Comment Re:NASA and secrets (Score 1) 140

The same people and companies were involved, but there was separation as I understood it between the black side stuff and the civilian stuff. My father made a comment to the effect of, the classified stuff is better than the civilian stuff, gyroscope wise. Star trackers and such are probably not much different.

Comment Another reason automatics are popular (Score 1) 612

Is with the towing trailer set. Or the pickup truck set. Try backing up a grade with a loaded pickup or with a trailer with a stick vs an automatic. The torque converter is a beautiful piece of engineering.

With a stick, you'll burn the clutch trying to creep with it. With an auto, you get inching capability.

In my automobile, I prefer a stick for reliability and control. I think autos have become more reliable than sticks today however.

Comment NASA and secrets (Score 2) 140

My father worked at NASA for 30 years. He was involved in guidance and navigation. Worked on the IU on the Saturn V.

In the '90s, he told me the only thing classified at NASA was the vehicle destruct system details. Don't want someone intentionally blowing up a manned rocket on its proper course. He said that they were denied access to classified gyroscope materials from the spy satellite and ICBM world. Other secrets may have fallen under "trade secret" status as NASA contracted the building of most things.

However, just the other day I downloaded information about the F-1 rocket engine. At one time the documents I downloaded were classified. I guess they didn't want the Soviets to learn more about our tech.

Then the DART mission occurred. Within the report, there was information that might make it easier for bad actors (terrorists/states) to use GPS navigation for munitions. That information is restricted as is some more recent information.

True, the constitution doesn't define what "law" is, but the Supreme court is the ultimate arbiter of the law of the US. And while "war" might be a mitigating factor, secret tribunals are not permitted.

Comment Hydrazine icing? (Score 1) 170

Point taken, I was thinking the same thing. However, it is possible for hydrazine to "freeze" at aerospace temperatures, correct? We justified a shoot down USA-193 on the basis of its massive load of hydrazine, I recall some mention of some of it possibly being frozen.

They are nasty chemicals, just keeping that system under control is difficult.
