If the United States commits to the goal of reaching Mars, it will almost certainly do so in reaction to the progress of other nations - as was the case with NASA, the Apollo program, and the project that became the International Space Station.
Interpretation
The quote emphasizes that the U.S. space exploration efforts are often motivated by competition and progress made by other nations.
Neil Degrasse Tyson's quote suggests that the pursuit of ambitious goals, such as reaching Mars, is typically driven by a response to the advancements made by international competitors. Historically, the United States' achievements in space exploration, including the Apollo program and the development of the International Space Station, were catalyzed by the need to respond to the technological developments of other countries. This underscores the importance of competition in pushing the boundaries of innovation and exploration.
In practice
In a speech about future space missions, one might quote Tyson to emphasize the need for national commitment to space exploration.
The problem is that many people operate on the assumption that NASA should go to Congress every year with hat in hand and justify it every year. Well, I see it as the greatest economic driver that there ever was. Economic drivers don't need justification.
The press still thinks [global warming] is controversial. So they find the 1% of the scientists and put them up as if they're 50% of the research results. You in the public would have no idea that this is basically a done deal and that we're on to other problems, because the journalists are trying to give it a 50/50 story. It's not a 50/50 story. It's not. Period.
As a scientist, I want to go to Mars and back to asteroids and the Moon because I'm a scientist. But I can tell you, I'm not so naive a scientist to think that the nation might not have geopolitical reasons for going into space.
In just one year, the expenditure of of the U.S.'s military budget is equivalent to the entire 50-year running budget of NASA combined.
One of my great laments is that education today seems to have... be less about passion and more about process, more about tactic or technique.
Lots of people think, well, we're humans; we're the most intelligent and accomplished species; we're in charge. Bacteria may have a different outlook: more bacteria live and work in one linear centimeter of your lower colon than all the humans who have ever lived. That's what's going on in your digestive tract right now. Are we in charge, or are we simply hosts for bacteria? It all depends on your outlook.
Oh leave the Wise our measures to collate. One thing at least is certain, light has weight. One thing is certain and the rest debate. Light rays, when near the Sun, do not go straight.
The unity of all science consists alone in its method, not in its material.
The universe is almost like a huge magic trick and scientists are trying to figure out how it does what it does.
Subatomic particles do not exist but rather show 'tendencies to exist', and atomic events do not occur with certainty at definite times and in definite ways, but rather show 'tendencies to occur'.
Science is the topography of ignorance.
I love science fiction. There are ways in which this community kept me and my partner alive through some very, very bad years, and I will always acknowledge that.
