Ocean Surface Topography Mission/Jason 2 Begins Mapping Oceans
Less than a month after launch, the NASA-French space agency Ocean Surface Topography Mission (OSTM)/Jason-2 oceanography satellite has produced its first complete maps of global ocean surface topography, surface wave height and wind speed.

Overview of Observations Made During the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) Spacecraft's Flyby of Mercury
Launched in August 2004, MESSENGER is midway through a complex interplanetary cruise phase that involves six planetary flybys.

Exploring Titan's Surface of Ice and Organics
Titan has been long known to be a photochemical factory.

Earthshine: Earth's Spectra, Albedo, Clouds, Climate, and the Search for Earth-Like Exoplanets
Earth-like planets around distant stars may be too far away to be reached by spacecraft but scientists could still investigate whether they harbor life.

Origins of Planetary Systems and the Development of Prebiotic Conditions
Scientists at NASA's JPL brought together to develop new interdisciplinary tools for interpreting observations of protostellar disks returned by space telescopes such as Spitzer and Hubble.

Formation of Nitrogen Atmosphere On Titan
Why does Titan, a moon of Saturn, possess a large nitrogen atmosphere, when the only other planetary body in our Solar System where vast quantities of nitrogen are observed is our own planet Earth?

Near-infrared Spectra of Laboratory Water-Methane (H2O-CH4) Ice Mixtures
Distinguishing methane ice from water ice and their combination using infrared spectroscopy.

Strain at Radially Fractured Centers (RFCs) on Venus
Fractures which extend for very large distances are the result of magma intrusions (dikes) below the surface.

Single-Molecule Resolution of Optical Microscope
Researchers at JPL have developed the first optical nanoscope, the Flourescence Apertureless Near-field Scanning Optical Microscope (FANSOM).

Updates on High-Dispersion Spectroscopy, Radial Velocity and the Planet Search Program
The California-Carnegie team will be able to study the radial velocity of stars with more precision than ever before.

Low Frequency Plasma Oscillations Observed at Mars During 2003 Solar Storms
Because of Mars's lack of an intrinsic global magnetic field, the solar wind interacts directly with the Martian ionosphere.

Cassini Magnetometer Finds an Atmosphere on Saturn's Moon Enceladus
The Cassini spacecraft's two close flybys of Saturn's icy moon Enceladus have revealed that the moon has a significant atmosphere.

Habitability in High Radiation Environments: The Case for Gaia at Europa
Icy satellites with significant heat, irradiation and subsurface water sources may provide common abodes for life.

To Sea or Not to Sea: Titan's Paradigm Malfunction
A single paradigm that had been developed to study the Saturnian system and its largest moon, Titan, has been shaken to its core.

Spectral Mapping of Phoebe Reveals Water and Carbon Dioxide-Rich Composition on Surface
The existence of carbon dioxide strongly suggests that Phoebe did not originate in the asteroid belt.

Migration of Phyllosilicates Through the Solar Nebula Could Explain Water-rich Planetary Formation
Shock waves through icy parts of the solar nebula may be the mechanism that enriched ancient meteorites (called chondrites) with water.

Scientists Have Detected Sunlight's Gentle Nudge on Asteroids
The team's precise ranging revealed that Golevka was 15 kilometers further away than had been predicted by considering gravitational forces alone.

Evidence of Cold-based Glaciers in the Dry Valleys of Antartica Could Help Scientists
Evidence of cold-based glaciers in the dry valleys of antartica could help scientists study the terrain of the Martian landscape.
