Neither do I follow mars missions in general (I maybe should) nor the betting markets for it. But I know that some austrian bookie is offering Mars-bets since years already. They had some fun bets like "What will happen first ? England winning the FIFA World Cup or humans landing on Mars." These bets are gone now as it seems, but there are different ones now and it looks like they don't trust in any of your mentioned missions being successful:

Couldn't find any markets anywhere else, but I am not able to access some US bookies, like Bovada, who should have markets as well. Maybe you can check and post here then.
