America has been a spacefaring nation since 1958. Over the past fifty-three years, America overtook its first rival, the Soviet Union (spacefaring since 1957), and maintained its supremacy in the aerospace and aeronautical industries, having the most developed and successful space program, the strongest private aerospace/aeronautical industry, and the most intelligent engineers and scientists. During times where space exploration and advanced scientific research programs seem inappropriate to publicly fund and continue where economic difficulties, contested military actions, and other civil/financial issues seem to demand precedence, it needs to be promoted that NASA (National Aeronautics and Space Administration) is of immense importance to the security and welfare of the United States of America and must remain a national priority. NASA drives STEM (science, technology, engineering, and mathematics) education as well as the development of commercial and defense technologies and works with private engineering and science companies across the country, employing thousands of brilliant engineers, scientists, and technicians to ensure the safety of the American people and maintain the technological and explorational prestige this country has always possessed.

NASA’s accomplishments are inspirational to students. It is capable of orbiting people around the planet in minutes, building a space station, and placing man on the moon, and in doing so powerfully inspires individuals to aspire for careers with the organization. In order to become involved with NASA, a student must study science, technology, engineering and/or mathematics, and by creating a strong incentive for people to study these topics, demand for STEM education increases. As demand increases, more STEM programs will develop and more people will become involved in STEM disciplines. Students studying STEM subjects develop critical thinking skills and strong senses of logic to overcome various problems and conflicts. New generations of engineers and scientists will rise to replace the retiring generations and surpass them in their accomplishments, but only will do so if opportunities to take such careers exist. Should NASA decay, it won’t only be NASA careers disappearing. Jobs at firms like Lockheed Martin, The Boeing Company, Northrop Grumman, Raytheon, and SpaceX among others will be lost as well and some of these firms will face immense downsizing or possibly even be forced to shut down, severely harming motivation for younger American students to pursue a degree or career in STEM related fields.

One of the greatest positive externalities of NASA is the technology developed as ‘spin-off’ used in the commercial and defense industries. When NASA was tasked with putting man on the moon, NASA realized the Apollo capsule would need computing systems installed within it that were far greater in power and far smaller than those currently in use and therefore tasked private industry with the development of compact computing devices that later became the PC and laptop. Without NASA funding, heart rate monitors, thermal video imaging, light emitting diodes, and velcro among many other technologies would not have been developed. While current domestic debate surrounds whether or not NASA should be downsized, enlarged, or completely phased out over time, foreign countries and blocs such as China, India, and the European Space Agency are investing even more time and money into improving their programs, their educational efforts, and plan to surpass American capabilities within the near future. Technological innovation, though still very prevalent within the United States, is beginning to grow very rapidly in foreign countries and more new technologies are being imported rather than exported every day. Instead of questioning whether or not NASA is necessary, America should be questioning what seemingly impossible task NASA should be working on next. Originally, the Apollo project seemed insurmountably difficult. But when national security threats (Soviet technological capabilities during the Cold War) met technological challenges (the Apollo program), NASA proved to be an irreplaceable source of innovation and wonder that united a nation, inspired a generation with dreams of space exploration, and provided a feeling of security to millions of people who feared another devastating war.

Which is also why NASA is critically important in the defense industry as a customer. NASA helps improve private and public defense and communication technologies. The relationship between NASA and the private industry is very symbiotic. NASA develops a plan or project and administers/contracts production and testing tasks out to the private industry, challenging thousands of engineers and scientists to improve their designs and inspires technological and manufacturing developments, which in turn allow NASA to complete its mission in an efficient and effective manner. China has proven it is capable of destroying our satellites by destroying one of its own and has announced its desire to develop a space program separated from America’s influence and plans to land on the moon in 2020. India, Israel, Iran, Pakistan, Romania, Japan, and Ukraine among others have all had confirmed launches and are working to become space powers themselves, developing their own aerospace industries and programs. Iraq and North Korea have also both touted successful launches, though their success are unconfirmed. NASA helps to keep America competitive by constantly challenging private industry and by making sure its goals for space and technological development are always beyond those of other countries, which helps to prevent enemies from defeating our technologies, thus keeping us safe.

