The use of data collected by the public makes the program an example of citizen science. [2] Globe at Night began as a NASA educational program in the US organized by the NOAO, and was expanded internationally during the 2009 International Year of Astronomy; [3] it is an offshoot of the GLOBE Program, which focuses on school-based science ...
NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather ...
The Earth Impact Database is a database of confirmed impact structures or craters on Earth. It was initiated in 1955 by the Dominion Observatory , Ottawa, under the direction of Carlyle S. Beals . Since 2001, it has been maintained as a not-for-profit source of information at the Planetary and Space Science Centre at the University of New ...
He pointed out that the human body contained a Yottabyte of data to be transported. Writing in 1995 he also pointed out that to store this amount of data in 1995 would involve a pile of hard drives that "From Earth, you'd have to stack 100-gigabyte hard drives a third of the way to the center of the Milky Way or so to hold it all.
A graphical or bar scale. A map would also usually give its scale numerically ("1:50,000", for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters) A bar scale with the nominal scale expressed as "1:600 000", meaning 1 cm on the map corresponds to 600,000 cm=6 km on the ground.
Global-scale Observations of the Limb and Disk (GOLD) is a heliophysics Mission of Opportunity (MOU) for NASA's Explorers program. [6] Led by Richard Eastes at the Laboratory for Atmospheric and Space Physics, which is located at the University of Colorado Boulder, GOLD 's mission is to image the boundary between Earth and space in order to answer questions about the effects of solar and ...
As the permanent archive, NSSDCA teams with NASA's discipline-specific space science "active archives" which provide access to data to researchers and, in some cases, to the general public. NSSDCA also serves as NASA's permanent archive for space physics mission data. It provides access to several geophysical models and to data from some non ...
