Something very interesting I saw at NASA Spaceflight: http://forum.nasaspaceflight.com/index.php...7343#msg1307343
QUOTE "Nov. 22, 2015 plan is cancelled. It turned out this orbit is decayed too early. New plan is waiting for manager's approval." I'm not sure exactly what this means, possibly a different Venus orbit insertion date and/or a different Venus orbit. |

The manager must have great control over physics and gravity if his approval is required. I, too, would seek his favor.
Bummer. They're close enough to the sun to no doubt have a gagillion non-Newtonian effects |

There appeared a short article in today's Yomiuri newspaper here saying that
JAXA will try Akatsuki re-insertion into an elliptical orbit in early December this year. Fuel left is just enough to try once and once only. P |

Spaceflight Now has an article on the next try.
Don't know if there's anything new there but it seems like a good summary for those (like me) who haven't been fully paying attention. |

if I understand this JAXA release correctlym Akatsuki is to fire its thrusters three times from July 17th to correct its trajectory and test the thrusters in view of the orbit insertion

The last course correction in November 2011 was also split into three parts with several days between them to track the probe and refine the next correction.

With the distinct lack of any near-future action on any other Venus spacecraft, I really hope JAXA can pull this save off and recover at least a portion of the original mission plan. They have some form in this 'miracle' area after all!