I have just watched this video by Global Futures 2045.

This is my list of things I disagree with:

It starts with scary words about how every crisis comes faster and faster. However this is untrue. Many countries have been running deficits for decades. The financial crisis is no surprise. The reason the US has such high energy costs goes back to government decisions made in the 1970s. And many things that used to be crises no longer happen, like the Black Plague. We have big problems, but we’ve also got many resources we’ve built up over the centuries to help. Much of the challenges we face are political and social, not technical.

We will never fall into a new Dark Ages. The biggest problem is that we aren’t advancing as fast as we could and many are still starving, sick, etc. However, it has always been this way. The 20th century was very brutal! But we are advancing and it is mostly known threats like WMDs which could cause a disaster. In the main, the world is getting safer every day as we better understand it.

It’s been a while since anyone contributed a post on space exploration here on the Lifeboat blogs, so I thought I’d contribute a few thoughts on the subject of potential hazards to interstellar travel in the future — if indeed humanity ever attempts to explore that far in space.

It is only recently that the Voyager probes provided us with some idea of the nature of the boundary of our solar system with what is commonly referred to as the local fluff, The Local Interstellar Cloud, through which we have been travelling for the past 100,000 years or so, and which we will continue to travel through for another 10,000 or 20,000 years yet. The cloud has a temperate of about 6000°C — albeit very tenuous.

We are protected by the effects of the local fluff by the solar wind and the sun’s magnetic field, the front between the two just beyond the termination shock where the solar wind slows to subsonic velocities. Here, in the heliosheath, the solar wind becomes turbulent by its interaction with the interstellar medium, and keeping the interstellar medium at bay from the inners of the solar system, the region currently under study by the Voyager 1 and Voyager 2 space probes. It has been hypothesised that there may be a hydrogen wall further out between the bow shock and the heliopause composed of ISM interacting with the edge of the heliosphere, another obstacle to consider with interstellar travel.

The short end of the stick is that what many consider ‘open space’ to traverse once we get beyond the Kuiper belt may in fact be many more mission-threatening obstacles to traverse to reach beyond our solar system. Opinions welcome. I am not an expert on this.

On a casual read of the appraised work of Duncan R. Lorimer on Binary and Millisecond Pulsars (2005) last week, I noted the reference to the lack of pulsars with P < 1.5 ms. It cites a mere suggestion that this is due to gravitational wave emission from R-mode instabilities, but one has not offered a solid reason for such absence from our Universe. As the surface magnetic field strength of such would be lower (B ∝ (P ˙P )^(1÷2)) than other pulsars, one could equally suggest that the lack of sub millisecond pulsars is due to their weaker magnetic fields allowing CR impacts resulting in stable MBH capture… Therefore if one could interpret that the 10⁸ G field strength adopted by G&M is an approximate cut-off point where MBH are likely to be captured by neutron stars, then one would perhaps have some phenomenological evidence that MBH capture results in the destruction of neutron stars into black holes. One should note that more typical values of observed neutron stars calculate a 10¹² G field, so that is a 10⁴ difference from the borderline-existence cases used in the G&M analysis (and so much less likely to capture). That is not to say that MBH would equate to a certain danger for capture in a planet such as Earth where the density of matter is much lower — and accretion rates much more likely to be lower than radiation rates — an understanding that is backed up by the ‘safety assurance’ in observational evidence of white dwarf longevity. However, it does take us back to question — regardless of the frequently mentioned theorem here on Lifeboat that states Hawking Radiation should be impossible — Hawking Radiation as an unobserved theoretical phenomenon may not be anywhere near as effective as derived in theoretical analysis regardless of this. This oft mentioned concern of ‘what if Hawking is wrong’ of course is endorsed by a detailed G&M analysis which set about proving safety in the scenario that Hawking Radiation was ineffective at evaporating such phenomenon. Though doubts about the neutron star safety assurance immediately makes one question how reliable are the safety assurances of white dwarf longevity – and my belief has been that the white dwarf safety assurance seems highly rational (as derived in a few short pages in the G&M paper and not particularly challenged except for the hypothesis that they may have over-estimated TeV-scale MBH size which could reduce their likelihood of capture). It is quite difficult to imagine a body as dense as a white dwarf not capturing any such hypothetical stable MBH over their lifetime from CR exposure – which validates the G&M position that accretion rates therein must be vastly outweighed by radiation rates, so the even lower accretion rates on a planet such as Earth would be even less of a concern. However, given the gravity of the analysis, those various assumptions on which it is based perhaps deserves greater scrutiny, underscored by a concern made recently that 20% of the mass/energy in current LHC collisions are unaccounted for. Pulsars are often considered one of the most accurate references in the Universe due to their regularity and predictability. How ironic if those pulsars which are absent from the Universe also provided a significant measurement. Binary and Millisecond Pulsars, D.R. Lorimer: http://arxiv.org/pdf/astro-ph/0511258v1.pdf

