The Future of the Space Program

Monday, July 11th, 2011

National Space Society CEO Mark Hopkins issues the following statment based on his speech at the 2011 International Space Development Conference (see 7-minute video of speech). For media interviews contact Mark.Hopkins@nss.org.


The ultimate goal of the National Space Society is nothing less than the settlement of space and the use of its vast resources for the dramatic betterment of humanity.

According to the Augustine Report, which set the stage for the human space program proposed by President Obama, a Democrat: …the ultimate goal of human exploration is to chart a path for human expansion into the solar system.

According to Dr. John Marburger, science advisor to the just previous president, George Bush, a Republican: President Bush’s space vision…is to begin now for a future in which the material trapped in the sun’s vicinity is available for incorporation into our way of life.

Democrats, Republicans, and the National Space Society all agree in a general sense as to what the future of humanity in space should be.

The National Space Society’s near-term strategy is to support those aspects of the space program that most accelerate humanity’s drive towards this goal.

It has been said many times that the Earth’s resources are limited and this is true. It is also true that the average human is very poor by American standards. The poverty line in the United States is a factor of three below our per capita income. The average human lives at a standard of living well below our poverty line. The per capita income of the average human is a factor of seven below that of the average American.

In the long run, the average human standard of living should be increased to at least what it is in the United States today. Even if we assume that human population does not increase and that the American standard of living does not increase, then to accomplish this goal, the human economy must increase by a factor of seven. To a first approximation, this means that resource consumption must also be increased by a factor of seven. When we take into account the fact that in actuality the population will continue to increase and that we want the standard of living of America and other developed countries to increase and rightfully so, then this factor of seven becomes much larger. Where will we obtain the needed resources and do so in an environmentally benign fashion?

The media has bombarded the American public with the idea that resources are limited, that we are beginning to reach resource constraints, and that the environment is deteriorating.

According to polls taken just before the current recession, the average American believes, for the first time in history, that future generations will be worse off than they are. Europeans are even more pessimistic.

A fundamental part of the American dream is that each generation will be better off than the one before. Americans no longer believe this to be true. There is a profound hunger in the land for a vision of the future, which allows the American dream to be restored.

Fortunately, the vast majority of the resources of the solar system in terms of both energy and materials lie in space rather than on the Earth. This is true by many orders of magnitude.

For example, the Sun produces 10 trillion, that is TRILLION with a T, times the amount of energy currently consumed by humans.

In the long run — and I will not speculate tonight on how long it will be — the Earth’s resource constraints can be overcome by the resources of space.

There are some who argue that Americans should seek to meekly accommodate themselves with the resource constraints of Earth. This is not the American way. Americans deal with constraints by SMASHING them. In the long run, space allows us to do this.

What does all of this mean?

Space is not just about obtaining new technology, although that is important.

Space is not just about applications, such as communication satellites, although that is important.

Space is not just about new knowledge, although that is important.

Space is not just about exploration, although that is important.

Space is not just about defense, although that is important.

Space is not just about all of these benefits combined plus the other benefits commonly cited by the space community.

Space is far more important. Space is nothing less than the foundation of the human future. American society as a whole has not fully grasped this fact, because we in the space community are overly modest.

Space is not a luxury. Space is not nice to have. Space is of fundamental importance to human destiny.

Space and its resources can provide a prosperous future, a future which restores the American dream, a hopeful future for all.

British Research Team Will Test Laser for Space Based Solar Power

Saturday, July 9th, 2011

Using small solar satellites that beam power to Earth has recently become a popular idea. Various groups have shown an interest, including the military for remote expeditions and governments that can use it for disaster relief and even remote desalination plants.

Stephen Sweeney and his colleagues from the University of Surrey, in England, will test a fiber laser in Germany. Using a wavelength of 1.5 microns, it will be within the infra-red part of the spectrum. The goal of the project is to test the effects of atmospheric pollutants and water vapor on the beam. Read the full story from The Economist.

If the test goes well, Europe’s largest space company, EADS Astrium, is interested in flying a space-based demonstration within five years. Read the full story from BBC News.

Statement by the President on the Launch of the Space Shuttle Atlantis

July 8, 2011

Today, Americans across the country watched with pride as four of our fellow citizens blasted off from the Kennedy Space Center in the Space Shuttle Atlantis, and America reached for the heavens once more.

