Here are the top 10 military traditions that need a lot of explaining to your civilian family members.
NASA Tests Model of Powerful New Rocket
Engineers at NASA's Marshall Space Flight Center in Huntsville, Alabama, are wrapping up acoustic testing on a 5-percent scale model of NASA's Space Launch System. The Aug. 28 test, the 34th in the series, will help NASA engineers understand how loud the SLS vehicle will be during liftoff. Data from the test series will be used to design the water sound suppression system that reduces liftoff vibrations on the vehicle. SLS will be the most powerful rocket ever built for deep space missions, including to an asteroid and ultimately to Mars. (NASA/MSFC)
