Scientists have provided the most comprehensive details yet of the journey energy from the sun takes as it hurtles around Earth's magnetosphere. Understanding the changes energy from the sun undergoes as it travels away and out into space is crucial for scientists to achieve their goal of some day predicting the onset of space weather that creates effects such as the shimmering lights of the aurora or interruptions in radio communications at Earth.

Water for Future Mars Astronauts?

Within its first three months on Mars, NASA's Curiosity Rover saw a surprising diversity of soils and sediments along a half-kilometer route that tell a complex story about the gradual desiccation of the Red Planet. Perhaps most notable among findings from the ChemCam team is that all of the dust and fine soil contains small amounts of water.

Since the discovery of the Van Allen radiation belts in 1958, space scientists have believed these belts encircling the Earth consist of two doughnut-shaped rings of highly charged particles -- an inner ring of high-energy electrons and energetic positive ions and an outer ring of high-energy electrons.

This Way to the Space Station

The Orbital Sciences Corporation Antares rocket, with the Cygnus cargo spacecraft aboard, is seen as it launches from Pad-0A of the Mid-Atlantic Regional Spaceport (MARS), Wednesday, Sept. 18, 2013, NASA Wallops Flight Facility, Virginia. Cygnus is on its way to rendezvous with the space station.

When NASA's Terra satellite passed over Tropical Storm Humberto on Sept. 17, the MODIS instrument aboard took a picture of the storm and it resembled the letter "A" as it moves through the northeastern Atlantic Ocean.

The Orbital Sciences Corporation Antares rocket, with the Cygnus cargo spacecraft aboard, is seen as it launches from Pad-0A of the Mid-Atlantic Regional Spaceport (MARS), Wednesday, Sept. 18, 2013, NASA Wallops Flight Facility, Virginia.

NASA commercial space partner Orbital Sciences Corporation launched its Cygnus cargo spacecraft aboard its Antares rocket at 10:58 a.m. EDT Wednesday from the Mid-Atlantic Regional Spaceport at NASA's Wallops Flight Facility in Virginia.

Researchers from the past didn't have the technology to get the pictures Chandra gets.

NASA Images the Floods in Colorado

Intense rainfall in northern and eastern Colorado brought widespread, destructive flooding in mid-September 2013. Local citizens reported as much as 18 inches (46 centimeters) of rain from September 9 to 15, with some of the heaviest accumulation along the front range of the Rocky Mountains.

In Tribute to Washington Navy Yard Victims

A United States flag is flown at half-staff just outside the Mid-Atlantic Regional Spaceport (MARS) Pad-0A with the Orbital Sciences Corporation Antares rocket, Tuesday, Sept. 17, 2013, NASA Wallops Flight Facility, Virginia.

Earth's Calm Skies Over Three Oceans

We live on a dynamic, restless planet. On any given day, there is usually a cyclone, tropical depression, or extra-tropical storm brewing somewhere on the Earth. But for a brief moment this week, the skies over all of the oceans were relatively calm.

NASA's Mars rover Curiosity now has a view of a patch of exposed bedrock scientists selected for a few days of close-up study, the first such study since the rover began its long trek to Mount Sharp two months ago.

The Sun-grazing asteroid, Phaethon, has betrayed its true nature by showing a comet-like tail of dust particles blown backwards by radiation pressure from the Sun. Unlike a comet, however, Phaethon's tail doesn't arise through the vaporization of an icy nucleus.

The MESSENGER project is celebrating the posting today of the 1,000th featured image from Mercury. The Mercury Dual Imaging System (MDIS) team has posted a new image to the MESSENGER website approximately once per business day since March 29, 2011, when the first image obtained from orbit about the innermost planet was made public.

NASA's Lunar Atmosphere and Dust Environment Explorer (LADEE) launched on time Friday night at 11:27 pm EDT aboard a Minotaur V rocket from NASA's Wallops Flight Facility in Virginia. The LADEE mission will orbit the Moon to gather detailed information about the lunar atmosphere, conditions near the surface and environmental influences on lunar dust.

A Solar Eclipse Seen from Mars

Images taken with a telephoto-lens camera on NASA's Mars rover Curiosity catch the larger of Mars' two moons, Phobos, passing directly in front of the sun -- the sharpest images of a solar eclipse ever taken at Mars.

Using an instrument on NASA's Solar Dynamics Observatory, called the Helioseismic and Magnetic Imager, or HMI, scientists have overturned previous notions of how the sun's writhing insides move from equator to pole and back again, a key part of understanding how the dynamo works. Modeling this system also lies at the heart of improving predictions of the intensity of the next solar cycle.

NASA's Mars rover Curiosity has used autonomous navigation for the first time, a capability that lets the rover decide for itself how to drive safely on Mars.

In an attempt to answer prevailing questions about our moon, NASA is making final preparations to launch a probe, the Lunar Atmosphere and Dust Environment Explorer (LADEE), at 11:27 p.m. EDT Friday, Sept. 6, 2013, from NASA's Wallops Flight Facility on Wallops Island, Va.

More Evidence of Water on the Moon

NASA-funded lunar research has yielded evidence of water locked in mineral grains on the surface of the moon from an unknown source deep beneath the surface.
