In a groundbreaking study, European researchers investigate how insects could provide nutritious food sources for long-duration space missions, continuing a legacy of insect space exploration that dates back to the fruit fly’s historic journey in 1947.

Long before humans ever left the atmosphere, insects were demonstrating their remarkable resilience in harsh environments. Their lightweight structure, adaptability, and nutritional density make them an appealing focus for European researchers who are investigating sustainable food sources for extended space missions.

The Edible Insect Revolution

In many parts of the world, consuming insects is a common practice. The UN’s Food and Agriculture Organization highlights that human beings eat over 2,000 different insect species globally. With such a massive population already embracing entomophagy (the consumption of insects), the transition to including them in astronaut diets doesn’t seem too far-fetched.

A Space Mission for Insects

The European Space Agency (ESA) has assembled a multidisciplinary team of experts to assess whether insects could someday be included in an astronaut’s meal plan. Research into insect viability in space dates back to the 1940s, and various species have been shown to withstand the rigors of microgravity without major disruptions in development.

Professor Åsa Berggren from the Swedish University of Agricultural Sciences explains, “Insects seem to cope quite well in space environments. They have a good ability to withstand physical stresses.” This observation suggests that insects are not just survivors; they’re also efficient at converting inedible materials into nutritious food, thus presenting a sustainable solution for food production in space.

Bug Orbital Hotels: A Brief History

The journey of bugs in space began with fruit flies, the first animals to be launched into orbit in 1947. These nimble insects provided valuable insights into the effects of radiation on living organisms. Since then, a variety of insects, including bumblebees, houseflies, and ants, have participated in space research, revealing both resilience and challenges.

Ants showcased an impressive ability to adhere to surfaces in microgravity, while stick insects encountered significant hurdles with mobility and reproduction. Water bears, or tardigrades, have also contributed valuable information about survival mechanisms in space.

Culinary Delights from Space

Insects offer not only a potential food source but also a culinary adventure. On Earth, they can be prepared in flavorful ways, with crickets tasting like nuts and mealworms having a resemblance to bacon. Nutritionally, they pack a punch, providing high-protein content, essential fatty acids, and important vitamins and minerals.

House crickets and yellow mealworms are especially noteworthy; both species were approved for human consumption by the European Food Safety Authority in 2023. With innovations like cricket flour making their way into foods, even astronauts are beginning to include insect-based snacks in their diets, as seen with ESA astronaut Samantha Cristoforetti’s blueberry cereal bar made with cricket flour during her 2022 mission.

The Road Ahead

Despite the promising results, the overall understanding of insects in space remains incomplete. Much of the existing data comes from older experiments, many of which were conducted decades ago. Additionally, the duration of these studies often fell short of capturing the full lifecycle of the insects involved.

To build upon this knowledge, researchers are currently designing new experiments that will explore how microgravity affects various insect species over longer durations. This research could play a crucial role in developing reliable food sources for future missions beyond Earth.

As we look toward longer missions — perhaps to Mars or even beyond — the role of our tiny, six-legged companions could become increasingly significant. With their ability to sustain life in extreme conditions and convert inedible resources into nutritious food, insects might not just be a supplement but an essential part of our future space menus.

As scientists continue to explore the potential of insects in space, it’s clear that these common critters hold extraordinary possibilities for human survival and sustainability, both on Earth and among the stars.
