SpaceX's CRS-35 cargo flight takes lab-grown brain models to the space station
NASA will send four biology studies to the space station on SpaceX's 35th resupply flight, including brain tissue models flown for five weeks. NASA ties the work to astronaut health on long missions, but the readouts are mostly from tissue, plants and station surfaces.
The Scientist · Science desk
What happened
- Researchers will compare the flown brain tissue models with identical ones kept on Earth to see how a short spaceflight affects the human brain at the cellular level.
- The crop study compares Earth-grown plants with station-grown plants, both infected with a disease-causing fungus, looking at molecular and structural changes.
- The flight also carries the first test of a compact microplate reader that arrived at the station earlier this year.
- The antibiotic-resistance investigation returns for its fourth and final planned stay to study how resistant bacteria survive and evolve in microgravity.
Why it matters
- What's now possible capability A reader that works would let infection screening run where resupply is hardest, the setting NASA names for the work.
- What's now possible capability A result from the fungus comparison could be used twice, NASA says: to breed disease-resistant crops on Earth and to limit yield losses in future space farming.
- What it limits constraint Because the fourth stay is planned as the last, what the surface sampling can say about evolution in microgravity will rest on a bounded set of stays.

Two of the four investigations are described with an Earth comparison group: the brain models and the crop plants [12]. That arrangement lets a difference be pinned on flight and not on how the samples were prepared. The other two ask different questions. One tests whether a plate reader can detect and measure biomarkers such as antibodies, antigens and proteins [8]. The other has astronauts repeatedly sample surfaces to monitor for drug-resistant organisms [11].
The crop study asks whether diseases develop faster and more severely in microgravity [5]. The brain study carries a softer promise. NASA says it could deepen understanding of how the human brain responds to stress and help lay groundwork for methods that counter risks on future missions to the Moon and beyond [13]. The thing this doesn't tell you is whether a cell-level change in a tissue model predicts anything about an astronaut's cognition. We think that gap is the main limit on treating the result as crew-health data.
The plate reader targets a delay. It would let scientists analyze samples aboard the station and get data quickly instead of waiting for the samples to return to Earth [9]. We think it is the investigation most likely to change how the station works, provided its readings agree with ground laboratory results.
NASA says the bacterial work could help develop ways to protect astronauts against infection during long-duration missions [17] and, on Earth, give insight into how superbugs develop from antibiotic overuse [16]. NASA's descriptions did not disclose sample counts, the crop species or fungus used, how many surfaces are swabbed, or how plate-reader results will be checked against ground laboratory results.
What to watch
- Whether investigators publish sample counts and the first plate-reader results alongside ground laboratory measurements.
- Results from the brain-model comparison of flown tissue against the Earth-kept set, once the models return.
- Whether another stay of the bacteria investigation is scheduled after the fourth planned stay.
