New Thunder

New Thunder

I am pleased to announce that I have just published an exciting new e-book called New Thunder. This science fiction story is set in the distant future among the descendents of Earth who have been scattered across seven remote planets light years from the home world. The main character, Avalon Parder is a cocky military star-pilot, humbled to a desk job of lowly military attache by his outrageous behavior.

Unknown to Captain Parder a profound action adventure awaits him which unfolds as a enigmatic mystery spread across the seven alien worlds founded by Earth. It is a classic struggle of stubborn will of one man versus the ruthless control of a federated government just on the verge of perfecting a total mind control super weapon. Parder is a resourceful & clever fighter, but so are his adversaries. His one advantage is a gift from the distant masters of Earth who have left humanity an incredibly capable space craft, the Omega Equinox, with her one man crew sworn to assist Avalon in his quest no matter the outcome.

I hope you will enjoy this unique action story which can found as an e-book at amazon.com at: http://www.amazon.com/dp/B0080ID5ZQ

Why do robots have all the fun? May 2, 2012

The robot explorer Opportunity passes a milestone of its ninth year on Mars this month. What a testimony to a first rate engineering team and what can be done if we want to do something difficult. Is it just me or am I the only one who gets irritated that little “rovers” are exploring Mars. Don’t get me wrong, it is nice to know what is on the surface of Mars but when I see incredible vistas and fascinating objects littering the landscape of Mars I get a little jealous.  I want to be the one drilling a rock, climbing the rim of a crater or motoring along the red sands. Well maybe not me, but a human, not a machine. The old videos of the Apollo guys doing, well, human stuff on the Moon, like wringing out the moon buggy or drilling core samples or whatever. Now I can identify with a person doing things that you or I would do, but a little R2 unit clicking and chirping along; that is less that thrilling.

The next “explorer” NASA has in route to Mars is named Curiosity and is set to touch down in August of this year. It is a SUV sized rover that will do what else; sniff out water and microbial life. I think it is time to find out for ourselves if Mars can support life. We should be sending SUV sized remote construction vehicles preparing the infrastructure for a human habitat. Now that is a goal that people could get excited about. We’ll bring our own SUV’s and do some roving for ourselves. Feature an astronaut cruising across a brilliant red dessert landscape with their arm out the window of their space rated Hummer making some dusty tracks to the next ridge to see what is over it when “crunch”. “Oops, sorry little fellow didn’t see you there digging for Mars cooties.”  Microbes, that’s what you use to make beer, not blowing a billion or two in order to find them on Mars for what possible reason?  Humans need to have a little fun too since we foot the bill.

Next time you see a photo of the Mars surface envision yourself at the wheel of your own rover laying down a red dust trail with a huge grin on your face. Now that’s exploring!

The Book: Mining the Sky
by John S. Lewis

The recent announcement by Planetary Resources about forming a venture to mine asteroids is no new concept. In 1996 John Lewis published the book Mining the Sky.

Dr. Lewis is a professor of Planetary Sciences at the University of Arizona in Tucson. In his book he details how humanity might one day tap the huge resources in our solar system. Each chapter is introduced by a vignette of a some future scenario where we are already actively engaged in space mining and colonization.

This book is a must read for anyone who wants to know where Planetary Resources is headed since Professor Lewis is a key technical advisory. Based on the depth of his understanding of the physics & logistics of space mining as well as the potential of our solar system it seems they are in good hands.

Mining the Sky is a fascinating look at a possible future for any culture with the will to go into space with a real mission beyond finding extraterrestrial microbes.

Asteroid mining has arrived! April 24, 2012

This is the most exciting space news in decades! Start-up firm Planetary Resources announce today that is was establishing a business to mine asteroids in space. They are backed by a powerful collection of thinkers and billionaires to pull it off including Larry Page (Google founder), Dr. Eric Schmidt,  Ross Perot Jr. , Dr.Charles Simonyi and James Cameron are among those participating in the venture.

Their first effort will be to orbit a telescope capable of  detecting candidate  asteroids which are close to Earth  for mining.  Once identified they ” …plan to mine Near-Earth Asteroids (NEAs) for raw materials, ranging from water to precious metals.”  What a milestone this is in placing the future of space exploration and utilization into the hands of practical people, not NASA scientists bent on finding microbial life under some rock.

A great deal of work is yet to be done but this is clearly some of the best news imaginable regarding the opening up space beyond government contrived waste & folly.

Is finding microbes really exploring space? April 23, 2012

I saw an article on Space Daily that shows the absurdity of letting “scientists” set the agenda for exploring space. The article Bringing Mars Back to Earth which discusses how an international group of space snobs (including NASA technocrats)  thinks we should waste time returning to Earth rock samples from Mars hoping for signs of ancient microscopic life. This is moronic and engenders absolutely no interest among tax paying citizens asked to fund such a folly. This group says it will take three mission to Mars to return samples. What a colossal waste of time and resources. Why are such credentialed  mis-guided people allowed to set the ageda for space exploration? Because our leadership is clueless and has no vision or agenda what so ever.

We need to rebel against such nonsense and demand from NASA (No Advancement Since Apollo) and government an agenda for HUMAN exploration of near space. Why not a create a project; ditch NASA and it bureaucracy and take the money to establish a permanent human occupied outpost on Mars!  Such and initiative would inspire people and lead to a human presence outside of Earth which is legitimate human exploration, not twiddling test tubes looking for microscopic “evidence”.

