May Jun Jul COMMENTS

All spacecraft subsystems performing nominally. The 3rd Venus gravity assist was conducted 11 July and TCM-15 was executed 19 July – both highly accurate. Orbit 5 concluded on 2 August. On 9 April, following a detection of stale telemetry from Electronics Control Unit A (ECU-A), the spacecraft’s fault protection autonomously Technical G G G transitioned to ECU-B and is functioning nominally. ECU-A appears be fully functional. The issue appears to be the same as seen during a pre-flight test, and was found to be a problem in the firmware. Put the vendor under contract to support the investigation. Collected data to compare operations of ECUs-A and –B. Low-rate data is indicative of a healthy ECU-A, but the team will analyze the high-rate data after downlink in the next Ka-band period (starting 14 August). Orbit 6: Spacecraft began orbit 6 on 2 August; will continue until 2 November The next Ka-band period will be 14-17 August Encounter 6 is 21 September-2 October, with closest perihelion to date, 20 RS, on 27 September Pre-encounter 6 Review: 18 August.

The status will be changed from G/Y to G once we have also invoiced for the catch-up fee. Analyzing Phase E cost projections in light of instrument team funding requests. Beginning effort to expand instrument science reporting in monthly status reports to the program office.
