Lori Garver: Forget new manned missions in space. NASA should focus on saving Earth.

NASA was not created to do something again. It was created to push the limits of human understanding — to help the nation solve big, impossible problems that require advances in science and technology. Fifty years ago, the impossible problem was putting a human on the moon to win the space race, and all of humanity has benefited from the accomplishment.

The impossible problem today is not the moon. And it's not Mars. It's our home planet, and NASA can once again be of service for the betterment of all.

Let’s remember our history. We went to the moon 50 years ago in response to the Soviet Union’s perceived domination of spaceflight. The 12 Americans who walked on the moon brought back 842 poundsof lunar material (rocks and dust), learned about our closest planetary body’s geology and gave us a view of the Earth that changed our perspective. But that’s not what drove NASA spending to 4 percent of the federal budget in 1965. We were willing to stake so much on the moon landing — only because there was so much at stake.

After accomplishing this amazing feat, the aerospace community has again and again sought presidential proclamations to go further. President Donald Trump is the fifth president to proclaim we will send humans to the moon and/or Mars within a specific time frame, a decree without a value proposition that has never inspired broad public support nor come close to coming true.

NASA remains one the most revered and valuable brands in the world, and the agency is at its best when given a purpose. But the public doesn’t understand the purpose of spending massive amounts of money to send a few astronauts to the moon or Mars. Are we in another race, and if so, is this the most valuable display of our scientific and technological leadership? If science is the rationale, we can send robots for pennies on the dollar. In a JulyPew Research Center study, 63 percent of respondents said monitoring key parts of Earth’s climate system should be the highest priority for the United States’ space agency — sending astronauts to the moon was their lowest priority, at 13 percent; 18 percent favor Mars.

The public is right about this. Climate change - not Russia, much less China - is today’s existential threat. Data from NASA satellites show that future generations here on Earth will suffer from food and water shortages, increased disease and conflict over diminished resources. In 2018, the National Academy of Sciences released its decadal survey for Earth science and declared that NASA should prioritize the study of the global hydrological cycle; distribution and movement of mass between oceans, ice sheets, ground water and atmosphere; and changes in surface biology and geology. Immediately developing these sensors and satellites while extending existing missions would increase the cadence of new, more precise measurements and contribute to critical, higher-fidelity climate models.

NASA could also move beyond measurement and into action — focusing on solutions for communities at the front lines of drought, flooding and heat extremes. It could develop and disseminate standardized applications that provide actionable information to populations that are the most vulnerable. NASA could create a Climate Corps — modeled after the Peace Corps — in which scientists and engineers spend two years in local communities understanding the unique challenges they face, training local populations and connecting them with the data and science needed to support smart, local decision-making.

The fragmented system of roles and responsibilities related to handing the massive amounts of Earth science data is severely hampering global efforts required to make significant progress. The U.S. government role in addressing this challenge is foundering without leadership. Standardizing data collection and coordinating its storage, analysis and distribution require experience working across disciplines, government agencies and universities as well as the private sector and international community. Only NASA has done this sort of thing before; only NASA has the credibility and expertise to do it again.

Assigning NASA this task would require an Apollo-scale change — but could be accomplished within its existing mandate and by shifting funding priorities. The National Aeronautics and Space Act of 1958 supports expansion of human knowledge of the Earth and phenomena in the atmosphere and directs the agency to develop and carry out a comprehensive program of research, technology and monitoring to understand and maintain the integrity of the Earth’s atmosphere. The act requires NASA to work with other federal agencies, academia and the private sector to make the necessary observations, disseminate their results and enlist the support and cooperation of appropriate scientists and engineers of other countries and international organizations.

Apollo's legacy should not be more meaningless new goals and arbitrary deadlines. Let's not repeat the past. Let's try to save our future. Besides, humanity's intrinsic need to explore is driven by our need to survive.
