According to those plans, the telescopes would be up and running sometime in the 2030s.
NASA and the Department of Energy backed the plan. Still, the National Science Foundation's governing board on Feb. 27 said it should limit its contribution to $1.6 billion, enough to move ahead with just one telescope. The NSF intends to present their process for making a final decision in early May, when it will also ask for an update on nongovernmental funding for the two telescopes. The ultimate arbiter is Congress, which sets the agency's budget.
America has learned the hard way that falling behind in science and technology can be costly. Beginning in the 1970s, the U.S. ceded its powerful manufacturing base, once the nation's pride, to Asia. Fast forward to 2022, the U.S. government marshaled a genuine effort toward rebuilding and restarting its factories—for advanced manufacturing, clean energy and more—with the Inflation Reduction Act, which is expected to cost more than $1 trillion.
President Joe Biden also signed into law the $280 billion CHIPS and Science Act two years ago to revive domestic research and manufacturing of semiconductors—which the U.S. used to dominate—and narrow the gap with China.
As of 2024, America is the unquestioned leader in astronomy, building powerful telescopes and making significant discoveries. A failure to step up now would cede our dominance in ways that would be difficult to remedy.
The National Science Foundation's decision will be highly consequential. Europe, which is on the cusp of overtaking the U.S. in astronomy, is building the aptly named Extremely Large Telescope, and the United States hasn't been invited to partner in the project. Russia aims to create a new space station and link up with China to build an automated nuclear reactor on the moon.
Although any sizable grant for new telescope projects is welcome, it's crucial to understand that allocating funds sufficient for just one of the two planned telescopes won't suffice. The Giant Magellan and the Thirty Meter telescopes are designed to work together to create capabilities far greater than the sum of their parts. They are complementary ground stations. The GMT would have an expansive view of the southern hemisphere heavens, and the TMT would do the same for the northern hemisphere.
The goal is "all-sky" observation, a wide-angle view into deep space. Europe's Extremely Large Telescope won't have that capability. Besides boosting America's competitive edge in astronomy, the powerful dual telescopes, with full coverage of both hemispheres, would allow researchers to gain a better understanding of phenomena that come and go quickly, such as colliding black holes and the massive stellar explosions known as supernovas. They would put us on a path to explore Earth-like planets orbiting other suns and address the question: "Are we alone?"
Funding both the GMT and TMT is an investment in basic science research, the kind of fundamental work that typically has led to economic growth and innovation in America's ecosystem of scientists, investors and entrepreneurs.
Elon Musk's SpaceX is the most recent example, but the synergy goes back decades. Basic science at the vaunted Bell Labs, in part supported by taxpayer contributions, was responsible for the transistor, the discovery of cosmic microwave background and establishing the basis of modern quantum computing. The internet, in large part, started as a military communications project during the Cold War.
Beyond its economic ripple effect, basic research in space and about the cosmos has played an outsized role in the imagination of Americans. In the 1960s, Dutch-born American astronomer Maarten Schmidt was the first scientist to identify a quasar, a star-like object that emits radio waves, a discovery that supported a new understanding of the creation of the universe: the Big Bang. The first picture of a black hole, seen with the Event Horizon Telescope, was front-page news in 2019.
Competing in astronomy has only gotten more expensive, and there's a need to concentrate on a limited number of critical projects. But what could get lost in the shuffle are the kind of ambitious projects that have made America the scientific envy of the world, inspiring new generations of researchers and attracting the best minds in math and science to our colleges and universities.