Behind Atlantis and her crew of brave astronauts stand thousands of dedicated workers who have poured their hearts and souls into America’s Space Shuttle program over the past three decades. To them and all of NASA’s incredible workforce, I want to express my sincere gratitude. You helped our country lead the space age, and you continue to inspire us each day.

Today’s launch may mark the final flight of the Space Shuttle, but it propels us into the next era of our never-ending adventure to push the very frontiers of exploration and discovery in space. We’ll drive new advances in science and technology. We’ll enhance knowledge, education, innovation, and economic growth. And I have tasked the men and women of NASA with an ambitious new mission: to break new boundaries in space exploration, ultimately sending Americans to Mars. I know they are up to the challenge – and I plan to be around to see it [emphasis added].

Congratulations to Atlantis, her astronauts, and the people of America’s space program on a picture-perfect launch, and good luck on the rest of your mission to the International Space Station, and for a safe return home. I know the American people share my pride at what we have accomplished as a nation, and my excitement about the next chapter of our preeminence in space.

Beam it up, Scotty: 3D Printing may have space applications

Friday, July 8th, 2011

Tools and mechanical parts might be “beamed” up to a space station or a lunar or Mars base using technology that has in recent years become a central process in design prototyping known as 3D printing or SLS (selective laser sintering). In this technology, an object is scanned and a powdery substance is converted via a heating process into a duplicate solid form. A striking demonstration of this technology can be seen in this 4-minute video clip from the National Geographic Channel.

A variation of the technology might also be used for lunar materials production by fabricating items from lunar regolith. Markus Kayser has demonstrated a prototype “Solar Sinter” device that uses the power of the sun to produce glass-like objects made from desert sand. You can view a 6-minute video demonstration of the device as tested in the Sahara Desert.

Obama on Space at Twitter Town Hall

Wednesday, July 6th, 2011

July 6, 2010: President Obama answers a question about space at his Twitter Town Hall.

QUESTION: “Now that the space shuttle is gone, where does America stand in space exploration?”

THE PRESIDENT: We are still a leader in space exploration. But, frankly, I have been pushing NASA to revamp its vision. The shuttle did some extraordinary work in low-orbit experiments, the International Space Station, moving cargo. It was an extraordinary accomplishment and we’re very proud of the work that it did. But now what we need is that next technological breakthrough.

We’re still using the same models for space travel that we used with the Apollo program 30, 40 years ago. And so what we’ve said is, rather than keep on doing the same thing, let’s invest in basic research around new technologies that can get us places faster, allow human space flight to last longer.

And what you’re seeing now is NASA I think redefining its mission. And we’ve set a goal to let’s ultimately get to Mars. A good pit stop is an asteroid. I haven’t actually — we haven’t identified the actual asteroid yet, in case people are wondering. (Laughter.) But the point is, let’s start stretching the boundaries so we’re not doing the same thing over and over again, but rather let’s start thinking about what’s the next horizon, what’s the next frontier out there.

But in order to do that, we’re actually going to need some technological breakthroughs that we don’t have yet. And what we can do is for some of this low-orbit stuff, some of the more routine space travel — obviously no space travel is routine, but it could become more routine over time — let’s allow the private sector to get in so that they can, for example, send these low-Earth orbit vehicles into space and we may be able to achieve a point in time where those of you who are just dying to go into space, you can buy a ticket, and a private carrier can potentially take you up there, while the government focuses on the big breakthroughs that require much larger investments and involve much greater risk.

Australians Receive Funding for Plasma Thruster

Tuesday, July 5th, 2011

Australia National University’s Plasma Research Laboratory has received a grant to help build its Helicon Double Layer Thruster (HDLT). If successful, the driver could be in space as early as 2013.

Because of the high temperatures generated in plasma drives, the trick is confining the hot gas without it destroying the chamber. For this, the HDLT uses a magnetic field in the source tube, where a gas like Krypton or Xenon is heated by a radio antenna. In space, the researchers hope that less than one gram of propellant would power a five-hour burn.

The End of the Space Age?

Monday, July 4th, 2011

The cover story of the July 2 edition of The Economist loudly proclaims “The End of the Space Age.”

