Public Health And Social Welfare
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the ''Öffentlichkeit'' or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, and suffered more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder. Etymology and definitions The name "public" originates with the Latin ''publicus'' (also '' poplicus''), from ''populus'', to the English word 'populace', and in general denotes some mass population ("the ...

Private Sector
The private sector is the part of the economy, sometimes referred to as the citizen sector, which is owned by private groups, usually as a means of establishment for profit or non profit, rather than being owned by the government. Employment The private sector employs most of the workforce in some countries. In private sector, activities are guided by the motive to earn money. A 2013 study by the International Finance Corporation (part of the World Bank Group) identified that 90 percent of jobs in developing countries are in the private sector. Diversification In free enterprise countries, such as the United States, the private sector is wider, and the state places fewer constraints on firms. In countries with more government authority, such as China, the public sector makes up most of the economy. Regulation States legally regulate the private sector. Businesses operating within a country must comply with the laws in that country. In some cases, usually involving multinatio ...

NASA Authorization Act Of 2010
The NASA Authorization Act of 2010 is a U.S. law authorizing NASA appropriations for fiscal years 2011, 2012, 2013 with the same top-line budget values as requested by US President Barack Obama. It resulted from the Augustine Commission's review of then-current crewed space flight plans. The law supports an overall growth in science, aeronautics, and space technology and defines a long-term goal for human spaceflight to expand a permanent human presence beyond low Earth orbit. Key objectives of this goal include full utilization of the International Space Station (ISS), determining the ability of humans to live in outer space for extended periods of time, maximizing the role of space exploration and space technology in current and future missions, advancing knowledge and inspiring young people into higher education, and building upon international partnerships. The act was signed by President Obama on October 11, 2010. A total of $58 billion in funding is called for, spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA Budget
As a federal agency, the National Aeronautics and Space Administration (NASA) receives its funding from the annual federal budget passed by the United States Congress. The following charts detail the amount of federal funding allotted to NASA each year over its history to pursue programs in aeronautics research, robotic spaceflight, technology development, and human space exploration programs. Annual budget NASA's budget for financial year (FY) 2020 is $22.6 billion. It represents 0.48% of the $4.7 trillion the United States plans to spend in the fiscal year.

Hubble Space Telescope
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detaile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-125
STS-125, or HST-SM4 (Hubble Space Telescope Servicing Mission 4), was the fifth and final Space Shuttle mission to the Hubble Space Telescope (HST) and the last solo flight of the Space Shuttle Atlantis, Space Shuttle ''Atlantis''. The launch of the Space Shuttle ''Atlantis'' occurred on 11 May 2009 at 2:01 pm EDT.

Magnetospheric Multiscale Mission
The Magnetospheric Multiscale (MMS) Mission is a NASA robotic space mission to study the Earth's magnetosphere, using four identical spacecraft flying in a tetrahedral formation. The spacecraft were launched on 13 March 2015 at 02:44 UTC. The mission is designed to gather information about the microphysics of magnetic reconnection, energetic particle acceleration, and turbulence — processes that occur in many astrophysical plasmas. As of March 2020, the MMS spacecraft have enough fuel to remain operational until 2040. Background The mission builds upon the successes of the ESA Cluster mission, but will surpass it in spatial resolution and in temporal resolution, allowing for the first time measurements of the critical electron diffusion region, the site where magnetic reconnection occurs. Its orbit is optimized to spend extended periods in locations where reconnection is known to occur: at the dayside magnetopause, the place where the pressure from the solar wind an ...

International Space Station
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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crew Exploration Vehicle
The Crew Exploration Vehicle (CEV) was a component of the U.S. NASA Vision for Space Exploration plan. A competition was held to design a spacecraft that could carry humans to the destinations envisioned by the plan. The winning design was the Orion spacecraft. Although it was originally conceived during the Space Exploration Initiative during the 90s, official planning for the vehicle began in 2004, with the final Request For Proposal issued on March 1, 2005, to begin a design competition for the vehicle. For the later design and construction phases, see Orion (spacecraft). The Orion CEV became part of NASA's Constellation Program to send human explorers back to the Moon, and then onward to Mars and other destinations in the Solar System. After Constellation was cancelled, it was envisioned for emergency evacuation of the International Space Station, then retained for revived Solar System exploration plans. Competition The concept for the vehicle was officially announce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Reconnaissance Orbiter
The Lunar Reconnaissance Orbiter (LRO) is a NASA robotic spacecraft currently orbiting the Moon in an eccentric polar mapping orbit. Data collected by LRO have been described as essential for planning NASA's future human and robotic missions to the Moon. Its detailed mapping program is identifying safe landing sites, locating potential resources on the Moon, characterizing the radiation environment, and demonstrating new technologies. Launched on June 18, 2009, in conjunction with the Lunar Crater Observation and Sensing Satellite (LCROSS), as the vanguard of NASA's Lunar Precursor Robotic Program, LRO was the first United States mission to the Moon in over ten years. LRO and LCROSS were launched as part of the United States's Vision for Space Exploration program.
