SPHINX (Space Plasma High-Voltage Interaction Experiment) ist die Bezeichnung eines amerikanischen Testsatelliten der NASA.[1]
Mit Hilfe des SPHINX-Satelliten sollte der Einfluss der Strahlungsgürtel der Erde auf Raumflugkörper untersucht werden. SPINX hatte dazu vier Experimente an Bord. Dabei wurden auch verschiedene Solarzellentypen dem Weltraum ausgesetzt.[2] SPHINX wurde zudem entwickelt, um Hochspannungsgeräte im Weltraum zu testen.[3]
Missionsverlauf
Start der Titan-Rakete
SPHINX sollte am 11. Februar 1974 zusammen mit einer Attrappe der Vikinger-Sonde beim Testflug der Titan IIIE-Trägerrakete gestartet werden. Doch die Centaur-Oberstufe versagte, weswegen keine Umlaufbahn erreicht werden konnte.

First Titan-Centaur Launch Test - GPN-2003-00040.jpg
The first Titan/Centaur lifted off from Complex 41 at CapeKennedy Air Force Station at 9:48 AM EDT. The Titan stagesburned as programmed, but when the Centaur stage failed to ignite, the Range Safety Officer destroyed it. The new NASArocket was launched on a proof of concept flight designed toprepare it for twin Viking launches to Mars in 1975 and other missions involving heavy payloads. The 160-foot-tall rocket combines the Air Force Titan III with the NASA high-energyCentaur final stage. The twin solid rocket boosters have acombined liftoff thrust of 2.4 million pounds. Aboard Titan/Centaur on its proof of concept flight were a dynamic simulatorof the Viking spacecraft and a small scientific satellite(SPHINX) designed to determine how high voltage solar cells, insulators, and conductors are affected by the charges particlesin space. KSC's Unmanned Launch Operations Directorate conductedthe launch. For more information about Titan and Centaur, pleasesee Chapters 4 and 8, respectively, in Roger Launius and Dennis Jenkins' book To Reach the High Frontier published by The University Press of Kentucky in 2002.
