During my first visit to Chile in 2002, I spent only a couple of days in Santiago.
During my second visit to Chile in 2013, I drove around the northern parts of Chile for 10 days.
Traffic conditions are generally light, except for Santiago. The major problem was road construction. North-east of Antofagasta, the road was under construction for almost 200 km (120 miles). In several places, there was only one lane available, traffic was alternated between the two directions, which once meant a wait of almost ½ hour, before I could pass the 7 km (4.3 miles) one-lane stretch.
The worst single traffic problem was just north of La Serena on the main highway. An accident had completely blocked the road. I waited for 5 hours. The line of waiting cars was probably 20 km (12 miles) long. After 5 hours waiting, I decided to take a detour around the area on a road through the mountains. It was marked on the map as an unpaved road, but it turned out to be hardly more than a track. This was quite an adventure, since I had a regular passenger car, no 4WD.
One of the big impressions in Chile are the mining operations. Mines are everywhere, they are a big part of the economy. Even when talking with local people over a beer, the subject of mines came up. The Mina Escondida is the largest copper mine in the world. It is taking down whole mountains.
The other significant industry in Chile are the astronomical observatories. Because of ideal atmospheric conditions in the high Andes, but still close proximity to transportation infrastructure, there are many observatories in Chile. I drove by several of them to take a picture, and visited the one at La Silla.

On the Road
Road conditions around Santiago are very good. Further away there was a lot of construction, with frequent long delays around parts of the road that were only passable in one direction at a time. In the northern part there were quite a few unpaved roads, but they were mostly in very good shape, no need for 4WD.
Road in the Altiplano desert. (730k) Coastal fog somewhere south of Copiapó. When I got into the fog bank, the visibility dropped to almost zero. I could only drive 20 km/h (12 mph). (442k) Sandstorm near Antofagasta. (484k) Visibility was greatly reduced in the sandstorm. (443k) The fence catches the garbage that is blown around by the storms. (597k) Road work in San Pedro de Atacama. All the roads were dirt roads in the town. They just broke up the old surface, and then planed it again with a roller. It didn't take long to fix the road. (1040k) Trucks on a dirt road heading for each other. (844k) There is frequently fog in this area. If you can see two chevrons, maximum speed is 60 km/h, if you can see only one chevron, the speed limit is 40 km/h (25 mph). The next picture shows what is meant. (583k) These are the chevrons on the road to determine how fast you can go. If the visibility is so low that you can see only one chevron, your speed limit is 40 km/h (25 mph). (633k) Next gas station is 440 km (273 miles) away. That is quite a distance between gas stations, especially since the sign was already about 20 km (12 miles) from the previous gas station. (617k) Dirt road to Laguna Santa Rosa in the Parque Nacional Nevado Tres Cruces. (810k) This is the line of cars and trucks in which I got stuck. The road ahead was closed, I waited 5 hours before I turned around and took a wild detour on a track through the mountains. (1082k)
Mining is the most important industry in Chile. Some of the mines are enormous. The Mina Escondida in the Atacama desert is currently the highest producing copper mine in the world. Recently, the Lithium mines have become very important, since Lithium is now used extensively in batteries. There are several huge Lithium mining operations in the Atacama desert, south of San Pedro de Atacama.
Lithium mining operation in the Salar de Atacama. (1025k) Lithium mine tailings. (862k) Dumping lithium mine tailings. (898k) Mina Escondida, one of the largest copper mines in the world. They are removing a whole mountain. (805k) Front loader in the Mina Escondida. Compare it to the size of the trucks, it is huge. (705k) Truck for hauling mining material. It is as big as a two-story house. (783k) The tires of a mining truck. (829k) Transporting the loading bucket of a mining truck. The trucks on which they are loaded are themselves big, but they are dwarfed by the bucket of the mining truck. (533k) These 4x4 pickup trucks are everywhere. They are used in all the mining operations by the thousands. (988k)
Some of the best astronomical observatories in the world are in the Chilean Andes. The atmospheric conditions there are ideal because of the high altitude and extremely dry air. The logistical conditions are also very good because of close proximity of major roads to any part of the Chilean Andes.
I visited La Silla Observatory on a tour provided by the European Southern Observatory (ESO). I saw the ESO 3.6 m Telescope and the ESO New Technology Telescope (NTT), also with a 3.6 m mirror.
ESO 3.6 m Telescope
The only instrument currently in use on the ESO 3.6 m Telescope is HARPS, the High Accuracy Radial velocity Planet Searcher. It is dedicated to the discovery of extra-solar planets. It is a fiber-fed high resolution echelle spectrograph. The light from the Cassegrain focus of the telescope is sent to the instrument through optical fibers. The instrument itself is housed in a specially air conditioned room that keeps the instrument as stable as possible to be able to detect minute changes in the stars radial velocity. Nobody is allowed to enter the room in which the HARPS instrument is located, to prevent any disturbances of the instrument. The keys to the room are only available to management personnel from ESO on special permission from ESO Headquarters.
ESO New Technology Telescope (NTT)
On the ESO NTT, there are currently two major instruments, SofI and EFOSC2. They are installed on the two sides of the Nasmyth focus.
SofI ("Son of ISAAC") is a near infrared camera and low-resolution spectrograph, with polarimetric and high-time resolution modes, at the Nasmyth A focus. Its largest field of view is 4.92 arcmin, and it covers the 0.9-2.5 micron wavelength range with spectral resolution from 600 to 2200.
EFOSC2, or the ESO Faint Object Spectrograph and Camera (v.2) a visible light camera and low-resolution spectrograph, with multi-object spectroscopy, polarimetry and coronography modes, at the Nasmyth B focus. The instrument has multi mode capability including normal/polarimetric imaging/spectroscopy (several submodes in each), multi-object spectroscopy and coronography.
