Space Perspective has announced the completion of its new "marine spaceport" where its stratospheric balloons will take intrepid tourists to the edge of space. The vessel, Marine Spaceport (MS) Voyager (named in commemoration of Voyager 1 interstellar probe mission), took two years to build. Space Perspective says it is the first-ever spaceport that will be on open water versus a traditional land-based launch facility, and will be located on the Space Coast of Florida.

The massive world-class powerhouse spans 294 feet (90 meters) long and is equipped to both launch and retrieve the spaceflight experience company's SpaceBalloons , pressurized modules that will transport travelers on a six-hour expedition to the edge of space. "The capability to launch and retrieve the Neptune capsule at sea creates worldwide scalability along with an unprecedented closure of the routine operations safety case," Taber MacCallum, founder and co-CEO of Space Perspective, said in a press release. "We are proud to bring a new spaceflight capability to Port Canaveral and the Space Coast.

" The launch system includes a set of rollers that will assist in preparing the balloons for liftoff, moving them around while in the vertical position on the 200-foot (61-meter) deck. This will help minimize the launch footprint versus typical balloon launches by allowing them to take place without the assistance of aircraft carriers. Space Perspective says the vessel also has extra maneuverability built with four g.
