The U.S. Tracking and Data Relay Satellite System (TDRSS, pronounced "T-driss") is a network of American communications satellites (each called a tracking and data relay satellite, TDRS) and ground stations used by NASA for space communications. The system was designed to replace an existing network of ground stations that had supported all of ...
Launched in November 1967, the ATS-3 was in service for 11 years before finally being decommissioned in 1978 along with ATS-1. [6] Among its widest-known achievements are the first full-disk, "true color" [7] composite Earth image (DODGE took color-filtered black-and-white images, put together they produced the very first color image of the full-disk). [8]
The satellite's development was fast-tracked and completed in a record 15 months, [41] partly due to using reconfigured Chandrayaan-2 orbiter bus. [42] Despite the US federal government shutdown, NASA reaffirmed on 5 October 2013 it would provide communications and navigation support to the mission "with their Deep Space Network facilities.".
The Cosmic Background Explorer (COBE / ˈ k oʊ b i / KOH-bee), also referred to as Explorer 66, was a NASA satellite dedicated to cosmology, which operated from 1989 to 1993.Its goals were to investigate the cosmic microwave background radiation (CMB or CMBR) of the universe and provide measurements that would help shape our understanding of the cosmos.
In September 1969, the Space Task Group, under the leadership of U.S. Vice President Spiro Agnew, issued a report calling for the development of a space shuttle to bring people and cargo to low Earth orbit (LEO), as well as a space tug for transfers between orbits and the Moon, and a reusable nuclear upper stage for deep space travel.
Earth Observing-1 (EO-1) was a NASA Earth observation satellite created to develop and validate a number of instrument and spacecraft bus breakthrough technologies. It was intended to enable the development of future Earth imaging observatories that will have a significant increase in performance while also having reduced cost and mass.
Earth's spacecraft cemetery is used as a site for spacecraft that have reached their lifetime limit due to fatigue and must be retired. [16] Larger spacecraft too massive to burn up during re-entry into the Earth's atmosphere are controlled to crash / splash down in Earth's spacecraft cemetery, a location in the ocean remote from inhabited regions.

On 11 January 2007, China conducted an anti-satellite missile test. A Chinese weather satellite—the FY-1C (COSPAR 1999-025A) polar orbit satellite of the Fengyun series, at an altitude of 865 kilometres (537 mi), with a mass of 750 kilograms (1,650 lb) [1] —was destroyed by a kinetic kill vehicle traveling with a speed of 8 km/s (18,000 mph) in the opposite direction [2] (see Head-on ...
