shake rattle and roll
Major redesign required here.
The way I read this is that they are in the process of design and there is no need to redesign something that has not yet had a final design to redesign......or whatever...
Is it the UN space treaty that holds us back?
Modulating flux capacitor......?
I’m not sure if they were testing some J-2 variant at Stennis this past week, but it was definitely making my house shake. A little unusual in that you typically hear the engine testing, but you don’t feel it.
If anyone can figure this out it is NASA.
I hope the last few decades of budget cuts and inattention from the public have not reduced the brain power of one of our most capable agencies.
i’m no space geek but if they could send one up no worries in the 60s why not now?
Now is the time to find these problems.
In the engineering stage.
“Modulating flux capacitor......?”
Simple! Reverse the polarity.
A crack in the dilithium crystals?
“im no space geek but if they could send one up no worries in the 60s why not now?”
I’ll answer that question by saying “Good enough for government work.” In other words, completely unacceptable by non-government standards. NASA has become a monstrous, inefficient beaurocracy. Things crash, break, fall apart, fail to operate, because these morons can’t even read the designs. When something’s supposed to have an auto-guidance using the metric system, and your department programs it to use feet, and no one notices... That’s a SERIOUS PROBLEM!
There are firms that would LOVE to get a contract to build a shuttle, or a space station, or get a man on the moon again. Why won’t we let them try?
I a so old that I know they used to something called a Slide Ruler and then actually build the thing.
And it worked!
Put men on the moon six times and can’t make a vehicle to get us there again? Lends credence to the original hoax.
Of course the simulator had been under development for many years prior to the shuttle's first launch. During that development it was noticed that the "motion base" simulator would experience significant vibrations during the roll maneuver that was part of lift off.
It was presumed that the source of the vibration was an elusive software bug. After many months of fruitless debugging NASA finally took the (rare) step of putting a cash bounty out on the squashing of this particular bug.
Nevertheless, no bug was ever found and launch day approached. When the launch finally did take place, and the roll maneuver was executed for the first time, the astronauts were astonished to experience the very same vibration.
For us nerds that was a pretty neat story.
LESSON LEARNED: Pay attention to your simulatons.
