(Web Desk) - A luxury space balloon capsule set carry passengers to the edge of space has splashed down after its first key test.

Florida-based Space Perspective successfully flew an unmanned version of their Spaceship Neptune - Excelsior craft to altitude of about 100,000 feet.

The capsule reached the Earth's atmosphere before making a controlled descent and splashdown after six hours.

The test validated several key technologies that will be used in future commercial spaceflights.

The flight took off from the Marine Spaceport Voyager ship, off the coast of St. Petersburg, Florida, on September 15.

Founder and chief technology officer, Taber MacCallum said: "This is a defining moment for Space Perspective.

"This unmanned flight not only proves our technology but also brings us closer to making space accessible for everyone."

Co-Founder of Space Perspective Jane Poynter said: "This demonstration shows how accessible and gentle our spaceflight experience will be, bringing space travel within reach for more people than ever."

The company plans to start human spaceflights in 2025, with commercial operations beginning in 2026.

To date, more than 1,800 tickets have been sold, with seats costing $125,000 each.

They will enjoy a world-class food and beverage program, comfortable seating, and amenities like custom headphones.

The luxury space balloon will feature five-feet high windows, deep seats, dark, purple tones and subdued lighting, the atmosphere contrasts with the white and sanitised capsules of its competitors.

Wifi connectivity and a drinks bar round out the "Space Lounge" inside the company's Neptune capsule.

Whether it really constitutes spaceflight is a matter of debate.

The balloon reaches an altitude of 20 miles (30 kilometers), much lower than rivals Virgin Galactic, which goes just over 50 miles high, or Blue Origin, which breaches the Karman Line, 62 miles above sea level, the internationally-recognized space border.

But 20 miles is still far higher than commercial planes, which ascend around six miles high.

There's no special training required. The balloon climbs at a serene 12 miles per hour (19 kilometers per hour), and the company pitches itself as a greener, zero-emissions alternative to rocket fuels.

They intend to get the hydrogen for the balloon from renewable sources, rather than extracting it from fossil fuels.

The orbital spacecraft also boasts a "highly customisable" experience for its high-rolling passengers.

"If you can dream it, our team is ready and waiting to work with you to make it a reality," the company writes on its website.

"From the menu and cocktails onboard, to the soundtrack and lighting, your individual preferences may be incorporated into your flight."

The number of passengers is also customisable - depending on how much you're paying.

But in total, the space balloon can fit up to eight tourists onboard.
