Dark Dweller

Posted by in category: space travel

By Gareth Worthington is a slim book that crams in lots of classic science fiction ideas. Singularities, first contact, and sentient spacecraft to name but three. Of my recent SF reads, Dark Dweller reminds me both of James Smythe and Gareth Powell

What is Dark Dweller?

The novel opens in a future dystopia. In order to run on clean energy, Earth requires Helium. This is acquired, at no small risk, from Jupiter. The companies that run the operations are fabulously wealthy; the people that do the harvesting, not so much. The 12-year journey to and from Jupiter is hard going. You’re in suspended animation for much of it, but that gap messes up your life. But hey, it’s a job.

Nuclear Propulsion — How close are we to the Expanse?

Posted by in categories: chemistry, space travel

The future of space travel with my new YouTube video on nuclear propulsion! Learn how this technology can improve the propellant efficiency of chemical rockets, making it a viable option for crewed missions to Mars, and perhaps get us to the stars.

Plus, compare nuclear propulsion to conventional chemical rockets such as the Saturn V and to the Epstein Drive from the Expanse.

New discovery sheds light on very early supermassive black holes

Posted by in categories: cosmology, space travel

Astronomers from the University of Texas and the University of Arizona have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early universe. The discovery of the galaxy and the black hole at its center provides new clues on the formation of the very first supermassive black holes. The new work is published in Monthly Notices of the Royal Astronomical Society.

Using observations taken with the Atacama Large Millimeter Array (ALMA), a radio observatory sited in Chile, the team have determined that the galaxy, named COS-87259, containing this new is very extreme, forming stars at a rate 1,000 times that of our own Milky Way and containing over a billion worth of . The galaxy shines bright from both this intense burst of star formation and the growing supermassive black hole at its center.

The black hole is considered to be a new type of primordial black hole—one heavily enshrouded by cosmic “dust,” causing nearly all of its light to be emitted in the mid-infrared range of the electromagnetic spectrum. The researchers have also found that this growing supermassive black hole (frequently referred to as an ) is generating a strong jet of material moving at near light speed through the host galaxy.

Anti-dust tech paves way for self-cleaning surfaces

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

Dust is a common fact of life, and it’s more than just a daily nuisance—it can get into machinery and equipment, causing loss of efficiency or breakdowns.

Researchers at The University of Texas at Austin partnered with North Carolina-based company Smart Material Solutions Inc. to develop a new method to keep dust from sticking to surfaces. The result is the ability to make many types of materials dust resistant, from spacecraft to solar panels to household windows.

The research is published in ACS Applied Materials & Interfaces.

From retail to transport: how AI is changing every corner of the economy

Posted by in categories: economics, robotics/AI, space travel

The high profile race to enhance their search products has underscored the importance of artificial intelligence to Google and Microsoft – and the rest of the economy, too. Two of the world’s largest tech companies announced plans for AI-enhanced search this month, ratcheting up a tussle for supremacy in the artificial intelligence space. However, the debut of Google’s new chatbot, Bard, was scuppered when an error appeared, knocking $163bn (£137bn) off the parent company Alphabet’s share price. The stock’s plunge showed how crucial investors think AI could be to Google’s future.

However, the increasing prominence of AI has implications for every corner of the economy. From retail to transport, here’s how AI promises to usher in a wave of change across industries.

NASA Activities This Week: Naming Moon Mountain, Collecting Mars Sample; What Other Space Undertaking Makes the List?

Posted by in categories: economics, education, space travel

NASA’s mission has always been dedicated to promoting science, technology, aeronautics, and space exploration to improve education, economic vitality, environmental stewardship, innovation, and most importantly knowledge.

For the past week, the space agency has achieved a lot in exploring outer space and shared important insights for further research. From naming a mountain on the Moon, watching and helping from space, and gathering rock samples, here are a few stories that made it to the list:
