I thought it was time to start a separate thread on this mission, launching soon
some good medium-resolution images of the spacecraft are available on JAXA digital archives http://jda.jaxa.jp/jda/p3_e.php?time=N&...mp;mission=4066 |

a new pdf release by JAXA http://www.jaxa.jp/press/2011/10/20111026_sac_akatsuki.pdf above for ease of reference page 7 6.Summary of this report 1.Akatsuki's current health and operational plan from now – All insturments on board are healthy and the satellite is circulating around the Sun – From the in-orbit firing of the OME conducted in September this year (2011) we judged that OME will not be able to produce an effective propulsion required for further orbit controls and that any further orbit control will have to be achieved by the RCS engines – Dumping of unrequired oxidiser was conducted in October this year in order to reduce the satellite mass and this operation was confirmed to be a success from telemetry data, all aprts of the satellite not exceeding the allowed limit in temp. 2. Nearest sun approach orbit control – Orbit control by RCS engines is planned for November this year as the satellite makes a nearest approach to the Sun. – We investigated the risks involved in the orbit control by RCS and it has been confirmed that there is a good scope for safe operation. – Orbit control will be divided into three parts, each taking place on 1, 10, and 21 November and depending on our further consideration and the outcome of controls the orbit control plan may change. end of page 7 and end of this particular report P |
