The Cassini spacecraft orbiting Saturn continues to send back a wealth of data, and some gob-smacking wonderful images. Below are two of the more recent examples. The first is not a computer-generated graphic: it shows the small moon Helene (21 miles across) during a fly-by on March 3, 2010, with Saturn’s atmosphere providing the background. The second captures Saturn’s two largest moons, with the smaller Rhea crossing in front of the larger Titan.
Who says space exploration is dead? Sometime in November researchers will conduct the first zero gravity tests of the world’s first beer to be certified for drinking in space. The tests will take place during suborbital flights of what is commonly known as the Vomit Comet. Key quote:
Sampling the beer during weightless parabolas, the flight researcher will record both qualitative data on beverage taste and drinkability and biometric data on body temperature, heart rate, and blood alcohol content.
You think NASA’s going get money this year or next? Or ever? In one graph (see below), this article shows how completely out of control federal spending has become, beginning in 2007, with no end in sight. Key quote:
Until this skyrocketing spending growth is arrested and reversed, we suspect that government spending has become disconnected from the ability of any American household to support it.
Three polls issued today make it very clear that the upcoming November elections are going to be a very different animal than any election anyone has seen in decades.
First, Public Policy Polling (PPP) finds that in the West Virginia race for the Senate seat formerly held by Robert Byrd, long shot Republican John Raese is leading shoe-in Democrat Joe Manchin by 3 points.
Second, Rasmussen finds that not only is Republican Joe Miller leading his opponents in the Alaska Senate race by 15%, the Democrat candidate, Scott McAdams, can only garner 25%. Meanwhile, Lisa Murkowski, who lost to Miller in a primary upset, is doing almost as bad as an independent write-in candidate, with 27%.
Third, a Quinnipiac poll shows Republican Tom Corbett destroying Democrat Dan Onorato by a 54-39 margin in the race for Pennsylvania governor.
Not only do these numbers show a willingness of the public to consider new and unknown candidates and reject incumbents, they also show a surprising hostility to Democrat candidates in regions that have always been considered Democrat strongholds. In West Virginia, the accepted wisdom was that the Democrat Manchin would be nominated and then annointed. Not so. In Alaska, not only did Miller upset the incumbent Murkowski in the Republican primary, voters apparently have little interest in seeing her return to office, or give her Democrat rival the job either. And in Pennsylvania, a swing state that has in recent years been swinging increasingly Democratic, the numbers show instead a complete reversal of that trend and a total rejection of the Democrat candidate.
Yes, November 2nd is going to be an interesting day indeed.
Update: Another poll released today from PPP and commissioned by the leftwing website, Daily Kos, continues these astonishing trends. In the Wisconsin Senate race, Democrat incumbent Russ Feingold now trails Republican Ron Johnson by 11% points. And in Wisconsin governor’s race, the same poll found the Republican leading by 9%.
On August 9, 2010 the camera on Lunar Reconnaissance Orbiter took some routine calibration images and captured the Earth from lunar orbit, showing the western hemisphere with relatively little cloud cover. The picture below is a tiny piece from that global image, cropped to show the United States. The details are pretty remarkable, considering the distance. You can explore the full global image in detail here.
Research results posted today [pdf] at the European Planetary Science Congress show that the methane in Mars’s atmosphere is seasonally variable and far more short-lived than predicted, disappearing in less than a year. Some process, therefore, must be both using it and replenishing it. On Earth, that’s almost always done by some form of life process. Key quote by one of the scientists, from the press release:
“Only small amounts of methane are present in the martian atmosphere, coming from very localised sources. We’ve looked at changes in concentrations of the gas and found that there are seasonal and also annual variations. The source of the methane could be geological activity or it could be biological we can’t tell at this point.”
The image below shows the three regions (in yellow) where the methane is concentrated.
On Friday I drove up to Westfield, New Jersey, to give a public lecture to Amateur Astronomers, Inc. at Union County College in Cranford, New Jersey. On this, my second visit to this amateur astronomy club, my lecture topic was the story behind the Apollo 8 mission to the Moon, the subject of my first book, Genesis: the Story of Apollo 8.
I visit a lot of astronomy clubs, giving talks on space and its history, so it is not a light complement when I say that this particular club is one of the most active, organized, and enthusiastic astronomy clubs I have ever seen. This is not to say that other clubs are not active, organized, or enthusiastic, only that it seems to me that the members of Amateur Astronomers are particularly so.
