full_context: Document 1: Space Race: Von Braun and his team were sent to the United States Army's White Sands Proving Ground, located in New Mexico, in 1945. They set about assembling the captured V2s and began a program of launching them and instructing American engineers in their operation. These tests led to the first rocket to take photos from outer space, and the first two-stage rocket, the WAC Corporal-V2 combination, in 1949. The German rocket team was moved from Fort Bliss to the Army's new Redstone Arsenal, located in Huntsville, Alabama, in 1950. From here, von Braun and his team would develop the Army's first operational medium-range ballistic missile, the Redstone rocket, that would, in slightly modified versions, launch both America's first satellite, and the first piloted Mercury space missions. It became the basis for both the Jupiter and Saturn family of rockets.
Document 2: Virgin Galactic: Virgin Galactic is a British spaceflight company within the Virgin Group. It is developing commercial spacecraft and aims to provide suborbital spaceflights to space tourists and suborbital launches for space science missions. Virgin Galactic plans to provide orbital human spaceflights as well. SpaceShipTwo, Virgin Galactic's suborbital spacecraft, is air launched from beneath a carrier airplane known as White Knight Two.
Document 3: Oceanic (unfinished ship): The RMMV "Oceanic" (Royal Mail Motor Vessel) was the planned name of an unfinished ocean liner that was partially built by Harland and Wolff for the White Star Line. The ship was to have been the first -long ocean liner. It was intended to be the largest ocean liner for the White Star Line, thus it would have been larger than the earlier White Star giants, "Olympic", "Titanic", "Britannic", and "Majestic."
Document 4: New Mexico Territory: The Territory of New Mexico was an organized incorporated territory of the United States that existed (with varying boundaries) from September 9, 1850, until January 6, 1912, when the remaining extent of the territory was admitted to the Union as the State of New Mexico, making it the longest - lived organized incorporated territory of the United States, lasting approximately 62 years.
Document 5: Lockheed Martin VH-71 Kestrel: The Lockheed Martin VH-71 Kestrel was a variant of the AgustaWestland AW101 (formerly the EH101) that was being manufactured to replace the United States Marine Corps' Marine One U.S. Presidential transport fleet. Originally marketed for various competitions as the "US101", it was developed and manufactured in the US by a consortium headed by Lockheed Martin, consisting of Lockheed Martin Systems Integration – Owego (LMSI), AgustaWestland and Bell Helicopter.
Document 6: Airport: Most of the world's airports are owned by local, regional, or national government bodies who then lease the airport to private corporations who oversee the airport's operation. For example, in the United Kingdom the state-owned British Airports Authority originally operated eight of the nation's major commercial airports - it was subsequently privatized in the late 1980s, and following its takeover by the Spanish Ferrovial consortium in 2006, has been further divested and downsized to operating just five. Germany's Frankfurt Airport is managed by the quasi-private firm Fraport. While in India GMR Group operates, through joint ventures, Indira Gandhi International Airport and Rajiv Gandhi International Airport. Bengaluru International Airport and Chhatrapati Shivaji International Airport are controlled by GVK Group. The rest of India's airports are managed by the Airports Authority of India.
Document 7: New Mexico: Inhabited by Native Americans for thousands of years before European exploration, it was colonized by the Spanish in 1598 as part of the Imperial Spanish viceroyalty of New Spain. It was named Nuevo México after the Aztec Valley of Mexico by Spanish settlers, 223 years before the establishment of the present - day country of Mexico. The present - day state of New Mexico was not named after, nor is it a part of, Mexico. Its geographic characteristics made settlement and effective political control difficult which prompted Mexico's invasion and control of the area from 1824 to 1846. New Mexico's Spanish origins made cultural integration with Mexico unsuitable, which sparked the Revolt of 1837 and a growing economic association with the expanding United States. The 1848 Mexican -- American War indirectly capitalized on this tension and created the U.S. New Mexico Territory. It was admitted to the Union as the 47th state on January 6, 1912.
Document 8: New Mexico Spaceport Authority: The state of New Mexico has privatized the operations of Spaceport America; the spaceport will be operated by Virgin Galactic, a component of the Virgin Group of global companies operated by Sir Richard Branson. While the Spaceport Authority will exercise public-sector oversight, Virgin Galactic will be the "anchor tenant" of the spaceport.
Document 9: Israel: The Israeli Space Agency coordinates all Israeli space research programs with scientific and commercial goals. In 2012 Israel was ranked ninth in the world by the Futron's Space Competitiveness Index. Israel is one of only seven countries that both build their own satellites and launch their own launchers. The Shavit is a space launch vehicle produced by Israel to launch small satellites into low earth orbit. It was first launched in 1988, making Israel the eighth nation to have a space launch capability. Shavit rockets are launched from the spaceport at the Palmachim Airbase by the Israeli Space Agency. Since 1988 Israel Aerospace Industries have indigenously designed and built at least 13 commercial, research and spy satellites. Some of Israel's satellites are ranked among the world's most advanced space systems. In 2003, Ilan Ramon became Israel's first astronaut, serving as payload specialist of STS-107, the fatal mission of the Space Shuttle Columbia.

Document 11: Entwicklungsring Nord: West Germany provided 53.3% of Spacelab's cost and fulfilled 52.6% of all Spacelab work contracts. ERNO VFW Fokker, in competition with MBB, submitted the winning design, and became the prime contractor for Spacelab. MBB in 1981 took over VFW Fokker. The ERNO plant in Bremen continued as the headquarters for Spacelab design, production management, component testing, and assembly. It became a part of EADS Astrium Space Transportation, then Airbus Defence and Space, then Airbus Safran Launchers, and now ArianeGroup.
Document 12: VMS Eve: VMS "Eve" is the first, and so far only, White Knight Two, built by Scaled Composites for Virgin Galactic. The "VMS" prefix stands for "Virgin Mothership".
Document 13: New Mexico: Inhabited by Native Americans for thousands of years before European exploration, it was colonized by the Spanish in 1598 as part of the Imperial Spanish viceroyalty of New Spain. In 1563, it was named Nuevo México after the Aztec Valley of Mexico by Spanish settlers, 223 years before the establishment and naming of the present - day country of Mexico; thus, the present - day state of New Mexico was not named after the country today known as Mexico. Its geographic characteristics made settlement and effective political control difficult which prompted Mexico's invasion and control of the area from 1824 to 1846. New Mexico's Spanish origins made cultural integration with Mexico unsuitable, which sparked the Revolt of 1837 and a growing economic association with the expanding United States. The 1848 Mexican -- American War indirectly capitalized on this tension and created the U.S. New Mexico Territory. It was admitted to the Union as the 47th state on January 6, 1912.

Document 15: Dakota Territory: The Territory of Dakota was an organized incorporated territory of the United States that existed from March 2, 1861, until November 2, 1889, when the final extent of the reduced territory was split and admitted to the Union as the states of North and South Dakota.
