"Search for life on Mars is frozen", Interesting article by Colin Pillinger. Options

[sci44]

The Telegraph has this interesting new piece written by Colin Pillinger.
(I am posting to Beagle-2 thread, although it also covers Phoenix, ExoMars and Mars exploration in general.) You may remember this piece of his in the Guardian back in May.
It was always a great shame that no one can find the relatively small sum needed to send another Beagle-3 - it would be a great way to provide a continuing back-up Mars surface mission should (god forbid) there is a hitch with MSL. How practical would it be to add to a planned mission like MAVEN? How much more, in terms of an attatched delivery craft/system, etc, would be needed if it was sent on one of the new cheaper launchers, like Falcon-1/9? Beagle 2 weighed 69kg at launch and Falcon-1 delivers 670kg to LEO - which I would doubt is enough for a cruise stage plus fuel..
