Water Water Everywhere

My desire for extra-planetary emigration is well documented, so, when I saw two interesting articles about water on both Luna and Mars, I had to talk about them and their effect on bringing about the belated retrofuture.

Before I talk about the moon, I want to mention a finding that has been overshadowed by the moon finding (which, admittedly, is very very exciting.) However, Here on Between Worlds I'm going to give Mars the first billing. a few meteorites that smashed into mars last year have uncovered martian ice at latitudes much closer to the equator than we have expected to find ice. This means that ice is much more plentiful on mars than we previously thought.

What I find most fascinating about this is a coincidence that only proves that nature has a twisted sense of humor. One of the meteorites revealed ice no more than 4 inches from where the 1970's Viking 2 lander dug a trench into mars. If the viking lander had dug its trench only 3.5 inches deeper, it would have likely revealed the ice, and certainly would have changed how we view mars and martian exploration in the past 4 decades.

But onto the big story of the day, The Indian Chandrayaan-1 mission, using NASA's Moon Meteorology Mapper, has discovered that the moon is damp. Water, while not abundant, is definitively present on the moon. One of the major problems that has been facing a Lunar Colony has been the assumed dryness of the lunar surface. If we were unable to find water on the moon, we would have to ship it all up from earth, and that puts a major major crimp in any plans. the energy cost of shipping it all up is extensive to say the least (if you don't believe me, ask anyone who has gone to burning man)
 Furthermore, we gain more than just drinking water when we find water on the planetary bodies and moons we wish to colonize, Rocket-fuel and Breathable Oxygen all can be made once we have that good ol' Hydrogen Hydroxide (don't listen to the fools who call it 'dihydrogen monoxide' they don't know what they are talking about).

These findings force us to radically change our previous conceptions about the rarity of water in the solar system. The increased water we find throughout the system can and will be used to sustain human colonies on other planets.  Overpopulation has become a major problem for humanity, we can fix this in two ways, decreasing population, and increasing resources/area. However, our home planet is fast becoming tapped out of resources, so, where do we go? To the stars, where else? This is one of the major callings of our generation. We must break free from the gravity well that keeps us on this planet. The water findings just give us the confidence that allows us to take bold action in taking the next step to become the first species (so far as we know) to spread itself out to the stars.

Mathematics of Steallar Death

Applied Mathematicians and Astrophysicists at Lawrence Berkeley National Laboratory have recently created a simulation of the last few hours of a white dwarf star leading up to a type 1a supernova. regular readers (ha, check it out, I made a funny) may remember me blogging about type 1a supernova earlier in the month. So I felt some obligation to post this awesome new finding about them.

For years type 1a supernova have been a standard candle for astrophysicists because it is theorized that they all blow up the same way, however, we have until now, a good computational simulation of the creation of type 1a supernovas has seemed intractable, which begged the question, "do they really all blow up the same way? if we cant simulate it, perhaps they don't..."

But, Mathematics once again came to the rescue as applied mathematicians Ann Almgren, John Bell and Andy Nonaka of Berkeley Lab's Computational Research Division,  developed MAESTRO, a simulation code of the problem. The real genius behind MAESTRO was to strip out the sound waves making the problem much more efficient and able to run on modern day supercomputers like the Jaguar, the Cray XT4, one of the worlds most powerful supercomputers.

Panoramic Galaxy

I found over at Wired Science an awesome panorama of the the milky way galaxy. what is exceptionally cool about this is that it was made with nothing more than a digital camera, each of the over 1,200 image was taking with a 6 minute exposure and the entire panorama took months to create.

The artist, Serge Brunier deserves much applause as does Frédéric Tapissier, who solved many of the technical problems of combining all of these images into the amazing whole

This is just a beautiful image that gives one perspective into the world we live in, and the vast scope of the beyond. Also it is as good a case against light pollution that I can conceive.

Stand Aside, its time for SCIENCE

Its a great time to love science. We now have the first evidence of a binary star system where one is a massive white dwarf star. Such stars are the precursor to type 1a supernovae. A white dwarf star is usually about half as massive as the earth and about as large, however, the star the ESA has found is half the size of the earth and half again as massive, hence much much denser than the average white dwarf. The theory is that when the star hits 1.60 earth masses, it will cause a supernova, one that is close enough to us that will light up the sky day and night. The inhabitants of this planet are going to be so damn lucky in a few million years....

ScienceDaily (2009-09-04) -- The European Space Agency's XMM-Newton orbiting X-ray telescope has uncovered a celestial Rosetta stone: the first close-up of a white dwarf star, circling a companion star, that could explode into a particular kind of supernova in a few million years. These supernovae are used as beacons to measure cosmic distances and ultimately understand the expansion of our Universe.
