D-Start

d-start designs and manufactures engines with external energy sources for single-pulse orbital maneuvers of femto-class spacecraft, as well as a family of related technical solutions. The company aims to economically use space debris and technological waste as energy sources for its engines. They have developed and manufactured experimental equipment, selecting materials with high gasification rates for engine active targets. The functionality of these solutions has been confirmed in conditions identical to open space, and a series of ground tests have been successfully completed. Flight tests were planned for 2021-2022. d-start focuses on propulsion systems for pico- and femto-class spacecraft, including ChipSats, with a mass of 100g or less. They offer complete engines, components for self-assembly, design services for maneuvers, and licenses for their technology and materials. Their product lines include solar thermal sublimation and thermocatalytic engines "Impulse-S" and "Impulse-TS," and high-thrust single-pulse engines "Impulse-A," along with an educational version "Impulse-U." The company has conducted launch tests of femto-class spacecraft mock-ups with "Impulse-S" engines. They are developing the "Impulse-A" engine line with international partners (India) for external and internal markets, and the "Impulse-U" line for educational spacecraft. d-start targets private and government developers, buyers, and users of ultra-small spacecraft, as well as scientific and educational organizations. They hold a patent for a thermobaric chamber for thermal vacuum testing of engines for ultra-small spacecraft. The company is a resident of the Skolkovo innovation center, the Zhigulevskaya Dolina technopark, and the NPC BAS in Tomsk. Their projects have been recognized as finalists in the Sky.tech national innovation project competition in 2021 and 2023. The company's equipment is used in educational projects, such as "Cheburashka" at the Omsk Quantorium.
