The twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-40-year journey since their 1977 launches, they each are much farther away from Earth and the sun than Pluto. In August 2012, Voyager 1 made the historic entry into interstellar space, the region between stars, filled with material ejected by the death of nearby stars millions of years ago. Voyager 2 entered interstellar space on November 5, 2018 and scientists hope to learn more about this region. Both spacecraft are still sending scientific information about their surroundings through the Deep Space Network, or DSN.

Scientists first discovered hydrothermal vents in 1977 while exploring an oceanic spreading ridge near the Galapagos Islands. To their amazement, the scientists also found that the hydrothermal vents were surrounded by large numbers of organisms that had never been seen before. These biological communities depend upon chemical processes that result from the interaction of seawater and hot magma associated with underwater volcanoes.

Sally Ride was the first American woman to fly in space. For fun, she liked to run. She also played tennis, volleyball and softball. Ride wrote science books for children. The books are about exploring space.

Scientists first discovered hydrothermal vents in 1977 while exploring an oceanic spreading ridge near the Galapagos Islands. These explorers were amazed to not only find life thriving in these hostile environments, but also to find species never seen before in any other place on the planet. Most hydrothermal vents occur in the deep sea, where there is no sunlight, so life that lives on and around hydrothermal vents depends upon chemosynthesis, a chemical process that results from the interaction of seawater and hot magma associated with underwater volcanoes.

The program drew 23 undergraduates and two graduate students, many of whom are considering careers in the health sciences. The students last May visited olive groves, wineries, museums, and historic sites. They attended lectures on the history and evolution of the Mediterranean lifestyle. And they met, cooked, and dined with locals, learning how to prepare balanced and nutritious meals.

NSF takes over support of the deep-sea research submersible Alvin. Built for the Navy in 1964 and still working today, Alvin will discover life in the extreme environment of deep-sea vents in 1977 and complete its 5,000th dive in 2018.

Stever received his undergraduate degree from Colgate University and his Ph.D., in 1941, from the California Institute of Technology, with a thesis on the lifetime of the mason, a subatomic particle. During World War II, he conducted research at the Radiation Laboratory at the Massachusetts Institute of Technology and served as science liaison in Europe for the Office of Scientific Research and Development. He joined the faculty of MIT in 1946 and remained there until 1965, when he became president of Carnegie Mellon University. He was president of Carnegie Mellon and a member of the National Science Board when he was selected to be NSF's director.

Richard C. Atkinson served as the fifth director of the National Science Foundation, from May 1977 to June 1980. Atkinson assumed the position of director already well versed in the challenges of leading the only federal agency dedicated to the support of basic research and education in all fields of science and engineering. He was the first director to have served as deputy director (from 1975 to 1976), and he also served as acting director from August 1976 to May 1977 upon the departure of H. Guyford Stever. As an internationally recognized experimental psychologist and applied mathematician, Atkinson was the first NSF director with a background in social science. In the face of vocal critics in Congress and the media, Atkinson defended NSF's commitment to basic research. During his tenure as director, he negotiated a historic scientific exchange between the United States and the People's Republic of China and strengthened NSF's peer review process.

Atkinson has received many awards and honors throughout his distinguished career. In 1974, he was elected to the National Academy of Sciences, the American Academy of Arts and Sciences, and the National Academy of Education. In 1989, he served as president of the American Association for the Advancement of Science. In 2003, he won the National Science Board's prestigious Vannevar Bush Award, an award he established in 1980 during his tenure as director, for his lifetime contributions to the nation in science and technology. Atkinson also has the distinction of having a mountain in Antarctica named in his honor.

Suresh graduated from IIT with a first-class degree in mechanical engineering in 1977 and from Iowa State University with a master's degree in 1979. He subsequently earned a doctorate in mechanical engineering at the Massachusetts Institute of Technology in 1981, specializing in material sciences. Suresh then moved to Berkeley, California, for a two-year post-doctoral research fellowship at the University of California and Lawrence Berkeley National Laboratory.

Voyager stood as a greater challenge. A four-planet "grand tour" was theoretically possible. But design was crucial. A single spacecraft might accomplish the mission, but would have to be extraordinarily complex and expensive to travel to the outer reaches of the solar system, endure for more than a decade, and reliably operate a range of scientific instruments. To simplify the mission and limit the expense, the mission relied on two Voyager spacecraft to conduct intensive flyby studies only of Jupiter and Saturn-in effect repeating on a more elaborate scale the flights of the two Pioneers. With an $865 million budget, engineers designed the two Voyagers to conduct as much science and to last as long as possible. Launched from the Kennedy Space Center, Voyager 2 lifted off on August 20, 1977 and Voyager 1 on September 5, 1977, each taking different trajectories to the outer planets.

Another approach used is food pattern modeling. The 2005 Advisory Committee was the first to introduce this approach to help the Committee describe the types and amounts of foods to eat that can provide a nutritionally adequate diet. This approach was also used and expanded by the 2010 and 2015 Advisory Committees and included modeling of multiple types of diets informed by the science. The 2020 Advisory Committee continued the use of food pattern modeling, carrying forward these types of eating patterns and exploring eating patterns for toddlers for the first time.

In the search for extraterrestrial life, scientists are turning to our own ocean for inspiration. NASA has begun to help fund some deep-sea explorations, and some astrobiologists have teamed up with marine biologists and oceanographers to probe the boundaries of biology here on Earth. Exploring the unfamiliar environments in the deep sea reveals tangible guideposts for exploring space. But it also emboldens scientists to stretch their thinking and open their minds to the impossible.

After several appointments at universities around the country, Murray decided to devote her life to her Christian beliefs. In 1977, Murray became the first African American woman to be ordained as an Episcopal priest. She worked in a parish in Washington, D.C., based in ministry to the sick until her retirement in 1982. Murray died of pancreatic cancer in Pittsburgh, Pennsylvania, on July 1, 1985.

Human persecution and habitat loss have endangered large carnivore populations worldwide, but some are recovering, exacerbating old conflicts. Carnivores can injure and kill people; the most dramatic form of wildlife-human conflict. In Scandinavia, the brown bear (Ursus arctos) population increased from ~500 bears in 1977 to ~3300 in 2008, with an increase in injuries, fatalities, and public fear of bear attacks. We reviewed media coverage and interviewed victims to explore how bear population trends, hunter education, and other factors may have influenced the number of injuries and fatalities in Scandinavia from 1977 to 2016. We found 42 incidents with 42 injuries and 2 fatalities; 42 were adult men, one was an adult woman conducting forestry work, and one was a boy skiing off-piste. Thirty-three adult men were hunting bears, moose, or small game, often with a hunting dog, and 26 had shot at the bear at 811 m before injury. Eleven nonhunters were conducting forestry work, inspecting a hunting area, picking berries, tending livestock, hiking, harassing a denned bear, and one person was killed outside his house at night. Eight of the 11 incidents of nonhunters involved female bears with cubs; three of these family groups were in dens and two were on carcasses. The annual number of hunters injured/killed was mostly influenced by the increase in the bear population size. The pattern was similar regarding injuries/fatalities to other outdoor users, but the relation with the bear population size was weaker than for hunters, and the null model was equally supported. Bear physiology at denning may make encounters with bears more risky in the fall, when bears show prehibernation behavior. Awareness and education efforts, especially among hunters, seem important to ensure human safety. Recreationists and forestry workers should avoid dense vegetation or make noise to warn bears of their presence. 006ab0faaa
