Space Perspective, known for offering carbon-neutral spaceflight experiences, has successfully conducted a full flight profile of its uncrewed Spaceship Neptune-Excelsior, marking another milestone toward crewed missions. The flight took off from Marine Spaceport (MS) Voyager near St. Petersburg, Florida, on September 15, 2024. This demonstration showcased the capabilities of the vehicle that will eventually carry passengers to space and represented a critical step forward in the development process.

During the six-hour journey, the spacecraft ascended to an altitude of about 100,000 feet, passing through 99% of Earth's atmosphere. After reaching its peak altitude, the craft made a controlled descent and splashdown, fully demonstrating its technological advancements and operational readiness.

"Completing Development Flight 2 is a defining moment for Space Perspective," said Taber MacCallum, Founder and CTO of Space Perspective. "I'm so proud of our devoted team who has worked relentlessly to execute this mission, drawing from their deep expertise and designing solutions for never-been-seen technologies. This uncrewed flight not only proves our pioneering technology but also brings us a giant leap closer to making space accessible for everyone and reaffirms our belief in the transformative power of space travel."

Several notable accomplishments were highlighted during the flight:

- Launch and Ascent: The launch from MS Voyager employed Space Perspective's patented four-roller system to lift the balloon, marking a first in marine spaceport operations. This innovation enables year-round global flights from marine locations.

- Spaceship Neptune Capsule: The test flight verified the cabin's ability to maintain pressure and stability, confirming the safety and performance of the largest spaceflight capsule flown to date, equipped with the largest windows ever used for space travel.

- Thermal Management: The vehicle's advanced thermal control system efficiently managed temperature changes from the upper atmosphere's cold to the intense solar heat, ensuring a comfortable interior environment for future passengers.

- SpaceBalloon Performance: Powered by hydrogen lift gas, the SpaceBalloon lifted the spacecraft to the edge of space and successfully descended, proving the capability of renewable lift gas technologies.

- Mission Control and Retrieval: The flight validated the spacecraft's proprietary software, communication systems, and retrieval process, with the post-flight inspection conducted smoothly using a fast boat and crane.

Jane Poynter, Founder of Space Perspective, noted: "This flight successfully demonstrated the extraordinary accessibility of Spaceship Neptune's spaceflight experience with its gentle ascent, descent and splashdown, a critical step in opening space up to more people than ever before possible. Our advances in marine spaceport technology, spacecraft design, and flight safety are setting truly new standards for the future of space exploration."

Data collected from this flight will enhance Space Perspective's digital twin technology, a tool that allows engineers to analyze spacecraft systems and guide future designs. These insights will be vital as the company progresses toward crewed test flights.

To date, Space Perspective has raised $100M, with investment from Prime Movers Lab and other venture capital firms like LightShed Partners, E2MC, and SpaceFund. The company aims to begin human flights in 2025, with commercial operations planned for 2026. Tickets for a seat aboard Spaceship Neptune are priced at $125,000, with over 1,800 reservations already made.
