Francium is a chemical element with the symbol Fr and atomic number 87. It is extremely radioactive; its most stable isotope, francium-223, has a half-life of only 22 minutes. It is the second-most electropositive element, behind only caesium, and is the second rarest naturally occurring element. The isotopes of francium decay quickly into astatine, radium, and radon. The electronic structure of a francium atom is [Rn] 7s1, and so the element is classed as an alkali metal.
The 5.56×45mm NATO is a rimless bottlenecked intermediate cartridge family developed in the late 1970s in Belgium by FN Herstal. It consists of the SS109, L110, and SS111 cartridges. On 28 October 1980, under STANAG 4172, it was standardized as the second standard service rifle cartridge for NATO forces as well as many non-NATO countries. Though they are not entirely identical, the 5.56×45mm NATO cartridge family was derived from and is dimensionally similar to the .223 Remington cartridge designed by Remington Arms in the early 1960s.
Mendoza, officially the City of Mendoza is the capital of the province of Mendoza in Argentina. It is located in the northern-central part of the province, in a region of foothills and high plains, on the eastern side of the Andes.

The .223 Remington is a rimless, bottlenecked rifle cartridge. It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create a small-caliber, high-velocity firearm. The .223 Remington is considered one of the most popular common-use cartridges and is currently used by a wide range of semi-automatic and manual-action rifles as well as handguns.
The Heckler & Koch HK416 is a gas-operated assault rifle chambered for the 5.56×45mm NATO cartridge. It is designed and manufactured by the German company Heckler & Koch.
The Focke-Achgelis Fa 223 Drache was a helicopter developed by Germany during World War II. A single 750-kilowatt (1,010 hp) Bramo 323 radial engine powered two three-bladed 11.9-metre (39 ft) rotors mounted on twin booms on either side of the 12.2-metre-long (40 ft) cylindrical fuselage. Although the Fa 223 is noted for being the first helicopter to attain production status, production of the helicopter was hampered by Allied bombing of the factory, and only 20 were built.
Iota Sagittarii is a star in the zodiac constellation of Sagittarius. With an apparent visual magnitude of +4.118, it is bright enough to be viewed with the naked eye. Based upon an annual parallax shift of 17.94 mas as seen from Earth, this star is located 182 light years from the Sun. It is moving away from the Earth with a radial velocity of +35.8 km/s.
The Farman F.220 and its derivatives were thick-sectioned, high-winged, four engined monoplanes from Farman Aviation Works. Based on the push-pull configuration proven by the F.211, design started in August 1925 and the first flight of the prototype was on 26 May 1932. The definitive F.222 variant was the biggest bomber to serve in France between the world wars. One variant was designed as an airliner.
USS De Grasse (AP-164/AK-223), originally SS Nathaniel J. Wyeth, was a Crater-class cargo ship active with the United States Navy during World War II. It was the second ship of the Navy to bear the name De Grasse, named after French Admiral François Joseph Paul de Grasse.

Zeta2 Scorpii is a K-type orange giant star in the constellation of Scorpius. It has an apparent visual magnitude which varies between 3.59 and 3.65, and is located near the blue-white supergiant star ζ1 Scorpii in Earth's sky. In astronomical terms, ζ2 is much closer to the Sun and unrelated to ζ1 except for line-of sight co-incidence. ζ1 is 5,700 light-years away and probably an outlying member of open star cluster NGC 6231, whereas ζ2 is a mere 132 lightyears distant and thus much less luminous in real terms. ζ2 can also be distinguished from its optical partner, ζ1, because of its orangish colour especially in long-exposure astrophotographs.
Kepler-223 is a G5V star with an extrasolar planetary system discovered by the Kepler mission. Studies indicate that the Kepler-223 star system consists of 4 planets orbiting the star.

Abell 223 is a galaxy cluster. It is located at a distance of 2.4 billion light-years from Earth. The cluster is connected to nearby cluster Abell 222 by a filament of matter. Research has shown that only 20% of that matter is normal. The rest is thought to be dark matter. This means that this would form the Abell 222/ Abell 223 Supercluster as we understand them.
HD 181342 is a star in the constellation of Sagittarius. With an apparent magnitude of 7.55, it cannot be seen with the naked eye. Parallax measurements made by Gaia spacecraft put the star at a distance of 394 light-years away.
