Control surfaces don’t do anything in a vacuum so there is no ‘steering’. You would therefore be reliant on the direction of thrust from the engines. These are pretty powerful. If that thrust doesn’t go exactly through the centre of gravity (which is changing all the time with fuel burning and astronauts moving about) then the rocket goes spinning off into space like a Catherine wheel. Even with technology today, building a servo that could react quickly enough to a moment like that would be very hard, not least because there is no damping whatever. I wouldn’t have a clue how to even model a system that invites oscillations with an infinite Q. There point is that there is zero chance of a the computers on board Apollo 11 being able to do it.
I am on a new medication(myrbetriq) which was started in August for my over active bladder. I don’t even recognize my face in the mirror anymore. I have developed the moon face and put on considerable weight.
I am now having to look at stopping the medication and going back to enduring the pain and over active bladder / interstitial cystitis. It is a tough decision for me. Without the medication it affected every aspect of my life: I wasn’t able to go out, participate in life/ everyday activities. On the medication I can participate in life but I have to accept the side effects (moon face, weight gain). It is such a tough decision for me because: I don’t like what I see in the mirror, I don’t recognize myself, I am embarrassed. I look like I have put on 50 pounds and I know that is impossible with what I eat. Anyone know of any tricks or other medication that is effective for interstitial cystitis/over active bladder without the side effect of moon face, weight gain.
Spudis, too, sees the bulk of Moon colonization as the purview of future generations. “I’m 62, and I’m near the end of my career,” he says. “I’ve got to leave something.” Doing that can be tough when the space community is a “sort of circular firing squad,” competing for funding and attention. “At some point—and I have to believe this, or I would quit tomorrow—logic will prevail,” he adds. “People will see that what’s holding us back is this model of having to launch everything from the bottom of the deepest gravity well in the solar system. To break that tyranny, that log jam, we’ve got to think differently.”
