How easy will it be to build a Moon base?

Posted by in categories: materials, space

Musk has yet to make a definite announcement about a Moon base. He has said we may need one just to get people fired up about Mars, and he is going to shoot someone around the Moon and back. I point this out because the first part of this article makes it seem like Musk has drawn up plans and announced them.


How can astronauts build a lunar base if traditional building materials are too heavy to load into a rocket?

What Happened to the 100,000-Hour LED Bulbs?

Posted by in categories: life extension, space

An excellent article on Hackaday addresses the lifetime of LED bulbs. To a certain degree, it also addresses the lifetime of LED’s themselves. However, the majority of the article investigates the various parts of the LED bulb, such as electronics and housings, and how they last. The article also addresses the issues of lumen depreciation and color change.

These issues are all important when thinking about long-term use in space applications.


Early adopters of LED lighting will remember 50,000 hour or even 100,000 hour lifetime ratings printed on the box. But during a recent trip to the hardware store the longest advertised lifetime I found was 25,000 hours. Others claimed only 7,500 or 15,000 hours. And yes, these are brand-name bulbs from Cree and GE.

Scientists reveal true shape of Milky Way: It’s warped & twisted

Posted by in categories: energy, mapping, space

It’s even more fascinating than we thought.


The Milky Way looks nothing like the flat space pancake it is usually depicted as. The newly-created and most accurate 3D map of our galaxy reveals that it’s warped and twisted, and even more fascinating.

A group of astronomers from Australia and China have built their “intuitive and accurate three-dimensional picture” by mapping the so-called “classical Cepheids.”

These Four Universities Are Trying to Figure Out Space Law

Posted by in categories: geopolitics, law, military, space, treaties

Jack Beard, a professor in the University of Nebraska College of Law’s Space, Cyber and Telecommunications Law Program, told Politico that the Woomera Manual on the International Law of Military Space Operations “will become the definitive document on military and security law as it applies to space.”

The Woomera Manual won’t actually lay out any new guidelines. Instead it will organize and present the laws that are already on the books so that politicians, industry leaders, and others can make better informed decisions regarding activity in space.

Given the fact that the Outer Space Treaty, which banned military actions in outer space, has all but been tossed aside, it’s unclear how much they’ll actually listen.

This Wild Moon Base Idea Came from Architecture Students (Video)

Posted by in categories: engineering, habitats, space, sustainability

Interesting concept.


Architectural students working with the European Space Agency (ESA) have created a new concept for a sustainable lunar habitat.

The ESA’s astronaut center in Cologne, Germany, partners with universities and research institutions to study moon-related concepts in preparation for future missions. Angelus Chrysovalantis Alfatzis is one of the researchers who has contributed to the development of a promising concept for a moon base, according to a statement from ESA.
