Between the walls, fabric with the same functionality as in bulletproof vests is deployed. This design enables the shield to defeat debris objects up to 1 cm in size. The same double-wall design is used by military forces to protect heavy armoured vehicles, such as tanks, and in this usage...
"These new results by the Cluster mission clearly show that multi-point observations are the key to understanding the magnetic substorm phenomenon," says Philippe Escoubet, Cluster and Double Star Project Scientist of the European Space Agency. Note to editors The findings appear ...
after 7.4% growth in 2014. Nonetheless, the number of Internet users in developing countries has almost doubled in the past five years (2010-2015), with two thirds of all people online now living in the developing world.
Revenue for downloaded audio nearly doubled between 2012 and 2016, from 299 million to 643 million dollars. In 2013, revenue from online retail exceeded that of brick-and-mortar bookshops for the first time. In 2016, about 814 million units were sold into online channels. About 672 million ...
Now by combining observations by Herschel of the OH 119 um doublet line and by Suzaku in X-rays in the same galaxy, IRAS F11119+3257, it has been shown that the small-scale fast SMBH accretion winds can drive the large scale molecular outflows in this z=0.189 ULIRG. This result has...
fast-moving small shards of debris able to damage or destroy a functioning satellite. For example, in 2007, the intentional destruction of the FengYun-1C satellite doubled the amount of debris at an altitude of about 800 km, leading to a 30% increase in the total population of debris at ...
Venus Express is designed to carry out scientific observations over two Venusian days, corresponding to 486 Earth days. The mission could be extended to double the nominal duration. Notwithstanding the intense previous exploration (Venus is the third most visited celestial body in our solar syste...
As in LISA, the proof masses fulfil a double role: they serve as mirrors for the interferometer and as inertial references for the drag-free control system. The LTP also contains the mechanisms to hold and release the test masses, to discharge any charge build up on the test masses or ...
It is extremely easy to burn, if oxygen is present. Used in Europe’s Ariane 5 launchers, hydrogen is an excellent rocket fuel, but it is very hard to store. It must be kept in double-walled tanks at very low temperatures, then fed to the rocket engines through tightly sealed pipes....
During this period, the instrument teams calibrate the data taken by Solar Orbiter from its ever-changing distance to the Sun. That would be a fast turn-around at the best of times; with the unprecedented challenges of the pandemic this year, it is a double achievement to hit the dead...
