To save money, NASA management has shut down a troubled program to build a more efficient plutonium power supply for its deep space missions.

The cancelled ASRGs would have generated electrical power from the expansion of gas warmed by the radioactive decay of plutonium-238. NASA says that the devices have the same power output as its current generation of Multi-Mission Radioactive Thermoelectric Generators (MMRTG) but use four times less plutonium-238, a scarce resource. One MMRTG with 4.8 kilograms of plutonium is currently powering the Curiosity rover on Mars.

The United States has less than 40 kilograms of plutonium-238 left, but the DOE restarted production this year. Green says he is confident that the DOE will be producing plutonium-238 at a rate of 1.5 kilograms per year by 2019. He says that the stockpiled plutonium-238, along with the new supply, will be enough to send another planned rover to Mars in 2020 and to complete other missions in the 2020s – without any need for the extra efficiency of the ASRGs.

The ASRG program had been a year and a half behind schedule and had had its management team replaced at one point.

A close look at another government program to try to lower the cost to orbit.

A close look at another government program to try to lower the cost to orbit.

The latest program is know as the Experimental Spaceplane — or XS-1. The objective “is to demonstrate a reusable first stage launch vehicle capable of carrying and deploying an upper stage that inserts 3,000 to 5,000 lb. payloads into Low Earth Orbit (LEO), designed for less than $5M per launch for an operational system.” The system has to be able to perform with aircraft-like operations. And demonstrate the ability to fly 10 times in 10 days. It needs to reach Mach 10 at least once. And provide the basis for next-generation launch services and “global reach hypersonic and space access aircraft.”

Forgive me if I am skeptical. Despite DARPA’s reasonable success (It helped make possible SpaceX’s Merlin engine), these government efforts generally fail because they are unattached to the prime reasons for lowering cost: competition and profits. Consider this very accurate historical summary in the article above:

In the era of bell bottoms and Richard Nixon, there was the space shuttle. When Ronald Reagan ruled the roost, all hope rested in the National Aerospace Plane. During the Bill Clinton era, there were the X-33 and Venture Star. In Barack Obama’s first term, the Air Force pursued its Reusable Booster System (RBS).

Five programs. One objective: to radically reduce the cost to orbit. More than $14 billion spent on development. And the result? A super expensive shuttle program. Four vehicles that never flew. And access to space just kept getting more expensive.

Only when every effort in the aerospace industry is focused on making itself more competitive will we see the kinds of technical advancements this new DARPA program wishes to achieve.

Newly released emails provide more evidence that IRS official Lois Lerner was lying when she said the IRS scandal was confined to the low-level employees in Cincinnati.

Working for the Democratic Party: Newly released emails provide more evidence that IRS official Lois Lerner was lying when she said the IRS scandal was confined to the low-level employees in Cincinnati.

An IRS official blasted Lois Lerner for her attempt to blame the agency’s targeting scandal on low-level employees in Cincinnati, according to newly released emails. “Cincinnati wasn’t publicly ‘thrown under the bus’ (but) instead was hit by a convoy of Mack trucks,” wrote Cindy Thomas, former director of the IRS exempt organizations office in Cincinnati, in a May 10, 2013 email to Lerner obtained by the House Ways and Means Committee.

Thomas wrote the email on the very day that the IRS targeting scandal broke when Lerner, a senior agency official based in Washington, D.C., admitted that her exempt organizations division engaged in improper targeting of conservative groups.

The truth was that the low-level employees in Cincinnati were getting their orders to harass conservatives from high up the chain in Washington.

The Census Bureau apparently faked the unemployment numbers prior to the 2012 election to make it appear more people were employed.

Working for the Democratic Party: The Census Bureau apparently faked the unemployment numbers prior to the 2012 election to make it appear more people were employed.

In the home stretch of the 2012 presidential campaign, from August to September, the unemployment rate fell sharply — raising eyebrows from Wall Street to Washington. The decline — from 8.1 percent in August to 7.8 percent in September — might not have been all it seemed. The numbers, according to a reliable source, were manipulated.

And the Census Bureau, which does the unemployment survey, knew it. Just two years before the presidential election, the Census Bureau had caught an employee fabricating data that went into the unemployment report, which is one of the most closely watched measures of the economy. And a knowledgeable source says the deception went beyond that one employee — that it escalated at the time President Obama was seeking reelection in 2012 and continues today.

Dukakis and the tank.

Dukakis and the tank.

An excellent article on what is probably one of the worst photo-ops ever attempted by a political campaign. My one disagreement is how the article focuses on how silly Dukakis looked in the helmet. This wasn’t what made the photo-op a disaster. What really made it fail was how absurd it was for him to think that riding in a tank would make people forget his deep and longstanding opposition to the military. Watch the Reagan campaign’s response ad, which used the tank ride to point this out. This is what made the photo-op a failure.

An Obamacare supporter begins to see the light.

An Obamacare supporter begins to see the light.

None of the surprising disasters he describes should have been a surprise to him, but for the fact that he likely considered any criticism in 2010 of Obama or Obamacare by his conservative friends pure racism and not worth listening to. Thus, he never heard them tell him that these disasters were exactly what was going to happen.

Will he change his voting allegiances come November? I doubt it. Too many of the liberal voters I have met in my life are downright bigoted when it comes to politics. To them, Democrats are “the good people who protect the weak and poor” while Republicans are “the evil racists who want to starve little children.” With this simplistic view of the world, they are generally unable to consider the possibility that they have this wrong.
