacecraft propulsion is any method used to accelerate spacecraft and artificial satellites. In-space propulsion exclusively deals with propulsion systems used in the vacuum of space and should not be confused with space launch or atmospheric entry. Several methods of pragmatic spacecraft propulsion have been developed each having its own drawbacks and advantages. Most satellites have simple reliable chemical thrusters (often monopropellant rockets) or resistojet rockets for orbital station-keeping and some use momentum wheels for attitude control. Soviet bloc satellites have used electric propulsion for decades, and newer Western geo-orbiting spacecraft are starting to use them for north–south station-keeping and orbit raising. Interplanetary vehicles mostly use chemical rockets as well, although a few have used ion thrusters and Hall-effect thrusters (two different types of electric propulsion) to great success. Hypothetical in-space propulsion technologies describe the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Space Exploration
Space exploration is the use of astronomy and space technology to explore outer space. While the exploration of space is carried out mainly by astronomers with telescopes, its physical exploration though is conducted both by robotic spacecraft, uncrewed robotic space probes and human spaceflight. Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy, predates reliable recorded history, it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to become a reality. The world's first large-scale experimental rocket program was Opel-RAK under the leadership of Fritz von Opel and Max Valier during the late 1920s leading to the first crewed rocket cars and rocket planes, which paved the way for the Nazi era V2 program and US and Soviet activities from 1950 onwards. The Opel-RAK program and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timeline Of Spaceflight
This is the timeline of known spaceflights, both crewed and uncrewed, sorted chronologically by launch date. Owing to its large size, the timeline is split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951. The list, and lists for subsequent years, contain planned launches, though clicking on in the infobox (at right) will show you to this year's actuals-to- For the purpose of these lists, a spaceflight is defined as any flight that crosses the Kármán line, the Fédération Aéronautique Internationale, FAI-recognized edge of space, which is Above mean sea level, above mean sea level (AMSL). The timeline contains all flights which have crossed the edge of space, were intended to do so but failed, or are planned in the near future. Significant test flights of spaceflight systems may be listed even if they were not planned to reach space. Some lists are further divided into orbital launches (sending a p ...

List Of Human Spaceflights
This is a list of all human spaceflights throughout history. Beginning in 1961 with the flight of Yuri Gagarin aboard Vostok 1, human spaceflight occurs when a human crew flies a spacecraft into outer space. Human spaceflight is distinguished from spaceflight generally, which entails both crewed and uncrewed spacecraft. There are two definitions of spaceflight. The Fédération Aéronautique Internationale (FAI), an international record-keeping body, defines the boundary between Earth's atmosphere and outer space at above sea level. This boundary is known as the Kármán line. Additionally, the United States awards astronaut wings to qualified personnel who pilot a spaceflight above an altitude of . As of the launch of Shenzhou 15 on 29 November 2022, there have been 367 human spaceflight launches. Two missions did not cross either the Kármán line or the U.S. definition of space and therefore do not qualify as spaceflights. These were the fatal STS-51-L (Challenger disas ...
