    Michael Crichton had this bit in (I think) Terminal Man where a company was being paid to develop an automated ping pong playing robot. It was called HAPP (Hopelessly Articulated Ping Pong player). The speculation was that the researchers were being paid to develop a short range ballistic defence system without actually knowing the real objective.

    Building a humanoid skiing robot may deliver insights into how humans keep their balance. Maybe there is a new angle on hydroplane surface vessels with active suspension here.

    I can only begin to imagine the complications of wind farms interfering with military radars which scan much closer to the Earth's surface

    Turbines are a problem when they reflect signals back to the radar with sufficient Doppler shift to get past filters for static reflections. The emission from this device won't be near the frequency of the military radars (you would think) so there is unlikely to be a problem.

    Particles of dust can survive reentry because their mass is low compared with their surface area. There is a lot of meteoric dust in the upper atmosphere for this reason and it has been suggested that there would be less precipitation on Earth without meteoric dust to nucleate rain drops.

    That usb key is more massive than most of the bright meteors you might see in the night sky. It won't survive atmospheric entry, though building a heat shield around it probably wouldn't be difficult.

    Just to be pedantic, it was actually the Commander (Armstrong) who actually flew the LM to the surface, not the misnomered LMP, who mainly monitored things and called out warnings and readings. So if anyone said P66 (which the transcript doesn't indicate literally happened), it was more likely the Commander, who would've entered the program. The transcript has Armstrong saying "I'm going to..." when he goes into P66.

    You might hear P66 twice. Once when the commander asks for it, then a second time when the LMP enters the verb and echoes the new mode verbally to the CDR. Often though the LMP got to be able to read the CDRs mind about this. The last couple of minutes of the landing were heavily drilled.

    It doesn't surprise me that its not in the apollo 11 transcript. I was talking generally about all the flights. The breakdown in the division of responsibility between Armstrong and Aldrin has been discussed many times. The CDR had his attention in the cockpit because of the executive overflow problems (1202) in the PNGS. Consequently he let the LM get too low before he designated a good landing site and wasted fuel finding a smooth spot.

    But as the other poster said. The commander flys the vehicle and the LM pilot drives the computer. Communication between them is verbal which is why you hear the modes being called out.

    The Apollo 17 ALSJ is a good read. You can hear how the crew were continually hazing their rookie scientist Harrison Schmitt. At one point during the landing he calls out to Cernan that the descent rate is ...um.... a little bit too fast.

    Sorry, what do you mean about the 6 being beside PRO? In terms of UI design, that is.

    Because it is an easy finger movement. A bit like how "nb" or "hg" are easy to type on a qwerty keyboard. P66 was something of a turning point for the crew. I believe it had special significance for them.

    This is an Apollo DSKY BTW. A Classic command would have been

    [VERB]66[PRO]

    Which loosely translated means give me manual control, I need to land this sucker. If you watch the descent movies you will hear "P66" being called out by the LMP a few minutes before landing. Interesting to note that the 6 is right beside PRO. I wonder if there is a bit of clever UI design in that.

    It was amazing they did so well on Apollo. The only real guidance screw up was on Apollo 11. Every other landing was spot on. Apollo 12 had been targeted for the middle of surveyor crater and was dead on when Pete Conrad got his first look at the landing sight. He had to fly manually to avoid the target.

    ...was the first flight to land in terrain where the descent trajectory had to be designed to avoid high altitude terrain. By that I mean they had to fly over a mountain, then into a valley for the landing.

    The terrain model in the PNGS had five vectors in memory to represent terrain. Back in those days, RAM was expensive.

    To clarify: the ATC simulations are run very professionally. My point was that the success of a simulation generally depends on how seriously it is taken by the managers and participants. At one extreme this medical thing could be like the joke online training courses I sometimes have to do.

  25. Re:Shockingly sensible on Med Students Get Training In Second Life Hospitals · · Score: 1

    I work in air traffic control and simulation is also an important function of our systems. It works well because the simulator is just the operational system running in a different mode. From the POV of the operator they interact with the system the same way. The most important factor is that the people who run the simulation take it very seriously.

    Once when I was at the pool with my family a woman approached us and said she was going to simulate drowning, and asked us not to get involved. The first aid people were running a sim and I suppose it worked okay but for me it was a bit like the evacuation sims we do at work. In a real fire I would be the first out of the building running right over the bodies of my valued co-workers.

    I have a suspicion that second life simulation may turn into a "tick the box" test. Just get it done. You know the rules and they don't really relate to reality.
