Space Origami
November 8th 2007 02:20
Viewing conditions have not been the best at in my neck of the woods, I have been busy with some projects lately and have not been able to write my weekly blogs on astronomy and other things, I hope to be able to contribute more writings soon.
If there are people, students, etc who would like a software program to view the planets and stars from the comfort of your own computer. May I suggest a program called Stellarium this program is a planetarium based software that shows exactly what you see when you look up at the stars. It's easy to use, and free I have enclosed a link for download Click here
Origami in space
Sounds a little strange yet somewhat interesting.
A Japanese team in a space experiment that uses reverse origami to show the way to help keep satellites in their respective orbits, or to return spent rocket stages quickly to Earth by means of a tether stretching around a kilometer in length. Tethers have been used in space experiments for some time with mixed results although a number have been successful a few have had malfunctions resulting in jammed equipment and severed tethers.
The Japanese team have employed a novel way in storing and deploying tethers the stored tethers look very much like rolled up fire hoses. This is the reverse origami part The product starts folded, and is then pulled up from the top to produce a nearly straight line. In this fashion, researchers believe, the tether can be deployed 1 km in only a few minutes. The purpose of the tether is to hold objects in space to keep them from drifting apart and to produce electricity see video of NASA lost tether incident below.
