In brief
- SpaceX CRS-35 launches from Cape Canaveral Space Force Station carrying four NASA biological investigations to the International Space Station.
- Lab-grown brain organoids will spend five weeks in orbit and return for comparison with identical Earth-based tissue models.
- The MVP Plant-02 crop study will infect matched space-grown and Earth-grown plants with a disease-causing fungus.
- The GEARS antibiotic resistance investigation will return to the station for its fourth and final planned visit, with astronauts swabbing surfaces to track microbial populations.
- The mission will be the first operational test of a compact microplate reader (roughly the size of a hardcover book) that reached the station earlier in 2026.
SpaceX's thirty-fifth Commercial Resupply Services mission for NASA, designated CRS-35, will lift off from Cape Canaveral Space Force Station in Florida carrying four biological and physical science investigations bound for the International Space Station. Inside the Dragon capsule, the payloads share a volume no larger than a refrigerator shelf.
At Cape Canaveral, technicians prepared four separate experiment packages for the flight, each from NASA's Biological and Physical Sciences Division. The studies examine human brain tissue in microgravity (the near-weightlessness of orbital flight), crop disease off the planet, a portable laboratory device for in-orbit diagnostics, and the evolution of antibiotic-resistant bacteria aboard the station.
What happens to the human brain in orbit?
The first study, called Avatar Organoids, sends lab-grown models of human brain tissue (neural organoids) to the station for five weeks. Investigators will compare the space-flown tissue against identical models kept on Earth to determine how a short mission alters cells at the neural level.
NASA has described the work as preparation for crews bound for the Moon and beyond. Countermeasures (protective medical or behavioral interventions) for brain health during long-duration missions may follow from the cellular data the experiment returns.
Do crop diseases worsen without gravity?
The MVP Plant-02 investigation asks whether crop disease develops faster and more severely in microgravity. Scientists will infect matched Earth-grown and station-grown plants with a disease-causing fungus, then track the molecular and structural differences between the two groups.
The agricultural question carries operational stakes. Crops grown on a future Mars base will provide nutrition, absorb carbon dioxide, release oxygen, and recycle water. Disease-resistant plant lines bred from these data could reduce yield loss both in orbit and on Earth.
Can infections be diagnosed without sending samples home?
The flight carries the first operational test of a compact microplate reader — a benchtop device roughly the size of a hardcover book — that reached the station earlier in 2026. Under the Commercially Enabled Rapid Space Science initiative, the crew will use the instrument to measure biomarkers (biological indicators such as antibodies, antigens, and proteins) directly on board.
The current method requires frozen samples to ride a Dragon back to terrestrial laboratories, often months after collection. On-board detection, NASA researchers have noted, could shorten that timeline to hours and prove essential in deep-space settings where resupply and medical evacuation grow unreliable.
How do superbugs change in microgravity?
The GEARS study — Genomic Enumeration of Antibiotic Resistance in Space — returns to the station for its fourth and final planned visit. Astronauts will swab station surfaces repeatedly, building a multi-year genetic record of microbial populations.
Microgravity, closed ventilation, and the immune effects of spaceflight together create a venue for studying bacterial resistance. The resulting catalogue, NASA has stated, could inform protective protocols for astronauts on long missions and offer a closed-system model for how resistance emerges from heavy antibiotic use on Earth.
All four investigations share a methodological hinge. Each compares a space-flown sample against an Earth-based control. The question runs the same in every case: what does a familiar biological process look like when gravity disappears from the variables?
Five weeks after launch, the Dragon will return to Earth carrying frozen samples from all four investigations.
