According to this article, the water-ice discovered at Shackleton Crater is insufficient for human settlement.

The uncertainty of science: According to this article, the water-ice discovery announced yesterday at Shackleton Crater is insufficient for human settlement.

The latest LRO data indicate “that water is not there … in a way that would facilitate human exploration,” says planetary scientist Maria Zuber, who led the team analyzing the data.

If the signatures the team saw in the soils on the crater floor do indicate water, how much water might there be? Roughly 100 gallons – enough to fill two or three residential rain barrels – spread over a surface of about 133 square miles. Leave the swim-suit at home. “This is not like Mars,” says Dr. Zuber, a professor at the Massachusetts Institute of Technology in Cambridge, in an interview. On the red planet, explorers would find thick layers of icy soil in many locations just by turning over a shovelful or two of topsoil. [emphasis mine]

This story seems to answer my question about Zuber’s participation in the water in Shackleton paper as well as the previous paper saying there is much less water on the Moon than previously believed. It also raises questions about the journalism work of many of the other stories published in the past few days, which heavily touted the possibility of water in Shackleton.

I intend to dig into this story a bit more. Stay tuned.

New data from Lunar Reconnaissance Orbiter suggests that ice may make up as much as 22 percent of the surface material in Shackleton Crater, located on the moon’s south pole.

What I find most interesting about this result is that the team leader of this paper, Maria Zuber, was also one of the co-authors of the paper I wrote about two days ago that said there was no water in Shackleton Crater.

The Moon: a desert after all?

LEND data of lunar south pole

The uncertainty of science: A new science paper, published Saturday in the Journal of Geophysical Research – Planets,, has found that there is much less water ice trapped in the permanently shadowed craters of the lunar poles than previously thought. From the abstract:

This means that all [permanently shadowed regions], except those in Shoemaker, Cabeus and Rozhdestvensky U craters, do not contain any significant amount of hydrogen in comparison with sunlit areas around them at the same latitude.

And from the paper’s conclusion:

[E]ven now the data is enough for definite conclusion that [permanently shadowed regions] at both poles are not reservoirs of large deposits of water ice.

The Lunar Orbiter image of Copernicus Crater, taken forty-six years ago, has been re-released after significant refurbishing..

Oblique image of Copernicus taken in 1966

Reboot: The Lunar Orbiter image of Copernicus Crater, taken forty-six years ago, has been re-released after significant refurbishing.

By adding modern computer interfaces and data handling techniques, the LOIRP was able to scan and record the data in ways that simply could not have been accomplished in the 1960s. As a result the images that were obtained had a much higher resolution and dynamic range than had been seen to date. Indeed, in many cases, these images often rival or exceed images taken by the Lunar Reconnaissance Orbiter which is currently surveying the Moon.

You should definitely check it out, as it is a breathtaking image. Historic too, as it was the first image from the Moon that truly made the place understandable.

If the U.S. gets a competitive private aerospace industry going — which seems increasingly likely — I’m willing to bet those companies will get to the Moon before either of these governments.

Lunar Reconnaissance Orbiter has published another spectacular oblique image of Tycho crater.

Lunar Reconnaissance Orbiter has published another spectacular oblique image of Tycho crater.

If you look closely at the slope of the mountain, you can see an avalanche trail at its center and the debris piled up at the mountain’s base.

See the first oblique image, released in June 2011, here. The two images look at the crater from opposite directions.

If there is water ice on the Moon, scientists have found that the bombardment from interstellar cosmic rays has likely caused chemical reactions that “can create complex carbon chains similar to those that help form the foundations of biological structures.”

Using its Space Launch System (SLS) and Orion capsule, NASA is aiming for an unmanned test flight around the Moon in December 2017.

Two important tidbits revealed by this article: First, the first test flight of Orion will use a Delta 4 Heavy rocket. Two, NASA hopes to have its heavy lift SLS rocket ready for the 2017 mission.

Forgive me for being cynical, but I will believe the second tidbit only when it happens.

The head of Russia’s space agency makes news again

The following stories are all the result of statements made by Vladimir Popovkin, the head of Roscosmos, the Russian Federal space agency, during a radio interview yesterday.

This is the same guy that only a few weeks ago was throwing accusations at the U.S. for the failure of Phobos-Grunt.

What should we make of these statements? First, everything Popovkin says is aimed at fund-raising. Whatever his background, he is a political appointee whose job is to generate interest and funding for Russia’s space program. Everything he says in public must be weighed against this reality. That he first tried to shift the blame to the U.S. for Phobos-Grunt’s loss was an effort to absolve his program from any blame and thus reduce the possibility that the Russian government might cut his funding. Now that his agency has gotten approval of its insurance payment for the failure, however, he is free to say otherwise.

Second, these announcements give us a clear indication of where the Russia space effort is heading, and that effort looks both thoughtful and intelligent.

Studying the Moon by starlight

The Moon's south pole by starlight

In a paper published today in the Journal for Geophysical Research, Planets, the science team for Lunar Reconnaissance Orbiter describe how they have used starlight to peer into the permanently shadowed craters of the Moon’s north and south poles. Looking only during the lunar night, they measured the dim albedo of the Moon from reflected starlight. From this very weak signal they were able to cull two interesting facts about these very cold and very dark places.

  • The ground at the bottom of these craters is more porous than the surrounding unshadowed terrain.
  • There is evidence in the spectroscopy of 1 to 2% water frost in these craters.
