The USA's efforts 'to expand human presence and activity beyond Earth orbit into the solar system' was given renewed emphasis in January 1988, when the Presidential Directive on National Space Policy was signed into effect. The expansion of human presence into the solar system has particular significance in that it defines long-range goals for NASA's future missions. To embark and achieve such ambitious ventures is a significant undertaking, particularly when compared with past space activities. The author discusses mission scenarios for human expeditions to Phobos and Mars, and for a Lunar Observatory. Power system requirements are briefly discussed
