50th Anniversary of the Historic Apollo 11 Mission to the Moon

“A grand attempt to reach beyond the world of mundane life and transcend the ordinary limits of human existence through accomplishment of the miraculous – a story of engineers who tried to reach the heavens.”
The Spaceflight Revolution, William Bainbridge

Fifty years ago, six hundred million people watched in awe as Commander Neil Armstrong took mankind’s first steps on lunar soil. For eight days, Apollo 11 carried Commander Neil Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin “Buzz” Aldrin through space, as they made celestial observations that served as the foundation of previously inconceivable human exploration beyond planet Earth. For 21 ½ hours, Armstrong and Aldrin explored the Moon’s surface, gathering 47.5 pounds of Moon rocks to bring home, communicating back to Earth through thousands of miles of cosmic dust, and chronicling their experiences to share with the world. This milestone in human history marked an age of significant technological achievement, space exploration, and discovery, and inspired the world with possibilities of the future. This week, we commemorate the 50th anniversary of the Apollo 11 mission to the Moon.

Since Armstrong’s famous words, “one small step for a man, one giant leap for mankind,” travelled thousands of miles from the lunar surface to Earth, there have been many new discoveries and conclusions regarding space, technology, and humanity. Astronaut-driven lunar rovers and other specialized equipment such as the Modularized Equipment Transporter (MET) enable astronauts to conduct longer, more in-depth geological surveys of different locations on the Moon’s surface. Project Apollo, spanning from 1961–1975, not only accelerated scientific discovery, but also further developed society’s understanding of our own place within the cosmos. 50 years later, we ask ourselves: where do we go from here?

On December 11, 2017, President Donald Trump signed Space Policy Directive-1 (SPD-1). This new directive instructed the Administrator of the National Aeronautics and Space Administration (NASA) to lead a program of exploration with commercial and international partners to enable human expansion across the solar system and bring back to Earth new knowledge and opportunities. Beginning with missions beyond low-Earth orbit, the United States will lead the return of humans to the Moon for long-term exploration and utilization, followed by human missions to Mars and other destinations.

In response to and in support of the vision expressed in SPD-1, the National Academies released a report that reviewed decadal and other community-guided lunar science priorities as context for NASA’s current lunar plans and evaluated the actions being taken by NASA’s Planetary Science Division (PSD) to support lunar science. At the request of NASA PSD, the National Academies released a second report that explores plans for commercial partnerships, lunar infrastructure development, and related aspects of NASA’s lunar science and exploration initiative. In celebration of the 50th anniversary of one of the most important days in human history, and to learn more about innovations in space technology, read online or download our reports.

The Nation’s Science Report Card: Perspectives from the Board on Science Education

On the National Assessment of Educational Progress 2009 Science Report Card released last Tuesday, the United States received an overall grade of “needs improvement.” The test, which measures science proficiency, was administered to 4th, 8th, and 12th graders and underscores one of the major focal points of President Obama’s State of the Union address: the need to improve science education in the United States. Four in ten 12th grade students did not perform even at a basic level of science understanding, and only about a fifth were judged to be proficient in science, with just 1% performing at an advanced level. Furthermore, there is still a strong gap in the achievement of students based on ethnicity, educational attainment of parents and caregivers, and family income. The National Research Council’s Board on Science Education has produced a number of reports that discuss research and provide practical guidance to improve science education. We asked Tom Keller, Senior Program Officer with the board, for his thoughts.

“There has not been such momentum in science education in this country since the 1960s, and in contrast to the times when the nation responded to the Sputnik shock, we now know much more about effective science learning and teaching. Foundational work has been and is underway in the National Academies’ Board on Science Education (BOSE) that summarizes the enormous progress we have made through learning and education research over the last 20 years. BOSE published two seminal studies and their derivative products in two major areas of science learning: K-8 in schools, and the whole area of out-of-school or informal science learning. The report on learning science in K-8 classrooms, Taking Science to School: Learning and Teaching Science in Grades K-8, and the associated practitioner volume Ready, Set SCIENCE!: Putting Research to Work in K-8 Science Classrooms have become important resources for classroom-based science teaching. The two reports on learning science in informal environments, Learning Science in Informal Environments: People, Places, and Pursuits, and its practitioner volume Surrounded by Science: Learning Science in Informal Environments are beginning to influence how museums, science centers, zoos and aquariums, and other institutions of informal learning think about their products for their public. Taking Science to School cites the research evidence and builds the case for the teaching and learning of more rigorous content than has been the usual. And proficiency has been defined as encompassing four strands of scientific proficiency – understanding scientific explanations, generating scientific evidence, reflecting on scientific knowledge and participating productively in science. Science is not just a body of facts; it is what you know, how you use that knowledge and how that knowledge helps you understand the world. The reports on informal learning expanded on these four strands of science proficiency by acknowledging more specifically the role of interest and motivation, and by addressing the crucial role of identity as a science learner.

“A number of factors are converging, leading to an unprecedented effort in science and STEM (Science, Technology, Engineering and Mathematics) education. Just recently, the Carnegie Corporation and the Institute for Advanced Studies released the Opportunity Equation, which lays out a framework for aligning the entire science education enterprise. The Council of Chief State School Officers and the National Governors Association led the creation of the Common Core State Standards Initiative in English language arts and mathematics. The president initiated the Race to the Top education reform efforts, Educate to Innovate, and Change the Equation. The President’s Council of Advisors in Science and Technology and the National Science Board each put forth their reports on K-12 science education. The National Academy of Sciences/National Research Council is currently finalizing a framework for next generation science standards and is working in a unique partnership with AAAS, NSTA, and Achieve on the framework and standards.”

National Research Council publications can certainly inform discussions and promote science education to move us from a “needs improvement” category to “clearly outstanding,” though it will take effort throughout the entire education system to get us there.

New Planets, New Possibilities in Space Research

On Monday a team of NASA astronomers announced the discovery of the first rocky planet orbiting a star outside our solar system. The discovery of the planet, named Kepler-10b, was the result of data collected by the Kepler spacecraft, launched by NASA in March 2009.

Remember when grade school astronomy consisted mainly of knowing the names of the nine planets in order from the sun? We have come a long way from the astronomy taught to us even 10 years ago. In recent decades, significant progress in the fields of astronomy and astrophysics has brought about a revolution in understanding of the origins and nature of our universe. Hundreds of planets of startling diversity have been discovered orbiting distant suns. Black holes, once viewed as exotic theoretical possibilities, are now known to be present at the center of most galaxies, including our own. Precision measurements of the primordial radiation left by the big bang have enabled astronomers to determine the age, size, and shape of the universe. Recent discoveries, powerful new ways to observe the universe, and bold new ideas to understand it have created unprecedented scientific opportunities.

So how can we make the most of these opportunities to better understand our universe? New Worlds, New Horizons in Astronomy and Astrophysics, a new book from the National Research Council, outlines a plan for ground- and space- based astronomy and astrophysics for the coming decade. This book, based on comprehensive input from the astronomy and astrophysics community, presents exciting yet realistic recommendations.

A companion volume, Panel Reports–New Worlds, New Horizons in Astronomy and Astrophysics features a collection of reports on various sub-areas of astronomy and astrophysics. Each of these reports played an important role in setting overall priorities.

These titles and others can guide future research and decision making.
