Sister NASA Voyager 1 should be confirming execution of her periodic Magnetometer and Engineering & Science calibration subroutines via Deep Space Station 14. The quality and state of these data packages should give the Voyager engineers more information on her FDS memory status.

...and I'll add a little more detail here, because this is one of the operational differences between V2 & V1: Voyager 1 turned off her PLS instrument on 2007:032, and so no longer does a plasma calibration routine as part of her Block Routine 11, doing only MAGCAL and PESCAL!

Sister NASA Voyager 1's regular transmission of 1 minute of data from the Plasma Wave instrument subsystem (PWS) should be arriving at Deep Space Station 10 at the data rate GS-4B (2.8 kbps). Hopefully this will confirm proper encoding by the Flight Data Subsystem.

2/ ...Remember, the confirmation of the April 18 relocation of the FDS routines for encoding information at the EL-40 data rate didn't arrive on Earth until _April 20!_ Troubleshooting with a ping time of 45+ hours is very time consuming!

1/ Sister NASA Voyager 1's full memory readout from her Flight Data Subsystem (FDS) should be arriving at Deep Space Station 43 over the next 75 minutes. This will give the Voyager engineering team more information about the FDS memory relocation. Remember...

Sister ship NASA Voyager 1 is 22h 32m 31s of light travel time from Earth (2024:114:120000:1L) Today is the day V1 will again begin to draw away from Earth, so you will slowly see the One-Way Light Travel Times begin to increase again!

1/ Sister NASA Voyager 1's memory readout from both her Computer Command Subsystems A&B should be arriving at Deep Space Station 43 over the next few hours. This will give the Voyager engineering team information about the Flight Data System memory relocation. Remember...

2/ ...Remember, the confirmation of the April 18 relocation of the FDS routines for encoding information at the EL-40 data rate didn't arrive on Earth until ~1300UTC _yesterday!_ Troubleshooting with a ping time of 45+ hours is very time consuming!

Sister NASA Voyager 1's confirmation of relocating memory space for FDS encoding of engineering data at the EL-40 data rate (40 bps) should be arriving at Deep Space Station 43 over the next 4-1/2 hours.
