The solar array that will provide power to NOAA's GOES-R satellite has been tested, approved and shipped to a facility where it will be incorporated on the spacecraft. The five sections of the solar array come together as one to resemble a giant black wing.
On May 13, 2014, the GOES-R satellite solar array panels were successful deployed in a Lockheed Martin clean room in Sunnyvale, California. The completed solar array was then delivered to Lockheed Martin’s facility near Denver.

"The GOES-R solar array generates more than 4,000 watts of power, twice as much as that of the previous generation of GOES satellites, in order to operate the larger and more capable instruments carried by GOES-R," said Pam Sullivan, GOES-R flight project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
The GOES-R spacecraft uses a photovoltaic solar array to derive electricity from sunlight. Photovoltaics is a method that uses semiconductors to convert solar radiation into direct current electricity.
The solar array is comprised of five separate solar panels that are folded up at launch. After the satellite is released by the launch vehicle, the solar panels are deployed into a single solar array wing that rotates once per day on orbit to continuously point the solar array photovoltaic cells towards the sun.
The solar array provides a stable platform that tracks the seasonal and daily movement of the sun relative to the spacecraft. It will power all of the instruments, including the computers, data processors, attitude control sensors and actuators, and telecommunications equipment.
The instruments include the Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS), the Magnetometer, the Space Environment In-Situ Suite (SEISS), Solar Ultraviolet Imager (SUVI), the Advanced Baseline Imager (ABI), Geostationary Lightning Mapper (GLM), and Unique Payload Services (UPS).
The UPS suite consists of transponder payloads providing communications relay services in addition to the primary GOES mission data. The UPS suite consists of the Data Collection System (DCS), the High Rate information Transmission / Emergency Managers Weather Information Network (HRIT/EMWIN), GOES-R Rebroadcast (GRB), and the Search and Rescue Satellite Aided Tracking (SARSAT) System.
The GOES-R, or Geostationary Operational Environmental Satellite – R Series, advanced spacecraft and instrument technology will result in more timely and accurate weather forecasts. It will improve support for the detection and observations of meteorological phenomena and directly enhance public safety, protection of property, and ultimately, economic health and development.
GOES-R will be more advanced than NOAA's current GOES fleet. The satellites are expected to more than double the clarity of today's GOES imagery and provide more atmospheric observations than current capabilities with more frequent images.
NOAA, the National Oceanic and Atmospheric Administration, manages the GOES-R Series Program through an integrated NOAA-NASA program office, staffed with personnel from NOAA and NASA, and co-located at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.
Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...
