.com

The domain name com is a top-level domain (TLD) in the Domain Name System of the Internet. Its name is derived from the word commercial, indicating its original intended purpose for domains registered by commercial organizations. However, eventually the distinction was lost when .com, .org and .net were opened for unrestricted registration.

The domain was originally administered by the United States Department of Defense, but is today operated by Verisign, and remains under ultimate jurisdiction of U.S. law. Verisign Registrations in com are processed via registrars accredited by ICANN. The registry accepts internationalized domain names.

The domain was one of the original top-level domains (TLDs) in the Internet when the Domain Name System was implemented in January 1985, the others being edu, gov, mil, net, org, and arpa. It has grown into the largest top-level domain.

History

The domain com was as one of the first set of top-level domains when the Domain Name System was first implemented for use on the Internet in January 1985. The domain was administered by the U.S. Department of Defense (DoD), however the department contracted the domain maintenance to SRI International. SRI created DDN-NIC, also known as SRI-NIC, or simply the NIC (Network Information Center), then accessible online with the domain name nic.ddn.mil. Beginning October 1, 1991, an operations contract was awarded to Government Systems Inc. (GSI), which sub-contracted it to Network Solutions Inc. (NSI).

Dude Perfect

Dude Perfect is a sports entertainment group who got their start on YouTube. Most known for their trick shots, they are also involved in comedy with their "Stereotypes" series, in which they poke fun at common stereotypes, mostly in the sports world. The group consists of the twins Coby and Cory Cotton, Garrett Hilbert, Cody Jones, and Tyler Toney who are all former high school basketball players and college roommates at Texas A&M University.

The group commented that their shots typically relied more on American football skills than basketball.

History

The group was betting on sandwiches via basketball shots in their backyard, which were eventually recorded on camera, and a video of trick shots at Toney's ranch was eventually released on YouTube. Within a week, the video received 100,000 views. When asked about the name, Toney stated,

Afterwards, a trick shot video from the Christian summer camp Sky Ranch was released, which, as of June 2015, has over 13.9 million views. For every 100,000 views the video received, Dude Perfect pledged to sponsor a child from Compassion International. Afterwards, ESPN's E:60 contacted the group for a segment, and on the third floor of Texas A&M's Kyle Field, Toney converted a shot, which traveled 3.9 seconds, which was a world record at the time. The shot prompted television appearances on ESPN's First Take, Pardon the Interruption, Around the Horn and SportsNation. Eventually, Dude Perfect introduced the Panda mascot, who "developed a cult following at A&M basketball games" when taunting players of the opposing team.

Space station

A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting a crew, which is designed to remain in space (most commonly as an artificial satellite in low Earth orbit) for an extended period of time and for other spacecraft to dock. A space station is distinguished from other spacecraft used for human spaceflight by lack of major propulsion or landing systems. Instead, other vehicles transport people and cargo to and from the station. As of September 2014 two space stations are in orbit: the International Space Station, which is permanently manned, and China's Tiangong-1 (which successfully launched on September 29, 2011), which is unmanned most of the time. Previous stations include the Almaz and Salyut series, Skylab and most recently Mir.

Today's space stations are research platforms, used to study the effects of long-term space flight on the human body as well as to provide platforms for greater number and length of scientific studies than available on other space vehicles. Each crew member staying aboard the station for weeks or months, but rarely more than a year. Most of the time crew remain at station but its not necessary that crew should have to be stay at station. Since the ill-fated flight of Soyuz 11 to Salyut 1, all manned spaceflight duration records have been set aboard space stations. The duration record for a single spaceflight is 437.7 days, set by Valeriy Polyakov aboard Mir from 1994 to 1995. As of 2013, three astronauts have completed single missions of over a year, all aboard Mir.

International Space Station

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component launched into orbit in 1998, and the ISS is now the largest artificial body in orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurised modules, external trusses, solar arrays, and other components. ISS components have been launched by Russian Proton and Soyuz rockets as well as American Space Shuttles.

The ISS serves as a microgravity and space environment research laboratory in which crew members conduct experiments in biology, human biology, physics, astronomy, meteorology, and other fields. The station is suited for the testing of spacecraft systems and equipment required for missions to the Moon and Mars. The ISS maintains an orbit with an altitude of between 330 and 435 km (205 and 270 mi) by means of reboost manoeuvres using the engines of the Zvezda module or visiting spacecraft. It completes 15.54 orbits per day.
