APSU history honor students present at national conference in New Orleans

 

Austin Peay State University - APSUClarksville, TN – Anyone passing through the Intercontinental Hotel in New Orleans last month might have paused at all the strange questions drifting out of the hotel’s meeting rooms.

“Are werewolves from Europe or Ancient Arabia?” “How did American soldiers fare during World War I?” “Why did Nashville legalize prostitution in the late 19th century?”

Austin Peay State University students give presentations at Biennial Phi Alpha Theta National History Conference.

A Look Back at NASA’s efforts to send Astronauts into Deep Space from 2017

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Below are the top images from 2017 that tell the story of building and testing the systems that will send astronauts to deep space destinations including the Moon, Mars and beyond.

Construction Completed for Stand to Test SLS’s Largest Fuel Tank

Major construction is complete on NASA’s structural test stand that will ensure SLS’s liquid hydrogen tank can withstand the extreme forces of launch and ascent. Together, the SLS liquid hydrogen and liquid oxygen tanks will feed 733,000 gallons (nearly 3 million liters) of super-cooled propellant to four RS-25 engines, producing a total of 2 million pounds of thrust at the base of the core stage.

The 215-foot-tall structural test stand for NASA's Space Launch System is seen Sunday, Sept. 24, 2017, at NASA's Marshall Space Flight Center in Huntsville, Alabama. (NASA/Bill Ingalls)

NASA study shows Loss of Water in Sierras caused Mountain Range to grow taller

 

Written by Carol Rasmussen
NASA’s Earth Science News Team

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Loss of water from the rocks of California’s Sierra Nevada caused the mountain range to rise nearly an inch (24 millimeters) in height during the drought years from October 2011 to October 2015, a new NASA study finds.

In the two following years of more abundant snow and rainfall, the mountains have regained about half as much water in the rock as they had lost in the preceding drought and have fallen about half an inch (12 millimeters) in height.

“This suggests that the solid Earth has a greater capacity to store water than previously thought,” said research scientist Donald Argus of NASA’s Jet Propulsion Laboratory in Pasadena, California, who led the study.

The Sierra Nevada range rose almost an inch during California's recent drought due to loss of water from within fractured rocks. (trailkrum, CC-BY-2.0)

NASA Engineers successfully use 3-D Printed Part on RS-25 Rocket Engine

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Engineers successfully hot-fire tested an RS-25 rocket engine with a large 3-D printed part for the first time on December 13th, marking a key step toward reducing costs for future engines that power NASA’s new heavy-lift rocket, the Space Launch System.

During flight, a rocket may experience powerful up-and-down vibrations mainly due to the engines and propellant in the feed lines. This is called the pogo effect and is similar to the up-and-down motion of bouncing on a pogo stick. The 3-D printed part tested, called the pogo accumulator, is a beachball-sized piece of hardware that acts as a shock absorber by regulating liquid oxygen movement in the engine to prevent the vibrations that can destabilize a rocket’s flight.

The successful hot-fire test of an RS-25 development engine at NASA's Stennis Space Center on Dec. 13 included NASA's largest 3-D printed rocket engine component to date, the pogo accumulator assembly. The test was the first of 50 for NASA's restart of RS-25 engine production. (NASA/Stennis)

NASA Completes Review of First SLS, Orion Deep Space Exploration Mission

 

NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA is providing an update on the first integrated launch of the Space Launch System (SLS) rocket and Orion spacecraft after completing a comprehensive review of the launch schedule.
 
This uncrewed mission, known as Exploration Mission-1 (EM-1) is a critical flight test for the agency’s human deep space exploration goals. EM-1 lays the foundation for the first crewed flight of SLS and Orion, as well as a regular cadence of missions thereafter near the Moon and beyond.

NASA plans December 2019 launch date for the Space Launch System (SLS) rocket and the Orion spacecraft. (NASA)