National Space Society Director Al Globus responds below (opinions expressed are his own and not necessarily those of the National Space Society).


The last space shuttle flight is on the launch pad, so we can expect any number of gloom and doom articles like The Economist’s  “The end of the Space Age.” These articles mourn the end of the socialist model of human space flight: government developed, owned, and operated vehicles taking government employees into space.  “The end of the Space Age” is particularly odd because it starts with a long list of vigorous commercial space activities, which together have a combined budget perhaps 10 times greater than NASA’s.  In other words, “No bucks, no Buck Rogers” doesn’t mean the bucks have to come from government.  In fact, there are a lot more bucks if they don’t.

The piece goes on to claim that we will henceforth be limited to Low Earth Orbit (LEO).  Apparently The Economist didn’t notice that the Russians have already sold one seat for a private mission around the Moon and, if they can sell one more, the mission is a go. Furthermore, as these articles frequently do, The Economist ignores the rover on Mars, the orbiters circling Mars, Moon and Mercury, the mission to Pluto, and the private robotic race to the Moon spawned by the Google Lunar X Prize. It’s as if Lewis and Clarke’s primary objective, creating detailed maps, is somehow irrelevant if done comprehensively and accurately by robots at relatively low cost.

What is really happening is that space development is moving beyond national prestige projects towards delivering direct value to people on the ground.  NASA, and The Economist, have not yet realized this. Most of NASA’s budget, the human space flight program and space science, has almost no direct benefit to the people who pay for it. The parts that do directly benefit taxpayers, Earth observation, solar science, protection from asteroids, and aeronautics, are woefully underfunded by comparison. Worse, space solar power receives no funding at all, even though successful development would solve major energy and environmental problems, not to mention put those who do it in the global energy driver’s seat. After all, what would make a nation stronger, a man on Mars for a few months or a terawatt of space solar power? What would protect us better, knowledge of quasars or knowing exactly which asteroids are likely to hit us and how to deflect them? The cost to government of developing space solar power and finding asteroids is a fraction of heavily funded but significantly less useful activities.

The Economist bemoans the fact that the International Space Station (ISS) is due to be deorbited in 2020.  They fail to mention that until a year or two ago it was scheduled to be deorbtied in 2014, and that by 2020 there may well be a private alternative. Bigelow Aerospace has two small space stations in orbit and is developing a full sized facility as you read this. The market: national human space flight programs for a tiny, tiny fraction of the $100 billion cost of the ISS. However, to succeed, Bigelow Aerospace needs a commercial launch vehicle for the crews. Fortunately, President Obama has proposed and funded a program to do exactly that:  develop private commercial human space launch.

I mourn the end of the shuttle. The shuttle is, by far, the most capable space vehicle ever built. However, the coming government fiscal tsunami will severely reduce all government programs, including NASA. We need to refocus NASA’s brilliant space program on developing industry and commerce. Our model should be space communications, which pays lots of taxes today, not the Apollo program, which has been dead for 40 years. Ask yourself, what will make us stronger and more space-capable: putting small numbers of government employees on big rocks far away? Or developing space solar power, space tourism, micro-g materials, and asteroid mining?

SpaceWorks Commercial Releases Analysis of Its First Revenue Space Solar Power Satellite Concept

Monday, July 4th, 2011

The latest addition to the NSS Space Solar Power Library is a new paper released by SpaceWorks Commercial entitled “Operational Demonstration of Space Solar Power (SSP): Economic Analysis of a First Revenue Satellite (FRS)” [PDF], presented at the recent 28th International Symposium on Space Technology and Science (ISTS) in Japan.

The FRS would be a mid-power (1-20 MW of delivered power) space-to-ground demonstrator of SSP. The purpose would be two-fold: prove the end-to-end technical capability and then demonstrate operations over multiple years. The system would be turned over to commercial operators for public/private service.

A Fusion Thruster for Space Travel

Saturday, July 2nd, 2011

IEEE Spectrum reports that a NASA engineer has come up with a new way to fling satellites through space on mere grams of fuel, tens of times as efficiently as today’s best space probe thrusters. Instead of using deuterium and tritium as the fuel stocks, the new motor extracts energy from boron fuel. Using boron, an “aneutronic” fuel, yields several advantages over conventional nuclear fusion. The idea is a long way from becoming a practical device, however.
