Private aerospace companies and NASA have been developing space taxis to replace the US Space Shuttles that retired their last ship in July 2011. As of August 2014, America now has three companies producing space taxis to shuttle both supplies and humans back and forth between Earth and the International Space Station.

NASA partnered with an initial 63 aerospace companies before July 2011 in order to continue development of important aerospace developments in the public and private sectors. The American Space Agency then chose six companies to design proposed space taxis to replace the US Space Shuttle and to eliminate dependency on Russian shuttles.

From among the work of six top companies, NASA chose three firms to further develop the aerospace vehicles America needs/ These three big-name companies are:

  1. SpaceX under Elon Musk,
  2. Sierra Nevada, and
  3. Boeing.

The development that the Unbited States needs at this time is one that reduces the time of the journey to the ISS. The US Shuttles took about 2.5 days to reach the space station, but Russian shuttles, launched from a higher latitude, require only 6 hours of flight time. A possibility exists in a northern US State and aerospace jobs will increase with time at that location.
