There is a lot of talk about artificial intelligence at the moment, but in space travel, AI is still in its infancy. A German satellite in space is supposed to change that.
Germany’s space engineers could hardly have found a more musical name: SONATE is the name of their satellite. This name is also an abbreviation for SOlutus NAno Satellite – an unbound, free, independently operating mini-satellite.
Because that’s exactly what it’s about: SONATE-2 is designed to operate without human intervention and rely entirely on AI for its mission.”SONATE-2 is about the size of two shoe boxes,” explains Hakan Kayal,the head of the Interdisciplinary Center for Extraterrestrial Sciences at the University of Würzburg. The satellite has two fold-out solar panels and four deployable antennas.
What is water?
Visually, what the aerospace engineer describes doesn’t lookvery impressive. It’s the software and hardware that make SONATE-2 special.This includes eight cameras. “These cameras look towards the earth and record different regions that we have previously defined,” says Kayal .”We want to use these recordings to train the AI on board.”
The scientists laid the foundation for this training on Earth, before the launch: The SONATE-2 software was taught which landscape formationslook like what. “What water is, what is not water, what reflections are and how snow differs from clouds – all of this has already been pre-trained.” Oleksii Balagurin from the University of Würzburg’s aerospace informatics department was responsible for this. He is the projectmanager of SONATE-2. “We want to use our AI to distinguish between earth, water and clouds, for example.”
The AI of SONATE-2 can now do that. Now it’s off into Earth orbit. There it will apply the knowledge it has learned and show what it has learned. “The goal is to detect anomalies,” says scientist Kayal.To do this, the AI has learned what the Earth looks like. “If its cameras discover something that the AI doesn’t yet know, it will be detected as an anomaly.”
In search of anomalies
The satellite’s cameras look down and compare what they see on the ground with what they have learned on the ground. If something doesn’t match, SONATE-2 will pay attention to certain objects. These could be, for example, circular irrigation devices, ie systems with geometric shapes.
“We taught the AI what a desert is – and if a round irrigation system appears in it, the system should be able to recognize it as an anomaly,” explains Kayal. Anomalies could also be an oasis in the middle of the savannah or cracks in an ice sheet.
The Federal Ministry of Economics is funding SONATE-2 with 2.6 million euros. The plans are even more ambitious: in the future, this AI inspace will be expanded to other planets or moons in the solar system. In a next step, SONATE-2 will turn its cameras away from the Earth and instead look out into the solar system. Because who knows what kind of anomalies are there -whether circles, triangles or lines. These include formations that have arisen due to geological activities, just like on Earth. But biological or biochemical activities can also produce geometric shapes.
Are we alone in space?
Ultimately, the next generation of SONATE satellites could even help answer the question of whether we are alone in space – or at least in the solar system. “It is conceivable that artifacts will be discovered in the solar system that are not of human origin,” believes Kayal. “It may be that alien spacecraft flew past a long time ago, perhaps landed or crashed,or parts of them could be present in the solar system.”
And then they should still be there, so the thinking goes.”It could be that with the technology we are now testing, such potentially artificial artifacts can also be recognized.” Because for AI, extraterrestrial technology would not be unusual: it would just be another anomaly.
SONATE-2 successfully launched
On Monday, SONATE-2’s journey began on board a “Falcon9” rocket, and analyses are beginning on the ground. Project leader Balagurin and his team will receive the data from space on the Hubland campus of the University of Würzburg. “We are in the hot phase in which we simulate SONATE-2 flying over Germany.”
The satellite will be accessible for ten minutes three times a day. “In these ten minutes we have to upload our daily schedule and download the data from experiments.” Then it will soon become clear what the extraterrestrial AI can do.
