Mars is 250 million miles from Earth at the farthest point in the planets' orbits. Sheer distance makes unpredictable weather, unexpected illness and even homesickness potentially deadly problems. Residents of the future Mars base won't be able to count on a rescue mission.
For other Devil's Trumpet, see Datura (disambiguation). Datura is a genus of nine species of poisonous vespertine flowering plants belonging to the family Solanaceae. They are commonly known as daturas, but also known as devil's trumpets, not to be confused with angel's trumpets, its closely related genus Brugmansia.
Some South American plants formerly thought of as Datura are now treated as belonging to the distinct genus Brugmansia (Brugmansia differs from Datura in that it is woody, making shrubs or small trees, and it has pendulous flowers, rather than erect ones).atura belongs to the classic witches' weeds, along with deadly nightshade, henbane, and mandrake. Most parts of the plants are toxic, and datura has a long history of use for causing delirious states and death. It was well known as an essential ingredient of potions and witches' brews.
