Two planets in our universe are inhabited. One is the Earth, where people have made a mess of things for centuries. The other is Mars, which is totally inhabited by robots, driving, drilling, listening, sampling their way around that sandy wasteland.
For reasons to escape some flat-earthers, a lot of curiosity exists about Red Planet only half the size of the Earth. The destruction of Mars, they believe, can give light to the origins of life on Earth. Of course, the deterioration of Arizona's destruction is cheaper.
But there are new implications that people – at least the kind of Americans – enter into one of their irregular cycles of uneasy curiosity about space and the deadly mysteries that hide there. We were back in the 1960's, which President Kennedy took to be the first country to get people to the Moon.
Today, a new Gallup poll has found out that for the first time most Americans favor the sending of a man or woman mission there to explore Mars. Today, it's 53 percent for it and 46 percent.
That's really a change in just 20 years when most Americans say, Forget about it.
Back in 1969 on the days of glory of the US space program after the first two astronauts only walked the Moon and successfully returned, only 39 percent told Gallup that they favor sending astronauts to Mars while 53 percent opposed to the idea.
And this is an interesting twist: Going to Mars is a two-party deal, with both Republican and Democratic positives on the idea (55 percent) and 53 percent of the independents are in favor. Support for such a mission is greatest among teens and at least seniors, although they are coming around.
The focus of the past decades is sending non-army army robots to pass or to orbit different planets or months and in some fascinating cases are visiting Mars to drive around and discover that place.
The study of effects on human bodies of long-standing weights near the Earth orbit involved in the International Space Station, flying around the Earth 16 times a day at 17,500 miles at a time and 270 miles high.
Of course, astronauts in the US, Russia and Europe spend only a few months there. That is roughly equivalent to a one-way journey on Mars, which varies from 34 million to 250 million miles away from the Earth.
In his fourth statement last week President Trump said, "We will return to the Moon … and, sometime soon, we will build an American flag on Mars."  The president was reported to have no patience during this time taking NASA to prepare for a returning person on the Moon. Apollo 17, the last such mission launched in December, 1972 and took the 11th and 12th men to walk there.
These plans should not be violated, but NASA's current plan returns to Americans over the Moon at the end of Donald Trump's second term. (Checking only to see if you're still reading.)
A major factor inhibiting the expanded drawing of a human space has become a concern about costs. But Gallup's latest survey found that all age groups had similar views, with 62% to 65% agreeing that the costs were reasonable.
Back in 1999 only half of Americans who were evaluated might name Neil Armstrong as the first person on the Moon. Now, that's increased to 66 percent. But a quarter of respondents also do not have a clue.