I urge you to email the  Committee on Science & Technology, which is the US government agency responsible for NASA & let then know the we want to see red Martian dust on an American astronauts boots, not Mars rocks. We have enough rocks in the heads of NASA administrators & “scientists” to examine for decades.

Nuclear rockets anyone? April 19, 2012

I have been doing a lot of research on propulsion for spacecraft lately and I came across a paper titled Nuclear Space Power and Propulsion  by the International Academy of Astronautics (IAA). At 224 pages, which contain a lot of math that will make your skull shrink, it is comprehensive.  It is not a casual look at the technology, rather it is a serious attempt to quantify the design challenges, risks and development necessary if this technology is to be used in space. You come away wondering if there isn’t a better way, but the paper makes some excellent observations about the trade offs of going nuclear.

It is hard to imagine in the aftermath of the Fukushima mess that the general public would stand for anything nuclear and large launching into space. Still the distances between planets is such that conventional chemical rockets are cumbersome for extended trips, not to mention the huge side affects of long periods of zero g, which nuclear propulsion promises to reduce. It seems if there was a way around terrestrial sourcing of the fuel were possible a lot of the concerns would be diminished. Asteroid mining anyone?

Water, water everywhere… April 17, 2012

The recent mission to the moon like the LRO & LCROSS have determined that water likely exists in Lunar polar regions. This is great news for missions to the moon and beyond. Water is essential for exploration of  more distant locations for a couple of very important reasons like; we drink it and we can make rocket fuel out of it. The lunar surface is intriguing since it is much easier to loft a payload from a body with gravity that is only 16% that of earth.

What makes real sense is the concept of an autonomous plant which can locate and process the water ahead of us and store it until we get there. Such a concept demonstrator is being considered at NASA. This is the kind of break away thinking that will allow a mission to Mars or elsewhere there is water. It would reduce enormously the amount of mass,  supplies & propellant, we would need to take with us. This “live off the land” philosophy could be expanded to other areas too like remote materials processing and fabrication. If we use local resources we will have a lot less to lug along making such an endeavor as a manned Mars mission possible and a whole lot less complex. Can’t wait to sample the first tall glass of ice cold Martian water.

Space based solar power April 16, 2012

Over time there have been initiatives to move the production of solar energy into space. The thought is that the relative power available is higher than on earth without the  atmosphere attenuating it and also the facility is never on the night side of the planet. Transferring the energy from space to earth would be via wireless power transmission (WPT) which could be done via micro wave transfer to a terrestrial receiver. This concept is not new, it was patented by Dr. Peter Glaser back in 1973. Tests were run by NASA  in the ’70s at their Goldstone facility which were promising and indicated transmission efficiency of 80%.

Now there is new interest since the International Academy of Astronautics (IAA) published a paper on space power in August of last year. This comprehensive study called Space Solar Power delineates the technology, economics and logistics of generating power in space for terrestrial consumption.

What a great reason to live and work in space;  assembling large collector arrays to beam energy to our planet. Sign me up!

Solar Sails – Take me with you! April 12, 2012

Solar sail unfurledI like free and traveling through space with no fuel is a good kind of free. NASA has plans to orbit a large demonstration solar sail in 2014. By large I mean 124 feet square or 15,376 sq. ft.! It will be the largest solar sail flown to date. Using just solar radiation pressure from the sun it will create a very small amount of thrust but it is constant thrust. This is perfect for certain missions like ferrying supplies or propellant from one point in space to another point in space at no cost for fuel; all of this at 70 lbs. of mass. The sail uses steering vanes for attitude control, again propellant-less maneuvering.

The L’Garde Technology Demonstration Mission will demonstrate maneuverability, trim and stability as well as precision navigation to a specific location in space. It is to  be launched with a Falcon 9 rocket by Space X, the premier commercial start-up rocket company.

Now if they just had Windjammer Barefoot Cruises to Mars…

Zero “g” is fun – for a while. April 11, 2012

Watching the astronauts float around the ISS is intriguing. It looks like fun, and everyone who has been in space says it is. The only problem is the long term affects micro gravity has on the human body. Now imagine floating around for six months on your way to Mars. That’s where fun ends and pain begins. Once on the surface you are back in a gravity environment which takes time to re-adapt. This is precious time you could be exploring at 100% capacity, not slugging along dragging your butt to the next task. Months of zero g leads to a host of issues like loss of calcium in the bones and other maladies, some which are reversible, others are not. This is in spite of rigorousness exercise on state of the art space workout equipment on board the station.

NASA is looking at a very old artificial gravity concept. This idea dates back to at least the 1950’s.  The current project is called Nautilus-X or AG ISS, a rotating torus that will be attached to the ISS to test the concept of rotating the cabin to produce a partial gravity environment for sleep & work. It makes a lot of sense and is one possible answer to improved health on long duration space flights. They are also considering a spacecraft based on this same concept.

Now they are finally coming around to the rotating space stations like the marvelous one in the movie 2001 a Space Odyssey. (Well sort of) Aesthetically the ISS is a kludge by any standard. It looks like a train wreck with gym equipment stuck to it and inside; humans bouncing off the walls in a micro-gravity environment. Let’s hope the torus idea catches on and we give our astronauts a healthier and safer way to explore the solar system.
