Successful PGT test campaign
The test campaign is part of the dissertation of Aileen Rabsahl, a scientist working intensively on the development of the remote link between the planned lunar station, LUNA and GSOC. Rabsahl developed special test procedures using the new ODF authoring tool “Skytek” and designed two customized PGTs for the moon that could be assembled using 3D printing. These were tested under the specific lunar lighting conditions of the LUNA Analog Facility. The aim of the tests was to optimize future EVA operations and collect valuable data for the further development of lunar missions.
The test campaign is part of the dissertation of Aileen Rabsahl, a scientist working intensively on the development of the remote link between the planned lunar station, LUNA and GSOC. Rabsahl developed special test procedures using the new ODF authoring tool “Skytek” and designed two customized PGTs for the moon that could be assembled using 3D printing. These were tested under the specific lunar lighting conditions of the LUNA Analog Facility. The aim of the tests was to optimize future EVA operations and collect valuable data for the further development of lunar missions.
The tests focused on three key areas:
- the cooperation between the Columbus Control Center Col-CC, the LUNA Control Center LUCC and the Microgravity User Support Center MUSC
- the optimization of PGT operations during lunar EVAs and
- the evaluation of video and voice delays in communication.
The emphasis was placed on testing new hardware components, such as different EVA headset variants, and the use of the new Flex consoles in LUCC and MUSC. Special voice loop training for the GSOC team helped to prepare them for realistic operating conditions.
The tests focused on two PGTs specially developed for lunar conditions, which were used in combination with Atlas EVA analog suits and two remote-controlled cameras. These cameras were operated by the K13 team at Col-CC (at GSOC in Oberpfaffenhofen), while communication between Col-CC and MUSC was ensured via EUROCOM systems. The tests were intended to evaluate and optimize the communication systems under realistic conditions.
The two-day campaign included demanding tests, including operations in complete darkness to test the performance of the night vision cameras and remote control. The MUSC team repeated the tests to obtain comparable and consistent data.
Overall, the test campaign was a great success. The knowledge gained will now be incorporated into the further planning of the LUNA program, with the aim of enabling sustainable operations on the Moon. Aileen Rabsahl, who is leading the project, summarizes: “Every finding from this campaign contributes to improving the safety and efficiency of future lunar missions.” The successful collaboration between GSOC, EAC and MUSC underlines the importance of cross-site cooperation in the space sector.
