Space Station Research Exposing the Salty Truth of Supercritical Water Transitions

Images of water/saline solution being heated.

There is a moment when everything changes. Something familiar crosses a boundary and suddenly behaves in new ways. Take water for example. In middle school science class, you probably learned about saturation points when adding salt to a liquid. Or you discovered the importance of phase changes when ...

Increasing the Speed of Deep Space Communications

Dr. Daniel Raible and Dr. Aaron Swank at work on iROC test bed.

Back in the early history of transatlantic shipping, sea captains used sextants to point to the stars in order to navigate earthly destinations. Today, scientists at NASA’s Glenn Research Center are developing advanced technologies using the same celestial navigation concepts, but this time to find ...

NASA's communications experts have begun flight testing a prototype radio as part of the agency's contributions toward fully integrating civil and commercial Unmanned Aircraft Systems (UAS) into the National Airspace System (NAS). This particular radio is one of the first steps to provide the ...

Frigid Heat: How Ice Can Menace a Hot Engine

The Propulsion Systems Laboratory at NASA Glenn

NASA Glenn scientists are working with manufacturers to figure out how ice can accumulate at high altitudes in hot turbofan engines. Read an excerpt from the article featured on the NASA Glenn website. How does ice accumulate inside hot turbofan jet engines during flight? NASA scientists, working ...

Test Facility Has New One-of-a-Kind Capability, Replicates Ice Crystal Icing Formation

Pre-test inspections of the contraction duct leading to the turbofan engine test article

For the first time ever, researchers are demonstrating ice crystal icing formation in the Propulsion Systems Laboratory (PSL), a full–scale–engine test facility at NASA Glenn. No other engine test facility has this capability. The tests duplicated the natural event of an aircraft’s turbofan ...

PUMA Technology Monitors Pilots and Patients

PUMA Headgear

Technology originally designed by NASA Glenn scientists to monitor the health of astronauts is finding new applications here on Earth that could significantly impact the safety of pilots and the rehabilitation of cardio-pulmonary patients. Read an excerpt from the article featured on the NASA Glenn ...

SLICE and BASS Featured in “Burning Questions on the International Space Station”

Burning Plastic Sphere

Whether suspended in midair or burning their way through a ball of plastic, flames have consumed the attention of combustion researchers in experiments for years, both on Earth and in space. Further refining our understanding of the structure and performance of flames is the focus of two experiments ...

IVGEN Undergoes Lifetime Testing in Preparation For Future Missions

Astronaut TJ Creamer with IVGEN hardware aboard ISS

A Solution for Medical Needs and Cramped Quarters in Space Imagine you're an astronaut exploring the surface of Mars, when suddenly you fall ill or injure yourself. As your team struggles to get you safely back to base, you become seriously dehydrated. With their trusty -- and ingenious -- kit, ...

NASA’s Goddard, Glenn Centers Look to Lift Space Astronomy out of the Fog

A NEXT engine fires at full power in a test chamber.

Utilizing new developments in solar arrays, electric propulsion and lower-cost expendable launch vehicles, NASA's proof-of-concept mission is the Extra-Zodiacal Explorer (EZE), a 1,500-pound EX-class observatory. Its engine, NASA’s Evolutionary Xenon Thruster (NEXT), is an improved type of ion ...
