Waspie_Dwarf Posted August 13, 2014 #1 Share Posted August 13, 2014 Tall Boulder Rolls Down Martian Hill, Lands Upright A track about one-third of a mile (500 meters) long on Mars shows where an irregularly shaped boulder careened downhill to its current upright position, seen in a July 3, 2014, image from the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter.Read more... 2 Link to comment Share on other sites More sharing options...

qxcontinuum Posted August 16, 2014 #6 Share Posted August 16, 2014 Wait what? A 3.5 meters boulder must have at least 2 tons on earth. What exactly can move this boulder on Mars . It is irregular shaped oblong as I could see. The lows of physic should say a 2 tons oblong boulder is kinda impossible to start moving by itself downhill.

It is irregular shaped oblong as I could see. The lows of physic should say a 2 tons oblong boulder is kinda impossible to start moving by itself downhill. Are you implying someone pushed it ? First of all it wouldn't weigh 2 tons on mars, it would be about 800 kg. Secondly it looks pretty round to me ! A good guess to what might get it rolling would be a seismic event (mars quake ?). There is also wind on Mars, while I grant that it is very weak, a steady push might have got it moving if it exerted pressure long enough. We can't really see how steep the hill is on this image, maybe someone can shed a little light on that ? If the hill is steep enough the rock doesn't even have to be round to get moving. This is just two ideas I can think of, I am sure that the scientists can come up with more that I have not thought about. Link to comment Share on other sites More sharing options...

toast Posted August 16, 2014 #9 Share Posted August 16, 2014 I would say Mr. Boulder has been sitting at the hill for some billions years and resulted by wind the sand around him has been blown away or/and the surrounding rock has been eroded so that he wasn`t fixed anymore and gravity did the rest. Or so. Link to comment Share on other sites More sharing options...
toast Posted August 16, 2014 #10 Share Posted August 16, 2014 heres the tracks it left And heres what happened in the pics http://www.dailymail...d-rockfall.html Thats one of the reasons why I do not feel well in the mountains. 1 Link to comment Share on other sites More sharing options...
keithisco Posted August 16, 2014 #11 Share Posted August 16, 2014 Judging by it's Delta shape it is obviously a crash - landing of an ET Space Ve' hickle... Link to comment Share on other sites More sharing options...

There are people that will take you seriously. We already have a poster that seems not to have heard of rock slides. As a t-shirt I saw the other day said: Common-sense is now so rare it should be reclassified as a super-power. 1 Link to comment Share on other sites More sharing options...

You need to go to the mountains and see what moves. I like to say that mountains speak. They groan and moan and through up huge amounts of dust. The really big ones are called landslides. PS Everyone has given away the answer as to "What exactly can move this boulder on Mars." Please read the thread and learn the answer. PPS You need to review your laws of physics. Making stuff up about something being impossible is not one of the laws of physics. Link to comment Share on other sites More sharing options...
