Large Atmospheric Count: Large Flat Atmospheric Count: Small Ion Count: Small Hydrogen Count: Small Atmospheric Count: Small Flat Atmospheric Count: Ascent angle: 90° 45° *This is used when you want to use bottom and rear thrusters together. The calculator will reduce thrust to 70.7%. ...
The fact that this system uses a gridded ion thruster, rather than a Hall effect thruster (HET), is interesting, since HETs are the area that Soviet, then Russian, engineers and scientists have excelled at. The higher isp makes sense for a long-term tug, but with a system that seems ...
Another space challenge is multipaction, which occurs when there is an air gap of more than 0.003 inches between mating interfaces. The European Space Agency offers a multipaction calculator, and Amphenol SV also offers insights on whether designs are well within safe operating parameters or if they...
Selene was the very first of her line, created in the brains of a few engineers who had sat down at a table and asked themselves: “How do we build a vehicle that will skim over a sea of dust?” Some of them, harking back to Ole Man River, had wanted to make her a stern-...

Materials, “plumbing”, and “surprises” seem to me likemore ominous problems.They lurk in the complexities between systems, in the gaps between disciplines, and in the interpersonal relationships of the builders and engineers. You don’t learn about them until you’ve built your entire rocket...

engineers, and other people in all walks of life have had to deal with an unreasonably high benchmark for human achievement, frequently having listen to others complain, “How come we can put a human being on the moon, but we can’t have a VCR or microwave clock that won’t lose the...
So, code has different effects on conduct from the given of the green, amber, red of traffic lights to the fact that only 23 people can be present in an AOL chat-room at once (originally a choice of code engineers), to the amount of information able to be collected on each person ...
