Maynette E. Smith works in the Safety and Mission Assurance Directorate at NASA’s John F. Kennedy Space Center in Florida. She leads a team responsible for conducting independent reviews and assessments of technical and mission risks associated with space flight programs. She began her career with NASA as a systems engineer, and in 1988, she was promoted to experiment project engineer. Part of "Women@NASA" series.
Situated at the meeting of major currents, the Galapagos Islands are not tropical, but in fact they are cold. Reefs around the islands were only discovered in 1975. With the help of a local guide, the team battles rough seas and cold water to explore the reefs. They discover some flourishing reefs at Darwin Island. Part of the "Global Reef Expedition" series.
Hydrothermal vents were originally discovered near the Galapagos Rift in 1977. They form from hot springs produced by underwater volcanoes or tectonic activity. Scientists have found an abundance and assortment of life that has adapted to the harsh, dark conditions surrounding these seafloor vents. Part of the "Deep Sea Dive" series.
Sunday, July 20th, 2014, marked the 45th anniversary of the day the world stood still and watched astronauts Neil Armstrong and Edwin "Buzz" Aldrin land on the surface of the moon. There is no question that the partnership between NASA and the United States Geological Survey (USGS) was crucial to the Apollo program's accomplishments.
On July 16, 1969, Neil Armstrong, along with Edwin E. Aldrin, Jr., and Michael Collins, blasted off in the Apollo 11 vehicle toward the Moon. Armstrong was the leader of the mission, and the first astronaut to set foot on the Moon's surface. Part of the "World Explorers" series.
Launched in the summer of 1977, Voyager was the audacious first mission that would visit all the outermost planets. This documentary tells the story of the mission through firsthand accounts of those who made the mission possible. They are a small band of resourceful, ambitious, and passionate men and women who reached for the stars and succeeded. Please note this title contains potentially offensive language and contains mature themes.
Many endangered animals are protected under the U.S. Endangered Species Act. The Endangered Species Act of 1973 is one of the most effective conservation laws in the United States. Using science-based management plans, it has prevented the extinction of 99% of the species it protects. Part of the "Endangered Ocean" series.
In 1990, when the first images from NASA's Hubble Space Telescope were too blurry to use, JPL scientists and engineers went to work to devise a fix. They created a camera with corrective vision to bring Hubble images into sharp focus. Part of the “Crazy Engineering” series.
Find out how Albert Einstein used the totality phase of the 1919 solar eclipse to prove his theory of relativity, which predicts that large objects bend “space-time” towards themselves.
Anthony Marr champions the cause of the endangered Bengal tiger, focusing on 40 tigers at an Indian national park. From 100,000 animals in 1900 to less than 5,000 today, the tigers face extinction from lack of space, poachers, desire for folk medicine, apathy, and ignorance. Shows tigers hunting, eating, resting, and with new cubs. Photography supports facts about this most exotic and revered predator. NOTE: One brief mating scene.
On May 5, 1961, Alan Shepard made a 15-minute suborbital flight in the Freedom 7 spacecraft, which reached an altitude of 115 miles. The flight came 23 days after Soviet cosmonaut Yury Gagarin became the first human to travel in space, but Shepard’s flight energized U.S. space efforts and made him a national hero. Part of the "World Explorers" series.
Fire scientist David Bowman gives a testimony of the danger of catastrophic bushfire around his hometown of Hobart, Tasmania. As record bush fires continue to plague the country, the work of Bowman and his colleagues to understand the causes and consequences of these events becomes ever more pressing. Part of WildFIRE PIRE series.
In 1977, Voyagers I and II left Earth for deep space exploration and a close-up view of the edges of our solar system. Reveals how the space shuttles used the gravitational fields from surrounding planets to slingshot themselves through the outer planets. Voyager II's graphics and real pictures of Neptune and Uranus help explain their features, axis, rings and moons, and magnetic fields. Also notes some peculiar facts about each.
Part of being an active citizen is taking care of the environment. In this episode, students learn all about the history of the environmental movement in the United States and the origins of the holiday known as Earth Day. Part of the "Constitution Hall Pass."
This national monument tells the story of the California’s Sierra Nevada Mountain Range. Established in 1911 by presidential proclamation, Devils Postpile National Monument protects and preserves the Devils Postpile formation, the 101-foot high Rainbow Falls, and pristine mountain scenery. The formation is a rare sight in the geologic world and ranks as one of the world's finest examples of columnar basalt. Its columns tower 60 feet high and display an unusual symmetry.
In this episode, host Emily Graslie interviews Dr. Robert F. Inger. His career in science spans over seventy-four years, and he published his first scientific paper in 1942. He is a renowned herpetologist. The greatest lesson he has learned is to never stop asking questions and seeking answers. Part of "The Brain Scoop" series.
What will happen to Los Angeles when the big one strikes? The answer may be found at an earthquake site over 6,000 miles away. Examines why the 7.4 earthquake that struck Izmit, Turkey, killed over 17,000 people in 1999. Explains why even trained rescuers fight an impossible battle. Offers suggestions as to what Los Angeles must do to be better prepared for the earthquake that scientists see as inevitable, and to prevent this same tragedy from happening.
When it comes to ultrafast lasers, Margaret Murnane’s name is one of the best known for her work in this field of science. Since 1999, she has been a professor at the University of Colorado’s National Science Foundation funded JILA Physics Frontier Center, where she and her husband, Henry Kapteyn, pioneer research in ultrafast x-ray science. Part of the Scientists and Engineers On Sofas Series.
Theodore Roosevelt was a great lover of nature long before he became president. From boyhood throughout his adult life, Roosevelt's enthusiasm for conservation was encouraged and shaped by several influential figures. Early on, Roosevelt's uncle, Robert Barnwell Roosevelt, inspired his nephew with his tireless struggles on behalf of conservation policy. One of his greatest political allies in the crusade to preserve America's natural beauty was Gifford Pinchot, the first chief of the U.S. Forest Service.
