Imagine a technology that would allow space travelers to transmit gigabytes of data per second over interplanetary distances or to navigate to Mars and beyond using powerful beams of light emanating from rotating neutron stars. The concept isn't farfetched. In fact, Goddard astrophysicists Keith Gendreau and Zaven Arzoumanian plan to fly a multi-purpose instrument on the International Space Station to demonstrate the viability of two groundbreaking navigation and communication technologies

Magnetometer
MAVEN’s dual magnetometers will allow scientists to study the interaction between the solar wind and the Martian atmosphere, giving us a better understanding of how Mars has evolved from a warm, wet climate to the cold, arid one we see today.

Raining Loops on the Sun
On July 19, 2012, an eruption occurred on the sun that produced a moderately powerful solar flare and a dazzling magnetic display known as coronal rain. Hot plasma in the corona cooled and condensed along strong magnetic fields in the region. Magnetic fields, are invisible, but the charged plasma is forced to move along the lines, showing up brightly in the extreme ultraviolet wavelength of 304 Angstroms, and outlining the fields as it slowly falls back to the solar surface.

Spinning Mercury Map From Orbiter Snaps | Video
Thousands images from NASA MESSENGER's wide angle camera comprise this rotating false-color mosaic map. The visible colors are correlated with variations in Mercury's surface spectral reflectance.

Outbound Near-Earth Asteroid, as Seen from Spain
This set of images from the La Sagra Sky Survey, operated by the Astronomical Observatory of Mallorca in Spain, shows the passage of asteroid 2012 DA14 shortly after its closest – and safe -- approach to Earth. The images were taken around 12:59 p.m. PST (3:59 p.m. EST, or 20:59 UTC) on Feb. 15, 2013.
The images have been sped up 10 times.
In the last set of images, the fainter object that passes near the top of the field of view is a satellite or another asteroid.

Asteroid 2012 DA14 – Earth Flyby Reality Check
On Feb. 15th an asteroid about half the size of a football field will fly past Earth closer than many man-made satellites. Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet.

Exploding Stars Blow Super-Bubble Of X-Rays | Video
160,000 light years from Earth, the region of hurried massive star growth and supernovas called DL50 is radiating x-rays 20x faster than a typical such structure. Chandra X-Ray Observatory scientists are looking to find out why.
