Is 2019 the year we can get excited about space again? In the last few days, NASA's New Horizons probe followed Voyager out of the solar system, snapping Ultima Thule as it went, and China's Chang'e-4 unmanned craft landed on the far side of the moon. Neither the US nor USSR managed that. And of course July will be the 50th anniversary of the first moon landing. I know it's expensive and even former astronauts say it's stupid to try to send men to Mars, but I'm all for it. Why? Because it's there.
