The 1996–1999 models in Mexico are rebadged Dodge Caravans, although the Caravan was sold alongside the Voyager. For 2000, the Chrysler Voyager was identical to the Plymouth Voyager except that the 3. 8 L V6 was not available. Base models of the Voyager were offered in most states with either a 2. 4 L four-cylinder or a 3. 0 L Mitsubishi V6 engine, except in California and several northeastern states, where the Mitsubishi V6 didn’t meet emissions standards. In those locales, the 3. 3 L engine was offered instead.
For the European market, Voyagers continued to be rebadged Caravans. Unique to this market were 2. 0 L Straight-4 SOHC and DOHC engines and 2. 5 L turbo diesel produced by VM Motori. European market vans also came with manual transmissions and in a six-passenger model with six captains chairs, not available elsewhere.
With the GRAIL data, the astronomers were able to map the gravity field both in and around over 1,200 craters on the lunar far side. This region--the lunar highlands--is our Moon's most heavily cratered, and therefore oldest, terrain. Heavily cratered surfaces are older than smoother surfaces that are bereft of craters. This is because smooth surfaces indicate that more recent resurfacing has occurred, erasing the older scars of impact craters.
But small moons like Methone are usually geologically inactive and bereft of an atmosphere. Therefore, they are usually unable to smooth away the scars. Dr. Peter Thomas of Cornell University in Ithaca, New York, explained it this way in the May 17, 2013 New Scientist: "When we look at objects less than 200 kilometers in radius, they are all like potatoes. They have lumps, grooves, craters." This makes Methone's smooth surface a mystery. Dr. Thomas is a Cassini team member.
We live in a Cosmic "shooting gallery". Objects inhabiting our Solar System have been profusely and mercilessly blasted by showering asteroids and comets for billions and billions of years. However, planets and large moons have their way of smoothing away the scars--their strong gravity pulls them into a nice ball-like spherical shape. Furthermore, some of these larger spheres possess sufficient internal heat to cause flows of fiery lava and other volcanic features that can fill in the scars of impact craters. A few such large bodies are blasted by strong winds and pouring rains, which also erode away the pockmarks left on their surfaces by showering impactors.
