Payload Aerospace S.L. (PLD Space) is a Spanish company developing two partially-reusable launch vehicles called Miura 1 and Miura 5. Miura 1 is designed as a sounding rocket for sub-orbital flights to perform research or technology development in microgravity environment and/or in the upper atmosphere. Furthermore, Miura 1 is also serving as the technological demonstrator of the orbital launcher Miura 5. Miura 5 will provide orbital launch capabilities for small payloads such as CubeSats or microsatellites, that need a flexible and dedicated launch vehicle and therefore can not fly with traditional launch vehicles. It is being designed to deliver a total payload mass up to 300 kg (660 lb) into low Earth orbit.
