NASA announced the selection of four candidate Small Explorer missions: the Joint Ultraviolet Night Sky Observer (JUNO), the Positron Electron Magnetic Spectrometer (POEMS), the Transitional Region and Coronal Explorer (TRACE), and the Wide-Field Infrared Explorer (WIRE). The four proposed missions were scheduled to enter a ten-month definition phase. After that phase, NASA planned to confirm two missions for development and flight and to launch the confirmed missions in 1997 and 1998. (NASA Release 93-168).
NASA officials announced that further testing on the Wide Field/Planetary Camera II (WF/PCII), an instrument scheduled to fly on the Hubble Space Telescope Servicing Mission in December, might be necessary. Tests had cleared the camera of suspicion that it was flawed, but NASA asked for one last independent review of the data just to make completely sure. (NASA Release 93-169; W Post, Sep 28/93)
