Venus and Earth are almost identical twins. However one died and the other lived. That's interesting! Also it is widely believed that the eventual mode of death for the Earth will be a runaway green house effect due to an increase in Solar luminosity. Venus today is what the Earth will be like many millions of years in the future. That makes Venus even more interesting.

I firmly believe that there has never been life on Mars. However I suspect that life started on Venus about the same time it started on Earth. Who knows? Maybe we're descended from Venusian life, i.e. a meteor got blown off of Venus with a microbe on it that seeded the Earth. The name "Venus" may offer an ironic clue, i.e. Venus = Goddess of Sex. Maybe Venus inseminated the Earth.

Venus is worthy of exploration.
