true. How many know that Congress killed nuclear propulsion in spacecraft in 1986? JPL had to abandon several types of fission-based engines in various states of completion, some producing velocities capable of reaching mars in 4 days or less. That certainly was more advanced than anything in use now by NASA..Literacy is kind of weird. In the 1990s, there were many “redefinitions” designed to give a false idea of something. Body composition was abandoned in favor of BMI, and so now everyone is “fat” or “obese”. Literacy was changed from being able to read (which most Americans can do) to “functional literacy” which added in a bunch of garbage to make Americans seem less literate than other nations. Homelessness was redefined to include those who have homes, but don’t own them, themselves. Education standards were changed to make American kids seem better educated than they are, but at the same time, it became in vogue to compare the brightest of other nations with the average in this nation for propaganda’s sake. And so on..Hunger is a LOT worse than 5 years ago. More than 20% of American grain, more than 15% of our exports, or some 30+ million tons of grain is now being wasted to produce ethanol (USDA), which in turn reduces engine efficiency from 30% t o 40%, meaning a lot more gasoline per mile is burned. Much of the grain that used to feed Mexico, China, etc., is now being burned up in cars. The price of grain went up, making it very hard on the poor in U.S. and elsewhere. .The most polluted nations on the planet are China and India. China two years ago asked how our environment had been cleaned up. Instead of offering conservationists, who did wonders, they offered radical environmentalists, those people who are gleefully burning up the forests and the TSE species in them and polluting the streams with drug wastes. (I used to work in conserving TSE speces and quickly learned to dislike econuts because of the destruction they caused.) And so an opportunity to clean up the Chinese environment was lost.
