Pioneer 11, Voyager 1 and 2, and Cassini-Huygens (which is presently orbiting Saturn.)
NO!!!! However, there have been named missions to the outer planets, notably 'Voyager'.
Although several spacecrafts have been sent to Venus, no alien spacecrafts have been discovered on its surface.
Mars has been viewed, mapped, probed and driven over by a selection of man-made spacecraft and probes since the early 1970's, but man himself has not yet ventured that far into space - except by cameras sending back imagery.
Based on the scriptures Jesus is viewed as healing the sick, working miracles, raise the dead, and many other things but they were all spiritual, his primary focus. The other planets can be viewed as worldy, and that might have been the reason.
At current we have sent, or are sending, probes to all of the planets in our solar system. The probe Voyager has visited several planets, including Jupiter and Neptune, while Cassini is currently in orbit around Saturn.
yes, voyager 1, voyager 2, Cassini Huygens
Yes. We have landed multiple probes and rovers on Mars.
mariner 10 and MESSENGER
Most famously, it was voyager 1 and 2 that explored these outer gas planets and have given us so much information. Other probes have been sent to these gas giants, but these are the the probes that visited all four gas giants between them.
