canopic jug writes:Ken Shirrif writes about restoring the computer which helped guide spacecraft from the Earth to the moon and back again. The Apollo Guidance Computer restoration team, consisting of Mike Stewart, Carl Claunch, Marc Verdiell, and Ken Shirrif ran into challenges simulating the permanent storage. In flight the persitent storage was made of core ropes, though these were simulated on the ground. The team is currently reverse engineering the rope simulators, which were used on the ground and originally built with 7400-series TTL integrated circuits, so as to avoid having to thread an overwhelming multitude of cores with each new version. Once completed the programs were hard-wired into the computers by passing wires through magnetic rings, a process which took many weeks and had to be done correctly the first time. The restoration team opted for a simpler method and built theirs from a BeagleBone.

RandomFactor writes:Rocket scientists at Purdue University in west Lafayette, Indiana have come up with a new approach to plasma thrusters which will potentially increase their reliability and efficiency making them more suitable for softball sized nanosatellites, which are becoming more and more common.Plasma thrusters have traditionally used one of two approaches to fuel. A solid propellant, usually Teflon (polytetrafluoroethylene, that is ablated and vaporized and then passed through a field that accelerates it.
