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.

Today, plants and microorganisms are heavily used for the production of medicinal products. The production of biopharmaceuticals in plants, also referred to as “Molecular Pharming”, represents a continuously growing field of plant biotechnology. Preferred host organisms include yeast and crop plants, such as maize and potato – plants with high demands. With the help of a special algal strain, the research team of Prof. Ralph Bock at the Max Planck Institute of Molecular Plant Physiology in Potsdam strives to develop a more efficient and resource-saving system for the production of medicines and vaccines. They tested its practicality by synthesizing a component of a potential AIDS vaccine.
The use of plants and microorganisms to produce pharmaceuticals is nothing new. In 1982, bacteria were genetically modified to produce human insulin, a drug...
Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.
The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
