This technology was first used during the Arctic expedition of Ann Bancroft and Liv Arnesen, who were forced to cancel their voyage seven days in due to a combination of damaged gear, frostbite and extreme cold. Although they were unable to access the images because extremely low temperatures prevented them from switching on their computer, people at their base camp viewed the images and passed on the sea ice conditions to them by phone.
International Polar Year (IPY) is an internationally coordinated two-year effort in which more than 5000 scientists from 60 countries will conduct research in the Arctic and Antarctic to increase our knowledge of the polar regions, how they are changing and how those changes impact the health of our planet.
This IPY not only marks the first time satellites will be used to help guide expeditions but also the first time scientists will be armed with satellite measurements to better understand these regions, which play a vital role in the Earth's climate and ecosystems.
ESA will make significant contributions to IPY on a variety of scientific fronts. In addition to providing Earth observation data free of charge to 48 projects, the agency will co-lead a large IPY project – the Global Interagency IPY Polar Snapshot Year (GIIPSY) – with the Byrd Polar Research Centre. The goal of GIIPSY is to make the most efficient use of Earth-observing satellites to capture essential snapshots that will serve as benchmarks for gauging past and future changes in the environment of the polar regions.
This service was developed and is being operated by Kongsberg Satellite Services (KSAT), equally owned by the Norwegian Space Centre and Kongsberg Defence and Aerospace.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
Broadband rotational spectroscopy unravels structural reshaping of isolated molecules in the gas phase to accommodate water

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
