The Perseverance rover, which is on Mars, internally holds a piece of a Mars meteorite found in Antarctica, which is used to double-check the spectrograph’s readings. That rock is thus the first object to make the round trip journey from Mars to Earth and back.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
