How rigorously is conjunction analysis (finding out the chances of hitting an asteroid or another known object) conducted for missions beyond Earth orbit?
Due to larger computational resources available has there been (in recent years or decades) a corresponding increase in attention devoted to ensuring a deep space probe won't hit another body accidentally? I know the space is VAST, but so is human complacency.
Are there any fixed rules that are obeyed by mission planners to avoid conjuctions?
