The PSEMU-01¹ is nearing its final stage of development, with all assemblies and subsystems having a working prototype it had its first SIT². This marks a significant milestone in the development of this next-generation spacesuit and brings us one step closer to exploring the surfaces of other planets.
The PSEMU-01 is a highly advanced spacesuit designed to enable our astronauts to walk on the surfaces of other planets. It is designed to be lightweight, durable, and capable of withstanding the harsh environments that astronauts will encounter on these planets. The SIT process ensures that all the components of the spacesuit are properly integrated and working together as a single system.
Ensuring astronauts stay connected
During this first SIT several important checks were carried out to ensure that the PSEMU-01 is functioning as intended. One of the key checks performed was a communications check, which involved testing the spacesuit’s communication systems to ensure that they are able to connect with other spacesuits.
Testing life support systems
In addition to this an LCG³ & LCS⁴ integration check was performed, which involved measuring the cooling potential of the LCS & LCG combined. Astronaut Kurpershoek did several exercises in a space heated to 35°C to test if the LCS is able to sustain astronauts on extended missions.
Testing mobility
Finally, a Range of Mobility check was carried out to ensure that the PSEMU-01 provides astronauts with the necessary range of motion to carry out a variety of tasks on the surface of other planets. The test consisted of a series of squats and bends while wearing the spacesuit to ensure that they are able to move comfortably and easily. This test would help to determine if the spacesuit provides enough flexibility in the leg and knee joints. The astronaut had to perform tasks that involve the use of tools while wearing the spacesuit. This tests the dexterity in the hands and fingers to manipulate tools effectively. This is crucial for allowing astronauts to move around and perform experiments and collect samples while wearing the spacesuit.
Next steps
While the first SIT phase is complete, there is still a second phase to be completed before the PSEMU-01 is ready for use on a mission. This next phase will involve further testing and validation to ensure that the spacesuit is fully operational and meets all the necessary requirements for use on a planetary surface mission.
