Spectrum

Spectrum [Isar Aerospace]

Spectrum is a small liquid fueled orbital launch vehicle, which is being developed by Isar Aerospace, Germany.

Spectrum is a two-stage launch vehicle that is specifically designed for satellite constellation deployment. Payload capabilities of up to 1000 kg to low-earth orbit and a multi-ignition second stage engine enable flexible access to space for major satellite systems. Spectrum is designed to handle the most challenging mission parameters and offers engine-out capability on the first stage.

Spectrum has a principal diameter of 2 meter and a length of 22 meter. It uses light hydrocarbons and liquid oxygen for reduced environmental impact compared to common propellants. The engines are developed in-house. Stage 1 is propelled by a cluster of nine Aquila-SL engines. Stage 2 features one reignitable Aquila-Vac engine. Payload fairings with 1.8 meter and 2.5 m diameter are available.

A maiden flight is planned for 2022. Andøya Space Center, Norway, has been selected as launch site.
