All activities (except for MSA power cycle on 8 August) will be performed by MPO mission timeline.
We don't request to monitor/check the telemetry data in real time, but anyway we will use the following Zoom link during the passes between 8-11 Autust.
If you have any news or points to be discussed with JAXA system members, please join it.

JAXA plans to publish a web article for public/media within 2 weeks after Venus flyby.
Any quick results which can be open are highly appreciated.


I hope successful Venus flyby and looking forward to seeing interesting data!
Fingers crossed!!

Best regards,
