StereoPhoto Maker

Stereo Photo Maker 

Many years ago I was hanging out with some friends of mine when one of them produced some colored pencils and a pair of red/green anaglyph glasses. We then spent a fun filled evening trying to draw things in 3D. Had pretty good results. Anyway, I was bitten by the stereo image bug. Soon after that I bought a 1954 Kodak Stereo camera and stocks to make my own slides. Hundreds and hundreds of images later I now want to scan them into the computer and do more with them. For quite a while I was using Photoshop to align the images and tweak them until they looked good but that was taking hours. Then I happened on a bit of freeware called StereoPhoto Maker. It was exactly what I had been looking for. It allows me to make parallel pairs, cross eye pairs, color anaglyphs and other formats that I never thought I’d ever be able to make. The alignment system is simple to use yet powerful enough to fix just about any image you throw at it. I shoot a lot of stereo pairs using the ‘hip switch’ method (stand with your weight on one foot and take the shot, then while still looking through the viewfinder at the subject tranfer your weight to your other foot and take the second shot) because it saves on the cost of getting film processed. In doing this sometimes the images are not exactly on the right axis and need to me tweaked a bit. StereoPhoto Maker steps right up and hits a home run. I have a set of photos on both my TeamDroid gallery and my Flicker gallery that have been made using this program. You can even add a lower third credit to your images if you want. It’s an amazingly handy program, if your shooting 3D images you should take a look at it.

Lost In Space

 

Oh bother, looks like a mistake during a down link hand off from one ground station to another resulted in the robotic lander Minerva to be dropped at the wrong time. Hayabusa (it’s shadow is visible on the above photo, cool eh?) had been making burns to keep station over the asteroid Itokawa when the lander was commanded to release. The spacecraft was moving away at a speed of 15cm/sec, 2cm/sec faster than the asteroids escape velocity. So, Hayabusa launched Minerva into space. That sucks, I was looking forward to seeing that hop around on the surface. However, all is not lost. The laser range finder system on Hayabusa is working great, the thrusters are working pretty well to keep correct orientation, and plans for the slug to be shot into Itokawa is still on the short list of planned events.

Gravitational tractor for towing asteroids

 

 

Dr Edward Lu and Dr Stanley Love propose that a rocket be launched into space, effectively to act as a giant magnet. The gravity tractor would hover alongside the asteroid, with its thrusters pointing outwards so the exhaust does not affect the surface. The tractor would then pull the asteroid off course, merely using the gravitational pull between the two bodies. The scientists calculate that, with sufficient warning, a 20 tonne gravity tractor could safely deflect an asteroid 200 metres across in about a year of towing.
