NASA tests new spacecraft propellant gauge on lunar lander

It's easy to measure fuel in tanks on Earth, where gravity pulls the liquid to the bottom. But in space, the game changes. Quantifying fuel that's floating around inside a spacecraft's tank isn't so simple.

Brr, it's cold in here! NASA's cryo efforts beyond the atmosphere

Establishing sustained operations at the moon and Mars presents a multitude of opportunities and challenges NASA has yet to encounter. Many of these activities require new technologies and processes to ensure the agency is ...

Surface of Saturnian moon Enceladus shields buried organics

The Saturnian moon Enceladus presents a unique opportunity in our solar system to search for evidence of life, given its habitable ocean and plume that deposits organic-bearing ocean material onto the surface.

JWST looks at the debris disk around a white dwarf

Debris disks are quite common in the universe. Young stars have protoplanetary disks from which planets form. Black holes have accretion disks that are the source of the galactic jets. Supernova remnants can form a disk around ...

Inclined drops: New model allows description of slipping drops

The behavior of drops on surfaces is of interest for a variety of applications. However, properties such as velocity, friction or shape on inclined surfaces depend on a large number of parameters—their behavior is still ...
