Abstract: A single-event model capable of capturing bias- dependent effects has been developed and integrated into the BSIM4 transistor model and a 90 nm CMOS process design kit. Simulation ...

The moonlit Martian night sky, lit up mostly by Mars' nearer and larger moon Phobos (outside the frame) has a reddish-brown hue due to the dust in the atmosphere, so when green auroral light is added, ...

Thanks to NASA’s Hubble Space Telescope and the Mars Atmosphere and Volatile Evolution (MAVEN) mission, researchers are uncovering new clues. These tools help track how Mars slowly lost its ...

For planets closer to the sun — like Venus, Earth and Mars — more violent space weather events, such as CMEs, can also trigger auroras. Despite having virtually no atmosphere, Mercury has also ...

In orbit, the expanded atmosphere increased drag on thousands of satellites. NASA's ICESat-2 lost altitude and entered safe mode while NASA's Colorado Inner Radiation Belt Experiment (CIRBE ...

This model is available in both 30-mm- and 50-mm ... and wide-field for imaging the night sky. The entire kit weighs just 3.64 pounds (1.65 kilograms), which makes it really portable.

This discovery, published in Science, suggests that Mars' ancient atmosphere was rich in carbon dioxide. Researchers estimate that this atmospheric composition could have allowed liquid water to exist ...

"The main model is a futuristic all-terrain moon rover with rocker suspension, four-wheel steering, deployable solar panels and a rotating arm," reads Lego's product page for the 1,082-piece kit.

The atmosphere’s fast mixing time scales were thought to inhibit ... The resulting hysteresis is shown in observational data and reproduced in a general circulation model where it increases with ...
