L. Marcus Posted November 27, 2014 Report Share Posted November 27, 2014 I use Chrome; it says "External link" just by the cursor, but at the bottom of the screen the whole link address is spelled out. Very handy. But, for my part, I do believe I have made a habit of writing a description of any link I post hereabouts. When I do not do so, just assume my innate scatterbrainedness again came to the forefront. Quote Link to comment Share on other sites More sharing options...

tkdguy Posted December 5, 2014 Author Report Share Posted December 5, 2014 For Europe, yes. I only gave the time for the east and west coasts of the USA. Launch was scrubbed today. They will try again tomorrow. Same Bat-time, same Bat-channel. Quote Link to comment Share on other sites More sharing options...

tkdguy Posted December 9, 2014 Author Report Share Posted December 9, 2014 Lots of links this round, so I'll put them in groups: Asteroids Incoming! What would an asteroid impact look like? Like raindrops on the sand. Spacecraft Out of gas? What's next for Orion? Mars This crater may once have been a lake. I like pie. I never thought I'd say that in this thread! Gas giants & friends See Jupiter and its moons tonight, weather permitting. Rogue winds sculpt dunes on Titan. L. Marcus 1 Quote Link to comment Share on other sites More sharing options...
Cancer Posted December 9, 2014 Report Share Posted December 9, 2014 Asteroids What would an asteroid impact look like? Like raindrops on the sand. I dunno about this. It would be nice if they could have done impacts at an oblique angle; I am all but certain the results would look nothing like real impact craters. It's clear that surface tension is perhaps the dominant force in their videos after the initial strike, while impact cratering is hypersonic so everything happens faster than any internal material forces. Because the incoming bolide penetrates several times its size into the surface before its back side realizes anything has happened; the result is that it vaporizes at depth and excavates the crater with that explosion, which is why approximately all impact craters start off as circular independent of angle of impact with the surface. What happens after the blast depends on the size of the crater, as gravity, rock strength, rarefaction mechanics, etc., don't scale in the same way as that initial excavating explosion. The image below is linked from a NASA site, which has the permission from the textbook, as noted in the image itself. Jhaierr, tkdguy and L.

And for some good news, we may not need to worry about that big asteroid in my previous post, at least not in the short term Link Quote Link to comment Share on other sites More sharing options...
