The next evaluation of transportation across the globe is suborbital by using reusable rockets or space planes.

Modular Transport System (MTS) enables, during times of natural disaster, the ability to transport critical commodities and services, like food, water and medical supplies, by traditional transportation into the disaster area can take an excessive amount of time, thus increasing the suffering of those affected. Additionally, the infrastructure required for the distribution of those supplies and services usually is severely impacted by the disaster, thus delaying getting those things to those who need them most.

MTS has the ability to deliver bulk cargo, personnel and other needed services within 60 minutes of launch to anywhere in the world. Because of its modularity, reusability, and rapid turnaround times, response time is dramatically reduced. It is estimated that MTS can deliver up to 100 tons of supplies to unimproved landing areas without establishing launch support infrastructure and propellant.

The MTS architecture allows for the transportation of large-scale infrastructure (such as habitable space modules and refuelling depots), equipment and supplies to enable an increased presence and growth on orbit in order to enable the next steps to the Moon, Mars and beyond.

Our reusable system architecture enables large-scale deployment of critical required infrastructure and commodities to support establishing and growing a lunar base.  It can land large turn-key infrastructure to support initial and long-term bases and outposts.  Deploy large/oversized and heavy equipment critical construction initial and enduring facilities on the surface.  Then support the sustainment of heavy cargo and supplies transportation to and resources from the Moon to enable an enduring and growing presence on the moon.
