Since it started orbiting Saturn last June, the Cassini mission has returned incredible images of the gas giant, its dazzling rings and its enigmatic moons. But its most dramatic chapter will come this January, when a European lander probe (Huygens) that has been piggybacking on Cassini for the last seven years is sent on a fiery plunge into the murky atmosphere of Saturns largest and most mysterious moon, Titan--a chapter that would have ended in disaster, save for an engineer called Boris Smeds.
Titan is completely covered by a thick orange smog of hydrocarbons, and scientists have speculated that oily oceans of methane and ethane may roil beneath the cloaking clouds. After slamming into the moons atmosphere at 21,000 km/hour, Huygens will take two-and-a-half hours to descend through the atmosphere, slowed by parachutes. On its way down its expected to transmit a scientific bonanza from its cameras and instruments, a bonanza that will be picked up by special radio receivers onboard Cassini and then relayed back to Earth.
But unbeknownst to anyone, a lurking flaw in Cassinis receivers meant that the data received by Cassini were going to be hopelessly scrambled. Along with his allies, ESA engineer Boris Smeds developed and championed a rigorous test that revealed the flaw and its cause in time for corrective action to be taken. Doing this required Smeds to battle bureaucracy, travel from his desk in Darmstadt, Germany, to an antenna farm deep in Californias Mojave Desert, and use all his engineering insight and creativity to expose the flaw before time ran out.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
