No longer will Australian farmers waste their time working land that has no future. Satellite technology has improved to the point where moisture level of farmland can be determined. Waiting for rain that will make no difference is info that farmers can now 'bank' on. Measuring moisture level is now something done by computer, from aerial surveys. The labor-intensive, time-consuming chore is a thing of the past. Soil that has potential rejuvenation can be targetted. The cost is out of the reach of individual farmers at present but the price is falling. It is possible, if use of the new technology becomes widespread, that the output of certain crops can be estimated. Potential shortages will be foreseen and action taken in future plantings. When weather predictions are included the position of markets months ahead will be known. ✴ Technology by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://advent...

It is said there is nothing like blowing your own trumpet. Well, in some cases it can be very pleasing. The fact that the Voyager 1 probe has pass into space beyond the solar system is good news, The US must take most of the praise, but a small country in terms of population played a major part. Australian scientists are base at Canberra's Deep Space Communication Complex (CDSCC). The controlling body is the Commonwealth Scientific and Industrial Research Organisation (CSIRO). This company is a big mover in world science. Many new ideas, concepts and discoveries have their origin at CSIRO. The world's most advanced antennas are situated at the CSIRO base and they have been following Voyager since its launch in 1977. A round trip for a signal forward and back between the Earth and satellite is 34 hours. There are two probes, Voyager 1 and 2. Only one is in deep space. Due to improvements in technology the antennas have been constantly upgraded as the probe journeyed...

It has been found that asteroids can have magnetic fields. This was quite a surprise. Planets have magnetic fields due to a moving molten metal core. Mercury has a very strong field. The reason for this is not yet known. Vesta is a large asteroid with a diameter of 525 kilometer. It was first identified in 1807 by Heinrich Wilheim Olbers. It is the most easily seen asteroid from Earth. Smaller asteroids hit Vesta and some of the debris falls to Earth. The fallen "rocks" can be linked to Vesta because they have the same spectral color match. Vesta is unusual for an asteroid as it once had a crust, mantle and molten metal core. The orbiting dawn spacecraft/satellite confirms this. It is now frozen and no longer active. A meteor named Alan Hills A81001 composed of Vestan crust fell to Earth in the Arctic. When it was analysed it was found to have a weak magnetic field.  The original crust gained  a magnetic field when it cooled 3.7 billion years ago. An impact a...

Bare circles of earth ringed with tall grass are found all over Africa. They have been a mystery with all kinds of stories told about them. Now a partial explanation has been found. Walter Tschinkel has been studying the phenomenon since 2005. At first he thought they were caused by termites which poisoned and killed off the grass. He realized his mistake when he analyzed satellite images - the circles were alive! The circles would disappear then appear somewhere else. However, for the most part circles remain in one place for up to 75 years. The average life was 41 years. Rain tends to be the main factor leading to formation of a new circle. Tschinkel has not discovered the real cause. If fertile earth is put inside a circle grass still will not grow. Something is going on in a chemical or "living" sense. Locals do not want the mystery solved. They make a living out of them. For a fee tourists "adopt" a circle, then keep up-to-date by viewing it on Go...
