Google Maps has a Street View option showing zoomable 360° VR views of streets in the United States. Much of the technology used for creating these Street Views could be applied to searching for extraterrestrial objects fallen from the sky onto Antarctica. There are locations in Antarctica where these objects are concentrated, and a person searching on foot can find about one per day. It is very expensive getting people to these locations, and maintaining them there, but by using a balloon lofted camera taking photos from an altitude of about 30 meters most of the fatigue, and expense of hours of fruitless searching between finds could be avoided. When an object is found a helicopter could fly directly to the object, using GPS coordinates, and pick it up. With the low altitude aerial photograph technique the photos could be sharp enough to find even small objects. The photos could be put on the Internet, and volunteers from the public could scan the photos for possible objects of interest. It would be a real Easter Egg hunt with a truly valuable scientific payoff. People are already scanning Google Street Views for interesting things. The search could be made into an Internet game, and have prizes for finding extraterrestrial things. See iRobot and Mars rovers in the Antarctic for more on how to build the low altitude cameras dragged by a balloons.
NASA is considering sending people to Mars to bring back a few pounds of Mars rocks. But why should the American public go to that Trillion dollar expense to get some Mars rocks when many extraterrestrial rocks are already here on Earth? A few rocks believed to have been blasted off of Mars have already been found, but it is difficult to be confident of research based on a few examples. Using this balloon lofted aerial photography technique, thousands might be found which are already here on Earth. Probably there exist places where the extraterrestrial objects are already being deposited by the flowing of the glaciers to places where they melt. Another place of concentration would be where large objects, which would tend to settle downward to the bottom of the Antarctic ice sheets, would be dragged along the bottom as the glaciers moved. When they came to a depression in the stony terrain they would be scraped off of the bottom, and be concentrated into these low spots. There probably exist places where there are thousands of extraterrestrial objects from all over the galaxy, not just Mars, which are concentrated in this way, and may be easily recovered. These places would have much greater diversity of material than any Mars mission to a single place could possibly find. Most of these type of concentrations, from the last few million years, are deep beneath the ice but some of them will have been deposited where the glaciers have routinely melted or perhaps where they came down a steep incline, and broke up leaving their heavier rocks on the rocky surface. Or possibly found on locations where many millions of years ago these same glacial processes deposited them, but which are now located in more temperate locations because of continental drift. The surface of the ancient landscape east of Hudson’s Bay has been scraped clean by repeated glacial flows over the last 4 billion years, but if there existed cracks in this terrain a couple of meters deep and 1 meter to 10 meters wide it would tend to collect meteorites in the cracks. These cracks occur in the terrain as the earth’s core heaves up and down, and the cracks would be at different locations, and in different angles during all those years. Thus if this theory is valid each crack would be filled, and closed tight by geological shifting, and form a time capsule of what fell during some particular relatively short period of time, say a million years.
In the Google Earth photos there is an intersection of cracks in 4 billion year old terrain which has without doubt endured lots of geological events, including a nearby major extraterrestrial impact at 56.2128 -74.5099 . At the dead center of the image above is a small brownish spot inside of the crack slanted at about 100°. It might be a good location for a search. Also on that same crack off to the left there seems to be an area even higher above the current water level and it might be even better. Note that there are other cracks running at about 80° through this same area. The cracks had to form at different times, and therefore if they concentrated materials it would be from those different time periods. Using a metal detector would make sense scanning these cracks because where an iron meteorite is found there is probably a concentrating process which brought it there and so there will be others nearby.
This is only an example of an easily observable terrain. There will be millions of places here on earth which at one time or another were concentration points for these types of objects. We only need to find one of them to create a scientific bonanza.
