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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
