Dawn holding in second mapping orbit

NASA's Dawn spacecraft is healthy and stable, after experiencing an anomaly in the system that controls its orientation. It is still in its second mapping orbit 2,700 miles (4,400 kilometers) above dwarf planet Ceres.

Engineers create stretchable batteries

Origami, the centuries-old Japanese paper-folding art, has inspired recent designs for flexible energy-storage technology. But energy-storage device architecture based on origami patterns has so far been able to yield batteries ...

Dawn in excellent shape one month after Ceres arrival

Since its capture by the gravity of dwarf planet Ceres on March 6, NASA's Dawn spacecraft has performed flawlessly, continuing to thrust with its ion engine as planned. The thrust, combined with Ceres' gravity, is gradually ...

The revolutionary ion engine that took spacecraft to Ceres

The NASA spacecraft Dawn has spent more than seven years travelling across the Solar System to intercept the asteroid Vesta and the dwarf planet Ceres. Now in orbit around Ceres, the probe has returned the first images and ...

First-ever look inside a working lithium-ion battery (w/ Video)

For the first time, researchers have been able to open a kind of window into the inner workings of a lithium-ion battery. Using a neutron beam, chemists and engineers at The Ohio State University were able to track the flow ...

Engineering researchers develop next-generation battery

(Phys.org) —A research team from the University of Alberta has used carbon nanomaterials to develop next-generation batteries capable of charging faster and lasting longer than today's standard lithium-ion batteries.

Battery design could reduce electric car weight

Battery weight has long vexed engineers designing electric cars for the mass market. Bigger batteries are needed to power a car for longer distances, but their weight in turn requires the car to expend more energy.
