This winter, two sounding rockets will launch through the aurora borealis over Norway to study how particles move in a region near the North Pole where Earth's magnetic field is directly connected to the solar wind.
NASA's Operation IceBridge, an airborne survey of polar ice, recently finalized two overlapping campaigns at both of Earth's poles. Down south, the mission observed a big drop in the height of two glaciers situated in the Antarctic Peninsula, while in the north it collected much needed measurements of the status of land and sea ice at the end of the Arctic summer melt season.
Digital measurements of millions of trees indicate that previous studies likely overestimate the amount of carbon stored by temperate US forests, according to a new NASA study.
Earth's deep interior transport system explains volcanic island lava complexities
A team of scientists from Caltech and JPL suggests that 3.8 billion years ago, Mars might have had only a moderately dense atmosphere. The scientists have identified a photochemical process that could have helped such an early atmosphere evolve into the current thin one without creating the problem of 'missing' carbon and in a way that is consistent with existing carbon isotopic measurements.
During the early morning of Nov. 24, Tropical Storm Sandra became the 18th named storm of the 2015 Eastern Pacific hurricane season. NASA's Global Precipitation Measurement or GPM mission core satellite passed over the new storm and looked at its clouds and rainfall.
A UC Berkeley study of the cohesiveness of Phobos has concluded that Mars' largest moon -- one of only two in our solar system moving inward towards its planet -- will eventually be torn apart by tidal forces and distributed in a ring around the planet. This would take about 10-20 million years, and the ring will persist for up to 100 million years before the dust falls into Mars' atmosphere and burns up as 'moon' showers.
Tropical Cyclone Annabelle ran into adverse atmospheric and oceanic conditions and was fading quickly on Nov. 24. But the day before, NASA's RapidScat instrument saw some dying bursts of wind from the weakening Southern Indian Ocean system.
The Global Precipitation Measurement mission known as GPM passed over Typhoon In-fa and found extreme rainfall occurring in the storm. GPM is a satellite that can estimate rainfall rates from space. It's a jointly managed satellite by both NASA and the Japan Aerospace Exploration Agency.
The intensity of earth's magnetic field has been weakening in the last couple of hundred years, leading some scientists to think that its polarity might be about to flip. But the field's intensity may simply be coming down from an abnormal high rather than approaching a reversal, scientists write in a new paper in the Proceedings of the National Academy of Sciences.
