Fifty-One Students Sent a Shrimp Aquarium to the Space Station

On 13 October 2026 at 12:33 CEST, a SpaceX cargo mission lifted off for the International Space Station carrying an unusual passenger: a student-built Shrimp Aquarium. According to the European Space Agency, the SCAMPI experiment payload was conceived, designed, built and tested by 51 university students drawn from institutions across Europe and the United States. Its mission is to find out how a closed aquatic ecosystem — shrimp, algae and microbes sealed together in a small habitat — behaves when gravity is taken out of the equation. NASA said the Dragon carried more than 6,300 pounds of supplies and experiments to the station on this flight.

Once the hardware is plugged in aboard the station, students and young researchers will monitor it remotely and collect data on how microgravity shapes the interactions between the system's living and non-living components, ESA said. The project is part of the agency's student experiment programme, which gives university teams the chance to fly real science on real missions rather than just study it in a classroom.

A late-load payload with living passengers

SCAMPI counts as what engineers call a late-load payload: because its cargo is alive, it cannot be bolted into a rocket weeks in advance and left sitting on the pad. In the days before liftoff, the student team worked at Kennedy Space Centre to refresh the sealed ecosystem, inspect the tanks, verify the health of the organisms inside and confirm the payload was in its flight configuration, all under the supervision of the agency's payload integration manager. Once those checks were complete, the hardware was handed to NASA counterparts for launcher integration and the ride to orbit.

After docking, an astronaut will install the unit in the ICE Cubes Facility, a commercial research service located inside Europe's Columbus module. From that point on, the crew steps back and the students take over. Once installed, the Shrimp Aquarium runs itself: no crew attention is needed, and all monitoring and data collection happens from the ground. It shared the ride with a packed manifest — the same flight also delivered the station's final solar arrays and lab-grown heart tissue. That division of labor is part of what makes the project unusual: instead of astronauts tending an experiment between other duties, a student team gets a remote-run laboratory in orbit, with the crew's main contribution being the installation itself.

Why a tiny sealed world matters

According to the team's own communications channel, the habitat holds three Hawaiian shrimp, an alga and roughly 16 million microbes, all expected to keep going for 90 days without any help from the crew. It is a deliberately spare recipe: a simple food web with producers, consumers and decomposers, sealed inside a habitat and left to balance itself.

The stakes go well beyond a curiosity in a glass box. Closed ecological systems could one day recycle air and water aboard long missions far from Earth, the kind of life support that sustained Moon bases and future Mars journeys will require. ESA said the data from SCAMPI will feed research into future life-support systems capable of supporting human exploration of the Moon, Mars and beyond. Most earlier space biology research has studied single organisms in isolation; sending an entire multi-level ecosystem, from microbes to crustaceans, puts the focus on how the parts interact as a system under weightlessness.

The mission does not end when the in-orbit work is done. The payload is expected to return to Earth, where students will carry out genetic and biological analyses on the flown samples and compare them with ground-based controls kept under ordinary gravity. That comparison is where the science lives: differences between the two sets will show how prolonged weightlessness reshaped the ecosystem at the molecular level. A report on the launch notes the team considers the return leg and lab work as central to the mission as the flight itself.

The students behind the launch

The consortium was co-led by Politecnico di Torino and École Polytechnique, with partner institutions in France and the Netherlands also involved. Supported by the academy programme and its partners, the team completed the reviews, tests and qualification activities required for launch, gaining hands-on experience with the technical and operational demands of a real spaceflight project. Getting a biology payload cleared to fly on a crewed station is no small feat: every material, seal and failure mode must pass scrutiny designed to protect the crew, and the students navigated that process themselves. Other young engineers are aiming at orbit too — a startup recently outlined plans for satellites that think in space.

"SCAMPI has given students the opportunity to take on a real-world challenge," said Sabrina Corpino, a professor of aerospace systems at the Turin university, calling the effort an "invaluable learning experience" that will also inform future regenerative life-support research. Details of the launch are laid out in ESA's launch announcement.

For the students watching from the ground, the months ahead will mean telemetry streams, data plots and biology reports instead of lectures. If the sealed world survives its time in orbit and the post-flight analysis yields clean comparisons, the team will have done more than build a clever student project — it will have handed future deep-space mission planners real data on how living systems cope with life beyond gravity.
