Earth's location in the Universe. Universe – all of time and space and its contents.. Observable universe – spherical region of the Universe comprising all matter that may be observed from Earth at the present time, because light and other signals from these objects have had time to reach Earth since the beginning of the cosmological expansion.
The Blue Marble is a photograph of Earth taken on December 7, 1972, by either Ron Evans or Harrison Schmitt aboard the Apollo 17 spacecraft on its way to the Moon.Viewed from around 29,400 km (18,300 mi) from Earth's surface, [1] a cropped and rotated version has become one of the most reproduced images in history.

NASA brought the Orion spacecraft back to life from the defunct Constellation program and successfully test-launched the first capsule on December 5, 2014, aboard EFT-1. After a near-perfect flight traveling 3,600 miles (5,800 km) above Earth, the spacecraft was recovered for study.
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
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 ...
NASA FACTS was a collection of NASA's science series which is intended as an "easy-to-understand explanations of scientific phenomena involved in projects undertaken by NASA. The NASA FACTS Science Series was published frequently [ when? ] at irregular intervals, each presenting "an analysis of a particular subject within program perimeters and ...
