Wireless power from space

Posted by in categories: business, government, solar power, space, sustainability

Solar power gathered far away in space, seen here being transmitted wirelessly down to Earth to wherever it is needed. ESA plans to investigate key technologies needed to make Space-Based Solar Power a working reality through its SOLARIS initative. One such technology – wireless power transmission – was recently demonstrated in Germany to an audience of decision makers from business and government.

The demonstration took place at Airbus’ X-Works Innovation Factory in Munich. Using microwave beaming, green energy was transmitted green energy between two points representing ‘Space’ and ‘Earth’ over a distance of 36 metres.

The received power was used to light up a model city, produce green hydrogen by splitting water and even to produce the world’s first wirelessly cooled 0% alcohol beer in a fridge before serving to the watching audience.

Making Suns

Without the Sun our world would be a frozen wasteland, and for this reason any efforts to colonize the galaxy must focus on huddling in the tiny oases of warmth around stars, separated from each other by enormous gulfs of interstellar space. But what if we could make our own stars at the places of our choosing? And can we merely mimic nature or create stars unlike anything which nature has formed?

Inside NASA’s most mind-blowing Mars base designs — including inflatable homes

Posted by in categories: 3D printing, space

THE most impressive designs for near-future Mars bases have finally been revealed.

These elaborate celestial plans are the difference between human life surviving on Mars – and thriving.

When it comes to planning how to live on a planet like Mars, 3D printing has provided scientists with the easiest way of navigating an environment that has similarities, but ultimately boasts a vastly different environment from Earth.

Solar cells one-thousandth the size of human hair can resist space radiation

Posted by in categories: physics, solar power, space, sustainability

Earth’s low orbit is filling up, meaning radiation-tolerant cell designs are required as satellites head to higher orbits. Will these new ones do?

Scientists have developed a radiation-tolerant photovoltaic cell design that features an ultrathin layer of light-absorbing material. According to a new study published today (Nov .08) in the Journal of Applied Physics by AIP Publishing.

Significantly, the ultra-thin solar cells not only surpass earlier suggested thicker solar cells in resilience to irradiation; they also produce the same amount of power from converted sunlight after 20 years of use. Additionally, the novel photovoltaic cells could reduce load and considerably lower launch expenses. Barthel.

In a world first, astronomers observed a star with a solid outer surface

Posted by in category: space

“This was completely unexpected.”

Stars are essentially large fiery balls of plasma, which is often referred to as the “fourth state of matter” as it forms when gas is heated into a soup of positively charged ions and negatively charged electrons.

The star’s magnetic field is so strong it appears to have “frozen” its surface into a solid outer crust, a press statement reveals.

Two NASA Boeing Projects Expose the Failings of the Relationship

Posted by in category: space

With cost overruns and milestones not met, it is a wonder that NASA and Boeing aren’t headed for a divorce.


Agency budgetary report shows tens of billions spent on Boeing contracts that have yet to deliver. Much cheaper alternatives exist.

Scientists unveil further proof of salty water on Mars

Posted by in category: space

It may be known as a rocky, red planet but evidence is mounting that salty water exists at the base of polar deposits on Mars.

University of Southern Queensland’s Professor Graziella Caprarelli is part of an international team investigating bright reflection signals below the Martian surface, first spotted in data acquired between 2010 and 2019 by the radar sounder MARSIS on board Mars Express.

The primarily Italian team proposed that the reflections pointed to a patchwork of salty lakes, publishing their research in Science in 2018 and in Nature Astronomy in 2021. Recently a new collaboration between the Italian team and U.S.-based researchers provided new evidence further corroborating this interpretation.

This stunning timelapse reveals how the universe has changed in just 12 years

Posted by in category: space

NASA combined 18 all-sky images to create a timelapse of the night sky.


The Universe is over 13 billion years old, so a 12-year slice of that time might seem uneventful. But a timelapse movie from NASA shows how much can change in just over a decade.
