With our high thrust, safe, and inexpensive propulsion system technology for small satellites, we will promote groundbreaking advances in space propulsion and contribute to the improvement of Earth orbital activities and future human economic activities that will reach deep space.

The human economic sphere is being extended into Earth orbit along with the growing demand for small spacecraft. Space stations may be built on the Moon or Mars in the near future. When this happens, a new transportation in space will be needed is. Transportation from space hubs to local destinations, i.e., "last-mile transportation," will be critical to the future space economy. Unfortunately, existing space propulsion technologies can only utilize very dangerous propellants, or are time-consuming low-power propulsion systems. The key technology to achieve last-mile transportation in space is a propulsion system that is compact, safe, affordable, fast, storable, and controllable (throttling capable). We believe that Letara's technology will not only improve existing Earth orbital activities, but will also be a mainstay of future human economic activity extending into deep space.

What is "Letara"

Letara means "pure white" in the language of the Ainu, the indigenous people of Hokkaido.
Letara is based in Sapporo, Hokkaido, and the name reflects the image of our "snowy white" landscape in Winter. The name also implies the newness of a start-up company, and the ability to take on the appearance of other colors in the future.