Russia’s hastily convened international conference in St. Petersburg next month is being billed as a last-ditch effort at superpower cooperation in defense of Earth against dangers from space.

But it cannot be overlooked that this conference comes in response to the highly controversial NATO anti-ballistic missile deployments in Eastern Europe. These seriously destabilizing, nuclear defenses are pretexted as a defense against a non-nuclear Iran. In reality, the western moves of anti-missile systems into Poland and Romania create a de facto nuclear first-strike capability for NATO, and they vacate a series of Anti-Ballistic Missile Treaties with the Russians that go back forty years.

Deeply distrustful of these new US and NATO nuclear first-strike capabilities, the Russians announced they will not attend NATO’s planned deterrence summit in Chicago this month. Instead, they are testing Western intentions with a proposal for cooperative project for near-space mapping, surveillance, and defense against Earth-crossing asteroids and other dangerous space objects.

The Russians have invited NATO members as well as forward-thinking space powers to a conference in June in Petrograd. The agenda: Planetary defense against incursions by objects from space. It would be a way of making cooperative plowshares from the space technologies of hair-trigger nuclear terror (2 minutes warning, or less, in the case of the Eastern European ABMs).

It’s an offer the US and other space powers should accept.

High energy experiments like the LHC at the nuclear research centre CERN are extreme energy consumers (needing the power of a nuclear plant). Their construction is extremely costly (presently 7 Billion Euros) and practical benefits are not in sight. The experiments eventually pose existential risks and these risks have not been properly investigated.

It is not the first time that CERN announces record energies and news around April 1 – apparently hoping that some critique and concerns about the risks could be misinterpreted as an April joke. Additionally CERN regularly starts up the LHC at Easter celebrations and just before week ends, when news offices are empty and people prefer to have peaceful days with their friends and families.

CERN has just announced new records in collision energies at the LHC. And instead of conducting a neutral risk assessment, the nuclear research centre plans costly upgrades of its Big Bang machine. Facing an LHC upgrade in 2013 for up to CHF 1 Billion and the perspective of a Mega-LHC in 2022: How long will it take until risk researchers are finally integrated in a neutral safety assessment?

There are countless evidences for the necessity of an external and multidisciplinary safety assessment of the LHC. According to a pre-study in risk research, CERN fits less than a fifth of the criteria for a modern risk assessment (see the press release below). It is not acceptable that the clueless member states point at the operator CERN itself, while this regards its self-set security measures as sufficient, in spite of critique from risk researchers, continuous debates and the publication of further papers pointing at concrete dangers and even existential risks (black holes, strangelets) eventually arising from the experiments sooner or later. Presently science has to admit that the risk is disputed and basically unknown.

