The discovery of volcanoes on Io

12:39 pm

discovery image

On March 8, 1979, as Voyager 1 was speeding away from Jupiter after its historic flyby of the gas giant three days earlier, it looked back at the planet and took some navigational images. Linda Morabito, one of the engineers in charge of using these navigational images to make sure the spacecraft was on its planned course, took one look at the image on the right, an overexposed image of the moon Io, and decided that it had captured something very unusual. On the limb of the moon was this strange shape that at first glance looked like another moon partly hidden behind Io. She and her fellow engineers immediately realized that this was not possible, and that the object was probably a plume coming up from the surface of Io. To their glee, they had taken the first image of an eruption of active volcano on another world!

Today, on the astro-ph preprint website, Morabito has published a minute-by-minute account of that discovery. It makes for fascinating reading, partly because the discovery was so exciting and unique, partly because it illustrated starkly the human nature of science research, and partly because of the amazing circumstances of that discovery. Only one week before, scientists has predicted active volcanism on Io in a paper published in the journal Science. To quote her abstract:

Bankruptcy

10:20 pm

It appears that Barack Obama has won another four years in office. Despite what many consider to be one of the weakest and most incompetent presidencies in history, the American people have decided to stick with this man. Even worse, the Democrats look like they will gain seats in the Senate, even though it was the Democratic majority in that Senate that has refused to pass a budget — as required by law — for the last three years. For that dereliction of duty, the American people have decided to reward them with more power.

Overall, it appears that the polls that favored Democrats in their sampling were actually capturing the tone of the country. The public wants big government and a restriction in freedom. 2010 was a fluke, not a trend. I was wrong.

We are stuck with Obamacare. We are stuck with trillion dollar deficits. We are stuck with bankruptcy. I have little hope now for the near future. It will probably take fifty years or more to fix the problems that the past four years and the next four years will create.

This is not even a conservative perspective. No policy can survive, even good leftwing policy, when the government is bankrupt. And with trillion dollar deficits the new normal, we are guaranteed that the government will go bankrupt. And it will take everything else down with it.

Even worse, this willingness of the American public and its intellectual class to ignore this reality, to make believe that trillion dollar deficits don’t matter, suggests an intellectual bankruptcy that is even more appalling. For you can’t fix a problem if you refuse to face it.

The Sun takes a plunge

11:59 am

The latest monthly update the ongoing sunspot cycle of the Sun has been published today by NOAA. Once again, the trend suggests that the Sun’s ability to produce sunspots is fading, and fading fast.

I have posted this latest graph, covering the month of October, below the fold, with additional analysis.

Kepler reveals our Sun might be more variable than we imagine

5:13 pm

More exoplanet news: The problems of Kepler.

The article outlines the status — both good and bad — of Kepler in its hunt for Earthlike exoplanets.

I have already reported on Kepler’s failed reaction wheel. It no longer has a backup and needs every reaction wheel it has to keep it pointed in so precise a manner. Thus, the loss of one more wheel will shut the telescope down.

However, I had not been aware that the scientists now need more than twice as much time, eight years instead of three, to do their work, because they have discovered that sunlike stars are far more variable than expected. To quote the article,

The new ebook edition of Genesis

12:56 pm

I am thrilled to announce that the new ebook edition of my first book, Genesis: the Story of Apollo 8, is now officially available for sale for only $5.99 from Mountain Lake Press. The direct link to Mountain Lake Press’s sales page is here and on the right. Within two weeks the book will also be available at all retailers, but if you buy it direct from Mountain Lake Press, I will make a little extra money, which would be very much appreciated.

In creating this ebook edition I made sure that all the graphics from the original but out-of-print hardback were included. Valerie Anders, the wife of astronaut Bill Anders, added her own thoughts in a new foreword. I also added a new introduction discussing how the history of space exploration has evolved since the book’s initial publication in 1998. As I noted,

Telescopes of the future

11:27 pm

Two stories were published on Thursday about two very different future space telescopes. Both are worthwhile, but the differences between them illustrate how the industry of space astronomy — like manned space — is evolving from Big Science and government to small, efficient, and privately built.

First there is this story describing how the nonprofit B612 Foundation’s project to launch an infrared telescope by 2017 had passed its first technical review.

Polar bear fraud

2:00 pm

The scientist famous for identifying drowning polar bears in the Arctic has been reprimanded for leaking emails and following “inappropriate” procurement procedures at his job at the Department of Interior.

The investigation also criticized the scientist, Charles Monnett, for fudging his data in reporting the death of the polar bears, a report that the global warming movement used extensively to falsely prove that global warming was causing the destruction of the polar bear population.

The Nature story above tries to make light of Monnett’s misconduct, especially in connection with his polar bear report as well as his work in awarding contracts. The report itself [pdf] is far more harsh.

In connection with Monnett’s contract work, it appears he actually helped one contractor write his proposal, then sat on the board that awarded the contract to that contractor.
