Titan Calling

27.09.2004


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 Saturn’s 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 moon’s 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 it’s 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 Cassini’s 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 California’s Mojave Desert, and use all his engineering insight and creativity to expose the flaw before time ran out.


IEEE Spectrum and space expert James Oberg take you inside that titanic struggle in the October 2004 issue of Spectrum.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Explanation for puzzling quantum oscillations has been found

So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics

Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...

Next-generation gravitational wave detector in space will complement LIGO on Earth

The historic first detection of gravitational waves from colliding black holes far outside our galaxy opened a new window to understanding the universe. A...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
