Ganymede may be "club sandwich" moon

In a combination of the astronomical and the culinary, scientists at NASA’s Jet Propulsion Laboratory (JPL) say that Jupiter’s largest moon, Ganymede, may not have a single large ocean, but instead may be built like a club sandwich with alternating layers of ice and water. The claim is based on computer models of how salt water acts under the high pressures that may exist beneath Ganymede’s global ice pack, and may improve the chances of finding life elsewhere in the Solar System.

Is Ceres an oasis between Mars and Jupiter?

In mid-2015, the asteroid probe Dawn is scheduled to establish orbit around Ceres, the only dwarf planet in the inner Solar System, as well as the largest asteroid, to begin roughly six months of close-up observation. The level of interest in this mission has significantly increased with the detection by the ESA's Herschel space observatory of plumes of water vapor being exuded from Ceres' surface from a pair of local sources.

McLaren's ultrasonic force field to replace windshield wipers

Windshield wipers are life-savers, but also can drive one to distraction with their incessant streaking and chattering. Well, the tyranny of the wipers may soon be over. McLaren Automotive’s chief designer Frank Stephenson told The Sunday Times that the performance motoring company is investigating the use of "ultrasonic force fields" to replace windshield wipers in automobiles. While Stephenson referred to a military source for McLaren's tech, there appears to be very little public information on how such force fields might clean a windshield during a storm, so I'm taking a look at the patent history to see how this might be accomplished.

Spin Chill turns beverages cold in 60 seconds

Since the earliest days of brewing beer and making wine, the search has been on for an easy, affordable method of chilling drinks quickly without diluting them in the process. Florida-based start-up Spin Chill claims to have a solution to this vexing problem with a portable device that (literally) turns beverages ice cold in 60 seconds. Read More

Radical new icebreaker will travel through the ice sideways

Given that icebreakers clear a path for other ships by traveling through the ice head-on (or sometimes butt-on), then in order for one of them to clear a wider path, it would have to be wider and thus larger overall ... right? Well, Finland’s Arctech Helsinki Shipyard is taking a different, more efficient approach. It’s in the process of building an asymmetric-hulled icebreaker that can increase its frontal area, by making its way through the ice at an angle of up to 30 degrees. Read More

ON-WINGS takes ice detection to the next level

On most aircraft ice-detection systems, the sensors can’t be located right on the aerofoil surfaces that most need to be kept ice-free – the addition of a protruding sensor would ruin their aerodynamics. Now, however, UK-based GKN Aerospace has announced the new ON-WINGS system. It mounts completely flush with the skin of the aircraft, allowing it to be integrated directly onto wings, rotor blades, or anyplace else that needs to be kept sleek and free of ice. Read More
