Installing NEMUCO In BioLab On The International Space Station

ESA Astronaut Sophie Adenot: Day 122, orbit 1892 — In this timelapse, I’m installing the European NEMUCO experiment in the BioLab facility of the Columbus laboratory module. Delivered by the CRS-34 cargo mission, NEMUCO explores how nerve and muscle cells develop and communicate in microgravity, compared to samples on Earth.

Without countermeasures – like two hours of daily exercise – astronauts’ muscles not only shrink but also lose strength and coordination. NEMUCO investigates, at the cellular level, how microgravity affects the formation of connections and stability between nerves and muscles, known as neuromuscular junction (NMJ). These are crucial for providing functional muscle!

Understanding these changes will help protect astronauts’ health on future missions and could also support improved therapies on Earth for rehabilitation, aging, and neurodegenerative neuromuscular diseases.
