Thanks to a crash landing by an Israeli lunar experiment, the nearest world to our own has a small colony of living things alien to its environment. Well, sort of, since the tardigrades, the extraordinarily hearty creatures on board, are in a state of suspended animation and won't be doing much of anything for millions of years if left alone. But this incident does raise a few red flags we need to address before we keep exploring space, especially with privately built and financed experiments, and brings up some very bizarre questions about the origin of life on Earth and other inhabited worlds we have to take seriously.
