NanoAvionics to provide 12U bus to NASA


(01 May 2022) NanoAvionics has been selected to build a 12U nanosatellite bus for an in-orbit demonstration of NASA's Advanced Composite Solar Sail System (ACS3). This a result of a contract between NASA Ames Research Center and AST for a 12U bus to carry NASA's payload into low Earth orbit (LEO) including an approximately 74 square meter composite boom and solar sail system.

The aim of the ACS3 mission is to replace conventional rocket propellants by developing and testing solar sails using sunlight beams to thrust the nanosatellite. These solar sail propulsion systems are designed for future small interplanetary spacecraft destined for low-cost deep-space and science missions requiring long-duration, low-thrust propulsion.

With already more than 75 successful satellite missions and satellite-related commercial projects, NanoAvionics will assemble the 12U bus at its new Columbia facility in Illinois, while the final integration of the payload will be carried out at NASA Ames facilities. Matching NASA Ames' mission requirements, the 12U bus shares the same flight-proven subsystems as NanoAvionics' flagship M6P bus but with up to 10U payload volume. The larger volume will be necessary to provide enough room for the 4.6 kg payload that includes the composite boom and solar sail system as well as cameras to monitor the solar sail during and after deployment.

As part of this agreement the company will also supply a mechanical testbed model and a FlatSat model. In addition, a team of NanoAvionics engineers will provide the support required for testing, integration and operations of the nanosatellite.

The FlatSat model has identical software functionality as the final 12U bus hardware, hosting the actual payload. It allows NASA Ames to run tests via remote network connectivity without having to ship equipment back and forth. The mechanical testbed model can be used for testing payload integration and other mechanical tests, such as the deployment of solar sails.
