The sun remains quiet

On July 6 NOAA’s Space Weather Prediction Center published its monthly graph, showing the progress of the sun’s sunspot cycle in comparison with the consensis prediction made by the solar science community in May 2009.

July 6, 2010 Solar Cycle progression

The graph shows clearly that, despite press-release-journalism stories like this, the sun remains in a very quiet state, with the number of sunspots far less than predicted by the red line on the graph. If these trends persist (as they have for the last three years), the next solar maximum will either be much later than expected or far weaker. In fact, the upcoming solar maximum might very well be the weakest seen in almost two centuries. Note also that the prediction shown on this graph is a significant revision downward from the science community’s earlier prediction from 2007.

First photos from inside Hayabusa capsule

Update and bumped: More details have been released about what was inside the Hayabusa capsule. In total, two 0.01 millimeter particles have been found in the inner capsule, and about 10 large particles in the outer capsule.

The first photo from inside the Hayabusa capsule has been released, showing the presence of a tiny 0.01 millimeter particle. It is still unknown whether this is an asteroid particle or something captured on the return to Earth.

The law and Obama at Yucca Mountain

Apropos to the space war between Obama and Congress over the Obama administration’s willingness to ignore Congressional legislation mandating the continuing funding of the Constellation program is this story about the administration’s efforts to circumvent federal law in order to cancel the use of Yucca Mountain in Nevada as a nuclear waste site. The courts have now expressly ruled [pdf] that the Obama administration it cannot do this: the law is the law, and they have to follow it. The key quote from the legal decision:

Unless Congress directs otherwise, [the Department of Energy] may not single-handedly derail the legislated decisionmaking process.

What a concept: the President and his appointees must obey the law!

Bolden’s al-Jazeera interview, part 2

The reports of NASA administrator Charles Bolden’s al-Jazeera interview have so far focused mostly on Bolden’s claim that his “foremost” priority at NASA is to reach out to the Muslim world in order “to help them feel good about their historic contribution to science, math, and engineering.”

Though this statement is both idiotic and condescending, I don’t think it was the most idiotic thing Bolden said. Instead, I think the prize-winner is this quote near the end of the interview (at around 21:30), where Bolden describes why we need to find out the make-up of all asteroids:

Is it sand or is it metal? If it is sand we’re not really worried that much about it because it’s probably going to impact the Earth and, you know, go away. Metal would be a bad day. We could have another ice age and instead of the extinction of the dinosaurs it would be the extinction of you and me.

Asteroids made of “sand” are merely going to “go away” if they hit the Earth? I would really like to see the scientific research Bolden is relying on for this statement.

Government and the impending shortage of helium

The law of unintended consequences strikes again! We are going to run out of our supply of helium, and it is all because the government first tried to manage and control the resource in the early 20th century, and then decided in the 1990s to extricate itself from that management. For those of us following the continuing space war over NASA’s future, this story is most instructive in illustrating how difficult it is to get the government out of our lives, once we have let it in.

Bob Hope singing “Buttons and Bows”

An evening pause: Remembered mostly today for his dedication to entertaining our American troops overseas as well as his comedy movies with Bing Crosby, Bob Hope was more than this. He had one of the quickest wits of any comic in history combined with a manner that was gentle but honest. It is a shame that few comics today can put this combination together, going instead for a kind of Don Rickles-type insult humor instead. Here is Hope (with his co-star Jane Russell) in the movie The Paleface, showing that he could sing as well. The second-half of the clip shows a not-too-interesting skit with Roy Rogers and (again) Jane Russell with all three singing the same song:

Bolden interview with al-Jazeera

This interview of Charles Bolden, NASA administrator, is another example (in a long list of examples) of the clearly misplaced priorities of the Obama administration when it comes to NASA and space exploration.

The key quote is in the first two minutes of the interview [emphasis mine]:

Bolden: When I became the NASA Administrator – before I became the NASA Administrator – [President Obama] charged me with three things: One was that he wanted me to re-inspire children to want to get into science and math, that he wanted me to expand our international relationships, and third, and perhaps foremost, he wanted me to find a way to reach out to the Muslim world and engage much more with predominantly Muslim nations to help them feel good about their historic contribution to science, math, and engineering.

Though all three of these priorities (inspire kids, international cooperation, and help the Muslim world develop) sound nice, none have anything to do with space exploration. More specifically, they have absolutely nothing to do with NASA’s original charter, which was to explore the solar system and encourage the development of the American aerospace industry.

At about 9:50, Bolden then states that “We’re not going to go anywhere beyond low Earth orbit as a single entity. The United States can’t do it. China can’t do it. No single nation is going to go to a place like Mars alone.”

Gee, I wonder what international consortium put those men on the Moon? I always thought the U.S. did it alone. According to Bolden, however, that was impossible: No single nation can do anything alone beyond Earth orbit.

There are more inanities in this interview. Listen for example to his clueless discussion of solar flares at around 19:00 and his statement at 20:30 where he claims an asteroid made of “sand” poses no threat to the Earth.

With leadership like this, the future does not look good for the American aerospace industry.

Avalanches on Mars

Saturday’s weekly dump of publications from the American Geophysical Union also included a paper that showed visual proof of avalanches on Mars! In this case, the location is Russell Crater, “a large crater in the southern hemisphere that exposes a large dune field in its center.” The avalanches occur because a frost layer made up of dry ice and a little bit of frozen water builds up on the crest of the dunes. When that frost melts, dark streaks about three to six feet wide and about 150 feet long appear, flowing downhill. The scientists believe these are avalanches made up of “a mixing of sand, dust, and unstable CO2 gas.”

