Electrical System Of The International Space Station
The electrical system of the International Space Station is a critical resource for the International Space Station (ISS) because it allows the crew to live comfortably, to safely operate the station, and to perform scientific experiments. The ISS electrical system uses solar cells to directly convert sunlight to electricity. Large numbers of cells are assembled in arrays to produce high power levels. This method of harnessing solar power is called photovoltaics. The process of collecting sunlight, converting it to electricity, and managing and distributing this electricity builds up excess heat that can damage spacecraft equipment. This heat must be eliminated for reliable operation of the space station in orbit. The ISS power system uses radiators to dissipate the heat away from the spacecraft. The radiators are shaded from sunlight and aligned toward the cold void of deep space. Solar array wing Each ISS solar array wing (often abbreviated "SAW") consists of two retr ...

Earth Horizon And International Space Station Solar Panel Array (Expedition 17 Crew, August 2008)
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar energy is r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-117
STS-117 ( ISS assembly flight 13A) was a Space Shuttle mission flown by Space Shuttle ''Atlantis'', launched from pad 39A of the Kennedy Space Center on 8 June 2007. ''Atlantis'' lifted off from the launch pad at 19:38 EDT. Damage from a hail storm on 26 February 2007 had previously caused the launch to be postponed from an originally-planned launch date of 15 March 2007. The launch of STS-117 marked the 250th orbital human spaceflight. ''Atlantis'' delivered to the International Space Station (ISS) the second starboard truss segment (the S3/S4 Truss) and its associated energy systems, including a set of solar arrays. During the course of the mission the crew installed the new truss segment, retracted one set of solar arrays, and unfolded the new set on the starboard side of the station. STS-117 also brought Expedition 15 crewmember Clayton Anderson to the station, and returned with ISS crewmember Sunita Williams. On 11 June 2007, NASA mission managers announced a two-day ...

The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust Limited, Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISS New IROSA Deployed
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Expedition 65
Expedition 65 was the 65th long duration expedition to the International Space Station. The mission began on 17 April 2021, with the departure of Soyuz MS-17, and was initially commanded by NASA astronaut Shannon Walker serving as the third female ISS commander, who launched in November 2020 aboard SpaceX Crew-1 alongside NASA astronauts Michael S. Hopkins and Victor J. Glover, as well as JAXA astronaut Soichi Noguchi. They were joined by the crew of Soyuz MS-18, which is made up of Russian cosmonauts Oleg Novitsky and Pyotr Dubrov, as well as NASA astronaut Mark Vande Hei. In accordance with Crew Dragon ''Resilience'''s departure on May 2, 2021, Crew-1's crew was replaced by the crew of SpaceX Crew-2, which launched on April 23, 2021. JAXA astronaut Akihiko Hoshide took Walker's place as station commander, making Walker the shortest-serving ISS commander - holding the position for just 11 days. From October 4, 2021 ESA astronaut Thomas Pesquet surpassed Hoshide as command ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Expedition 64
Expedition 64 was the 64th long-duration expedition to the International Space Station (ISS), that began on 21 October 2020 with the undocking and departure of Soyuz MS-16. The Expedition started with the three crew members launched onboard Soyuz MS-17 and reached its full complement with the arrival of SpaceX Crew-1, the first operational flight of NASA's Commercial Crew Program (CCP). As Crew-1 consists of a crew of four instead of three like the Soyuz, Expedition 64 marks the beginning of operations for crews of seven on the ISS. In the final week of the mission, Soyuz MS-18 and its three cosmonaut crew joined the mission. The expedition ended on 17 April 2021 with the departure of Soyuz MS-17. Crew Extravehicular activity Several spacewalks for Expedition 63 were planned to carry out work on the scientific and power systems on the ISS. Delays to the NASA Commercial Crew Program left Chris Cassidy as the only crew member on the US Orbital Segment (USOS) for an extended ...

SpaceX CRS-28
SpaceX CRS-28, also known as SpX-28, is a Commercial Resupply Service mission to the International Space Station (ISS) scheduled to be launched in January 2023. The mission is contracted by NASA and will be flown by SpaceX using a Cargo Dragon. This will be the seventh flight for SpaceX under NASA's CRS Phase 2. Cargo Dragon SpaceX plans to reuse the Cargo Dragons up to five times. The Cargo Dragon will launch without SuperDraco abort engines, without seats, cockpit controls and the life support system required to sustain astronauts in space. Dragon 2 improves on Dragon 1 in several ways, including lessened refurbishment time, leading to shorter periods between flights. The new Cargo Dragon capsules under the NASA CRS Phase 2 contract will land east of Florida in the Atlantic Ocean. Payload NASA contracted for the CRS-28 mission from SpaceX and therefore determines the primary payload, date of launch, and orbital parameters for the Cargo Dragon. ISS Roll Out So ...
