Space Tourism

…isn’t for sissies:

Other physical challenges are more difficult to address and also less acute. Humans in space suffer muscle and bone atrophy. Space travel requires exposure to increased levels of radiation, which can lead to surprising visual effects. “All of a sudden you will see this really intense, bright white … and then it will fade back out,” says Garriott de Cayeux. “That is basically you being damaged by radiation, it triggers the impression of light even though there is no light.”

His time in space required a year of difficult preparation, although physical fitness wasn’t a focus. “If you’re going on a space walk, you need to be in excellent physical condition, because an inflated space suit is hard to bend. But if you’re not, you just need to be healthy,” he says. Still, SpaceX’s tourism clients will likely be studied head to toe, undergoing a battery of medical tests they’ve probably never heard of before. “In my case, they found I was missing a vein on one lobe of my liver,” says Garriott de Cayeux. “On Earth that’s irrelevant, but in space it could have led to internal bleeding, which is why I ended up having surgery to remove that lobe.”

Yes, word of mouth will dissuade and reduce the market, but many will still find it worth it. and

The Death Of Expertise

7 Comments

Thoughts from Glenn Reynolds:

In the realm of foreign affairs, which should be of special interest to the people at Foreign Affairs, recent history has been particularly dreadful. Experts failed to foresee the fall of the Soviet Union, failed to deal especially well with that fall when it took place, and then failed to deal with the rise of Islamic terrorism that led to the 9/11 attacks. Post 9/11, experts botched the reconstruction of Iraq, then botched it again with a premature pullout.

On Syria, experts in Barack Obama’s administration produced a policy that led to countless deaths, millions of refugees flooding Europe, a new haven for Islamic terrorists, and the upending of established power relations in the mideast. In Libya, the experts urged a war, waged without the approval of Congress, to topple strongman Moammar Gadhafi, only to see — again — countless deaths, huge numbers of refugees and another haven for Islamist terror.

It was experts who brought us the housing bubble and the subprime crisis. It was experts who botched the Obamacare rollout. And, of course, the experts didn’t see Brexit coming, and seem to have responded mostly with injured pride and assaults on the intelligence of the electorate, rather than with constructive solutions.

By its fruit the tree is known, and the tree of expertise hasn’t been doing well lately. As Nassim Taleb recently observed: “With psychology papers replicating less than 40%, dietary advice reversing after 30 years of fatphobia, macroeconomic analysis working worse than astrology, the appointment of Bernanke who was less than clueless of the risks, and pharmaceutical trials replicating at best only 1/3 of the time, people are perfectly entitled to rely on their own ancestral instinct and listen to their grandmothers.”

There was also the failure of the CIA to see the Iranian revolution coming. And certainly the “experts” in charge of space policy haven’t been covering themselves in glory, at least if the goal is to expand humanity’s economic sphere into the solar system (as Marburger once said).

Stem Cells

2 Comments

…in spaaaaaaaace:

“Stem cells are inherently designed to remain at a constant number,” Zubair explains. “We need to grow them faster, but without changing their characteristics.”

The first phase of the investigation, he adds, is answering the question: “Do stem cells grow faster in space and can we grow them in such a manner that they are safe to use in patients?”

Investigators will examine the space-grown cells in an effort to understand the mechanism behind microgravity’s effects on them. The long-term goal is to learn how to mimic those effects and develop a safe and reliable way to produce stem cells in the quantities needed.

Just once, it would be nice to discover something that can be done in space that can’t be later mimiced on the ground. I hope that Made In Space has found one.

And of course, as I point out in the book, this kind of research could be accelerated if they added one more crewperson to ISS. The only reason they haven’t is lifeboat requirement, something that doesn’t exist in Antarctica.

Confession Of A “Climate-Change Denier”

Yes:

There are two things necessary for a mass movement to succeed: true believers and a well-defined enemy. The enemy of the climate change mass movement is fossil fuels and the Industrial Age, with the “deniers” being the enablers of planetary destruction.

In the past, the term “denier” has been associated with that extreme group who denies the existence of the horrible, tragic historical fact, the Holocaust. Many climate change true believers want the public to put anyone who questions or disagrees with climate change projections in the same category as the Holocaust deniers. But one is a fact, the other a contested projection. Nevertheless, they have been quite successful.

Here is one of the definitions of “denier” found on the Internet: “a person who denies something, especially someone who refuses to admit the truth of a concept or proposition that is supported by the majority of the scientific or historical evidence: a prominent denier of global warming.”

Here is Hoffer’s warning on the role of the true believer: “where mass movements can either persuade or coerce, it usually chooses the latter.”

Something we are seeing in spades.

It’s demagoguery. And it trivializes the Holocaust itself, in the service of a(nother) collectivist political agenda.

A New Cholesterol Drug

I’m suspicious of these results. And like most such studies, they’re not properly controlled, and we don’t know if we’re treating a symptom. It may be that the drug does reduce risk, but that the LDL reduction is a side effect, not the reason that the risk is reduced. And notice that there is no mention whatsoever of diet. My LDL is very low since I cut back on carbs.

You have lost control of the oil market, probably permanently. Boo hoo.

[Monday-morning update]

OPEC’s cuts are treading water. “The simplified version is that U.S. oil production is reaching a point where OPEC can choose to sell 100 barrels at $50, or 125 barrels at $40. They can choose between higher profit margins or larger market share, but the days of having both are over for now.”

Trump’s NASA Proposal

Loren Grush has the details.

This is just a proposal; as she notes, Culberson is likely to restore the Europa lander. And in general, the White House proposes, and Congress disposes. What really matters is what gets appropriated.
