Take a look at the 'world's only carbon-neutral spaceship'

Florida-based Space Perspective claims that its edge-of-space balloon trips will "the only carbon-neutral, zero-emission way" to enjoy suborbital adventures. New pictures reveal a roomier new capsule design.

(CNN) — The space tourism race is now firing on all rockets, but one company is hoping to carve out a niche as "the only carbon-neutral, zero-emission way" to travel to the edge of space.

Florida-based Space Perspective plans to take passengers up to 100,000 feet for suborbital adventures in a pressurized capsule suspended from an enormous high-tech version of a hot-air balloon. New images released July 27 show the latest patented capsule design for its Spaceship Neptune craft.

It's a roomier interior than in previous iterations, with a spherical capsule design affording travelers more head height, as well as adding the safety benefit of being optimal for pressure resistance. And we get a better look at the luxury Space Lounge, with its deep reclining seats, mood lighting and well-stocked bar.
