NASA Astronauts Harvest Delicious Space Vegetables, Sans Soil
Earthly space travelers have been trying to perfect orbital botany for a while now. Stable, sustainable off world agricultural practices are needed to make longer term exploration missions possible, and though the International Space Station (ISS) has seen a few successful low-orbit gardening endeavors, all have used some sort of soil or soil-replacing growth media.
Now, thanks to NASA Flight Engineer Jessica Watkins, that could be starting to change. According to a NASA blog published last week, Watkins has begun to harvest radishes and mizuna greens aboard the ISS — grown without any soil whatsoever.
Growing any edible plants in space is always exciting, but using dirt-like growth materials presents potential resource, mess, and sanitation problems. And that’s why Watkins’ triumphant soilless crop could be a thrilling step towards a new age of interstellar discovery.

The U.S. government discouraging the opening of new mines is duplicating the problem that Europe had with energy and Russia. (It takes 10 years to get a new mine approved in the U.S.)

Intergalactic Viral Video Takes Viewers To ‘Edge’ of Universe and Blows People’s Minds
“So fascinating and yet scary how unfathomably vast space is,” comments a user.
A marvelous animation takes those who view it on an illuminating adventure through outer space, beyond the Milky Way and ultimately to the edge of the known universe. Included in the journey are stunning revelations about the difficult-to-comprehend nature of distances measured in light years.
Time crystals: the search for a new phase of matter
Pedram Roushan, from Google’s Quantum AI team in California, describes this elusive form of matter – and how it could be simulated on the company’s Sycamore quantum processor.
With their enchanting beauty, crystalline solids have captivated us for centuries. Crystals, which range from snowflakes to diamonds, are made up of atoms or molecules that are regularly arranged in space. They have provided foundational insights that led to the development of the quantum theory of solids. Crystals have also helped develop a framework for understanding other spatially ordered phases, such as superconductors, liquid crystals and ferromagnets.
Periodic oscillations are another ubiquitous phenomenon. They appear at all scales, ranging from atomic oscillations to orbiting planets. For many years, we used them to mark the passage of time, and they even made us ponder the possibility of perpetual motion. What is common between these periodic patterns – either in space or time – is that they lead to systems with reduced symmetries. Without periodicity, any position in space, or any instance of time, is indistinguishable from any other. Periodicity breaks the translational symmetry of space or time.
History In Making! Chinese Space Station ‘Tiangong’ Aims To Outdo The ISS & Have The Most ‘Precise Clock’ In Orbit
China is set to make history when it finally completes the construction of its Space Station ‘Tiangong’ and makes it operational this year.
It will be the only country to have its own space station and perhaps the only one in the world after the International Space Station (ISS) retires sometime at the end of this decade.
