2020s In Spaceflight
This article documents expected notable spaceflight events during the 2020s. Overview The trend towards cost reduction in access to orbit is expected to continue. In 2022, SpaceX plans to launch its new fully reusable Starship to orbit and Vulcan is planned to replace its more expensive predecessors. Ariane 6 is expected to replace the more expensive Ariane 5 in 2023, and Blue Origin plans to launch the maiden flight of New Glenn with a reusable first stage in early 2023. Mars stays a focus for missions to other planets, with three missions launched in 2020 (by China, the United Arab Emirates and the United States) and at least two missions planned for 2024 (India and Japan). In 2028, as part of the NASA-ESA Mars Sample Return mission, NASA plans to launch a Sample Retrieval Lander. In 2027, ESA plans to launch the Earth Return Orbiter, which will transport the retrieved samples from Mars to Earth by 2033. China is also planning to retrieve samples from Mars by 2031 ...

Lunar Gateway
The Lunar Gateway, or simply Gateway, is the first planned extraterrestrial space station in lunar orbit intended to serve as a solar-powered communication hub, science laboratory, and short-term habitation module for government-agency astronauts, as well as a holding area for rovers and other robots. It is a multinational collaborative project involving four of the International Space Station partner agencies: NASA, European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA), and Canadian Space Agency (CSA). It is planned to be both the first space station beyond low Earth orbit and the first space station to orbit the Moon. Formerly known as the Deep Space Gateway (DSG), the station was renamed Lunar Orbital Platform-Gateway (LOP-G) in NASA's 2018 proposal for the 2019 United States federal budget. When the budgeting process was complete, US$332 million had been committed by Congress to preliminary studies. The science disciplines to be studied on the Gatew ...

Mars Orbiter Mission 2
Mars Orbiter Mission 2 (MOM 2), also called ''Mangalyaan-2'' ("Mars-craft", from sa, मंगल ''mangal'', "Mars" and यान ''yān'', "craft, vehicle"), is India's second interplanetary mission planned by the Indian Space Research Organisation (ISRO). In a recorded interview in October 2019, Vikram Sarabhai Space Centre (VSSC) director indicated possibility of inclusion of a lander but in an interview to The Times Of India in February 2021 ISRO chairman clarified that the mission will consist only an orbiter. The orbiter will use aerobraking to lower its initial apoapsis and enter into an orbit more suitable for observations. The Indian Space Research Organization plans to launch this mission by 2025. The mission will include a hyperspectral camera, a high resolution panchromatic camera and a radar to understand early Martian crust, recent basalts and boulder falls. The mission is proposed to be followed by another, including soft landing on Mars in 2030. History Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Arab Emirates Space Agency
The United Arab Emirates Space Agency (UAESA) ( ar, وكالة الإمارات للفضاء translit: wikālat al-Imārāt l-lifaḍā') is the space agency of the United Arab Emirates government responsible for the development of the country's space industry. It was created in 2014 and is responsible for developing and regulating the space sector in the UAE. The agency is charged with the growth of the sector through partnerships, academic programmes and investments in R&D, commercial initiatives, and driving space science research and exploration. History The UAE proposed in 2008 to establish a Pan-Arab Space Agency, as a civilian project like the European Space Agency (ESA). The Arab Science and Technology Foundation said an agency for the Middle East and North Africa already had unofficial support from some governments and hoped that a regional organisation for disseminating satellite images could form an early foundation. The agency would monitor security and environment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "spac ...

Satellite Constellation
A satellite constellation is a group of artificial satellites working together as a system. Unlike a single satellite, a constellation can provide permanent global or near-global coverage, such that at any time everywhere on Earth at least one satellite is visible. Satellites are typically placed in sets of complementary orbital planes and connect to globally distributed ground stations. They may also use inter-satellite communication. Other satellite groups Satellite constellations should not be confused with: * ''satellite clusters'', which are groups of satellites moving very close together in almost identical orbits (see satellite formation flying); * '' satellite series'' or ''satellite programs'' (such as Landsat), which are generations of satellites launched in succession; * ''satellite fleets'', which are groups of satellites from the same manufacturer or operator that function independently from each other (not as a system).

Starlink
Starlink is a satellite internet constellation operated by SpaceX, providing satellite Internet access coverage to 45 countries. It also aims for global mobile phone service after 2023. SpaceX started launching Starlink satellites in 2019. As of December 2022, Starlink consists of over 3,300 mass-produced small satellites in low Earth orbit (LEO), which communicate with designated ground transceivers. In total, nearly 12,000 satellites are planned to be deployed, with a possible later extension to 42,000. SpaceX announced reaching more than one million subscribers in December 2022. The SpaceX satellite development facility in Redmond, Washington houses the Starlink research, development, manufacturing, and orbit control teams. The cost of the decade-long project to design, build, and deploy the constellation was estimated by SpaceX in May 2018 to be at least US$10 billion. SpaceX expects more than $30 billion in revenue by 2025 from its satellite constellation, while revenues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Small Satellites
A small satellite, miniaturized satellite, or smallsat is a satellite of low mass and size, usually under . While all such satellites can be referred to as "small", different classifications are used to categorize them based on mass. Satellites can be built small to reduce the large economic cost of launch vehicles and the costs associated with construction. Miniature satellites, especially in large numbers, may be more useful than fewer, larger ones for some purposes – for example, gathering of scientific data and radio relay. Technical challenges in the construction of small satellites may include the lack of sufficient power storage or of room for a propulsion system. Rationales One rationale for miniaturizing satellites is to reduce the cost; heavier satellites require larger rockets with greater thrust that also have greater cost to finance. In contrast, smaller and lighter satellites require smaller and cheaper launch vehicles and can sometimes be launched in multipl ...

Near-Earth Object
A near-Earth object (NEO) is any small Solar System body whose orbit brings it into proximity with Earth. By convention, a Solar System body is a NEO if its closest approach to the Sun (perihelion) is less than 1.3 astronomical units (AU). If a NEO's orbit crosses the Earth's orbit, and the object is larger than across, it is considered a potentially hazardous object (PHO). Most known PHOs and NEOs are asteroids, but a small fraction are comets. There are over 30,503 known near-Earth asteroids (NEAs) and over a hundred known short-period near-Earth comets (NECs). A number of solar-orbiting meteoroids were large enough to be tracked in space before striking the Earth. It is now widely accepted that collisions in the past have had a significant role in shaping the geological and biological history of the Earth. Asteroids as small as in diameter can cause significant damage to the local environment and human populations. Larger asteroids penetrate the atmosphere to the surf ...

NEO Surveyor
NEO Surveyor, formerly called Near-Earth Object Camera (NEOCam), then NEO Surveillance Mission, is a planned space-based infrared telescope designed to survey the Solar System for potentially hazardous asteroids. The NEO Surveyor spacecraft will survey from the Sun–Earth L1 (inner) Lagrange point, allowing it to look close to the Sun and see objects inside Earth's orbit. The mission will be a successor to the mission; the |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...
