Characterizing the Moon's radiation environment

The radiation environment near the Moon could be damaging to humans and electronics on future missions. To characterize this potentially hazardous environment, the Cosmic Ray Telescope for the Effects of Radiation (CRaTER) ...

Solar variability and terrestrial climate

(Phys.org)—In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of ...

Study: Autumn sets in rapidly on Saturn's moon Titan

Thanks to NASA's Cassini spacecraft which has been orbiting Saturn since 2004, scientists have been able to observe for the first time ever the seasonal atmospheric circulation direction change on Titan – an event which ...

Night-time view of Aurora

(Phys.org)—Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun ...

Voyager observes magnetic field fluctuations in heliosheath

As they near the outer reaches of the solar system, for the past several years the two Voyager spacecraft have been sending back observations that challenge scientists' views of the physics at the edge of the heliosphere, ...

Suomi NPP satellite sees auroras over North America

(Phys.org)—Overnight on October 4-5, 2012, a mass of energetic particles from the atmosphere of the Sun were flung out into space, a phenomenon known as a coronal mass ejection. Three days later, the storm from the Sun ...

Sputtering: How mars may have lost its atmosphere

Why is Mars cold and dry? While some recent studies hint that early Mars may have never been wet or warm, many scientists think that long ago, Mars once had a denser atmosphere that supported liquid water on the surface. ...

NASA Radiation Belt Storm Probes to launch, UNH components aboard

At 4:08 a.m. Thursday, August 23, NASA's twin Radiation Belt Storm Probes are scheduled to launch from Cape Canaveral, Florida on a two-year mission to investigate Earth's hazardous radiation belt environment as never before. ...
