JAXA wants to continue with Hayabusa 2. However there is/was a huge fight about the budget. Main problem was the budget for the launch vehicle. 2 months ago or so there was a report which said, that JAXA had to find another launch vehicle or the project gets cancelled. Now the Italian space agency played saviour and overed the VEGA. So finally we might see another Hayabusa in 2011.
It was mentioned here: http://www.jspec.jaxa.jp/080110Final_IPEWG-ProgramBook.pdf |

You can now submit your name on the Japanese version of JAXA's Hayabusa 2 page:

I have checked with JAXA HP in English, but I could not find immediately if what follows is actually carried there. So, just in case, what follows is from Nihon Keizai Shimbun dated 23 April.
"JAXA are inviting 2 piggy-back interplanetary space probes: JAXA announced on 23 April that they will invite 2 piggy-backs to be launched with Hayabusa 2 on their H2A rocket. Invitation period is by the end of May and selection will be made at the end of June. 2 space probes of each less than 50 kg are invited. Hayabusa 2 itself will weigh 600 kg." This makes me think and wonder as follows. 1. Can anybody make proposals so quickly? 2. This must be just powdering operation and the infomation has been circulating within intimate circles, both domestic and intrernational, for a long time. P |

" 2 piggy-backs to be launched with Hayabusa 2 "
I thought the ATOM (Mars aero-capture mission ) would be one of those missions? I read something about it in 2012. |

according to this presentation (undated but named "fall 2012")
QUOTE Mars aero-capture mission ATOM -> Delayed Phase-A study continues, but launch with Hayabusa-2 became difficult. |

1. Can anybody make proposals so quickly? I honestly don't think so, just a proposal can take up to a year to get a heads up. Then they would have to build it. Even if some agency or university were sitting on one suitable unlaunched craft/probe, they would have to practically carry it out the door directly for intergation and testing. So it sound like a nice offer, though one without actual candidates, now that delays have created a vacant spot - perhaps even two. |

Is it also too late to use those 50 kilos on Hayabusa 2 itself, somehow? Or is this offer specifically for other craft on the same launcher? I mean it would be a waste to just let an opportunity like this go.

Sure, but it would be a risk to rush a development & integration effort with too little time for testing before the launch date. Let's see what they do.

Aviation Week and Space Technology reports that Japan will be cutting back on its space plans and, "But former high-priority goals to promote environmental monitoring, human space activities and putting robots on the Moon are now much lower priorities and will have to fight for funding." I don't know how this will affect Mars plans. Hayabusa-type missions are apparently still planned.

Hayabusa 2 will be accompanied in solar orbit by two microspacecraft, PROCYON and Artsat 2 and possibly also by Shin'en 2.
The most interesting of the bunch is PROCYON which, among other things, will demonstrate imaging techniques during at least one but possibly up to three close flybys of small NEOs a presentation of the mission and spacecraft is available here |

The most interesting of the bunch is PROCYON which, among other things, will demonstrate imaging techniques during at least one but possibly up to three close flybys of small NEOs a presentation of the mission and spacecraft is available here Re above I have just translated this article and the first few pages (up to page 5) are as follows. The rest can be uploaded within the next week, I think. (P) Contents of Presentation • Significance and possibility of hyper minitualisation in deep space exploration * Reference in Space Science and Probe Roadmap • What is hyper minitualisation? • Status of hyper minitualisation space probe industry • Mission possibilities in hyper minitualised deep space probes * PROCYON- 50kg class hyper minitualised deep space probe • Mission outline • Probe system outline • Development • Development schedule P-2 (continue from page 2) Significance in minitualisation and hyper minitualisation What follows are some of the remarks made in the Space Science Probe Roadmap. Here, Importance of minitualisation of satelliets and space probes is recognised. • with a view to realising low cost and high frequency space science missions using improved Epsilon rockets we should aim at minitualisation and improvements of satellites and space probes • improved Epsilon rockets should be able to send out small solar system probes more frequently... • future visions of space probes and satellite systems...through innovation, minitualisation, and weight reduction in probe architecture we should aim at more advanced and flexible missions P-3 •Objectives in minitualisation include frequent missions under budgetary and costing constraints. However, it does not mean "minitualisation=conpromise in sceince results (should not) ---> what should then we be doing? Hyper minitualisation=Innovation (diagram header) Horizontal axis: system scale and number of functions etc. Vertical axis: costs, weight, development length etc. horizontal dotted lines in red: limit of costs and weights etc. 3 character sets in square from top to bottom are: No innovation Innovation speed: low Innovation speed: high (Annotation along the dotted lines in black from LL to UR) more functional! more advanced missions! more... more... P-4 Annotation along the dotted lines in red from LL to UR innovation in minitualisation (such as introductionof highly advanced techniques) etc.) more advanced missions made possible! P-5 |
