To extinguish a hot flame, DARPA studied cold plasma

DARPA theorized that by using physics techniques rather than combustion chemistry, it might be possible to manipulate and extinguish flames. To achieve this, new research was required to understand and quantify the interaction ...

The methane habitable zone

In the search for life elsewhere, many studies focus on finding liquid water. But what if life could exist with some other solvent? Saturn’s smoggy moon Titan makes scientists question the possibilities for methane-based ...

A water ocean on Titan?

Oddities in the rotation of Saturn's largest moon Titan might add to growing evidence that it harbors an underground ocean, researchers suggest.

NASA Glenn tests alternative green rocket engine

An extensive series of tests has been completed on a new rocket engine that will use a non-toxic propellant combination at NASA's Glenn Research Center. The reaction control engine that was tested provides 100 pounds of thrust ...

Scientists measure changing lake depths on Titan

On Earth, lake levels rise and fall with the seasons and with longer-term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence ...

What is Consuming Hydrogen and Acetylene on Titan?

(PhysOrg.com) -- Two new papers based on data from NASA's Cassini spacecraft scrutinize the complex chemical activity on the surface of Saturn's moon Titan. While non-biological chemistry offers one possible explanation, ...

Rock and Roll: Titan's Gem Tumbler

(PhysOrg.com) -- It appears flash flooding has paved streambeds in the Xanadu region of Saturn's moon Titan with thousands of sparkling crystal balls of ice, according to scientists with NASA's Cassini spacecraft. By analyzing ...
