But proposed budgets drastically cut support for telescopes that tell us about the universe’s origins and spacecraft that trace the changes on our home planet. And the United States has stood on the sidelines as nations across the world develop the next generation of land-based optical observatories.
Rarely has there been a more exciting and promising time for space science. Telescopes pointing deep into space detect thousands of planets orbiting faraway suns. Life may reside in the ocean worlds of the moons of Jupiter and Saturn or be revealed in the ancient history of Mars. Gravitational-wave observatories probe the inner workings of black holes, like the one at the center of our galaxy. We have the opportunity to understand the origins of dark matter and dark energy, which constitute 95 percent of the universe but remain mysterious. The United States has been a remarkable engine of innovation, creating knowledge for the ages and solving society’s problems today. We have the talent and the entrepreneurial spirit to build on our grand history of discovery. We need only the vision and the will.
