07.16.15 – STEREO-A Spacecraft Returns Data From the Far Side of the Sun
This image of the sun was taken on July 15, 2015, with the Extreme Ultraviolet Imager onboard NASA's Solar TErrestrial RElations Observatory Ahead (STEREO-A) spacecraft, which collects images in several wavelengths of light that are invisible to the human eye.

07.16.15 – NASA Cites the Return of the STEREO-A Spacecraft
On July 11, 2015 we received our first images in over three months from NASA's Solar TErrestrial RElations Observatory Ahead spacecraft, or STEREO-A. Since March 24, 2015, STEREO-A has been on the far side of the sun, where it has had to operate in safe mode, collecting and saving data from its radio instrument.

07.09.15 – Scientists Study Atmosphere of Venus through Transit Images
Two of NASA's heliophysics missions can now claim planetary science on their list of scientific findings. A group of scientists used the Venus transit - a very rare event where a planet passes between Earth and the sun, appearing to us as a dark dot steadily making its way across the sun's bright face - to make measurements of how the Venusian atmosphere absorbs different kinds of light.

05.12.15 – DHS/NASA Space Weather Twitter Chat
When solar storms release solar flares and coronal mass ejections, or CMEs, toward Earth, we can feel the effects here on the ground.

04.28.15 – The Fearsome Foursome: Technologies Enable Ambitious MMS Mission
It was unprecedented developing a mission that could fly four identically equipped spacecraft in a tight formation and take measurements 100 times faster than any previous space mission – an achievement enabled in part by four NASA-developed technologies that in some cases took nearly 10 years to mature.

04.22.15 – NASA Goddard Team Sets High Flying Record with Use of GPS
After years of hard work building a spacecraft, a mission team anxiously awaits after a launch – will the instruments they've crafted all work as well as planned?

04.09.15 – NASA Study Finds Small Solar Eruptions Can Have Profound Effects On Unprotected Planets
While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable – a balance between a sun that provides energy and a planet that can protect itself from the harshest solar emissions.

04.08.15 – Seasonal, Year-Long Cycles Seen on the Sun
Our sun is constantly changing. It goes through cycles of activity – swinging between times of relative calm and times when frequent explosions on its surface can fling light, particles and energy out into space.

03.24.15 – NASA Funded Mission Studies the Sun in Soft X-Rays
At any given moment, our sun emits a range of light waves far more expansive than what our eyes alone can see: from visible light to extreme ultraviolet to soft and hard X-rays.

03.12.15 – Launch Begins MMS Mission in Spectacular Fashion
The four spacecraft of NASA's MMS spacecraft are flying high above Earth to begin a comprehensive experiment designed to uncover the details of magnetic reconnection and the energy it produces.

03.11.15 – Superfast Sensors for New MMS Mission
Scheduled to launch on March 12, 2015, the MMS mission carries sensors with unprecedented observational speeds, including, the Fast Plasma Investigation, or FPI, which was built at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

03.10.15 – NASA to Investigate Magnetic Explosions
Magnetic reconnection could be the Universe's favorite way to make things explode. The problem is, researchers can't explain it.
