    Another DSP satellite was lost in 1999, DSP-19, after its Inertial Upper Stage failed following launch from a Titan 4B booster. [8] DSP-19 was a USAF Defense Support Program missile early warning satellite equipped with an infrared telescope to detect rocket launches. The Titan 4B rocket placed the IUS upper stages and payload into a 188 km x ...

    Based on its experiences with the launching of short-range theater missiles by Iraq during the 1991 Persian Gulf War, the U.S. Department of Defense (DoD) concluded that expanded theater missile warning capabilities were needed, and it began planning for an improved infrared satellite sensor capability that would support both long-range strategic and short-range theater ballistic missile ...

    Sensors on Earth observation satellites often take measurements of emitted energy over some portion of the electromagnetic spectrum (e.g., UV, visible, infrared, microwave, or radio). [ 1 ] The invention of climate research through the use of satellite remote telemetry began in the 1960s through development of space probes to study other planets.

    Four GOES satellites are available for operational use. GOES-14 is in storage at 105° W. The launch of this satellite, which was designated GOES-O before orbiting, was delayed several times. [11] [12] It was launched successfully on 27 June 2009 from Space Launch Complex 37, on a Delta IV Medium rocket, [13] a Delta IV M+ (4,2).

    The satellite's data can still be used, until it ceases pointing the sensors towards the Earth. The satellite was the most recent on-orbit, having been launched on 3 April 2014. [12] The failure only left F16, F17 and F18 – all significantly past their expected 3–5 year lifespan – operational.
