Space Perspective’s Spaceship Neptune is designed to carry passengers in a pressurized capsule to roughly 100,000 feet (about 30.5 kilometers) beneath a giant balloon. That is in the stratosphere, but well below the 100-kilometer Kármán line commonly used as a space boundary. An uncrewed test reached the target altitude in September 2024; passenger flights had not begun in the latest available reporting, dated April 25, 2025.
What Space Perspective is proposing
Florida-based Space Perspective has proposed a paid tourism experience using a hydrogen balloon rather than a rocket. The vehicle, called Spaceship Neptune, consists of a pressurized passenger capsule suspended beneath the balloon. The company’s 2020 concept described a climb to approximately 100,000 feet, a period at altitude for views of Earth, and a gradual descent for ocean recovery.

Founder and CEO Jane Poynter summed up the capsule’s leisure-oriented pitch to Futurism in 2020: “It will have the best view of any loo in the world.” That remark describes the planned restroom and is not evidence that the service is operating.
Is 100,000 feet actually space?
No—not under the boundary used in the original coverage. At about 30.5 kilometers, the proposed altitude is firmly in the stratosphere. Futurism compared it with the Kármán line at 100 kilometers (62 miles), a commonly used convention for where outer space begins. The balloon therefore offers a high-altitude, near-space view rather than a flight that reaches that conventional boundary.
#1 Best Overall
The terminology needs care: the FAA says it does not define where space begins. “Edge of space” is Space Perspective’s aspirational language; “balloon ride to the stratosphere” is the more precise description of the altitude reported for Neptune.
What has flown so far?
Uncrewed test in September 2024
Space.com reported that Space Perspective launched its first full uncrewed Spaceship Neptune Excelsior test from the company’s Marine Spaceport Voyager vessel off St. Petersburg, Florida, on September 15, 2024. The balloon carried an instrumented capsule to approximately 100,000 feet, followed by a slow descent and recovery from the ocean.

This demonstrates a completed uncrewed test flight of the system. It does not demonstrate that paying passengers have flown. The same report quoted a plan for crewed test flights in 2025; that was a forecast at the time, not confirmation that those flights occurred.

There is no evidence in the available reporting that consumer flights began. Travel Weekly reported on April 25, 2025 that the company appeared to have ceased operations after eviction proceedings. Its website was still online and appeared to accept bookings, but its listed phone number was disconnected, its social-media activity had stopped in December, and the company did not answer inquiries.
That report is the latest status evidence available here, and it is more than a year old relative to this article’s research date. Consequently, current operations, reservation fulfillment, and availability remain unverified. A live booking page should not be treated as proof that a flight is scheduled or that a deposit is protected.
What did a seat cost?
In a December 2023 press release, Space Perspective advertised the following prices:
Rank #4
| Offering | Advertised price | What the figure means |
|---|---|---|
| Individual seat | $125,000 | Historical company-advertised price; not verified as a current offer |
| Entire capsule for eight seats | $1,000,000 | Historical company-advertised price; not verified as a current offer |
These are claims about what the company marketed in 2023, not independent confirmation that seats were sold, flights operated, or prices remain available. No current price or valid reservation channel is established by the cited reporting.
How the balloon concept differs from rocket tourism
The two experiences should not be described as interchangeable. Neptune’s proposal emphasizes a gentle ascent to the stratosphere; rocket-powered tourism uses propulsion and, depending on the vehicle and mission, may cross a chosen space boundary. The available sources do not provide a full, current competitor comparison, but the key distinctions are clear:
Best Value
| Question | Spaceship Neptune proposal | Rocket-powered tourism |
|---|---|---|
| Altitude | Approximately 100,000 feet (30.5 km) | Not stated in the cited material |
| Crosses 100-km Kármán line? | No | Not stated; depends on vehicle and mission |
| Propulsion | High-altitude balloon with capsule | Rocket propulsion |
| Passenger service evidence | Uncrewed test reported in 2024; crewed service not established | Not evaluated by the cited sources |
| Current booking availability | Unverified; 2025 reporting raised serious operational doubts | Not evaluated by the cited sources |
What FAA rules do—and do not—tell you
The FAA licenses commercial space launches and reentries to protect the public, but it does not certify vehicles as safe for carrying humans. Its informed-consent framework requires operators to disclose that the government has not certified a vehicle as safe for human occupants and to give participants an opportunity to ask questions. Congress has also limited the FAA’s authority over occupant safety; the agency’s current moratorium is scheduled to expire January 1, 2028.
Those are general U.S. commercial-human-spaceflight rules. They do not establish that Space Perspective currently holds a particular license, approval, or authorization. The available sources therefore cannot confirm the company’s specific regulatory status.
What a prospective customer should verify
- Whether the company is operating and responding through independently verifiable channels.
- Whether a specific flight date, launch location, refund policy, and escrow or payment protections are documented in a current contract.
- Whether the quoted price is current and what taxes, travel, insurance, training, and cancellation terms it includes.
- What informed-consent disclosures and regulatory authorizations apply to the exact flight.
- Whether the booking is for an actual scheduled passenger mission rather than an expression of interest or legacy reservation.
Bottom line on the “balloon to space” headline
Space Perspective’s idea is a balloon ascent to about 100,000 feet in the stratosphere, not a trip to the 100-kilometer Kármán line. A full uncrewed test reached that altitude in 2024, but passenger service was not established. The $125,000 seat and $1 million capsule prices are historical 2023 advertisements, and an April 2025 report questioned whether the company was still operating. Treat any present-day booking or availability claim as unverified until the company’s operations, contract, and regulatory status can be independently confirmed.