A complete survey of nearby sunlike stars

A very long (182 pages) and detailed preprint paper was published today on the Los Alamos astro-ph website, describing the completion of a survey of just about all the sunlike stars within approximately 82 light years of the Earth. I haven’t had time to read the whole thing, but the abstract made these notable points:

  • The study found that more the fifty percent of all sunlike stars are single stars.
  • Among double and triple systems, the bell curve for the orbital periods peaked at 300 years.
  • The more heavy elements the star has (atoms more complex than hydrogen and helium), the more likely it will have planets.
  • The very intriguing conclusion: “The fraction of planet hosts among single, binary, and multiple systems are statistically indistinguishable, suggesting that planets are as likely to form around single stars as they are around components of binary or multiple systems with sufficiently wide separations. This, along with the preference of long orbital periods among stellar systems, increases the space around stars conducive for planet formation, and perhaps life.” [You need to download the full pdf to see this quote in the unabridged abstract.]

In other words, the evidence continues to suggest that solar systems like ours are very common.

Finding underground water on Mars

For those who fantasize that Mars might still have vast underground lakes with fish, the recent data is unfortunately not encouraging. A paper published today by the American Geophysical Union suggests that if groundwater exists on Mars, it is going to be increasingly difficult to find, possibly only in the low latitudes at low elevations. These paragraphs from the conclusion of the paper say it all:

Various lines of evidence suggest that at the time of the Late Hesperian, Mars possessed a planetary inventory of water equal to a global ocean ~0.5 km deep, much of which is believed to have been stored as ground ice and groundwater in the subsurface. The potential survival of groundwater to the present-day has important implications for understanding the geological, hydrological and mineralogical evolution of the planet, as well as the potential survival of native Martian life. The two most important factors affecting the persistence of groundwater on Mars are the depth and pore volume of the cryosphere.

To date, the orbital radar sounding data from MARSIS [an instrument on Mars Orbital Express] has provided little evidence of any deep reflectors potentially indicative of subpermafrost groundwater. Here we have examined two (of several) possible explanations for this lack of evidence: (1) that subpermafrost groundwater no longer survives on Mars or (2) that groundwater is present, but that a thicker than expected cryosphere has restricted its occurrence to depths that exceed the estimated ~3 km maximum sounding depth of MARSIS.

[snip]

Which one (or combination) of explanations discussed here is responsible for the lack of deep reflectors on Mars is unknown. But our revised estimates of cryosphere depth suggest that a successful detection of subpermafrost groundwater, outside of those areas on Mars that combine low latitude and low elevation, is unlikely. In an effort to better constrain this problem, a more comprehensive investigation of the MARSIS sounding data obtained over Athabasca Valles, and four other low-elevation, near-equatorial sites, is currently underway.

Co-hosting the John Batchelor Show tonight

Tonight, from 9 pm to 1 am (EDT), I will be on the John Batchelor Show. John is off tonight, so the guest host is Simon Constable, with yours truly acting as his co-host. For my part, I’ve arranged four guests:

  • Dr. Roy Spencer, climatogist and former NASA scientist, who will discuss the recently published global warming black list as well as other climate change issues.

Then I have brought in three guests to talk about the Obama administration’s new space policy and the space war developing between the administration and Congress over the administration’s effort to cancel the Constellation program:

  • Scott “Doc” Horowitz, former astronaut and designer of the Ares rocket. He will offer his reasons for opposing the Obama space proposals.
  • Dr. Charles Lurio, space analyst and publisher of the Lurio Report. He will outline reasons to support the Obama proposals.
  • Dr. David Livingston, host of the Space Show. He will fill us in on the state of the aerospace community and what it thinks of the Obama proposals.

Each will have his own 15 minute segment to express his views. Should be a fun time tonight.

Redundancy is all

I just thought I’d note the interesting juxtaposition illustrated by my previous two posts: In one case there is a battle between Congress and the President over the future of the American manned space program, prompted by the impending shutdown of the shuttle program with no immediate replacement in sight. In the other case, the only remaining program with the capability to provide manned access to the International Space Station has a serious docking failure.

With manned spaceflight, redundancy is all important. This juxtaposition illustrates very clearly the precarious position we will be in once the shuttle is retired.

Docking at ISS of Progress freighter fails

The arrival of a new unmanned Progress freighter at ISS has gone wrong, with the freighter drifting past the station by several miles. What happened is not yet clear, but as far as I know from my research into the Russian space station program, this is the first time the automatic docking of a Progress freighter has failed this wildly. There have been some near collisions, but to miss by miles is unprecedented.

Whether they can redirect the freighter back to the station also remains as yet unknown.

Press Release Journalism

The Penn State University investigation report on Michael Mann might be a whitewash, but what is really a travesty is the way some so-called professional journalists have covered this story. First, go and read the these two news articles at the New York Times and the Washington Post. I’ll wait till you’re back.

All done? Okay. Note how both news articles say very little about the report itself, other than its conclusions. Instead, the news articles follow the same boring news formula for writing these kinds of stories:

  • First, report the conclusions in the opening paragraphs.
  • Then, follow with a quote from a supporter of those conclusions, combined with a quick very superficial summary of the controversy.
  • Top this with by another quote from a supporter, slamming the opposition.
  • Then, add for balance a single quote from an opponent. (I find it ironic and a bit hilarious that both news articles went to the same global-warming skeptic for this particular quote, suggesting that these so-called professional reporters have very limited contact with the skeptics in the scientific community.)
  • Finally, finish things off with another quote from a supporter to emphasize the correctness of the report’s conclusions.

Neither news article provides the reader with the slightest analysis of the investigation report itself. Neither bothers to describe its superficial nature and its almost obsessive desire to find Michael Mann innocent.

Finally, both news articles read as if the reporters barely read the report itself and knew little about the content of the East Anglia emails. Instead, their stories read as if they simply scanned the press releases about the report and worked from those.

Another example of press release journalism at its worst.
