Planetary scientists reject meteorite fossil paper — without reading it

9:47 pm

Richard Kerr of Science is attending the annual Lunar and Planetary Science Conference in Texas, and has written a short article describing the reaction of planetary scientists to the meteorite fossil paper by NASA scientist Richard Hoover. Their reaction, hostile and disinterested, isn’t pretty. These two quotes will give you the flavor:

Whether they have closely examined the paper by astrobiologist Richard Hoover of NASA’s Marshall Space Flight Center or only heard about it in the hallways, the reaction is the same: not again.

Rather than taking a look themselves, researchers have other things in mind. One leading scientist half-jokingly suggested hanging Hoover in effigy in the conference center lobby.

Has a NASA scientist discovered alien fossils in several meteorites?

10:09 am

alien fossil?

Very very intriguing: A NASA scientist has claimed in a peer reviewed paper the discovery of alien fossils in several meteorites recovered on Earth. From the paper’s last paragraph:

The absence of nitrogen in the cyanobacterial filaments detected in the CI1 carbonaceous meteorites indicates that the filaments represent the remains of extraterrestrial life forms that grew on the parent bodies of the meteorites when liquid water was present, long before the meteorites entered the Earth’s atmosphere.

The news article describing this discovery is a bit more breathless in style than I would like, and makes me suspicious about these results. Moreover, that NASA held no press release or press conference for a result of this significance gives me pause. (Though NASA might have felt burned from the reactions they got from the arsenic-based-biology press conference and decided therefore to take a low profile here.)

More press release journalism,
this time about sunspots

10:01 am

Did you hear the news? Scientists have solved the mystery of the missing sunspots!

You didn’t? Well, here’s some headlines and stories that surely prove it:

The trouble is that every one of these headlines is 100 percent wrong. The research, based on computer models, only found that when the plasma flow from the equator to the poles beneath the Sun’s surface slows down, the number of sunspots declines.

The caves of Copernicus
and the Ocean of Storms

2:37 am

The discovery of new caves on the Moon keep coming. Today I have two new stories. The first is a discovery by professional scientists of a giant lava tube cave in the Oceanus Procellarum or Ocean of Storms. The second is the detection of a plethora of caves and sinks on the floor of the crater Copernicus, found by a NASA engineer who likes to explore the gobs of data being accumulated by Lunar Reconnaissance Orbiter and made available to all on the web.

The image below of the Moon’s near side, taken by India’s Cartosat-2A satellite and taken from the science paper, shows the location of lava tube in Oceanus Procellarum (indicated by the red dot) and the crater Copernicus.

The Moon's near side, annotated

First the professional discovery. Yesterday, the Times of India reported the discovery of lava tube more than a mile long on the Moon. I did not post a link to the article because I didn’t think the news story provided enough information to make it worth passing along. Today however, fellow caver Mark Minton emailed me the link where the actual research paper could be downloaded [pdf]. This I find definitely worth describing.

Another climategate whitewash

4:12 pm

The inspector general of the Department of Commerce has just issued a review of NOAA’s response to the climategate emails and has essentially given the agency a clean bill of health. You can download the full report here [pdf].

It’s. just. another. whitewash. Let me quote just one part of the report’s summary, referring to a Freedom of Information Act (FOIA) request to NOAA in June 2007 in which the agency responded by saying they had no such documents:

The squealing of a former Bush science administrator

11:23 pm

The cries and squeals are now coming from all sides: A former undersecretary for Science in the Energy Department during the Bush administration, Raymond L. Orbach, has joined the chorus of scientists whining about the House’s proposed cuts. [His full editorial, available here as a pdf, can only be downloaded if you subscribe to Science.]

Like all the other squealers, he admits that “the budget deficit is serious.” Nonetheless, the idea of cutting his pet science programs remains unacceptable.

It is when I read stuff like this that feel the situation is most hopeless. Is there no one willing to accept the reality that if we don’t start gaining some control over the federal budget the country will go bankrupt and we will not be able to afford anything?

Instead, all I hear are cries of “Cut! Cut! But don’t cut my program!”

