Mission: Hayabusa 2 Options

[spdf]

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.

Seems to me like the goal is both replicating Deep Impact but on an inert body instead of out-gassing comet. This includes staying in the vicinity rather than just a flyby, so as to measure the velocity change easier.

I realise that I have been putting all this very badly indeed.

First of all, there is no mistake in my translation about "explosion". They did say "explosion" in mid space.

My question/comment is this.

Mid space explosion cannot possibly direct a collidinng mass into the right direction. Neither will it be able to give it a sufficient kinetic energy to dig a hole in the asteroid.

So, what kind of explosion are they talking about? Perhaps, the collidinng mass has an explosive charge to detonate even if incorrectly pointed (as long as it does get tothe asteroid surface?).
