Long anticipated and eagerly awaited, our student training week starts in snowy Lapland near Sweden’s northernmost city: Kiruna (from the North Sami “giron”, meaning “snow grouse”).
Bremen Airport is already getting us in the mood for the weather that awaits us in Lapland…
An European Education Programme Empowers Students to Develop Their own Space Mission

In our last article, we told you about our FORAREX project, which we developed within the framework of the German-Swedish REXUS/BEXUS programme.
But what exactly does this REXUS/BEXUS programme entail? And who can participate?

Imagine you are living under the sea. You see the suns rays shining through the water. There is sand beneath you. The water flows around you to the rhythm of the wave – and you sway with it (see Fig. 1). Everything feels very pleasant. You are thinking how wonderful your home is. The waves, the light – everything is perfect.
But suddenly a dark shadow looms over you – and this shadow takes you out of this paradise and catapults you into space! Isn’t that a disturbing and rather improbable idea?
But that is in fact my story.

Foraminifera (Latin for “hole bearers”, informally called “forams”) are single-celled organisms that usually have a multi-chambered shell, which can be built in various ways depending on the species. They are the stars of the FORAREX (FORAminifera Rocket EXperiment) project, in which we investigate their behaviour and shell growth under microgravitational conditions.

Surely, everyone has wondered how 99 Festivalbesucherinnen (female festival visitors) become 100 Festivalbesucher (male festival visitors) as soon as one man stumbles into the dancing and partying mob. Poof, all the confidently partying women are just gone.

Eatable, inedible, deadly. Tiny and of enormous size. Hardly any life form is as diverse as that of the fungi. Neither they can be called animals nor plants, they form their own taxon amongst the living organisms. Even though, they are a big part of our nutrition, we barely know how complex these organisms actually are. For example, did you know that the planets biggest living organism is in fact a fungus? Or did you know that fungi made the evolution of many life forms on earth possible by establishing complex interactions aka symbioses? Find out more about these fascinating organisms!

What do a torn ligament in the ankle joint and an air bubble in a shard from the 16th century century have in common? Both can be determined and measured non-destructively. With a computer tomograph.

The IPCC (The Intergovernmental Panel on Climate Change) published its sixth report about the latest findings about climate change and the news are full of it. Again, fundamental questions about our modern lifestyle arise, which strongly influences our environment. The IPCC-report contains most important information, but not everyone finds time to completely read through the report. In the present article we provide the most important statements of the report.

Every single person has probably imagined once what life as a superhero with special skills would be like. Of course, we all know that most of the skills that actually define superheroes are supernatural and (unfortunately) come entirely from the imaginations of the authors and filmmakers.
About Ice Cores Part III
Ice cores preserve stories of the past. Now we want to compare these stories with other history books. Illustration: Hanna Knahl
We have now already learned a lot about ice cores. We know where to find them, how to drill them and how to extract information about the past climate from them. BUT there is still one important piece of information missing. The time stamp. How do we determine how far back in time the ice we hold with our gloved hands comes from? We will see, the ice also uses special languages to encode this secret.
