Long wait for food, shortage of fresh food and water scarcity. These are some of the common problems faced by the displaced people living in refugee camps. Same is the case in relief camps set in places hit by natural calamities like flood, earthquake, drought etc. The previous article was about “Controlled Environment Agriculture”. In this article, you will read about an interesting project called “MEPA” which intends to solve food challenges on earth, especially in refugee camps using CEA technologies.

A scenario shown in the above figure is too challenging to be realised. In future human space exploration missions, our astronauts will face many food challenges when visiting exotic places like the Moon and Mars. Luckily, space engineers and scientists are working on technologies to solve the challenge of growing fresh food in space. In this article you will read about such technologies and understand how farming in space will be really done.

Melodious Sounds From a 3D Printer

Anyone can print out a photo of a whistle at home with a classic inkjet printer. But no sounds can be elicited from this image. That is left to one’s own imagination. To create a three-dimensional, functional product, a different printing process is needed. 

Even those who do not follow on engineering and manufacturing techniques have probably heard or read something about “3D printing”. But what exactly does “3D printing” mean?

“There is no comfortable path that leads from the earth to the stars”, this was already known by the Roman philosopher and naturalist Lucius Annaeus Seneca (ca. 4 BC – 65 AD), also known as Seneca the Younger.

For our journey to the stars, we have been working towards this event for almost two years with our FORAREX project: The Launch Campaign at the European Space and Sounding Rocket Range (Esrange) at the civilian balloon and rocket launch site near Kiruna in northern Sweden. It is the highlight of the German-Swedish student programme REXUS/BEXUS, which we have already presented here on the Science Blog.

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…

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?

FORAREX – Astronaut in Miniature Form

How a Single-Celled Organism Finds its Way From the Sea Into Outer Space

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 – A Hard Shell With a Soft Core

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.

Changing Language Through “Gendering”: A Hand-Picked Selection of Artists Livened up Festival Visitors 

Or where are all the non-cis men again when it gets fun?

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.
