Erupted on the Moon<br><br>On July 16, 1969, Commander Neil Armstrong, Lunar Module Pilot hogan outlet sito ufficiale Buzz Aldrin and Command Module Pilot Michael Collins launched atop a Saturn V rocket toward the moon. The 8 day NASA jordan pas cher mission captivated the planet as Armstrong and Aldrin explored the lunar surface michael kors outlet store on July 20, supported by Michael Collins who orbited overhead. 46 years after the first cheap ghds online store successful hogan outlet 2015 landing of the Apollo program, we've dug into the NASA archives to find some familiar and some not so familiar views of the Apollo hogan outlet roma 11 mission.<br><br>"The lunar volcanic glasses are thought to be the product of fire fountain eruptions, in which a jet of basaltic lava erupts through a vent, spattering droplets of lava that cool quickly to form glass," Bruno Scaillet, with the air max pas cher University chaussure nike tn of Orleans in France, wrote outlet woolrich online in michael kors outlet an hogan outlet article in this week's Nature Geoscience.<br><br>The process is similar to shaking a can of soda and taking off the cap.<br><br>On Earth, the gas that triggers fire fountains is typically carbon dioxide or water.<br><br>The new analysis of the lunar samples showed that concentrations of carbon and water decreased toward the center louboutin chaussures soldes of the beads, an indication of degassing. Follow on studies with computer models show the fire fountains were most likely fed by carbon monoxide gas.<br><br>PHOTOS: Moonwalkers: Stunning Photos from Apollo 11<br><br>"It mbt outlet roma was debated it could sac michael kors imitation be carbon monoxide, but there giuseppe zanotti basket was no evidence," Brown University lunar sac longchamp solde scientist Alberto Saal wrote in an email to Discovery News.<br><br>Another option is hydrogen gas, but there is not geologic evidence of a fluid rich in hydrogen, he added.<br><br>The researchers also point out that the concentrations of carbon in the lunar melts is basically the same as woolrich outlet online what is found in Earth basalts that erupted from the mid ocean ridges.<br><br>Saal and colleagues previously showed that Earth and the moon have similar concentrations of water and other volatiles, as well as similar ratios of hydrogen isotopes.<br><br>ANALYSIS: Volcanoes Erupted 'Recently' on the Moon<br><br>The studies have implications for ongoing efforts to determine how the moon formed. The leading theory air jordan homme is that Earth was hit by a Mars sized object early in its history and that the moncler doudoune debris eventually melded together to form the moon. How a common pool of volatiles could have survived the impact has yet to be resolved.<br><br>"The volatile evidence suggests that either some of Earth's volatiles survived that impact and were included in the accretion of the woolrich outlet online italia Moon or that volatiles were delivered to both the Earth and Moon at the same time from a common source perhaps a bombardment of primitive meteorites," Saal said in a statement.
