Bigelow in negotiations to supply privately-built modules to ISS

12:59 pm

Bigelow Aerospace is in negotiations with both NASA and Japan to supply ISS with privately-built modules

The module could be rented out as an ISS storage unit, making the station less dependent on frequent resupply flights, says Hiroshi Kikuchi of JAMSS. To show that the modules are capable of safe, crewed operation, Bigelow is also negotiating with NASA to attach one to a US-owned ISS module.

Another Al Gore doomsday prediction bites the dust

9:31 pm

In a new paper published yesterday, climate scientists described a newly discovered deep, cold current flowing off Iceland’s coast that appears to make the ocean conveyor belt that warms the northern Atlantic less sensitive to climate change than previously thought.

In other words, another one of Al Gore’s doomsday predictions has proven false.

More significantly, scientists now have no understanding why the ocean conveyor belt shut down during past ice ages, as their most favored theory now appears insufficient.

Craters, craters, everywhere

4:13 pm

Below the fold are two images released today, one from Dawn at Vesta and the other from Messenger at Mercury. What makes them interesting to me is that, though the surfaces of both Vesta and Mercury are crater-packed, there are definitely distinct differences between them that one can spot if you look closely, all highlighting the fundamentally different environments of both worlds.

First, the Vesta photograph. The image looks out past the asteroid’s horizon, showing clearly that this dwarf planet is not spherical, with the south pole depression that puzzles scientists just on the planet’s limb. The parallel long deep grooves that are associated with this depression can be seen on the right. Notice also that the inside walls of all the craters slope downward in a very shallow manner. This gives the impression that the impacts that formed these craters smashed into an almost beachlike sandy surface. Note too the that the center of some craters have what appear to be flat small “ponds,” a phenomenon seen by the spacecraft NEAR when it orbited the asteroid Eros. These ponds are not liquid, but are actually made up of fine-grained particles that settle in the hollows of the asteroid.

NASA announces awards for three technology demonstration space missions

2:47 pm

NASA has announced three awards for technology demonstration space missions, all set to fly within four years. More details here.

The three missions are:

  • A solar sail demonstration mission, flying a sail 38 by 38 meter sail.
  • A demonstration of in-space laser/optical communications technologies.
  • The use of a high-precision atomic clock in space.

I especially like the solar sail mission because of its long range possibilities, though the other technologies would probably be put to practical use more quickly.

One man’s response to Obama’s demand that taxes on the rich be raised

10:00 pm

One man’s response to Obama’s demand that taxes on the rich be raised.

I deeply resent that President Obama has decided that I don’t need all the money I’ve not paid in taxes over the years, or that I should leave less for my children and grandchildren and give more to him to spend as he thinks fit.

and

Governments have an obligation to spend our tax money on programs that work. They fail at this fundamental task. Do we really need dozens of retraining programs with no measure of performance or results? Do we really need to spend money on solar panels, windmills and battery-operated cars when we have ample energy supplies in this country? Do we really need all the regulations that put an estimated $2 trillion burden on our economy by raising the price of things we buy? Do we really need subsidies for domestic sugar farmers and ethanol producers?

The new commercial space companies question NASA contracting policies

3:02 pm

The new commercial space companies are challenging NASA’s new contracting policy.

The article covers the conflict that I described in this post, whereby NASA is abandoning the more flexible contracting approach used for the commercial cargo contracts of SpaceX and Orbital Sciences and going instead with the contracting system it used for all past NASA subcontracts.

The article is errs badly when it calls the new contracting approach that NASA wants to use “non-traditional.” It is instead the way NASA has been doing things for decades, whereby the agency takes full control of everything and requires contractors to fill out so much paperwork that the costs double and triple.

Did Obamacare cause the economic collapse

6:56 pm

“The elephant in the room.”

By the spring of 2010, private sector job growth turned positive. In April job growth increased to 230,000 net private-sector jobs. The economy appeared on track for a normal recovery from an awful recession. The administration began confidently predicting a “Recovery Summer.” But Recovery Summer fizzled instead of sizzled. In May private sector job growth dropped sharply to less than 50,000 net jobs. Thereafter, monthly improvement in private job growth averaged just 6,500 jobs.

What else happened in the spring of 2010? Despite obstacles that many believed would kill the bill, Congress passed the Affordable Care Act. Within two months, the trend in job growth dropped sharply. Monthly job creation had been on pace to top out in the hundreds of thousands. Post-Affordable Care Act, it has barely kept pace with population growth. [emphasis mine]

The health-care measure raises business costs and makes planning for the future more difficult. It should be expected to slow hiring.

Federal Reserve officials report that the law has had exactly this effect. Dennis Lockhart, president of the Atlanta Fed, reports that “prominent among these (factors businesses explain are impeding hiring) is the lack of clarity about the cost implications of the recent health care legislation. We’ve frequently heard strong comments to the effect of ‘my company won’t hire a single additional worker until we know what health insurance costs are going to be.'” Surveys bear out these warnings. In a recent poll one-third of small business owners identified the healthcare bill as one of their top two obstacles to hiring. [emphasis mine]

66 Percent of CEOs Plan to Freeze or Downsize Workforce Size

10:13 pm

Two-thirds of the country’s CEOs plan to freeze or downsize their workforce over the next year, according to a new survey.

“As I approach my 44th year in business, the last 20 as CEO, I can never remember a time when I felt so disenfranchised from our leadership in Washington. They seem determined to continue their ongoing anti-business attitude and to frustrate small and mid-sized businesses by uncertainty on taxes, government regulations, and simply too many bureaucratic restrictions. We desperately need a change in Washington.”

I guarantee that much of this reluctance to hire stems from uncertainty and fear of Obamacare and the regulations it brings.

New images from Opportunity

7:28 pm

Opportunity begins exploring the rim of Endeavour Crater, taking a bunch of new images . I especially like this one, of which I’ve posted a cropped scaled-down version below. The image looks across the 13-mile-wide Endeavour Crater to its far rim on the horizon. Note the haze. Mars very clearly has an atmosphere, even though it is far thinner than Earth’s. In the foreground are scattered rocks, ejecta produced from the impact that formed a smaller nearby crater now named Opportunity Crater.
