A lot of Earth-built robots are hard at work on and orbiting the Red Planet. They've revealed a lot. The next generation of robot explorers, however, is apparently seriously delayed -- and it's an international problem.
The article that triggered this post deals mostly with a delay in a Russian-orchestrated mission to Phobos, but the last paragraph reminds us of other multi-year delays, in a next-gen NASA rover and of a European Space Agency probe.
Given the current economic climate, it's easy to imagine delayed missions getting delayed even further, or canceled altogether.
Space scientists are among the few constituencies somehow unworthy of new funding while governments dispense trillions. Perhaps anything from which we might actually learn is ineligible.
