Figure skating jumps
Jumps are referred to by how many times the skater turns in the air. One revolution (one and a half for the Axel) is a "single" jump. Two revolutions (two and a half for the Axel) is a "double" jump. Three revolutions (three and a half for the Axel) is a "triple" jump. Four revolutions (four and a half for the Axel, although this has never been done in competition) is a "quadruple" or "quad" jump. The first triple jump landed in competition was a loop jump. It was landed by Dick Button in 1952. The first quadruple jump landed in competition was a toe loop jump. It was landed by Kurt Browning in 1988. Currently, men in world-class competition usually attempt a full set of triples and sometimes one or two quadruple jumps in their free skating programs. Triple Axels are rare for ladies, and quadruple jump attempts even more so.
6469 Armstrong
On 20 July 1969, Armstrong was one of the first two humans to land on the Moon, and the first person to walk on it, shortly followed by Buzz Aldrin, after whom the asteroid 6470 Aldrin is named. The minor planet 6471 Collins is named after the third crew member of the Apollo 11 mission. In 1966, Armstrong also conducted the first docking in space together with David Scott aboard Gemini 8. The asteroid's name was suggested by Czech astronomers Jana Tichá, Miloš Tichý and Zdeněk Moravec, who observed it during its 1995-opposition, shortly before being numbered. The lunar crater "Armstrong" is also named in his honor. The approved naming citation was published by the Minor Planet Center on 4 May 1999 ().
