Cost in Space -----the long-term exploration plan Crew: youngerh maniclone JC
A new political check? WASHINGTON, Jan. 14 --President Bush proposed on Wednesday to develop a new spacecraft to carry Americans back to the moon as early as 2015, and to establish a long-term base there as an eventual springboard to Mars and beyond.
Nope, it’s for real… reasons: 1. To release the over population pressure. 2. To turn people’s focus from low Earth orbit to new journeys to the worlds beyond our own.
Why choose the moon? The closest satellite around Earth— the easiest way to immigration. To take advantage of lunar system— has one-sixth the gravitational field of Earth, so spacecraft could be launched from there to Mars with less fuel.
Then, why choose Mars? Has similar climatic condition as Earth. Has oxygen and steam in the air. Has simple organism in the aerolite.
Bush’s timetable 2004-2008: $1 billion in new spending over five years, and shift $11 billion in federal money from other NASA programs over that same time frame to make way for the program. 2008-2015: "Robotic missions will serve as trailblazers” 2015-2020: The Crew Exploration Vehicle—to transport men to the moon.
The background “The old Bush”—in 1989, he proposed putting astronauts on Mars, but did not mention a moon base. Because that plan was projected at $400 billion to $500 billion, a price tag that discouraged Congress. The project was never started.
Responses Bush said he hoped other countries would contribute to the outer-space cause. NASA's O'Keefe said he had discussed the initiative with his counterparts from other space agencies.
Critics have suggested that the younger Bush’s initiative would likewise be too expensive for taxpayer Robert Greenstein, exclusive director of the liberal center on Budget and Policy Priorities, he said. House Democratic Leader Nancy Pelosi, said Bush's plan would face strong congressional scrutiny.
Sen. Bill Nelson, questioned whether $1 billion in extra funding would be enough to do what Bush ahd in mind. The initiative was praised by Bush's Republican colleagues.
Safety in space adventure? Spare no efforts on studying health effects of spaceflight.