How leftwing journalists lie

6:28 pm

Oink! The Washington editor for Bloomberg today demonstrated to all the dishonest way liberal journalists like to cover the budget debates in Congress.

In an opinion piece for Bloomberg, editor Albert Hunt says that the Republican cuts to the budget threaten the American lead in science. According to him, “House Republicans want to cut NIH funding for the current year by more than $1 billion, to $29.5 billion.” Because of this cut would “future advances in areas like brain science are especially threatened.”

Holdren of the Obama administration:
Deniers no, Ignorant yes!

7:14 pm

The following story is why the advocates of global warming are losing the debate: At House hearings yesterday, Obama’s science advisor John Holdren admitted that using the term “deniers” to describe scientists who had doubts about global warming is inappropriate. “It was not my intent to compare them to Holocaust deniers, and I regret it,” he replied. “In the future I will find other terms to use.”

Sounds good, doesn’t it? Shortly thereafter, however, during the same hearing, Holdren then said this about a list of 100 climate scientists [word file] who remain skeptical about global warming:

“I haven’t seen the list,” Holdren began. “But in the past, most of the names on such petitions have turned out not to be climate scientists, and one could assume that they had not spent much time reviewing the literature.”

Without any knowledge, he slams these scientists, accusing them of being ignorant of the science.

The future ups and downs of government spending in space

8:55 pm

A new report says that government spending on space will flatten worldwide over the next five years. Some key quotes from the news story however suggest all is not going downhill:

A total of 692 satellites will be launched by governments in the coming decade, up 43% from the previous decade. This is a direct reflection of the increasing number of new space-capable countries across the globe. Civil agencies will launch roughly 75% of these satellites, a significant increase compared to the last decade during which they accounted for 67% of all government satellites launched.

Also, while certain areas will show a decline (the U.S. manned program) others appear robust.

Access to space (launch capability) investments reached $4.6 billion in 2010, and should be sustained in the coming years as more governments see independent access to space as a top priority of their space programs.

In both of the above examples, the areas where space activity will increase is because of the arrival of new space-faring nations (India, Japan, China to name only the most obvious), what I have been calling the new colonial movement. I also believe that as these new countries begin to show their stuff in space, their success will further fuel the competition, and the older space-faring nations will come back to life in order to stay in the game.

A potential landing site for next Mars rover

3:32 pm

This week’s release of cool images from Mars Reconnaissance Orbiter included the color image below of a region on the floor of Holden Crater, one of the four possible landing sites for Curiosity, the Mars Science Laboratory planned for launch later this year. (If you want to see the entire image at higher resolution, you can download it here.)

Two things that immediately stand out about this image (other than this looks like an incredibly spectacular place to visit):

A retraction

11:02 am

Concerning Obama’s proposals for NASA’s 2012 budget, a closer look by me since yesterday has caused me to reconsider my earlier post. I think I spoke too soon, before I had time to review the Obama budget proposal entirely.

Though the Obama administration has pulled back somewhat from its initial 2011 budget proposals for commercial space, it does appear that they are not abandoning that effort as I had thought at first. Their 2012 proposal ($850 million per year) is still significantly higher than what Congress had authorized ($500 million), which suggests a willingness to fight for this program.

As for the program-formerly-called-Constellation, however, it does appear that this pork program is going forward. Instead of trying to cancel it like last year, the administration now appears to have become resigned to its existence, and this year includes significant funds for its construction.

Regardless, considering the insane state of the federal deficit, it seems to me both unrealistic and foolish to fund either of these programs at this time. Pork politics unfortunately will probably help keep alive the funding for the program-formerly-called-Constellation, while the lack of a powerful constituency for commercial space leaves these subsidizes very vulnerable to Congressional trimming.

A clarification of the Obama NASA manned space budget

4:07 pm

To avoid confusion, I want to clarify why I consider Obama’s commercial space budget proposal today to be a decrease, not an increase, from past budget proposals. The history of this budget goes like this:

  • In February 2010 Obama proposed to spend $1 billion per year on new commercial space.
  • Congress responded by reducing that budget to $312 million for 2011 and $500 million per year thereafter.
  • The new Obama budget for 2012 proposes to spend $850 million per year for commercial space, more than presently authorized by Congress but less than proposed by Obama only last year.

