The Uncertainty Monster

6 Comments

Thoughts from Judith Curry on the current state of knowledge in climate. The warm mongers never consider the possibility that their proposed cures may in fact be worse than the disease. I personally think it’s nuts to consider climate a greater threat to humanity than poverty, and particularly energy poverty. But then, many of them don’t really care about humanity, or consider humanity a problem in and of itself.

OPEC

2 Comments

Here’s your feel-good story of the day: The cartel lost $76B last year due to U.S. fracking.

I’m old enough to remember when Barack Obama told us we couldn’t drill our way out of the energy crisis. Oil reserves continue to climbe every year, as they have for decades.

Sort of related: Three reasons natural gas prices may be headed higher.

We just put in a soaking tub in our renovated bath, and now our 40-gallon water heater isn’t quite up to the job. I’d been thinking about putting in an instant heater in the bath, but there’s no gas line to it, and at California prices, the electric bill would be a killer. I could replace it with an instant-gas heater, but I’m starting to think maybe just get a bigger tank, given that it’s almost thirty years old.

OPEC is dead.

It’s been a feature of my life for forty-five years. It’s not quite as big a victory as ending the Cold War, but good riddance.

NASA And The GAO

20 Comments

The latest major project assessment is out:

Three of the largest projects in this critical stage of development—Exploration Ground Systems, Orion, and the Space Launch System—continue to face cost, schedule, and technical risks. In April 2017, we found that the first integrated test flight of these systems, known as Exploration Mission-1, will likely be delayed beyond November 2018.

NASA concurred with our findings and is currently conducting an assessment to establish a new launch date. Because NASA’s assessment is ongoing, the cost implications of the schedule delay and its effect on the projects’ baselines are still unknown. However, given that these three human space exploration programs represent more than half of NASA’s current portfolio development cost baseline, a cost increase or delay could have substantial repercussions not only for these programs but NASA’s entire portfolio.

You don’t say.

Bob Zubrin isn’t happy with NASA’s current Mars plans:

During the Apollo program, the NASA’s mission-driven human spaceflight program spent money in order to do great things. Now, lacking a mission, it just does things in order to spend a great deal of money.

Why is NASA proposing a lunar-orbiting space station? The answer to that is simple. It’s to give its Space Launch System (SLS) and Orion capsule programs something to do. The utility of such activity is not a concern. As a result, nothing useful will be accomplished.

Because Congress isn’t serious.

Bob Zimmerman has some caustic thoughts on the GAO report.

[Thursday-morning update]

Bob Zimmerman isn’t happy about the cost overruns on the engine test stands. Neither am I. These aren’t the costs, they’re the overruns. On test stands for engines for a rocket we don’t need, and can’t afford to operate.

Also Ethan Siegal agrees with Bob Zubrin that a cislunar station is a waste of time and money.

[Update mid-afternoon]

NASA doesn’t have any good answers as to why the test stands were being built in Alabama. We know the answer. It’s not a good one.
