Gravity, as the old joke goes, sucks.
It drags us down, pulls on our weary limbs, makes our feet tired, makes parts of us droop. But it’s also a critical factor for our long term well-being. Astronauts and cosmonauts circling the Earth over the past 60 years have discovered that zero-g, or microgravity, is really not very good for you. Read more

I remember back to a classic episode of the Guide to Space, where I provided an extremely fascinating and concise explanation for what a quasar is. Don’t recall that episode? Well, it was super. Just super. Alright slackers, let’s recap.
Quasars are the brightest objects in the Universe, visible across billions of light years. Likely blanching life from everything in the path of the radiation beam from its lighthouse of death. They occur when a supermassive black hole is actively feeding on material, pouring out a mountain of radiation. Black holes, of course, are regions of space with such intense gravity where nothing, not even light itself, can escape. Read more

Bitcoin becomes more valuable as bitcoin transactions become more secure. That is an important thing to keep in mind when trying to understand why the hell bitcoin is being launched into space.
Why? Because what’s a more secure place for the computers processing bitcoin transactions than in orbit several miles above the earth? That’s why core bitcoin developer and founder of Dunvegan Space Systems Jeff Garzik has developed the BitSat program, which plans to launch computers on small, (relatively) cheap satellites in 2016.Read more
A realistic and desirable human destination would produce a different space program than what we have today.
“We reach for new heights and reveal the unknown for the benefit of humankind.” This is NASA’s Vision Statement. This is NASA’s reason for being, its purpose. This is a vision statement for science and knowledge. This vision statement was crafted in a solar system that has only one planet that is environmentally friendly to human life.
Thanks to the ongoing search for exoplanets, we’ve identified several planets in our galaxy that are Earth sized and in their star’s habitable zone. Based on statistics, potentially billions more are waiting to be found. We are just now developing the technology to detect them. But we’re nowhere near having the technology needed to get to visit them. They are simply too far away.
Now here is where I’d like to pose a what if question: What if there was another habitable planet just like Earth, right here in our own solar system? What would Earth’s space programs look like, if anyone with a good telescope could look up and see another world with oceans, and continents, and clouds, and green forests? I think that it is safe to say that space programs in this imaginary solar system would be vastly different than ours today. This is conjecture, but it seems likely that the vision statement above, would be more in line with making that new world available for humanity.
Chris Impey, an astronomer at the University of Arizona in Tucson, thinks that the desire to explore, which has pushed humans to cross oceans and conquer mountains, will continue to propel humans into space.
“I think what is happening now is as profound as the transition that took place among hunter gatherers when they left Africa 50 or 60 thousand years ago,” said Impey. “It took an amazing short time – just a couple hundred generations – for simple tribal units of 50 or 100 to spread essentially across the Earth.“Read more
One of the things that I’ve always liked about Star Trek, is the concept of a galaxy spanning civilization. I would expect that before we ever get to that point, we will have a civilization that spans our solar system. Having a solar system spanning civilization has many advantages. It would give us access to resources many times greater than what is found here on Earth. It also provides the opportunity for civilization to expand, and in a worst case scenario, help ensure the survival of humanity.
Millions of people living in spacious environmentally controlled cities on planetary surfaces and in rotating cylinders in free space, with industry that extends from Mercury to the comets is to me, a grand vision worthy of an ambitious civilization. But trying to make that vision a reality will be difficult. The International Space Station has the capacity to house just six people and cost approximately $100B to put in place. With a little simple division, that works out to about $17B per inhabitant! If we used that admittedly crude figure, it would cost $17 trillion to build a 1,000 person habitat in Earth orbit. Clearly, the approach we used to build the ISS will not work for building a solar system civilization!
The ISS model relies on building everything on Earth, and launching it into space. A different model championed by Dr. Philip Metzger, would develop industrial capacity in space, using resources close to home, such as from the Moon. This has the potential to greatly reduce the cost of building and maintaining systems in space. But how to develop that industrial capacity? Remember we can’t afford to launch and house thousands of workers from Earth. The answer it would seem, is with advanced robotics and advanced manufacturing.
But is even this possible? The good news is that advanced robotics and advanced manufacturing are already being rapidly developed here on Earth. The driver for this development is economics, not space. These new tools will still have to be modified to work in the harsh environment of space, and with resources that are different from what are commonly used here on Earth. While learning to adapt those technologies to the Moon and elsewhere in the solar system is not trivial, it is certainly better that having to develop them from scratch!
International Audacious SpaceInitiative Partners with Brussels-Based ISC Intelligence to Support EU’s Horizon 2020 Research and Innovation Goals to Meet Global Challenges on Earth
BRUSSELS/HOUSTON, March 5, 2015 – 100 Year Starship™ (100YSS™), an independent, long-term global initiative working to ensure that the capabilities for human interstellar travel, beyond our solar system to another star, exist within the next 100 years today announced the establishment of its hub in the European Union. The inaugural 100YSS@EUä Hub debuted at the ES:GC2 (European Science: Global Challenges Global Collaboration) Conference held by the Brussels partner ISC Intelligence.
The 100YSS@EU Hub will further the 100YSS mission and facilitate robust transatlantic and international collaboration in research and innovation, science, technology, engineering, and mathematics (STEM) capacity building, entrepreneurship and education projects between organizations, companies, universities and individuals, as well as support the objectives of the EU’s Horizon 2020. The U.S.-based 100YSS began with a competitive seed-funding grant from DARPA (Defense Advanced Research Projects Agency).
Horizon 2020 is the largest EU Research and Innovation programme ever and is aimed at implementing the Innovation Union, a Europe 2020 flagship initiative designed to secure Europe’s global competitiveness.

As a kid, I devoured Star Trek: The Next Generation, and though it now appears nearly as campy as the original series did back then, I still love it. But Star Trek led me astray. I thought exploration for the sake of exploration would get us to the stars. Now, I’m not so sure. Fifty years in, and we humans are still stuck in low-Earth orbit.
First comes a smattering of fiery idealists blazing trails and climbing peaks. The risks are high and the returns are individual fame, newly detailed maps, and a general sense of awe.
The following is short notice, but we just found out this event is open to the public.
You’re invited!
To an announcement of the formation of a new coalition of organizations focused on space development — with special guests Rep. Dana Rohrabacher and Rep. Chaka Fattah.
