Excerpts from a news article from ABCnews.com. The president is set to announce next week that he wants to send astronauts back to the moon around the year 2013, and to make a flyby of Mars by around 2020, sources say. To help pay for the program, the sources say the Space Shuttles would be retired as soon as they have finished building the International Space Station. The White House would also ask Congress to increase NASA's budget by $800 million next year, and keep increasing it by five percent for several years after that. Currently, NASA's budget is about $15 billion a year. Astronauts last walked on the moon in 1972. This time, it is believed the president favors a permanent station. A new multipurpose ship, called a "Crew Exploration Vehicle," would be built as NASA's future workhorse. It would consist of different components that could be combined as necessary for different missions, whether they are to Earth orbit, the lunar surface, or beyond. ------------- A permanent space station on the moon beginning in 10 years?
