Aeolus satellite launch secured
ESA and Arianespace have signed a contract to secure the launch of the Aeolus satellite. With this milestone, a better understanding of Earth’s winds is another step closer.The contract, worth €32.57m, was signed at ESA headquarters in Paris, France, by ESA’s Director of Earth Observation Programmes, Josef Aschbacher, and CEO of Arianespace, Stéphane Israël.
New applications for ultracapacitors offer greater energy density
Devices called ultracapacitors have recently become attractive forms of energy storage: They recharge in seconds, have very long lifespans, work with close to 100% efficiency, and are much lighter and less volatile than batteries. But they suffer from low energy-storage capacity and other drawbacks, meaning they mostly serve as backup power sources for things like electric cars, renewable energy technologies, and consumer devices.
Making nanodiamonds by smashing nanotubes
Superman can famously make a diamond by crushing a chunk of coal in his hand, but Rice University scientists are employing a different tactic.Rice materials scientists are making nanodiamonds and other forms of carbon by smashing nanotubes against a target at high speeds. Nanodiamonds won't make anyone rich, but the process of making them will enrich the knowledge of engineers who design structures that resist damage from high-speed impacts.
Technique takes 3D thermal images of satellites
Scientists from the National Physical Laboratory (NPL) have developed a technique for taking 3D thermal images of satellites. The technique is being developed for prospective use at the European Space Agency's (ESA) largest vacuum facility, the Large Space Simulator (LSS). The measurements will better allow measurement data to be compared with thermal models, verifying their accuracy.
Crystalline fault lines provide pathway for solar cell current
A team of scientists studying solar cells made from cadmium telluride, a promising alternative to silicon, has discovered that microscopic "fault lines" within and between crystals of the material act as conductive pathways that ease the flow of electric current.
NASA launches citizen science opportunity
Now available for Apple and Android phones, the app is an initiative of the Global Learning and Observations to Benefit the Environment (GLOBE) programme, a science and education effort that for over two decades has enabled schools and students in over 110 countries to investigate their local environment and put their observations in a global context hand holding cell phone and clouds.

How to dock CubeSats: Research funded by ESA
The miniature satellites known as CubeSats already play a variety of roles in space. In future they could also serve as the building blocks of other, larger missions by being docked together in orbit.CubeSats are nanosatellites of standardised dimensions based on multiple 10cm sided cubes, which ESA is employing for both educational and technology-demonstration purposes.
Astronomers get millions of hours on supercomputers
Researchers from Astrophysics and Planetary Science at the Niels Bohr Institute have just been granted 91 million CPU hours on European supercomputers for three major research projects.
