Dr. Angelo Vermeulen is a space systems researcher at Delft University of Technology in the Netherlands, where he explores advanced concepts for interstellar exploration. Over the past decade, he has collaborated closely with the European Space Agency's (ESA) MELiSSA program, developing concepts for bioregenerative life support systems for space. In such systems, a variety of microorganisms progressively break down human waste and the resulting compounds are harnessed by plants to produce oxygen and food for the crew.

Beyond his scientific pursuits, Dr Vermeulen is also an accomplished artist and a co-founder of the SEADS (Space Ecologies Art and Design) collective. SEADS creates artworks that seamlessly integrate concepts and technologies from a diverse array of scientific disciplines, including biology, neuroscience, computer science, and astrophysics.

He is the author of a recently published Frontiers in Astronomy and Space Sciences article in which he and his co-authors describe a new model that theoretically produces all required food and oxygen during long-duration and remote space missions, removing the necessity for resupply from Earth.

Plenty of areas in the solar system are interesting for scientific purposes but hard to access by traditional rovers. Some of the most prominent are the caves and cliffs of Mars—where exposed strata could hold clues to whether life ever existed on the Red Planet. So far, none of the missions sent there has been able to explore those difficult-to-reach places. But a mission concept from a team at Stanford hopes to change that.

The concept, known as ReachBot, is a robot that can support itself using multiple articulated appendages to navigate terrain that would be difficult to reach using other navigational techniques. In addition to being able to traverse complex ground patterns, it could also, in theory, at least scale sheer cliff faces.

It was initially pitched as a NASA Institute for Advanced Concepts project, where it was awarded a Phase I grant back in 2021. The authors describe the idea as a fusion of two separate technologies developed for different purposes: mobile manipulation robots and deployable space structures.

Mobile manipulation robots are relatively common in space exploration.

The space industry has changed dramatically since the Apollo program put men on the moon in the late 1960s.

Today, over 50 years later, private companies are sending tourists to the edge of space and building lunar landers. NASA is bringing together 27 countries to peacefully explore the moon and beyond, and it is using the James Webb Space Telescope to peer back in time. Private companies are playing a much larger role in space than they ever have before, though NASA and other government interests continue to drive scientific advances.

I'm a macroeconomistwho's interested in understanding how these space-related innovations and the growing role of private industry have affected the economy.
