OSIRIS-REx Will Help Us Learn How to Mine Asteroids
Topic: Meteorites, Comets and Asteroids
08/14/13
Summary: Asteroids could one day be a source of valuable resources for Earth, and for missions beyond our planet. An upcoming NASA mission could provide a valuable step toward accessing these numerous small bodies in our solar system.

Measuring Meteor Dust
Topic: Meteorites, Comets and Asteroids
08/13/13
Summary: Some 10 to 40 tons of meteoric dust enters Earth's atmosphere every day. Studying this material could teach astrobiologists about the early Solar System and provide clues about the origin of life on Earth.

Stars Don't Obliterate Their Planets Very Often
Topic: Cosmic Evolution
08/12/13
Summary: A new study using data from NASA's Kepler Space Telescope shows that hot Jupiters are not regularly consumed by their host stars.

Swinging Between Ice Ages
Topic: Earth
08/11/13
Summary: Using computer simulations, scientists have demonstrated that the ice-age/warm-period cycle on Earth depends heavily on the alternating influence of continental ice sheets and climate.

Moon Radiation Findings May Reduce Health Risks to Astronauts
Topic: Moon to Mars
08/11/13
Summary: Data from NASA's Lunar Reconnaissance Orbiter (LRO) shows that lighter materials like plastics will provide effective shielding against radiation for astronauts during extended space travel.

Carbon Under Pressure Exhibits New Traits
Topic: Earth
08/10/13
Summary: A new technique is allowing scientists study samples that are heated and squeezed within an electron microscope. Researchers have used the method to reveal new clues about how and where carbon is located within Earth's interior.

Genetics of 'Sand' May Shed Light on Evolution
Topic: Origin & Evolution of Life
08/10/13
Summary: Scientists are using tiny fossil shells from microscopic organisms called planktonic foraminifera to understand more about the process of evolution.

The Sun's Magnetic Field is About to Flip
Topic: Sun
08/09/13
Summary: Measurements indicate that the Sun's vast magnetic field is about to flip, and the event will have effects throughout the Solar System.

Is Europa Habitable?
Topic: Europa
08/09/13
Summary: A new study outlines potential science goals for a robotic mission to the surface of Europa. A Europa lander could study the composition and geology of the moon's icy shell and the potential for life in its subsurface ocean.

Ice May Explain Mars's Double-Layer Craters
Topic: Mars
08/08/13
Summary: Geologists have proposed a new explanation for double-layered ejecta craters on Mars.
