You've answered the question already. It is called, "International Space Station", or "ISS" for short. NASA uses the name, "Alpha" to identify it, but the other ISS partners do not.
ALL 16 nations The ISS programme is a joint project among the space agencies of the United States (NASA), Russia (RKA), Japan (JAXA), Canada(CSA) and ten Europeannations (ESA). The Brazilian space agency(AEB) participates through a separate contract with NASA. The Italian space agency(ASI) similarly has separate contracts for various activities not done within the framework of ESA's ISS projects
The ISS is the "International Space Station" run by the US National Aeronautics and Space Administration, or "NASA". Primarily designed and constructed by the US, modules have been contributed by several additional nations and astronauts from many nations have visited the ISS. You can often see the ISS in the pre-dawn or early evening hours. See the "Flybys" link below.

No single person designs a space station, or any large and complex machine nowadays. A NASA space station would be designed by a team commissioned by NASA. The ISS is an international undertaking.
ESA is the European Space Agency, which has been involved in the building of the International Space Station along with NASA and some other countries.

The ISS (International Space Station) is an object that orbits the Earth, and is a joint project of some 17 countries, including RSA, NASA, ESA, JAXA, and the Canadian Space program. NASA and RSA are the largest supporters, regularly sending their astronauts aboard space crafts that they have manufactured and launched to the ISS. The ISS supports many expirements concerning life and the effects of 0 g's for a prolonged period of time. Currently, the Epedition 17 crew, consisting of Cosmonauts and one Astronaut (NASA) are aboard the space station for prolonged periods of time. The next NASA mission to the ISS (126) is scheduled for November, following 125's mission to repair HT. Launch pad 39A has been used recently due to the Constellation project occurences on pad 39B.
