The National Aeronautics and Space Administration (NASA) is the agency of the United States Federal Government responsible for the civilian space program as well as aeronautics and aerospace research.

President Dwight D. Eisenhower established the National Aeronautics and Space Administration (NASA) in 1958 with a distinctly civilian (rather than military) orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29, 1958, disestablishing NASA's predecessor, the National Advisory Committee for Aeronautics (NACA). The new agency became operational on October 1, 1958.

Since that time, most US space exploration efforts have been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the Space Launch System and Commercial Crew vehicles. The agency is also responsible for the Launch Services Program (LSP) which provides oversight of launch operations and countdown management for unmanned NASA launches.

Falcon (rocket family)

The Falcon rocket family is an American family of multi-use rocket launch vehicles developed and operated by Space Exploration Technologies (SpaceX). They are the first orbital launch vehicles to be entirely designed in the 21st century.

The vehicles in this family include the flight-tested Falcon 1 and Falcon 9. The Falcon 1 made its first successful flight on 28 September 2008, after several failures on the initial attempts. The larger Evolved Expendable Launch Vehicle (EELV)-class Falcon 9 flew successfully into orbit on its maiden launch on 4 June 2010. The Falcon 9 is eventually intended to be a reusable vehicle. SpaceX is currently in production of the first Falcon Heavy launch system. Other designs for boosters with even larger payload lifting capabilities are currently being researched, but not yet confirmed.

Naming

Elon Musk, CEO of SpaceX, has stated that the Falcon rockets are named after the Millennium Falcon from the Star Wars film series.

Current launch vehicles

Falcon 9

Falcon 9 is a family of two-stage-to-orbit launch vehicles, named for its use of nine engines, designed and manufactured by SpaceX. The Falcon 9 versions are the Falcon 9 v1.0 (retired), Falcon 9 v1.1 (retired), and the current Falcon 9 full thrust, a partially-reusable launch system. Both stages are powered by rocket engines that burn liquid oxygen (LOX) and rocket-grade kerosene (RP-1) propellants. The first stage is designed to be reusable, while the second stage is not reusable. The three Falcon 9 versions are in the medium-lift range of launch systems. The current Falcon 9 ("full thrust upgrade") can lift payloads of at least 13,150 kilograms (28,990 lb) to low Earth orbit, and at least 5,300 kilograms (11,700 lb) to geostationary transfer orbit. Full payload capacity is kept private, and may vary depending on whether the first stage follows a reusable or expendable flight profile.

The Falcon 9 and Dragon capsule combination won a Commercial Resupply Services (CRS) contract from NASA in 2008 to deliver cargo to the International Space Station (ISS) under the Commercial Orbital Transportation Services (COTS) program. The first commercial resupply mission to the ISS launched in October 2012. The initial version 1.0 design made five flights before it was retired in 2013. The version 1.1 design made a total of 15 flights beginning in 2013 before it was retired in January 2016.

Post-office box

A post-office box or post office box (commonly referred to as a PO box or a postal box) is a uniquely addressable lockable box located on the premises of a post office station.

In many regions, particularly in Africa and the Middle East, there is no 'door to door' delivery of mail. For example, should one post mail to a street address in Namibia, it will be returned to sender as undeliverable. Consequently, renting a PO box has traditionally been the only way to receive mail in such countries, although some, like Jordan, Egypt and Lebanon, do have mail home delivery.

Generally, post office boxes are rented from the post office either by individuals or by businesses on a basis ranging from monthly to annual, and the cost of rent varies depending on the box size. Central business district (CBD) PO boxes are usually more expensive than rural PO boxes.

In the United States, the rental rate used to be uniform across the country. Now, however, a postal facility can be in any of seven fee groups by location; in addition, certain customers qualify for free box rental.

The Daily Show

The Daily Show (also known as The Daily Show with Jon Stewart from 1999 until 2015, and The Daily Show with Trevor Noah as of 2015) is an American late-night talk and news satire television program, which airs each Monday through Thursday on Comedy Central and, in Canada, The Comedy Network.

The half-hour-long show premiered on July 21, 1996, and was hosted by Craig Kilborn until December 17, 1998. Jon Stewart then took over as the host from January 11, 1999 until August 6, 2015, making the show more strongly focused on politics and the national media, in contrast with the pop culture focus during Kilborn's tenure. Stewart was succeeded by Trevor Noah, whose tenure premiered on September 28, 2015. The Daily Show is the longest-running program on Comedy Central (counting all three tenures), and has won 22 Primetime Emmy Awards.

Describing itself as a fake news program, The Daily Show draws its comedy and satire from recent news stories, political figures, media organizations, and often aspects of the show itself. During Stewart's tenure, the show typically opened with a long monologue, relating to recent headlines and frequently featured exchanges with one or more of several correspondents, who adopted absurd or humorously exaggerated takes on current events against Stewart's straight man persona. The final segment was devoted to a celebrity interview, with guests ranging from actors and musicians to nonfiction authors and political figures.
