Recent findings suggest that even Brown Dwarfs may have the capacity to develop planets? (http://www.spaceflightnow.com/news/n0511/29tiniest/) Directly viewing another star or brown dwarf's planets will have to wait a decade or so... when the 'Planetary Finder' mission is launched. Proxima Centuri i...

I like Dr. Oliver K. Manuel's theory that our star, Mr. Sol, is actually a novae remnant! His proof, if correct, is found in meteoric isotope ratios. He champions the idea that Sol actually has an IRON core! The Hydrogen we see on the surface is a byproduct of degenerative neucleosysnthesis. Also, t...

Here's an interesting addy: http://www.spaceflightnow.com/news/n0512/03blackhole/ This article chats up findings from the Spitzer Space Telescope concerning black holes. It appears that matter and energy are streaming OUT of the vicinity of a galactic sized black hole. Accretion disk jets escaping f...

In an electro dynamic universe.. supernovae are an expression of interdimensional structures colliding - string generated vortices. As the energy within those vortices generate gravity and slow below light speed, that energy is transformed into radiation and matter. The massive stars seen exploding ...

The dynamics of impact(s) on thin crust 'water-ice' moons is an interesting subject indeed! Extreme low temperatures transform water ice into a 'rocklike' density... further complicating matters? What would the antipolar nodes of a multi-impact event look like? Harmonic resonances anyone? Gravitatio...

IPOD image 11.14.05.. 'Everest on Mars'
WOW! An earlier post by me mentioned the subject: 'Erosion on Mars at every scale': This 'macro' 360° image from the top of the 'Husband Hills', from the MER rover 'Spirit', shows EXACTLY what I mean... Note that all surface features, close by or far away appear rounded and weathered. NOTE the appea...

My thought was to spray the outside with water vapour, then cover it to protect it from Sol rads. Trick'd be to use a 'Bassard-like' collectors to gather useful matter, i.e. Hydrogen and Oxygen, on-orbit. (nuclear pwr'd Bussards?) Make rad. sheilding as you go along?

It would be difficult, at best, getting the intelligence agencies to release enough technical info. to see whether or not anything could be salvaged and recycled from any of their decommisioned platforms?

Supercell Dust Devils in planetary dust storm conditions, may have 'swept up' the Martian surface.. revealing darker underlying materials? Subsequent storms r...

The problem with modeling 'weather' on Mars is that there is a tendancy to 'compare' it to the water cycle weather patterns, here on Earth. Again, Mars gravity is 38% that of Earth. Extreme temperature gradients exist between the surface and immediately above the surface. Mars seems covered with fin...

Today's closeup image of sand grains in the Columbia Hills
As proposed in an earlier comment, we see erosion at every scale on Mars Golf balls with indentations fly much better and further than without. Less rounded sand granules may be differentiated in a similar fashion? The 'flight characteristics' of sand and dust particles may be enhanced by their shap...

Erosion features on Mars dominate at every scale.
Therefore, the erosional agents themselves are at every scale? Most features 'close up' seem to indicate recent and ongoing 'weathering'. The Rover Spirit has found eroded/rounded rock on the tops of the Columbia Hills. The Rover Opportunity found, and continues to find, billions of Hemotite 'Bluebe...
