Reply to comment by IsraelZulu in A spaceflight disaster was narrowly avoided in 1972. A series of intense solar flares exploded in August, just months before the launch of Apollo 17. Any astronauts on the moon at that time would have died from radiation. As NASA's new lunar missions progress, the threat of radiation still looms. by EricFromOuterSpace

Even more difficult when it comes to Mars because of the long transit times. We can predict solar activity reasonably well in the short term and the Apollo missions were short enough that we could have just delayed a mission if conditions on the sun looked dicey.
