Tank purchased over the internet

The internet was created to quickly exchange information between several computers at the most important institutions. Later on it spread towards the general public, taking over the roles of newspapers, radio broadcasts, television shows, even shops! These days you can buy products even from countries that are far away and get them shipped over to you. It's almost as if nothing can surprise you, eh? Well, what happened recently just stunned me.

Someone purchased a working T-55 soviet tank on the internet. The seller is a Latvian, and the tank was even registered as a tractor vehicle, had it's own number plates. Does that mean you can drive around in the city in it? If this didn't surprise you, let me rephrase it: a 39-ton metal soviet warbeast was on sale next to iPods and all other small things you can imagine, on an auction website similar to ebay. Oh, and... did i mention it's a TANK. God, would i love to have one. Hey, i wonder, if i would buy a tank on ebay.com, how much would shipping to Europe cost?

So, what's next? Nuclear warheads on ebay? Time will tell...

Avalanche on planet Mars

Mars's Relief Changes

A NASA spaceship took a unique photo of an avalanche in action (or after the action, i didn't really get that) on February 19th, 2008. The photo, was taken by the High Resolution Imaging Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter.

Scientists noticed the avalanche purely by chance, while checking for seasonal changes on Mars. The area in which the avalanches took place is 3.7 miles wide, 37 miles long and near the north pole. The slope from which the red dust came rumbling down is around 2300 feet high. Natural changes on Mars are rarely recorded, and some known places are said to have been unchanged for millions of years. Scientists are trying to figure out whether something unusual caused this or the avalanches are a part of spring changes.

Personally i think something of a much bigger scale is working somewhere in the background. I understand that this is the first RECORDED avalanche on Mars, but what could have caused such drastic changes in a place that has been calm for millions of years? Maybe Mars's poles are also shifting like Earth's, causing magnetic field changes and moving the little rock and iron particles? Well, I'm not a scientist, so i'll just wait for what they have to say.
