Here are some ideas I had after reading that issue of Nature:
Idea 1 of 3:
Nature 459 21 may 2009 308-309
Possibly an angle for the cyclo-olefin encapsulation/UVC sterilisation idea (CO/UVC) I pitched earlier for balloon canopies.
The article describes the concerns of Plan Protect people (Catharine Conley is interviewed) as to how existing spacecraft (eg Mars landers) are inadequately sterilised.
NASA is thinking of adopting hydrogen peroxide sterilisation because, for instance, autoclaving is too difficult for entire spaceprobes.
I think my CO/UVC is more practical since it allows by steady sterilisation over a period of time, so it is much less harsh than any chemical treatment.
Spacecraft could be sterilised in cruise flight by fixed UVC sources covering every nook and cranny.
A CO shroud, illuminated from within, also could be useful since it allows encapsulation of extra clean components (eg arms, scoops etc)
Could we use HAB as a near-space demonstrator of this?
Is there money to be had from people like Caroline?
Idea 2 of 3:
Public funded small scale science
Nature 459 21 may 09 p305
Allows you to fund small projects from public donations - you pitch your project on the website.
Might be useful for some small scale funding (I.e a particular HAB flight perhaps)
Idea 3 of 3:
Nature 459 21 may 09 316-319
Mike Russell origin of life article
Not so much an idea - interested to know what you think of Mike's ideas. I heard a lecture by him some years back and was transfixed.