This fact only makes the decision by Union County College to throw the club and its observatory off campus seem incredibly stupid. Fortunately, the club has managed to negotiate a two year postponement of their eviction. What will happen after that, however, remains unknown.
The Washington Post today includes an excellent article outlining quite succinctly the mess that’s resulted from the space war between the House, the Senate, and the administration over NASA’s manned program. Key quote:
In an effort to restore a NASA consensus and fund future human space travel, negotiators from the House and Senate have been meeting frequently in recent weeks. Participants say, however, that the sides are dug in and that stalemate is a real possibility.
As I have been saying for months, don’t expect anything good to come from Congress, even if they come up with a compromise. Obama and NASA under Bolden did a very bad job selling their ideas to Congress, and Congress returned the favor by rejecting those ideas and instead coming up with two different plans, both of which serve their own parochial interests rather than the nation’s. The result is a micromanaged mishmosh that won’t get anything done, while wasting huges sums of cash that the federal government does not have.
It appears that the Arctic icecap has reached its 2010 minimum. Though the icecap extent in the spring was the largest since 2002 (see image below), the melt was fast and the minimum appears to be the third lowest since 1979.
Does this mean the icecap is melting and will disappear shortly, as some politicians like to believe? Hardly. Though the data suggests a long term decline in ice extent, recent trends also show evidence that the icecap might be recovering. What will actually happen is still anyone’s guess.
Bumped, with update below
This Christian Science Monitor article gives a nice summary of the present state of war between the President, the House, and the Senate over NASA’s future.
All in all, things do not look good. With so much disagreement, whatever Congress and the President eventually agree to is going to be a mess, accomplishing little while spending gobs of money that the federal government simply no longer has. The result will almost certainly be a failed NASA program, an inability of the United States government to get astronauts into orbit, and an enormous waste of resources.
The one shining light in all this is that we still have a unrelenting need to get into space, not merely to supply the International Space Station but to also compete with other nations. It is my belief that this need — and the potential profits to be made from it — is going to compel private companies to build their own rockets and capsules for getting humans and cargo into space. And I think they will do it whether or not the federal government can get its act together.
Thus, though the U.S. might find itself a bystander in the space race for the next decade or so, in the end we will have a vibrant, competing aerospace industry, capable of dominating the exploration of the solar system for generations to come.
So buck up, space cadets. The near term future might be grim, but the long term possibilities remain endless.
Update: This announcement today from Boeing and Space Adventures illustrates my above point perfectly. For decades Boeing has been a lazy company, living off the government dole while doing little to capture market share in the competitive market. Now that the dole of government is possibly going away, however, the company at last appears to be coming alive. Instead of waiting for a deal with NASA, Boeing has been going ahead with its CST-100 manned capsule, figuring it can make money anyway by selling this product to both private and government customers.
This breath-taking image of Saturn and its rings was taken by Cassini on July 19, 2009 and posted on the Cassini image gallery on August 27, 2010.
There is a lobbying push among a lot of space activists to get the House NASA authorization bill changed so that more money is spent for commercial space. Unfortunately for these activists, reality is about to strike (almost certainly on November 2). Also see this story: Our debt is more than all the money in the world.
With a new Congress almost certainly dominated by individuals who want to shrink the size of government, I doubt anyone in the space industry is going to get much of what they want in the coming years.
Two stories from the so-called “city of brotherly love”:
First, a woman whose son was murdered decided she needed to protect herself. She legally obtained a concealed carry permit and purchased a gun, only to have the police come to her home, arrest her, and confiscate it. Key quote:
“I thought they were coming to my door to tell me they had my son’s murderer,” [the woman] said. “But they were coming to take me and my gun, and now I’m defenseless.”
In the second story, it appears that Philadelphia police are making a policy to arrest security guards and confiscate their guns, even though the guns were lawfully obtained and legally permitted. At least nine different security guards have experienced this form of Philadelphia thuggery. Key quote from Lieutenant Fran Healy, special adviser to the police commissioner:
“Officers’ safety comes first, and not infringing on people’s rights comes second.”
By the way, Philadelphia is the same city that now wants to charge a $300 business license for anyone writing a blog, regardless of whether they are running a business or hobby, and thus effectively stifling free speech.
This amazing Hubble image, showing a strange spiral to the left of the bright star, is not of a galaxy. Instead, it is a binary star system where the material from one star is being sucked away from it by the other, thus producing the spiral pattern.
