However, funding was not secured. There have been no updates as to their progress. # 2012 - 2014: Systems planning and enterprise planning were to happen . # 2014: Robotic precursor missions, lasting two to three years, were projected to begin as early as 2014. # 2014 (concurrent): Establish prototyping and engineering infrastructure in LEO to test interchangeable modules. # Establish production-scale equipment and transport vehicles, both in LEO and on the surface of the Moon.
