Nebula comes with Terran Orbital’s standard microsat EPS architecture and builds on the entire product line of satellite buses and common modules for avionics and GNC algorithms. The reaction wheels on this platform have been sized to allow the spacecraft to maintain agility, and the bus is designed from the ground up to be compatible with rideshare requirements.

Nebula supports commercially available custom payloads, and easily accommodates those with odd shapes. It includes a propulsion system ideal for phasing a constellation into its mission orbit, station keeping, and disposal. The previous-generation Nebula bus, called Zuma, was used to fulfill the bus requirement for the Space Development Agency’s Tranche 0 Transport Layer.

Terran Orbital employs top-of-the-line automation and modern manufacturing processes to support the delivery of hundreds of buses annually. From order to launch, in quantities from one to a constellation of one hundred, Terran Orbital accelerates the delivery of mission solutions.
