Japan successfully launches, lands reusable rocket

Japan's space agency said on Saturday its prototype reusable rocket successfully completed the first lift-off and landing test, marking a step forward in the cost-cutting technology dominated by SpaceX.

Most rockets are designed for single use, with components falling into the sea, burning up in the atmosphere or remaining in orbit as debris. The first launch stage is considered the most expensive component. But the deployment of partially reusable rockets would slash launch costs.
