Dear Amy: When will humans be able to go to Mars? — John, St. Louis, Mo.
Dear John: Mars is a long way from Earth, with a distance that varies from 36 million miles, the closest point to Earth in its orbit, to over 250 million miles. Despite the extreme distance and challenges, sending astronauts to Mars is one of NASA’s long-term goals. NASA’s first step in preparing to visit Mars is sending exploration crews from the International Space Station to closer destinations, such as the moon and near-Earth asteroids. These shorter missions will allow astronauts to test new technologies and prepare for longer journeys.
