Are there any dark horses that could beat China, Russia, the US and UK to it?

Unlikely, perhaps, but there seem to be more space agencies around than when I was a kid.

I guess Putin forgot about the robot that NASA landed there awhile back....

As a said note to Eric Ladd: I've seen Iron Sky, it was a fun B movie.

There isn't a Hohmann transfer window in 2019. There's one this year, and one (as usual, 2.1 years later) in 2020.

That pretty much leaves an opposition-class transit which has much higher deltaV (change in velocity) requirements on both ends. For the same rocket, that forces you to use a much smaller delivered payload to compensate.

I miss the old days, when flying to another planet was pretty much the same as driving to another town!

We could be here because of microbes from Mars.
