Before he died, the man who knew more about the Van Allen radiation belts (and cosmic radiation in General) questioned the validity of manned space flights…

Simple: The taxpayers should not spend one dime on this.

Bezos, Musk, etal can spend as much of their own money and that of willing volunteers as they want with no government restriction.

A leading space scientist has called to question the validity of human spaceflight, suggesting that sending astronauts outward from Earth is outdated, too costly, and the science returned is trivial.
So let's just sit right here that is guaranteed to be near an imploding star.

DID YOU EVEN READ THE ARTICLE THAT YOU POSTED????

No.

You clearly did not.

James Van Allen said nothing about the "validity" of manned spaceflight.

James Van Allen expressed doubts about the continued UTILITY of manned spaceflight.

Furthermore, he was talking about the Space Shuttle and the ISS, neither of which is anywhere near a Van Allen radiation belt.

You are not engaged in honest discussion.

Interplanetary radiation makes roundtrip spaceflight to mars difficult (heavy) as plain old water is the shielding of choice. A Case for Mars said 5000KG of water to protect against interstellar radiation and the nuclear submarine reactor that you need to make return fuel and energy from the surface of mars.

Space X challenge is to re integrate light weight 500KW-1MW nuclear power back into the surface mission on mars. Solar power is fine for a 4 astronauts kept warm by a toaster oven on mars, but very quickly a mars base is going to want to make ceramic materials to build things to build into the surface to get away from lack of radiation protection provided by the very tiny mars atmosphere.

Hunter Biden was engaged in corrupt influence peddling with Russian, Ukrainian, and Communist Chinese government interests, to benefit himself and his perverted pedophile father.

Joe Biden used his former Vice Presidential office to cover up his son’s corrupt financial dealings with foreign interests.

Joe Biden illegally kept classified documents, in an insecure garage at his home, from both his time as a senator and his time as Vice President.

It’s not just about science. It’s about EXPANSION.

No, he questioned if manned flights should continue due to the human lives lost in that last shuttle disaster.

It seems to me you’re disingenuously insinuating that he is questioning whether or not we actually sent astronauts through the radiation zones named after him.

What is the source of your motivation to attempt to discredit the Apollo moon landings?

Conspiracy theorists lack critical thinking skills

"The more people believe in conspiracy theories, the worse they perform on critical thinking tests, a new study has confirmed..."

"...Critical thinking is the objective analysis and evaluation of a situation – and requires a number of cognitive skills.

These include the ability to think systematically, see other perspectives, change your mind when new evidence arises, identify relevant versus irrelevant information, identify and discard logical fallacies, be aware of biases and avoid them, and look beyond the obvious.

None of this is particularly easy.

What the researchers found was a strong association between lower critical thinking skills and an increased tendency toward believing conspiracy theories.


The Cure for Belief in Conspiracy Theories
How intellectual humility is an antidote to belief in false conspiracies.

Intellectually humble people have an appropriate level of awareness of their intellectual weaknesses.

People who hold the above beliefs fail to appreciate their intellectual limits appropriately and accurately assess what those limits are.

Intellectual humility is a crucial virtue for avoiding irrational belief in conspiracy theories...

...Many who believe and then propagate false conspiracy theories are also failing to own their intellectual weaknesses....

The Russians were in on the hoax because in 1968 they claimed they sent a rocket to the moon with two tortoises on it (Zond 5), in part to pretend they were testing the effects of the Van Allen belts. The hoax also claimed both tortoises returned to earth quite alive, apart from being a bit peckish because they hadn't been fed in almost a week.

I haven't yet worked out a plausible reason why the Russians would have aided the US's hoax space program, but I found some magic mushrooms in the garden today, and I have high hopes they'll do the trick.


The US also hoaxed the launch of their own rocket in 1968 (OV1-13) with a fake radiation instrumentation package. After a 13-month hoax mission to measure and map the Van Allen belts, they hoaxed having the certain knowledge how to pass an astronaut through the belt unharmed.

Right now the prospect of moving man faster than the speed of light to new worlds is just a mathematical equasion called the Alcubierre Warp Drive. The math would allow you to go to Alpha Centauri in two weeks as measured by clocks here on Earth.

And before we landed on the moon some people thought that the lander would sink into into the moon since it just had to be covered with a layer of dust.

Didn't happen.

So what is your obsession with the moon landing?
