If you ever wanted to have a martini in space - here's your chance. 

Space Perspective has finalized its design for Spaceship Neptune, a sleek-looking capsule that will offer epic views 20 miles above Earth and luxury amenities - if you don't mind forking over $125,000 per ticket.

Unlike Jeff Bezos' Blue Origin and Richard Branson's Virgin Galactic, which have the all the flight turbulence one would expect from a rocket and a plane - plus the ability to float free thanks to zero gravity - Space Perspective promises a calm experience since its spherical pod is being propelled into the planet's stratosphere by a balloon.

The Florida-based company, which is constructing Spaceship Neptune near NASA's Kennedy Space Center, is planning to offer up to eight passengers at a time the chance to soak up panoramic views of Earth during the six-hour round trip.
