Tim Oerther
Background in electronics engineering, He joined OPS-SAT-1 in 2023 doing mission planning, spacecraft operations and FPGA experiments. Currently responsible for the experimenters and establishing concepts for experimentation.

Nuno Carvalho
Background in systems engineering and computer science, joined the OPS-SAT team in 2024 doing mission operations and experiments support. Currently working on preparing services for the upcoming missions focusing on software.

Samuele Malta
Background in space engineering and optical systems. EGT in the OPS-SAT Space Lab since November 2024, following the development of the optical systems onboard OPS-SAT VOLT and Oriole, with a focus on pointing, acquisition and tracking.

Marzieh Najafi
Telecommunications engineer with a background in optical and free-space communication systems. Postdoctoral research fellow at ESOC since June 2024, shared between the OPS-SAT Space Lab and OPS-GSO. She works on ground-based optical technology systems, focusing on free-space optical communications, quantum key distribution (QKD), and atmospheric channel characterization, supporting OPS-SAT VOLT and Oriole.

Maximilian Henkel
Background in information and communication engineering - joined OPS-SAT mission in 2015 at Graz University of Technology, and supported designing, building, testing, and operations of the spacecraft with a focus on its reconfigurable processing platform (FPGA). Supports OPS-SAT Space Lab in employing the developed operational concepts in this new mission.

Dominik Marszk
Software engineer with background in electronics engineering (FPGA/ASIC) - joined OPS-SAT in 2016. Responsible for ground infrastructure as a whole, managing DevOps processes.

Astrid Christine Zieritz
Studied Cybernetics and Robotics with space systems as main profile. EGT in OPS-SAT Space Lab since September 2025. Working on software, environments, and other tasks to support experiments and experimenter testing, focusing on OPS-SAT PRETTY. Redesigning the OPS-SAT web page.

Dogan Kacmaz
Background in astronautical engineering with a focus on spaceflight mechanics and rocket propulsion. Joined the OPS SAT team in 2026 and supports the mission by coordinating experimenters and contributing to experiment integration and mission planning.

Tristan De La Cruz
Studied Computational Engineering Science and Aeronautics and Astronautics with focus on embedded systems, software and operations. Intern in OPS-SAT Space Lab since March 2026 supporting ground and in orbit testing for FPGAs and Software Defined Radio experiments on OPS-SAT PRETTY.
