Others are considering the ships that will carry human crews to Mars, the orbiting space station needed to launch them, the size and safety of the crews and the most practical routes through space. Though some formidable problems remain, many Soviet and U.S. experts see no insurmountable obstacles to landing humans on Mars early in the 21st century...
