When NASA’s Crew-11 mission rocketed toward the International Space Station in August 2025, it carried more than just astronauts and cutting-edge equipment. Nestled among the scientific payload was a collection of tiny—but mighty—seeds: seabuckthorn and Himalayan buckwheat, both indigenous to the rugged, nutrient-rich soils of Ladakh, India. This unique experiment, led by US-based bioastronautics firm Jaguar Space in collaboration with Bengaluru startup Protoplanet, is advancing both the science of microgravity and the future of sustainable food production beyond Earth.
Let’s dig into why these “super seeds” are making headlines around the world and what their journey tells us about the next chapter of space agriculture.
Why Seeds in Space Matter: Food Security and Beyond
The International Space Station has long been humanity’s orbital outpost for scientific discovery. But as space agencies plan extended missions to the Moon, Mars, and beyond, the question of how to nourish astronauts—without constant cargo deliveries—has become crucial. Traditional packaged foods degrade over time, both in quality and nutrition.
Imagine being months away from Earth and knowing a garden aboard your space habitat is your freshest food source. This is why researchers continue to test which crops can grow, thrive, and provide robust nutrition under space’s unique stresses: microgravity, limited water, fluctuating temperature, and high radiation.
Introducing Ladakh’s Superfoods: Seabuckthorn and Himalayan Buckwheat
Seabuckthorn (Hippophae rhamnoides):
Native to the high-altitude deserts of Ladakh.
Rich in omega fatty acids, antioxidants, vitamins, and minerals.
Renowned for climate resilience and ability to grow in poor soils.
Used in traditional medicine and modern health foods.
Himalayan Buckwheat (Fagopyrum tataricum, aka Tartary buckwheat):
Gluten-free, packed with protein, fiber, and bioactive compounds.
Grows at high elevations with minimal water.
Known for supporting biodiversity and local food security.
Both crops are “climate-smart”—their resilience makes them ideal for both Earth’s harsh environments and the unknowns of space.
Inside the Crew-11 Experiment
How the Seeds Reached Space
Carried as part of NASA’s Crew-11 mission, which docked with the ISS in August 2025.
Sourced by Protoplanet in Bengaluru, representing India in an international study with seeds from 11 countries. republicworld
Payload titled “Emerging Space Nation’s Space for Agriculture & Agriculture for Space,” highlighting a global commitment to advancing agricultural science for space settlements.
What Happens to the Seeds?
The seeds are exposed to microgravity for approximately one week aboard the ISS.
Scientists will later analyze their genetic and physiological responses, particularly how they survive, adapt, and potentially germinate after return.
Fundamental biological processes are under scrutiny: gene activation, metabolic shifts, and how these influences could guide future crop selection for space farming.
Why Take Seeds from Around the World?
Bringing together seeds from diverse environments isn’t just symbolic. It aims to:
Test global crop biodiversity in space conditions.
Understand how plants adapted to Earth’s extremes might fare in orbit or on other planets.
Safeguard cultural and agricultural heritage as humanity ventures into space.
The Future of Space-Based Agriculture: What’s at Stake?
Growing food in space isn’t just for astronaut nutrition—it’s about building a sustainable human presence off Earth. Successful plant cultivation could:
Reduce reliance on expensive resupply missions.
Freshen astronauts’ diets and support their health on long-duration voyages.
Offer psychological comfort, as “space gardeners” experience the color and life of living plants in otherwise sterile environments.
Advance agricultural technology back on Earth, especially in water-scarce or degraded environments.
Recent ISS Plant Experiments: Context Matters
NASA has previously grown lettuce, tomatoes, mustard, and even chile peppers on the ISS, gaining insights into light, nutrition, flavor, and plant-microbe interactions.
Each experiment adds to a growing knowledge base—what survives best, what’s most nutritious, and how to maximize yields with few resources.
The addition of Ladakh’s crops marks the first time these particular superfoods are tested in orbit, broadening our reference point for future agricultural choices.
Why This Matters for Earth
Experiments like this do more than push the boundaries of space science. They:
Offer hope for breeding more resilient, nutrition-dense crops adapted to climate change.
Foster global collaborations between nations, scientists, and students.
Preserve traditional crops and agricultural wisdom as part of our shared planetary heritage.
As humanity faces mounting challenges—population growth, changing environments, and the need to protect biodiversity—the lessons learned in space could circle back to help nourish people on every continent.
