Austerity is the name of the game in many western countries following the global economic crisis of 2008 but it has never been about a lack of money. All it does is widen the rich poor divide and help that elusive 1% get richer.
If it had been about the money would BBC News be reporting Saturday "This week, the European Space Agency (Esa) released another 70 million euros to advance the rover mission towards its date with a Proton launch rocket in May 2018".
Note, another 70 million euros - how many more monetary advances have been made? Money could of course dry up which could in turn scupper the project. Imagine then the amount of money that will have been spent for nothing.
In 2012 the USA pulled out of the project. Russia stepped in to plug the monetary gap but with so many sanctions ongoing against Russia will they now also pull out?
The European space agency has decisions to make about the type of undercarriage its ExoMars Rover; Lavochkin is still working through the potential configurations for the ExoMars landing mechanism but that is surely the least of their worries?