It is almost certain that Congress will trim these numbers. Meanwhile, the amount of money to the program-formerly-called-Constellation goes up.

A victory for aerospace pork

1:52 pm

Update: See my partial retraction here.

The NASA budget announced today by the White House proves how right I was when I stated back on July 8, 2010 that I had no faith in Obama’s new-found commitment to private commercial space. The new budget reduces the funds for private commercial space while putting the bulk of its support behind the unbuildable program-formerly-called Constellation. First read what I wrote in July:

The problem is that I simply do not believe the Obama administration. Everything I have learned about the current President, including the specifics (or lack thereof) of his proposal, tells me that none of his promises are going to be fulfilled. » Read more

The Sun’s continuing wimpiness

12:30 pm

Get those winter coats out of storage! Yesterday NOAA’s Space Weather Prediction Center published its monthly update of the Sun’s sunspot cycle. I’ve posted the newest graph below, showing the continuing slow rise in sunspots (blue/black lines) in comparison with the consensis prediction made by the solar science community in May 2009 (red line).

Though the sunspot count made a slight recovery in January, it was not enough to make up for the plunge in December. Essentially, the Sun continues to act like a sleepy kitten that really doesn’t want to wake up. This suggests that even the newest and wimpiest prediction for the next solar maximum, from solar scientists at the Marshall Space Flight Center, is still overstating the Sun’s upcoming sunspot activity.

In the past a wimpy Sun has been linked to cold weather, for reasons that scientists as yet don’t quiet understand. And this next solar maximum continues to look like the wimpiest in more than 200 years (see the graph on this page)!

The underground Moon

1:03 pm

More images of lunar cave pits have been posted by the scientists of Lunar Reconnaissance Orbiter (LRO). They have also published their first paper [pdf] about these cave pits for the 2011 Lunar and Planetary Science Conference taking place in March. The paper summarizes, with images, what is know about the three pits on the Moon that have each been imaged a number of times at different angles and lighting situations.

Sand dunes and dry ice on Mars

12:07 pm

Time for some more sightseeing on Mars. A recent news release from Mars Reconnaissance Orbiter noted the discovery of seasonal avalanches on Mars. This new image of the northern martian sand dunes illustrate again how the surface of Mars changes seasonally. The white patches on the ridges of the sand dunes is frozen carbon dioxide, dry ice that condenses on the crowns of the dunes every winter. When spring comes, the dry ice evaporates, and as it does so it disturbs the underlying sand, which then tumbles down the sides of the dunes, producing the dark streaks.

Ice-capped sand dunes

The process is less dramatic, however, than the avalanches seen in the previous news release, as suggested by this image below, showing the same dunes in summer without the dry ice. The dark streaks in the second image are not significantly different from the first, indicating that the process that forms them is slow and subtle.

Remembering Boris Yeltsin

1:15 am

A monument to Boris Yeltsin was unveiled today in his hometown on the 80th anniversary of his birth.

In this week of memorials to American space tragedies, this event in Russia brings to mind the far more important and significant events, affecting millions of people worldwide, that unfolded in the Soviet Union during the late 1980s and mid-1990s. The communist superpower was collapsing, and there was the real possibility that that collapse could lead to worldwide war and violence.

Yeltsin, far more than any other man, helped shepherd the former Soviet Union out of that chaos, and he did it as a civilized man, with relatively little bloodshed. As he shouted defiantly as he stood on a tank in front of the Russian parliament building on the day of the August coup, “Terror and dictatorship . . . must not be allowed to bring eternal night!”

Unlike many former communist leaders, Yeltsin had the openness of mind to recognize that the state-run centralized command society that he had grown up in and had helped run for years simply did not work. “We have oppressed the human spirit,” he noted sadly during a press conference shortly after the coup. More importantly, he also had the courage to take action on this realization, and force the painful changes that were necessary to save his country.

Yeltsin was no saint, and the Russian transition from dictatorship to freedom was far from perfect. No one even knows if that transition is going to hold, today, twenty years later. Nonetheless, the world should remember Yeltsin for his success, and honor that memory.
