ISISPACE's Deep Space Deployer is a multi-stage CubeSat deployment system with low-velocity release and umbilical support for deep-space missions.
The ISISPACE Deep Space Deployer (DSD) is a CubeSat deployer designed for deep-space mission profiles, incorporating a multi-stage separation architecture.[1][2] It accommodates payloads up to the 6U XL CubeSat class, with a maximum stated payload mass of 12.5 kg.[1] The deployer itself masses 4.9 kg.[1] Closed envelope dimensions are 272 x 156.7 x 432.4 mm; open envelope extends to 272 x 206.77 x 555.05 mm.[1]
The DSD provides a CubeSat Release System for low-velocity separation and an Umbilical Disconnect System that maintains communication and power to the payload during transit.[1] Release speed is 3 cm/s, configurable per mission requirements.[1]
The DSD project page lists a programme initiated with ESA and OHB in 2019, with hardware delivery in 2021 and a 2024 target launch date.[2] Independent agency or peer-reviewed technical sources for the public specification were not identified; the ISISPACE operator product and project pages are the primary sources as of 2026-05-28.[1]
