AI Summary

Laboratory‑grown neurospheres, clusters of neural stem cells, were launched to the International Space Station in early 2024 to study the effects of microgravity. The ISS experiment exposed the cells to the space environment for an unspecified duration. After the experiment, the return trip of the sample was delayed multiple times because of adverse weather conditions at the landing zone. The delayed return meant the cells were exposed to additional time in transit before re‑entry. No further details about the cells’ condition or subsequent analysis are provided.
