One frame of high-rate Plasma Wave (PWS) data was recorded on June 26. High-rate Ultraviolet Spectrometer (UVS) observations were conducted on HD 200120 on June 22, and on HD 206165 on June 26 and 28, and on HR 264 on June 28. There was sufficient Deep Space Network (DSN) coverage to capture all of the data. On June 25 an AGC/Command test was performed over the 34 meter antenna in Australia (DSS 42) and downlinked over the 34 meter antenna in Goldstone, California (DSS 12). The test indicated that there has been no apparent change in the spacecraft receiver or command threshold since launch. Also on June 25 the Attitude and Articulation Control Subsystem (AACS) Sun Sensor heater B was powered on and heater A turned off; the heater switch was made to avoid a Sun Sensor low temperature limit violation. Following stabilization, the Sun Sensor temperature was +4 degrees C above the predicted value. A pre Computer Command Subsystem-B (CCSB) Refresh checksum was downlinked from the spacecraft on June 27; real-time commands were subsequently transmitted to initiate the CCSB refresh activity and reset the CCS status telemetry. Successful completion of the refresh, which included the area of memory in which the Command Processor and Error routines reside, was verified by the received checksum value; the CCS status telemetry reset was also successful. A Magnetomter Calibration (MAGCAL) was conducted on June 28. Data quality was good. Cruise data appeared normal for the Fields & Particles instruments on Voyager 1. Voyager 2 The Voyager 2 spacecraft also continue to collect routine cruise science data. On June 26, memory readouts of the AACS, CCS, and FDS were performed and one frame of high-rate PWS data was recorded. On June 25, in the continuing checkout of the Voyager Interstellar Mission (VIM-5) Flight Data Subsystem (FDS) program, two-frame AACS memory readouts were performed in two formats in the UV5A data mode. Spacecraft and Ground Data Subsystem (GDS) performance were nominal. On June 27 a real-time command file was transmitted to patch the FDS VIM-5 program. This patch was made to correct an FDS software error which would have resulted in the loss of science data. The memory modification was verified by FDS checksum. Full AACS, CCS, and GDS memory readouts were executed on June 26 while in the EH12 data mode. These memory readouts were also recorded and will be used for further checkout of the VIM-5 program, when they are played back on July 12, in the PB 15 data mode. Memory compare requests were submitted for the readouts' the CCS and FDS readout compares have been returned and indicate the memory contents are as expected. There is currently no visibility into near-real-time science data on Voyager 2. Approximately half of the investigator teams have reported on the status of the new CR5T and UV5A data modes from their analyses of tapes. These reports indicate the science data investigated so far are correctly formatted. Several of the status channels on four of the science instruments continue to be incorrect on Voyager 2.

Why not call up Congressman Walker's staff person on this; his name is Barry Beringer (202-225-8500). Tell him you would like to help and ask what needs to be done. He would love to hear form you (you are after all, helping him do his job for free). After you find out, post a note and tell the rest of us. Allen | | In War: Resolution | | Allen W.

Do they have some Joe Schmoe working on building it with hand tools or something? Jeez. You can accomplish one hell of a lot in a year, and making an umbilical to connect the shuttle to the tank doesn't seem like it could possibly take that long. -- Michael V.

Anyway, I reiterate, what good does that do the West? It is not motivating the congressional leaders or private industry. I commend them for doing what we should be.
