Sidus Space, an innovative space and defense technology company, announced its role as a subcontractor supporting MobLobSpace under a NASA Small Business Innovation Research (SBIR) award. The six-month design study will focus on designing and planning a mission to host an advanced space-based 4D radar system onboard Sidus’ LizzieSat satellite platform, delivering critical Space Domain Awareness (SDA) data services to track centimeter-scale orbital debris.
Under the $173,000 NASA SBIR award, MobLobSpace will develop an adaptive electronically scanned array radar as part of NASA’s Space Sustainability Strategy programs. Sidus Space will provide input on host spacecraft specifications, including power and Guidance, Navigation, and Control (GNC) systems, to ensure seamless integration of the radar payload aboard LizzieSat.
“Partnering with MobLobSpace to host advanced radar technology aboard LizzieSat represents a significant step toward improving space situational awareness and mitigating collision risks,” said Carol Craig, CEO of Sidus Space. “This collaboration positions Sidus to deliver scalable, commercially viable solutions that support the long-term sustainability of space operations.”
In addition to the design study, Sidus has received an add-on Technical and Business Assistance (TABA) award to conduct a study exploring scale pathways for the SDA data service. This analysis will examine the number of satellite nodes required for a constellation capable of complete orbital coverage and assess deployment strategies to meet growing demand for orbital debris tracking.
“Hosting an adaptive radar in orbit demands precise power and GNC integration,” said Charlton Shackleton, Co-Founder of MobLobSpace. “LizzieSat’s design provides the flexibility needed to support this capability.”
This collaboration underscores Sidus Space’s commitment to advancing space sustainability through innovative partnerships and technology integration. By leveraging LizzieSat’s versatility and MobLobSpace’s radar expertise, the project aims to deliver critical data services that protect assets and ensure safe operations in an increasingly congested orbital environment.
