Government procurement in the United States is the process by which the Federal Government of the United States acquires goods, services (notably construction), and interests in real property.
 In FY 2016 alone the US Federal Government spent $461B on contracts.
 Contracts for Government procurement usually involve appropriated funds spent on supplies, services, and interests in real property by and for the use of the Federal Government through purchase or lease, whether the supplies, services, or interests are already in existence or must be created, developed, demonstrated, and evaluated.
 "See" 48 C.F.R. § 2.101 ("Acquisition" defined, as to goods and services only).
 Federal Government contracting has the same legal elements as contracting between private parties: a lawful purpose, competent contracting parties, an offer, an acceptance that complies with the terms of the offer, mutuality of obligation, and consideration.
 However, Federal contracts are much more heavily regulated, subject to volumes of statutes dealing with Federal contracts and the Federal contracting process, mostly in Titles 10, 31, 40, and 41 of the United States Code.
Titan Lake In-situ Sampling Propelled Explorer (TALISE) is a proposed Spanish space probe that would splash-down in Ligeia Mare, the second largest lake on Saturn's moon Titan.
 TALISE would navigate across the lake for six months to one year.
Federal lands are lands in the United States for which ownership is claimed by the U.S. federal government, pursuant to of the United States Constitution.
 The United States Supreme Court has repeatedly held that this section empowers Congress to retain federal lands, to regulate federal lands such as by limiting cattle grazing, and to sell such lands.
 As of March 2012, out of the 2.27 billion acres (918.6 million hectares) in the country, about 28% of the total was owned by the Federal government according to the Interior Department.
 The United States Supreme Court has upheld the broad powers of the federal government to deal with federal lands, for example having unanimously held in "Kleppe v. New Mexico" that "the complete power that Congress has over federal lands under this clause necessarily includes the power to regulate and protect wildlife living there, state law notwithstanding."
Davita Vance-Cooks is the 27th Public Printer of the United States, the Chief Executive Officer of the U.S. Government Publishing Office (GPO).
 Vance-Cooks is a business executive with more than 30 years of private sector and federal government management experience.
 She is the first woman and first African-American to lead the agency, whose mission since its establishment in 1861 is to Keep America Informed.
 As the provider of official federal government information in digital and printed formats, the GPO produces the Congressional Record, the Federal Register, U.S. passports, and a wide variety of other publications.
 The agency provides free public access to government information products through federal depository libraries nationwide as well as free online access via GPO’s Federal Digital System.
The Federal Register, abbreviated FR or sometimes Fed.
 Reg., is the official journal of the federal government of the United States that contains government agency rules, proposed rules, and public notices.
 It is published daily, except on federal holidays.
 The final rules promulgated by a federal agency and published in the "Federal Register" are ultimately reorganized by topic or subject matter and codified in the "Code of Federal Regulations" (CFR), which is updated annually.
Titan Mare Explorer (TiME) is a proposed design for a lander for Saturn's moon Titan.
 TiME is a relatively low-cost, outer-planet mission designed to measure the organic constituents on Titan and would have performed the first nautical exploration of an extraterrestrial sea, analyze its nature and, possibly, observe its shoreline.
 As a Discovery-class mission it was designed to be cost-capped at US$425 million, not counting launch vehicle funding.
 It was proposed to NASA in 2009 by Proxemy Research as a scout-like pioneering mission, originally as part of NASA's Discovery Program.
 The TiME mission design reached the finalist stage during that Discovery mission selection, but was not selected, and despite attempts in the U.S. Senate failed to get earmark funding in 2013.
The Federal Works Agency (FWA) was an independent agency of the federal government of the United States which administered a number of public construction, building maintenance, and public works relief functions and laws from 1939 to 1949.
 Along with the Federal Security Agency and Federal Loan Agency, it was one of three catch-all agencies of the federal government pursuant to reorganization plans authorized by the Reorganization Act of 1939, the first major, planned reorganization of the executive branch of the government of the United States since 1787.
The Federal Government of Nigeria is the federal government for the Federal Republic of Nigeria, a federation in West Africa, composed of 36 states, who share sovereignty with the federal government and 1 federal territory administered solely by the federal government.
 The federal government is composed of three distinct branches: legislative, executive, and judicial, whose powers are vested by the Constitution of Nigeria in the National Assembly, the President, and the federal courts, including the Supreme Court, respectively.
Most civilian positions in the federal government of the United States are part of the competitive service, where applicants must compete with other applicants in open competition under the merit system administered by the Office of Personnel Management.
 However, some agencies (and some positions within other agencies) are excluded from these provisions.
 Although they primarily operate on a merit basis also, they have their own hiring systems and evaluation criteria.
 These agencies are called excepted service agencies and such positions are part of the excepted civil service.
 The primary common denominator of many of these agencies and positions is that they have national security and/or intelligence functions, such as the Central Intelligence Agency, the Department of State, the Defense Intelligence Agency, the National Security Agency, the Federal Bureau of Investigation, NCIS and the Secret Service.
 Attorney positions, Presidential Management Fellows, Presidential Innovation Fellows, and Foreign Service positions are examples of positions excepted across-the-board in all Federal agencies.
 Not all excepted service members serve in sensitive areas—for example, teachers and administrators at DOD schools, both in the U.S. and overseas, are also excepted, as are all patent examiners.
 In addition, most employees in the legislative branch of the federal government are excepted service employees.
The National Aeronautics and Space Administration (NASA ) is an independent agency of the executive branch of the United States federal government responsible for the civilian space program, as well as aeronautics and aerospace research.
