Space tourism startup Space Perspective has raised a new $7 million in seed funding, from investors including Prime Movers Lab and Base Ventures . The company, founded by Jane Poynter and Taber MacCallum, who previously founded stratospheric balloon company World View, is focused on developing Spaceship Neptune, a pressurized passenger capsule that is meant to be carried by an ultra-high altitude balloon to the very edge of space to provide passengers with an unparalleled view.

Spaceship Neptune is designed to carry up to eight passengers per trip, on a six-hour journey that will include two hours spent at the upper edge of Earth’s atmosphere and a water landing in the Atlantic Ocean. The first test flight is currently targeted for the end of the first quarter of 2021, according to Space Perspective, and it will involve flying an uncrewed Neptune capsule prototype, which also won’t have the pressurized cabin of the final version.

From there, the plan is to test and develop systems necessary for Neptune to take up its first human passengers, with the goal of doing that by sometime around 2024, with ticket pre-sales launching from 2021 for interested, deep-pocketed parties.

Poynter and MacCallum’s prior venture World View originally included human stratospheric space tourism trips as part of its business model, but the company has since pivoted to focus on scientific and commercial communication and observation payloads exclusively under its current leadership. World View appointed Ryan Hartman as CEO in 2018, replacing Poynter in the top spot.
