I am a big fan of good engineering, and it can be argued that some of the very best engineering goes into the various aspects of the space program. Voyager 1 has now left the solar system. The fact that an object could be swinging around the solar system since nineteen seventy-seven and still operate twenty-eight years later is amazing.
It isn't like it didn't face untold peril at the hands of the universe. Asteroid belts, extreme cold, intense radiation, and metal fatigue have all been features of its trip, and now it is headed out into deep space. Probably the only man made device ever to leave here operational. You can read more at cnet.
I think that it is a testament to the engineers that worked on the program that it is sending back data about the heliosphere, or the point at which the solar winds stop pushing outward, and the space beyond our immediate vicinity. Hopefully we can learn more about conditions in deep space, hopefully enough so that in another 28 years or so, we could have a manned, peaceful, flight out there. If the current administration has its way, however we might find ourselves there sooner, but in a craft bristling with weapons on the way to fight who knows what. Oh well, they say that armed conflict advances the human condition faster than anything else, so perhaps battle in the high frontier will convince us that fighting over resources is ridiculous.
