DSCOVR takes full-Earth pictures about every two hours and is able to process them faster than other Earth observation satellites. [23] The spacecraft is in a looping halo orbit around the Sun-Earth Lagrange point L1 in a six-month period, with a spacecraft–Earth–Sun angle varying from 4° to 15°. [24] [25]
DSCOVR is unofficially known as GORESAT, because it carries a camera always oriented to Earth and capturing full-frame photos of the planet similar to the Blue Marble. This concept was proposed by then-Vice President of the United States Al Gore in 1998 [4] and was a centerpiece in his 2006 film An Inconvenient Truth. [5]

Currently, an artificial satellite called the Deep Space Climate Observatory (DSCOVR) is located at L 1 to study solar wind coming toward Earth from the Sun and to monitor Earth's climate, by taking images and sending them back. [3] The James Webb Space Telescope, a powerful infrared space observatory, is located at L 2. [4]
NASA has blasted a spacecraft, traveling at speeds up to 92,000 mph, to the most mysterious asteroids in our solar system.Called the Trojan asteroids, they are trapped in two swarms — one in ...
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.
Animation of Advanced Composition Explorer's orbit viewed from the Sun Earth · Advanced Composition Explorer ACE in orbit around the Sun–Earth L 1 point. Advanced Composition Explorer (ACE or Explorer 71) is a NASA Explorer program satellite and space exploration mission to study matter comprising energetic particles from the solar wind, the interplanetary medium, and other sources.
