Sidus Space and Maris‑Tech Achieve Integration Milestone for LizzieSat‑4 Mission

Sidus Space, Inc., (NASDAQ: SIDU) ("Sidus" or the "Company"), an innovative space and defense technology company, today announced the achievement of an integration milestone with Maris‑Tech Ltd.,(NASDAQ: MTEK, MTEKW) a global leader in video and AI‑based edge computing technology, as Maris‑Tech's advanced payload is scheduled to fly aboard Sidus' LizzieSat‑4 (LS4) mission, expected to launch later this year.

This milestone marks the transition from planning to active integration, as Sidus and Maris‑Tech prepare to initiate testing of Maris‑Tech's payload hardware next week. Upon completion of initial testing, the payload is expected to be integrated onto the LizzieSat-4 satellite, advancing both companies toward flight readiness.

“This integration milestone represents a critical step as we prepare LizzieSat‑4 for launch later this year,” said Patrick Butler, EVP, Engineering & Programs at Sidus Space. “Beginning payload testing and progressing into full hardware and software integration underscores the maturity of the LizzieSat platform and our ability to support advanced customer technologies from ground testing through on‑orbit operations.”

Maris‑Tech's payload is designed to demonstrate high‑performance edge computing and video processing capabilities in orbit, leveraging the modular LizzieSat architecture and Sidus' flight‑proven subsystems. The mission is expected to support real‑time data handling and advanced analytics use cases for space and defense applications.

“Entering the payload testing and integration phase with Sidus marks an important technical milestone for Maris‑Tech,” said Israel Bar, Chief Executive Officer of Maris‑Tech. “Flying aboard LizzieSat‑4 is intended to enable us to validate our edge computing and video processing capabilities in a space environment, and demonstrate seamless integration with the LizzieSat hardware and software platform as we advance toward on‑orbit operations.”

LizzieSat‑4 is part of Sidus Space's growing constellation of multi‑mission satellites engineered to support rapid payload integration, flexible hosted payload configurations, and efficient transitions from ground testing to on‑orbit operations. The mission highlights Sidus' capability as a turnkey space platform provider for commercial and government customers.
