Summary

The video, presented by Hugo Lisoir, explores the current state and future of space tourism. It begins by noting that 2019 might finally be the year space tourism becomes a reality, despite decades of delays. The video distinguishes between suborbital and orbital tourism, highlighting that orbital tourism has already occurred with Space Adventures sending seven clients to the ISS between 2001 and 2009. It then focuses on the two main companies, Virgin Galactic and Blue Origin, which are developing suborbital vehicles. Virgin Galactic’s SpaceShipTwo is an air-launched spaceplane, while Blue Origin’s New Shepard is a reusable rocket and capsule. Both aim to offer brief suborbital flights with a few minutes of weightlessness, at a cost of around $250,000. The video discusses the technical challenges, safety concerns, and the need for reusable vehicles to reduce costs. It also mentions other projects, such as SpaceX’s Starship and Space Adventures’ lunar mission. The video concludes by discussing the potential benefits of space tourism, such as inspiring a new generation and driving down costs, but also acknowledges its environmental impact and the fact that it will initially be reserved for the wealthy.
