Question: The Goldstone Solar System Radar is similar to the radar at which Puerto Rican facility?
Context: The Puerto Rican Figure Skating Championships are the figure skating national championships held annually to crown the national champions of Puerto Rico.  Skaters compete in the disciplines of men's singles and ladies singles across the levels of senior (Olympic-level), junior, novice, intermediate, and juvenile.  Not every event has been held in every year due to a lack of entries.  The National Championships are organized by the Puerto Rican Figure Skating Federation.  The Puerto Rican Figure Skating Federation is not affiliated with the Puerto Rico Olympic Committee (In Spanish, Comite Olimpico de Puerto Rico), and therefore can not represent Puerto Rico internationally or compete in the Winter Olympic Games.  Although the Puerto Rican Figure Skating Federation became a member of the International Skating Union, the Puerto Rico Olympic Committee has not recognized it, nor is listed in the Puerto Rico Olympic Committee website.  The Puerto Rican Figure Skating Federation is essentially a club seeking recognition by the Puerto Rico Olympic Committee.  Created and formed by the family of the first Puerto Rican figure skater Kristine Stone Cruz (who trained in the Ice House in Hackensack New Jersey).  She held the title 2 years in a row.  Kristine is now coaching as well as skating in Omaha, Nebraska at the Ralston Arena. Dr. Leopoldo Figueroa (September 21, 1887 – October 15, 1969) a.k.a. "The deacon of the Puerto Rican Legislature", was a Puerto Rican politician, journalist, medical doctor and lawyer.  Figueroa, who began his political career as an advocate of Puerto Rican Independence, was the co-founder of the "Independence Association", one of three political organizations which merged to form the Puerto Rican Nationalist Party.  Figueroa, had changed political ideals and in 1948, was a member of the "Partido Estadista Puertorriqueño" (Puerto Rican Statehood Party).  That year, he was the only member of the Puerto Rico House of Representatives who did not belong to the Popular Democratic Party of Puerto Rico PPD, who opposed the PPD's approval of the infamous Law 53, also known as "Puerto Rico's Gag Law" and "Ley de La Mordaza", which violated the civil rights of those who favored Puerto Rican Independence.  On December 22, 2006, the Puerto Rican Legislature approved a law declaring every September 21, Leopoldo Figueroa Carreras Day. (85989) 1999 JD is an Aten asteroid, near-Earth object, and potentially hazardous object in the inner Solar System that makes frequent close approaches to Earth and Venus.  On the Earth approach in 2015, it was observed by the Goldstone Solar System Radar and found to be a contact binary with the largest axis approximately 2 kilometers wide, and each lobe about 200–300 meters large.  Although 1999 JD in its current orbit never passes closer than 0.047 AU to Earth, it is listed as a potentially hazardous object because it is large and might pose a threat in the future. The Arecibo Observatory is a radio telescope in the municipality of Arecibo, Puerto Rico.  This observatory is operated by SRI International, USRA and UMET, under cooperative agreement with the National Science Foundation (NSF).  The observatory is the sole facility of the National Astronomy and Ionosphere Center (NAIC), which refers to the observatory, and the staff that operates it.  From its construction in the 1960s until 2011, the observatory was managed by Cornell University. The National Museum of Puerto Rican Arts and Culture (formerly "Institute of Puerto Rican Arts and Culture") is a museum in Chicago dedicated to interpreting the arts and culture of the Puerto Rican people and of the Puerto Ricans in Chicago.  Founded in 2001, it is housed in the historic landmark Humboldt Park stables and receptory, near the Paseo Boricua.  It hosts visual arts exhibitions, community education, and festivals.  Its exhibitions have featured the artwork of Osvaldo Budet, Elizam Escobar, Antonio Martorell, Ramon Frade Leon, and Lizette Cruz, in addition to local Chicago or Puerto Rican artists.  The Institute also sponsors music events including an annual "Navi-Jazz" performance, described as a "fusion of Puerto Rican and African American musical elements." The Nice ( ) model is a scenario for the dynamical evolution of the Solar System.  It is named for the location of the Observatoire de la Côte d'Azur, where it was initially developed, in Nice, France.  It proposes the migration of the giant planets from an initial compact configuration into their present positions, long after the dissipation of the initial protoplanetary gas disk.  In this way, it differs from earlier models of the Solar System's formation.  This planetary migration is used in dynamical simulations of the Solar System to explain historical events including the Late Heavy Bombardment of the inner Solar System, the formation of the Oort cloud, and the existence of populations of small Solar System bodies including the Kuiper belt, the Neptune and Jupiter trojans, and the numerous resonant trans-Neptunian objects dominated by Neptune.  Its success at reproducing many of the observed features of the Solar System means that it is widely accepted as the current most realistic model of the Solar System's early evolution, although it is not universally favoured among planetary scientists.  Later research revealed a number of differences between the original Nice model's predictions and observations of the current Solar System, for example the orbits of the terrestrial planets and the asteroids, leading to its modification. Puerto Rican citizenship was first legislated by the United States Congress in Article 7 of the Foraker Act of 1900 and later recognized in the Constitution of Puerto Rico.  Puerto Rican citizenship existed before the U.S. takeover of the islands of Puerto Rico and continued afterwards.  Its affirmative standing was also recognized before and after the creation of the Commonwealth of Puerto Rico in 1952.  Puerto Rican citizenship was recognized by the United States Congress in the early twentieth century and continues unchanged after the creation of the Commonwealth of Puerto Rico.  The United States government also continues to recognize a Puerto Rican nationality.  Puerto Rican citizenship is also recognized by the Spanish Government, which recognizes Puerto Ricans as a people with Puerto Rican, and not "American" citizenship.  It also grants Spanish citizenship to Puerto Ricans on the basis of their Puerto Rican, not American, citizenship. Ground Equipment Facility J-31 (San Pedro Hill Air Force Station during the Cold War) is a Joint Surveillance System radar site of the Western Air Defense Sector (WADS) and the Federal Aviation Administration's air traffic control radar network  for the Los Angeles Air Route Traffic Control Center.  The facility's Air Route Surveillance Radar Model 1E with an ATCBI-6 beacon interrogator system are operated by the FAA and provide sector data to North American Aerospace Defense Command.  The site provided Semi-Automatic Ground Environment data to the 1959-66 Norton AFB Direction Center for the USAF Los Angeles Air Defense Sector.  The site also provided Project Nike data to the 1960-74 Fort MacArthur Direction Center ~3 mi away for the smaller US Army Los Angeles Defense Area—as well as gap-filler radar coverage for the 1963-74 Integrated Fire Control area of Malibu Nike battery LA-78 on San Vicente Mountain. The Goldstone Solar System Radar, or GSSR, is a large radar system used for investigating objects in the Solar system.  Located in the desert near Barstow, California, it comprises a 500-kW X-band (8500 MHz) transmitter and a low-noise receiver on the 70-m DSS 14 antenna at the Goldstone Deep Space Communications Complex.  It has been used to investigate Mercury, Venus, Mars, the asteroids, and moons of Jupiter and Saturn.  The most comparable facility is the radar at Arecibo Observatory. Antonio Vélez Alvarado a.k.a. "The Father of the Puerto Rican Flag" (June 12, 1864 – January 16, 1948) was a Puerto Rican journalist, politician and revolutionary who was an advocate of Puerto Rican independence.  A close friend of Cuban patriot José Martí, Vélez Alvarado joined the Puerto Rican Revolutionary Committee in New York City and is among those who allegedly designed the Flag of Puerto Rico.  Vélez Alvarado was one of the founding fathers of the Puerto Rican Nationalist Party.