I have on occasion used the term ‘the neutron star paradox’ amongst LHC safety critics to denote the existence of neutron stars, as micro black hole capture should invalidate their existence if micro black holes were stable, according to official safety reports. The oft used counter-argument being that of superfluidity, which I personally dismiss as bunkum (zero viscosity cannot slip and slide your way out from the dark side of an event horizon).

It would be more appropriate to consider the magnetic field of the neutron star such that cosmic rays are always deflected by the Lorentz force from such stars, or perhaps some solar wind type effect may do similar (though this has at least partly been argued against in safety assurance already). The alternative (and infinitely more plausible) explanation of course is that micro black holes (TeV scale, at least) do not exist, though dozens of papers on arXiv and other journals argue otherwise (and CERN scientists willfully anticipate the creation of approx. 10,000 of these over the course of LHC experiemnts). The slightly less plausible explanation is that Hawking Radiation Theory is actually effective, with the only other explanation being that MBH accretion models are flawed. Otherwise we would not have stable neutron stars in the Universe… they would all be black holes by now.

I thought I’d kick off a thread of discussion here — if anyone has the appetite to participate — on discussion of ‘The Neutron Star Paradox’, as you will see from my previous post on the flux of (hypothetical) stable micro black holes, this is quite central to LHC safety assurance.

- CERN’s annual meeting to fix LHC schedules in Chamonix: Increasing energies. No external and multi-disciplinary risk assessment so far. Future plans targeting at costly LHC upgrade in 2013 and Mega-LHC in 2022.

- COMMUNICATION to CERN – For a neutral and multi-disciplinary risk assessment before any LHC upgrade

According to CERN’s Chamonix workshop (Feb. 6–10 2012) and a press release from today: In 2012 the collision energies of the world’s biggest particle collider LHC should be increased from 3.5 to 4 TeV per beam and the luminosity is planned to be increased by a factor of 3. This means much more particle collisions at higher energies.

CERN plans to shut down the LHC in 2013 for about 20 months to do a very costly upgrade (for CHF 1 Billion?) to run the LHC at double the present energies (7 TeV per beam) afterwards.

As we all know, Venus’s atmosphere & temperature makes it too hostile for colonization: 450°C temperatures and an average surface pressure almost 100 times that of Earth. Both problems are due to the size of its atmosphere — massive — and 95% of which is CO₂.

The general consensus is that Venus was more like that of the Earth several billion years ago, with liquid water on the surface, but a runaway greenhouse effect may have been caused by the evaporation of the surface water and subsequent rise of greenhouse gases.

It poses not just a harsh warning of the prospects of global warming on Earth, but also a case study for how to counter such effects — reversing the runaway greenhouse effect.

I have wondered if anyone has given serious thought to chemical processes which could be set in motion on Venus to extract the carbon dioxide from the atmosphere. The most common gas in the Universe is of course hydrogen, and if sufficient quantities could be introduced to the Venusian atmosphere, with the appropriate catalysts, could the carbon dioxide in the atmosphere be eventually reversed back into solid carbon compounds, water vapor and oxygen? The effect of this would of course not only bring down the temperature, but return the surface pressure, with 95% of its atmosphere removed, to one more similar to that of Earth. Perhaps in adding other aerosols the temperatures could be reduced further and avoid a re-runaway effect.

I’d like to hear others thoughts on this. It would be a long term project — but would perhaps make our closest planet our most habitable one in the future — one we could turn into a habitat that would be very accessible, with ample oxygen, water and mineral resources… The study of such a process would also greatly benefit Earth in the event that theorized runaway greenhouse effects start to occur on our own planet, the strategies learned could save it. Other issues to address regarding Venus: lack of magnetic field and its slow rotation would have to be considered, though hardly off-putting, and 150ppm sulfur dioxide in the atmosphere would need to be cleansed — surely not insurmountable.
