Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat [3]) is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral. [4]
Pale Blue Dot is a photograph of Earth taken on February 14, 1990, by the Voyager 1 space probe from an unprecedented distance of approximately 6 billion kilometers (3.7 billion miles, 40.5 AU), as part of that day's Family Portrait series of images of the Solar System.
The International Telecommunication Union defines deep space to start at a distance of 2 million km (1.2 million mi) (about 0.01 AU) from Earth's surface. NASA's Deep Space Network has variously used criteria of 16,000–32,000 km (9,900–19,900 mi) from Earth.

The Moon, the Earth-moon Lagrange points, and the Earth–Sun Lagrangian points L 1 and L 2 are all closer than 2 million km from Earth (distances are here), so they are considered near space and cannot use the ITU's deep space bands. Missions at these locations that need high data rates must therefore use the "near space" K band (27 GHz).
The Goldstone Deep Space Communications Complex (GDSCC), commonly called the Goldstone Observatory, is a satellite ground station located in Fort Irwin [1] in the U.S. state of California. Operated by NASA 's Jet Propulsion Laboratory (JPL), its main purpose is to track and communicate with interplanetary space missions .

Webb's First Deep Field was taken by the telescope's Near-Infrared Camera (NIRCam) and is a composite produced from images at different wavelengths, totalling 12.5 hours of exposure time. [3] [4] SMACS 0723 is a galaxy cluster visible from Earth's Southern Hemisphere, [5] and has often been examined by Hubble and other telescopes in search of ...
