The futuristic designed XLDron M Gravity is a conceptual vehicle by Oscar Vinals for space tourism, which is in its infancy, but its clear that it will grow.

The XLDron M Gravity ship consists of two parts: an unmanned rocket booster (the XLDron) and a docking station (the M Gravity). The booster would be used to get travelers into orbit. Once the appropriate altitude is reached, Vinals says 65,000 feet should do, the M Gravity pops off of the XLDron and fires up its own engines to reach space. The ship would only be capable of cruising the cosmos for a short amount of time before it would need to be docked again.