What is most fascinating about this discovery is that this kind of phenomenon has been predicted for decades, by both astronomers and science fiction writers. Consider for example this quote from Larry Niven from his short story, The Soft Weapon, where he describes what he thinks the binary star Beta Lyrae might look like:
There was smoke across the sky, a trail of red smoke wound in a tight spiral coil. At the center of the coil was the source of the fire: a double star. One member was violet-white, a flame to brand holes in a human retina, its force held in check by the polarized window. The companion was small and yellow. They seemed to burn inches apart, so close that their masses had pulled them both into flattened eggs, so close that a red belt of lesser flame looped around them to link their bulging equators togehter. The belt was hydrogen, still mating in fusion fire, pulled loose from the stellar surfaces by two gravitional wells in conflict.
The gravity did more than that. It sent a loose end of the red belt flailing away, away and out in a burning Maypole spiral that expanded and dimmed as it rose toward interstellar space, until it turned from flame-red to smoke-red, bracketing the sky and painting a spiral path of stars deep red across half the universe.
If you are a baby boomer who grew up in the 1960s, such as myself, there are some very safe assumptions that anyone can make about your history and political views, both during the 1960s and the decades that followed.
For example, in the 1960s you were almost certainly against the Vietnam War. You were also likely to oppose President Lyndon Johnson and his Vice-President Hubert Humphrey. You cheered Eugene McCarthy’s anti-war campaign for President, and you probably also despised President Nixon and passionately wished that George McGovern had won the 1972 Presidential campaign.
Almost certainly you participated in some anti-war protests somewhere during the 1960s. Some of you were in Chicago for the protests during the Democratic National Convention in 1968, while others were likely to have participated in the numerous university sit-ins that were rampant throughout the country in the late 1960s.
Sadly, many of you at that time would have probably considered the police “pigs” and the military “evil” (even if those insults seem totally unfair, disgusting, and almost unforgivable to you now).
On a personal level, you probably experimented with drugs, had fun with rock ‘n roll, and even more fun with sex. Many of you also probably participated in the hippie culture at events like Woodstock and places like San Francisco and the Lower Eastside of Manhattan.
Above all, you abhorred authority. You were raised to be very independent-minded and » Read more
Profile in courage: Danish cartoonist Kurt Westergaard was given an award in Germany yesterday at a freedom of the press conference. Key quote:
“It does not matter if we think his cartoons are tasteful or not, if we think they are necessary and helping or not,” [German Chancellor Angela] Merkel said at the ceremony in the city of Potsdam. The question, she said, was, “Is he allowed to do this? Yes, he is.”
Westergaard’s drawing is below. Though it might offend some, the drawing of a cartoon is never justification for violence. That so many Muslims seem to think their religion justifies such violence, however, tells us a great deal about the nature of that religion.
On August 18, 2010, the Mars rover Opportunity took this panorama image of the Martian terrain. Up close, patches of bedrock can be seen where the sand had blown clear. In the far distance the rim of Endeavour Crater, the rover’s long term destination, pokes up over the horizon.
Update: A press notice from JPL today notes that Opportunity has now traveled about half of the 11.8 mile distance to Endeavour Crater. As it took two years to go this far, the journey still has two years to go, assuming the rover survives that long.
The Sun continues to show a reluctance to come out of its solar minimum. Today NOAA’s Space Weather Prediction Center published its monthly graph, showing the sun’s developing sunspot cycle in comparison with the consensis prediction made by the solar science community in May 2009. As you can see below, actual sunspot activity remains far below what was predicted by the red line.
As I noted when I posted the July and August graphs, the Sun’s ramp up to solar maximum continues to be far slower and weaker than predicted. After two hundred years of watching a vibrant and strong solar cycle, it appears increasingly likely that we are heading towards some quiet time on the Sun.
The chart below, found here, shows current worldwide military spending as a percentage of GDP. The redder (or darker) the color, the higher the spending.
What does this tell us about Islam and the Islamic world?
The Lunar Reconnaissance Orbiter has released another lunar cave image, this time showing a double pit entrance with a natural bridge between them. [Thanks to reader James Fincannon for the tip.]
From the caption: “The bridge is approximately 7 meters wide on top and perhaps 9 meters on the bottom side, and is a 20 meter walk for an astronaut to cross from one side to the other.”
