A prototype satellite and a special vehicle will be sent into space from the Marshall Islands tomorrow from the United States Army's Reagan test site.
Since the mid-1960s, the site has been the primary testing facility for U.S. defence programmes.
The project aims to develop technologies that will help the U.S. to have quick, inexpensive launches with a global reach.
It also seeks to demonstrate the ability to place small satellites into a low earth orbit and launch them at a cost of less than five million dollars.
The satellite was developed by Space Exploration Technology Corporation of California for eight million dollars.
