NASA’s costs estimates too low for Congress’s heavy-lift rocket

Surprise, surprise! An independent analysis of NASA’s budget estimates to build Congress’s heavy-lift rocket, the program-formerly-called-Constellation, are untrustworthy and likely low.

“All three program estimates assume large, unsubstantiated, future cost efficiencies leading to the impression that they are optimistic,” the team said in its key findings. A risk assessment revealed the funding reserves projected for all three programs are insufficient, according to Booz Allen Hamilton. NASA has not disclosed its internal cost estimate for the Space Launch System. “Due to procurement of items still in development and large cost risks in the out years, NASA cannot have full confidence in the estimates for long-term planning,” the executive summary said.

This project is nothing more than Congressional pork. It will never get built. Sadly, it might waste a lot of money before it never gets built.

Genesis cover

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

Earthquake in Virginia

Quake map

A 5.9 magnitude earthquake hit Virginia at about 1:51 pm (Eastern).

I am in Maryland, just outside the beltway, and felt something like an earthquake about five minutes ago. The house started to shake, then settled, then shook again. Quite startling. I opened the front door the same time a neighbor did. She had felt the same thing.

The above quake was more than 90 miles away. I wonder how bad it is there, considering the eastern U.S. rarely experiences quakes and has made no preparations for such a thing.

Bigelow in negotiations to supply privately-built modules to ISS

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

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

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

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

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

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.
