When you compare the Earth’s magnetic fields with those of Mars you begin to understand why our planet is truly such a magic place. Life could be prolific in our universe but it takes a very special set of circumstances for it to thrive. In order for life to not just exist but to thrive some of the things it needs include right temperature, a source of food, energy, water, air, and the protection from radiation and solar winds that our magnetic field provides. You cannot underestimate how important this protection is. Our planets atmosphere is reliant on the electric dynamo that lives at the center of our planet. The spinning iron core generates a huge electric current which in turn creates our magnetic shield. Without it the solar winds would slowly scour our atmosphere away until there was nothing left. Taking our water with it. If you look at Mars you can see the end result. At one time Mars was more than a little Earth like. It had large amounts of liquid water, [...]

History Repeats itself….sigh NASA held a news conference today to reveal what one of the program scientists said was an announcement “for the history books”. Well……..if the history books are about how history repeats itself then they are right. NASA announced the findings in this NASA Press Release that they have found The lander found water and one-carbon organics. The water seen by SAM does not mean the drift was wet. Water molecules bound to grains of sand or dust are not unusual, but the quantity seen was higher than anticipated. SAM tentatively identified the oxygen and chlorine compound perchlorate. This is a reactive chemical previously found in arctic Martian soil by NASA’s Phoenix Lander. Reactions with other chemicals heated in SAM formed chlorinated methane compounds — one-carbon organics that were detected by the instrument. The chlorine is of Martian origin, but it is possible the carbon may be of Earth origin, carried by Curiosity and detected by SAM’s high sensitivity design For those of you old enough you may remember Viking also found signs of organics/life in it’s [...]
Smallest Recorded Amount of Summer Arctic Ice Ever Still don’t think global warming is real? The Arctic Ocean appears to have reached its annual summertime minimum ice extent and broken a new record low on Sept. 16, as reported by the National Snow and Ice Data Center. NASA and the NASA-supported NSIDC analysis of satellite data at the University of Colorado in Boulder showed that the sea ice extent shrunk to 1.32 million square miles (3.41 million square kilometers). The new record minimum measures almost 300,000 square miles less than the previous lowest extent in the satellite record, set in mid-September 2007, of 1.61 million square miles (4.17 million square kilometers). For comparison, the state of Texas measures around 268,600 square miles. NSIDC cautioned that, although Sept. 16 seems to be the annual minimum, there’s still time for winds to change and compact the ice floes, potentially reducing the sea ice extent further. NASA and NSIDC will release a complete analysis of the 2012 melt season next month, once all data for September are available.
