The ‘Internet of Animals’ is about to change our understanding of nature

Tracking and documenting life on our planet

To gather data for the Internet of Animals, tiny solar-powered tracking devices are attached to a breadth of living organisms and natural landscapes including glaciers and ocean plastic. Some of these devices weigh even less than a paper clip.

The tags track thousands of animals to uncover how their experiences link to broader global changes such as environmental shifts, variables that lead to species decline or migration, and much more.

Transmitting the data to space satellites, these inexpensive and easy to deploy trackers will paint a detailed picture of the ongoings of various animals and environments around the world. It will help scientists develop a rich understanding of trends and patterns, as well as what is driving global change.

The benefit of using trackers lies in the real-time updates and timelines they offer. Scientists won’t have to rely solely on observations they make while out in nature doing field research, they’ll be able to consult a database to understand where the animals are or will be.

In fact, the project was already providing this service before facing challenges caused by geopolitical tensions.

ICARUS’ series of starts and stops

If all goes to plan, five low-cost satellites carrying ICARUS receivers will be launched into space via a private rocket next year. This won’t be the first attempt to get the project (literally) off the ground, though.

Back in 2018, the project’s team launched a receiver destined for the International Space Station on a rocket from Kazakhstan. Upon its arrival, Russian space experts attached the receiver to its orbiting lab.

A successful launch meant the Internet of Animals was in action for a short time in the springtime of 2020, but mechanical complications at the Russian space lab caused signals to drop out for almost a full year.

In 2021, the system was back up and running again, tracking 3,500 animals around the globe. Once again, the signal was short-lived. Russia’s invasion of Ukraine caused the West to slash ties with Russia, resulting in all data transmission from ICARUS going dead.

After numerous let-downs, conversations with private launch companies, and lots of innovation, the team at ICARUS have decided to re-launch five different satellites called CubeSats to transmit data to and from their trackers. CubeSats are miniature satellites that look like Rubik’s cubes and weigh just a few kilograms.

This will be no cheap endeavour, costing around $1.57 million USD for the launch alone. Luckily, the funding is coming from the Max Planck Society, an independent non-governmental and non-profit association of German research institutes. Each year, operating expenses for the CubeSats will cost just over $150,000.

Using private companies to launch ICARUS’ receivers was a tactical choice.

Involving the International Space Station in operations requires consultation and permission from national governments, opening the door to potential geopolitical hurdles that could cease the operation – for example, when Russia’s war in Ukraine resulted in the satellites turning off in 2021.

Not to mention, the new receivers will present better global coverage. The receivers placed on the ISS weren’t able to transmit data from tags placed in high altitudes on Earth. So I guess it’s a win-win for the team at ICARUS.

What is the value of the ICARUS project?

The Internet of Animals is a cool concept, but most importantly, it will improve accessibility, accuracy, and information detail for scientists researching our planet.

The project has been described as ‘levelling the playing field in studying the earth’ by providing high-quality information that is accessible to everyone. That includes major organizations, smaller teams, or individuals with small budgets or obscure research subjects.

Scientists involved in ICARUS believe the data will also be able to better inform climate models. By gathering intel from areas that have been historically challenging to monitor, such as the sky, ocean, or ice, experts can understand how these areas are being affected by human pressures.

Conservation strategies will also benefit, thanks to the pinpoint technology of trackers. Satellites will pick up the precise coordinates of areas seeing the most change, while providing information about the location’s air pressure, altitude, temperature, and humidity.

Finally, the knowledge provided by the ICARUS project could inspire people everywhere to act. If we understand the direct causes of species decline, sudden migration, or changed behaviours, we’ll be better informed on changes we can make to prevent those things from happening.

Through to 2026, Wikelski and his team plan to tag as many as 9,000 additional animals across Europe. If the 2025 launch is successful, the Internet of Animals could one day be the most important and comprehensive real-time database for the natural world that we have.
