Earth’s orbit is riddled with disused satellites and debris – a danger to the infrastructure in space. Now, the European Space Agency (ESA) has commissioned a Swiss start-up to prepare a waste disposal mission.

While Mars was the focus of space activities in 2021, many missions to the Moon will start this year. In addition, ESA is setting off for Jupiter. And NASA wants to divert an asteroid.

Earth’s orbit will soon be teeming with new satellites. Companies such as Amazon and Space X want to use them to connect even the remotest corners of the globe to the Internet. Researchers from the Swiss Federal Institute of Technology (ETH) in Zurich recently unveiled how this Internet from space could be optimized even further.

Delta robots are typically used for packaging – for example candies. Now one of these robots has made it onto the International Space Station in the form of a high-tech joystick: The system, developed at the EPF Lausanne, is designed to help remote-control exploration robots.

Using the space-based observation system Icarus, scientists want to track the movements of animals – and thus find out more about the behavior of various species on Earth.

Astronauts cannot do their laundry - and also have to share certain items of clothing with their colleagues. Austrian researchers are now investigating how microbes could be used to keep more than just underwear clean in space.

The prospect of a juicy Sunday roast in zero-gravity has just come a little closer: A Russian cosmonaut on board the International Space Station ISS has succeeded for the very first time in producing meat in space using a 3D printer.

From London to Sydney in just four and a half hours – this is the dream of the UK Space Agency (UKSA). A special propulsion system that is intended to make this flight at supersonic speed possible is targeted for the 2030s.

Travelling to the past or future is a fascinating concept: But is time travel even feasible and would it be like it has been depicted in so many movies? Philosopher and physicist Norman Sieroka provides the answers.
