VORTEX Instrument, 1977 [photograph].

Vortex D.V.U. Optical Bench , 9 May 1977. [Description from photo index.]. In addition to the missions that JPL has developed and managed for NASA, there are also missions which have been managed by other NASA centers and JPL has provided scientific instruments. The Pioneer Venus mission was managed by Ames Research Center near Mountain View, California. It included an orbiter, launched on May 20, 1978 and a bus with four atmospheric probes which was launched on August 8, 1978. The orbiter (Pioneer Venus 1) arrived on December 4, 1978 and the multiprobe (Pioneer Venus 2) arrived 5 days later, to collect scientific data about the atmosphere of the planet. JPL provided five instruments for Pioneer Venus, including the Venus Orbiter Radiometric Temperature EXperiment (VORTEX), also known as the Orbiter Infrared Radiometer (OIR). Oxford University provided the pressure modulator (and principal investigator F.W. Taylor). The photo above shows the finished VORTEX instrument without its housing. The Section 321 photo album shows various steps in the fabrication, assembly and testing of the instrument, through May 1977. (JPL internal access only). Photo 321-692 shows a drawing done in November 1975, when the instrument was under development.

One of the first people hired at GALCIT Project #1 in November 1941 was photographer George Emmerson (1913-1994), an emigrant from Newcastle, Great Britain. Audrey Voice and Mary J. Taylor as photographer's assistants joined Emmerson in 1943. Emmerson took almost all the early photos that became a part of this collection, a collection described in brief as the work product of the JPL Photolab. As JPL grew, so did the assignments to the Photolab to photograph all Laborato...
