“Gray Mars” and the stuff of life

Rover Curiosity’s bore hole in Mars rock, note color change from reddish to gray Scientific knowledge requires a process of confirmation, for example, scientists have believed for decades that Mars had water and may still have it either in ice form or in the underground. This belief started with observations drawn from Mars photographs from […]

New water for life: Lakes on Jupiter’s moon Europa

Europa lake formation between surface and ocean….Credit: Britney Schmidt, U.of Texas, Austin This story begins with chaotic terrain on a moon of Jupiter, Europa. Ever since the space probe Galileo zipped by this part of the solar system and recorded the most detailed pictures of the surface of Europa, astroscientists have pretty much come to […]

Mars water: What’s all the fuss?

Seventh in a series of posts inspired by ten topics in ‘Insights of the Decade’ from the December 17, 2010 special issue of Science Magazine The topics are: Inflammation, climatology, tricks of light, alien planets, the microbiome, cell reprogramming, Martian water, the DNA time machine, cosmology and epigenetics. The original articles are now behind a […]

Mars rover Spirit: Trapped but contributing to water story

Disturbed soil surrounding the Mars rover Spirit…….Credit: NASA/JPL-Caltech/Cornell A heading for this story could be: Dead Spirit reports from a moist grave. Almost technically correct but too much wordplay. The reality is more prosaic and potentially more important. The issue is water on Mars. Evidence is overwhelming that Mars had, as in two billion years […]

Published results: LCROSS lunar impact reveals scientific treasure

The hypothesis: In the shadows of deep craters that pock the south pole of the Moon there might be ever-frozen water. The experiment: Guide the final stages of the Lunar Crater Observation and Sensing Satellite (LCROSS) rocket into one of the craters and crash it into the surface, hopefully sending a plume of dust into […]

Update 2: More Moon water

Following headlines such as “Moon Has More Water than the Great Lakes” (astrobio.net) you’d think a new study by the Carnegie Institution Geophysical Laboratory (Washington D.C., USA) has the Moon – once considered one of the driest places in the solar system – to be a veritable swimming pool. Granted, more water in various forms […]

Clean water: A self-cleaning filter

Anybody who’s ever filtered water knows that the filters get dirty. Supposedly clean water comes out one side, but the other side gets coated by whatever was in the water – dirt, bacteria, algae. Sooner rather than later the filter needs to be cleaned or changed. Commercial or public filtering of water isn’t much different, […]

Update: More Moon water

Last year, in a flurry of “NASA Bombs Moon!” stories, the NASA LCROSS (Lunar Crater Observation and Sensing Satellite) project deliberately crashed into a deeply shadowed crater to kick up dust and test its contents – looking particularly for water. They found it. [SciTechStory: On the Moon or elsewhere follow the water] The quantities found […]

On the Moon or elsewhere: Follow the water

In the detective business, the standard advice is: “Follow the money.” In human space exploration, perhaps somewhat similar advice applies: “Follow the water.” This needs debate, however there are some potent arguments in favor of the notion that human (as differentiated from robotic or probe) exploration of space should go where sources of water are […]
