- Testing Composite Cryotank Technology For Future Deep Space Missions
NASA has completed a complex series of tests on one of the largest composite cryogenic fuel tanks ever manufactured, bringing the aerospace industry much closer to designing, building, and flying lightweight, composite tanks on rockets. At NASA's Marshall Space Flight Center in Huntsville, Alabama, the tank was lowered into a structural test stand where it was tested with cryogenic hydrogen and structural loads to simulate stresses the tank would experience during launch. The project is part of NASA's Space Technology Mission Directorate, which is innovating, developing, testing and flying hardware for use in NASA's future missions. Cryogenic propellants are gasses chilled to subfreezing temperatures and condensed to form highly combustible liquids, providing high-energy propulsion solutions critical to future, long-term human exploration missions beyond low-Earth orbit. In the past, propellant tanks have been fabricated out of metals. Switching from metallic to composite construction holds the potential to dramatically increase the performance capabilities of future space systems through a dramatic reduction in weight. > NASA Completes Successful Battery of Tests on Composite Cryotank Image Credit: NASA/David Olive

30 years ago today, we woke up to the fact that over 200 of my fellow Marines were killed by a truck bomb. A truck bomb…now we have the “fancy” term Vehicle Borne Improvised Explosive Device (VBIED). In accordance with … Continue reading

On this day 237 years ago our Corps became a reality. The first Marines were recruited, and signed their papers on this day in 1775. In a small tavern in Philadelphia the United States Marine Corps was born. Today we celebrate that … Continue reading
Beirut . It was the bloodiest day in the Corps’ history since World War II, when Marines fought to secure Iwo Jima. On October 23 1983, around 6:20 am, a yellow Mercedes-Benz truck drove to Beirut International Airport, where the … Continue reading
Rarely do I delve into the “meme” of “Someone You Should Know”. However, recent events have drawn me to three individuals that need to be singled out for doing their jobs, and paying the ultimate price for doing them well. … Continue reading
A look inside the Martial Arts Center of Excellence in Quantico. I may have posted this previously but, I like it. Part 1: Part 2: Part 3:
As noted I spent the last 3 days in the DC area. Yes there was storm damage. Yes we had to scramble on arrangements for our meetings, lodging, etc. Not a big deal. I travel a lot. One thing that … Continue reading
