From their 1979 approval to their 1984 launch, the Chrysler S-chassis minivans would undergo several major redesigns. Originally intended to use 4 sedan-style doors (similar to a station wagon), Chrysler changed to two sliding doors, claiming better parking-lot access. The design was later changed to a single sliding door, as Chrysler wanted to market the van to commercial buyers; while engineers wanted to make the left-side door an option, the tooling complexity was claimed to be too expensive. During development, the configuration of the rear door was also contentious, with a liftgate winning out over a station wagon-style tailgate. On the exterior, in 1981, the side windows were redesigned to become flush with the body; while requiring a major redesign of components and tooling, the design change allowed for a reduction of wind noise and drag. To further reduce costs, a number of visible interior components were shared with the Dodge Aries/Plymouth Reliant, including the instrument panel, interior controls, radio, and various trim items.
The "Dagwood Sandwich" Moon. Earlier models of Ganymede's oceans were based on the assumption that the existence of salt didn't change the nature of liquid very much with pressure. However, Dr. Vance and his colleagues found, through laboratory experiments, that salt does increase the density of liquids under the extreme conditions hidden deep within Ganymede and similar icy moons with subsurface bodies of water. Imagine adding table salt to a glass of water. Instead of increasing in volume, the liquid will actually shrink and become denser. The reason for this is that salt ions lure water molecules. A Distant, Dusty Moon. Titan experiences changing seasons--just like Earth. In particular, Titan's seasons change around the equinox, when our Sun passes Titan's equator. At this time, huge clouds can form in tropical areas, resulting in violent methane storms. Cassini observed these ferocious methane storms during several of its flybys over Titan. Moon Boots are a winter essential. What exactly are they? Moon Boots are a water resistant or water proof form of footwear that are made from lightweight materials with a specialised thermal lining that can keep the feet and calf warm in temperatures reaching -35oC. The heel and sole of the boot enhance comfort and stability while the sole adds extra warmth due to its own insulating property. These features make them ideal in snow and cold weather conditions. Their appearance reflects an oversize, fancy and snug gumboot.
