An international team of astronauts recently completed a six day underground cave mission
An international team of astronauts recently completed a six day underground cave mission in an effort to simulate some of the aspects of space exploration on another world.
I, along with my cave exploration friends, find this article somewhat humorous, as these astronauts weren’t doing anything that unusual from our perspective. Routinely we have teams going underground for three to five days to do exploration and survey work as part of the Germany Valley Karst Survey in West Virginia. The result has been more than fifty miles of virgin passage in the past eight years.
But, if these astronauts want to join us and do some exploration, they’d be welcome!

Finally some substance in the Presidential campaign
Up until tonight I had not watched any of the Republican Presidential debates. To me, the game show formats of each debate were such that I had no expectation of seeing any substance. Quick one-liners and gotcha attacks — the only thing that generally comes from these formats — can’t tell me anything about the deeper philosophical underpinnings of each candidate. And without that knowledge I can have no idea whether or not the candidates will follow through with what they say they’ll do.
Tonight however I did watch the Herman Cain-Newt Gingrich debate, which CSPAN has made available to watch in its entirety. The format was basically Cain and Gingrich for an hour and a half, answering a variety of questions about the three big entitlement programs, Medicare, Social Security, and Medicaid. Each man could essentially take as much time as he desired to say what he wanted.

An inside look at NASA bureaucratic madness
An inside look at NASA’s bureaucratic madness.
Much of the time NASA appears to be a loose confederation of 10 quasi independent fiefdoms, each pretty much in charge of their own business. People often ask me what would I do if I were king of NASA for a day. They expect me to say something like: build this rocket, launch that satellite. Rather I think how I would standardize the procurement processes, or the human resources procedures, or the engineering standards used across the agency. But then I always was a dreamer, tilting at impossible windmills. Launching rockets is easy; getting engineers to agree on standards is hard.
And people wonder why I strongly oppose NASA’s heavy-lift rocket (which I think will never get built), or worry that NASA’s interference will choke to death the new independent commercial space companies.

The first in orbit tests of Robonaut halted because the robot did not carry out its commands as expected.
HAL lives! The first in-orbit tests of Robonaut were halted today on ISS because the robot did not carry out its commands as expected.
NASA robot operator Phil Strawser said joint movements in the weightless space environment have proven to be different than those performed in normal gravity on Earth. Consequently, software used to operate the robot needs to be “fine-tuned,” he said.

Russia heads for Mars
Russia heads for Mars: a detailed look at the Phobos/Grunt sample return mission, set to launch on November 8.
I really wish the Russians good luck with this project. Not only would it herald their return to planetary science since the fall of the Soviet Union, success here would break their long string of failures to the red planet. Though their unmanned planetary program had some remarkable achievements during the Soviet era, of the 19 missions they flew to Mars in the 1960s, 1970s, and 1980s, all were failures, producing almost no useful data.

A NASA senior review of all planetary missions?
Here’s a tidbit I just spotted on the EPOXI (formerly Deep Impact) status website, buried in a November 1, 2011 update::
Meanwhile, NASA has decided that there will be a senior review of all operating planetary exploration missions. That will likely include a review of the status of the Deep Impact Flyby spacecraft to determine whether an additional extended mission should be approved. Decisions will not occur until early 2012.
Though Deep Impact is still a functioning spacecraft in orbit around the sun, up until this notice I had not heard of any plans to use it again after its flyby of Comet Hartley-2 in 2010. However, there is no reason its cameras could not be used for astronomy, though unfortunately its high resolution camera has a focus problem which prevents it from taking the sharpest images.
However, the timing of this review of planetary missions, combined with the story last week that the Obama administration might end all funding for future planetary missions, is intriguing. I wonder if they are tied together in some way. That the notice above says the decision will be made in “early 2012” — the moment when the Obama administration will unveil its 2012 federal budget recommendations — strongly suggests that they are linked.
Could that the administration be thinking it can salvage the bad press it will receive for shutting down all future planetary missions by spending a small amount on extending missions already in space? Or is this planetary review another indication that the rumors are true and the administration plans to end the planetary science program entirely?
Unfortunately, I am speculating here, without any real information. Stay tuned to find out.
Robot obstacle course
An evening pause: The robot obstacle course at the 2006 ROBO-ONE competition in Kawasaki, Japan. Very impressive, for a machine, though this does illustrate how difficult it is to artificially duplicate what life does so naturally.

The global output of atmospheric carbon dioxide jumped in 2010 by the biggest amount on record, according to the U.S. Department of Energy
The global output of atmospheric carbon dioxide jumped in 2010 by the biggest amount on record, according to the U.S. Department of Energy.
In 2007 when the Intergovernmental Panel on Climate Change issued its last large report on global warming, it used different scenarios for carbon dioxide pollution and said the rate of warming would be based on the rate of pollution. Boden said the latest figures put global emissions higher than the worst case projections from the climate panel.
And yet, the global temperatures are not rising, as also predicted by those same IPCC models.

A new study has been released detailing the vision problems experienced by astronauts on space flights longer than six months
A new study has been released detailing the vision problems experienced by astronauts on space flights longer than six months. Hat tip to Clark Lindsey.
The visual system changes discovered by the researchers may represent a set of adaptations to microgravity. The degree and type of response appear to vary among astronauts. Researchers hope to discover whether some astronauts are less affected by microgravity and therefore better-suited for extended space flight, such as a three-year round trip to Mars.
In their report, Drs. Mader and Lee also noted a recent NASA survey of 300 astronauts that found that correctible problems with both near and distance vision were reported by about 23 percent of astronauts on brief missions and by 48 percent of those on extended missions. The survey confirmed that for some astronauts, these vision changes continue for months or years after return to Earth.

Sailing to Mars
With the end of the Mar500 simulated mission this coming Friday, the Russians are now proposing an eighteen month simulated Mars mission on board the International Space Station.
The Russians have been pushing to do this on ISS for years. Unfortunately, NASA has always resisted.
Yet, as I wrote in Leaving Earth, we will never be able to send humans to any other planets until we have flown at least one simulated mission, in zero gravity in Earth orbit, beforehand. Wernher von Braun pointed out this reality out back in the 1950s, and that reality has not changed in the ensuing half century. Not only will such a mission tell us a great deal about the medical issues of living in weightlessness for years at a time — issues that are far from trivial — it will give us the opportunity to find out the engineering problems of building a vessel capable of keeping humans alive during interplanetary flight, far from Earth.
