The Voyager Golden Record contains 116 images and a variety of sounds. The items for the record, which is carried on both the Voyager 1 and Voyager 2 spacecraft, were selected for NASA by a committee chaired by Carl Sagan of Cornell University. Included are natural sounds (including some made by animals), musical selections from different ...
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, ( cosmic) - radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and ...
The Demon-Haunted World: Science as a Candle in the Dark is a 1995 book by the astrophysicist Carl Sagan. (Four of the 25 chapters were written with Ann Druyan ). [1] : x In it, Sagan aims to explain the scientific method to laypeople and to encourage people to learn critical and skeptical thinking. He explains methods to help distinguish ...
Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy , predates reliable recorded history , it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to ...
Limited funding ended the Grand Tour program, but elements were incorporated into the Voyager Program, which fulfilled many of the flyby objectives of the Grand Tour except a visit to Pluto. Voyager 2 was the first to be launched. Its trajectory was designed to allow flybys of Jupiter, Saturn, Uranus, and Neptune.
Space physics – study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System. Solar physics – Sun and its interaction with the remainder of the Solar System and interstellar space. Stellar astronomy – concerned with Star formation, physical properties, main sequence life span, variability ...
According to the United States National Center for Education Statistics, "scientific literacy is the knowledge and understanding of scientific concepts and processes required for personal decision making, participation in civic and cultural affairs, and economic productivity". [2] A scientifically literate person is defined as one who has the ...
Plants in space. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens. [1] In the context of human spaceflight, they can be ...
