It only happens once every few years: a brackish river in New Jersey freezes over, and the iceboats come out. It's happening all over the Northeast, where an unusually cold winter is welcomed with delight by aficionados of this sport. Lightly constructed, beautiful, and fast (the record stands at 84 miles an hour propelled by wind alone), iceboats provide a winter thrill ride like none other. Iceboating or ice yachting has thrived in pockets of North America and Europe since the nineteenth century. When conditions are right, see them sailing and racing in Wisconsin, on the Hudson, in Maine, Minnesota, Prince Edward Island. and wherever else "hard-water sailors" congregate.

On October 9th, NASA spacecraft will run into the moon, and on purpose. The Lunar Crater Observation and Sensing Satellite (LCROSS) and its rocket's Centaur upper stage will impact the moon, with the goal of sending some of the (possibly present) ice above the lunar surface. Once out of the eternal shade of the moon's south pole, sunlight will break the ice up into H+ and OH- molecules, which can be detected by the Lunar Reconnaissance Orbiter (LRO). The initial impact site was the crater Cabeus A, but the target was later changed to Cabeus (proper), selected for highest hydrogen concentrations with the greatest level of certainty, and for the high-contrast back drop to detect ejecta and vapor measurements. NASA has provided guides for amateur observations of the impact, a facebook group, and a Twitter feed so you don't miss the moment.
'There is no such thing as polywater because if there were, there would also be an animal which didn't need to eat food. It would just drink water and excrete polywater' - Richard Feynman
If you were doing research in the 60s, You might've heard of Polywater, A form of water that exhibited wide variety of interesting characteristics and existed under identical conditions to that of normal water. Eventually debunked, none the less is a fascinating story. Naturally one draws parallels to Vonnegut's ice nine, but did you know there actually is an ice nine? In fact, there's twelve to sixteen types of ice, depending on your opinion. More recently, computer simulations have indicated water may structure itself into icosahedra, which, incredibly, is the platonic solid (described over 2000 years ago!) representing the element water! And if you don't know what an icosahedron is, I bet you've used one before. One of the most ubiquitous, and arguably most important, substances in our lives, our understanding of water is far from complete.
We're making another effort to find water on the moon. Beginning in 1964 with the Ranger spacecraft, we've been lobbing things at poor old Luna. Lately we've been trying to find water there so that future explorers don't have to haul the stuff up the gravity well from Earth. [more inside]
Scientists have discovered a planet composed of scorching hot ice. Originally thought to be a gas giant due to its mass, its actually only four times the size of Earth and most likely composed of exotic forms of ice, such as Ice VII and Ice X with s surface temperature of 300° C.
Next Thursday, NASA will announce the discovery of huge water ice oceans on Mars. Lying less than a metre beneath the surface south of 60° latitude, the water ice reservoirs if melted would form an ocean 500m deep covering the entire planet. NASA insiders believe these findings could result in a manned landing within 20 years.
