  The Space Review: Sagan's rationale for human spaceflight
The relationship between human spaceflight and the survival of the human species was explained by the spaceflight pioneers Konstantin Tsiolkovsky and Robert Goddard, and has since been expressed by Stephen Hawking, Carl Sagan, and many others.
In medieval times, some people kept a human skull in their home to remind themselves of mortality, and to view their priorities against the big picture of life and death.
Human spaceflight and the survival of the human species are ideal subjects for the screen.

  A&G Spaceflight Paper
In the future, powerful sociopolitical reasons for human space flight are likely to include the demands of the world economy for extraterrestrial raw materials, and the continuing need for high-profile international projects as aids in building a stable geopolitical environment here on Earth (Crawford 1995).
As the complex motivations for human space flight are not primarily scientific, it follows that they are not, and indeed cannot be, financed primarily from scientific budgets.
While recognizing that many of the driving forces behind human space flight are social and political, rather than narrowly scientific, it seems clear that science has been, and will continue to be, a major beneficiary of having people in space.

 Human spaceflight - Wikipedia, the free encyclopedia
Human spaceflight is spaceflight with a human crew and possibly passengers, which is in contrast to robotic space probes or remotely-controlled unmanned space missions.
The only destination of human spaceflight missions beyond Earth orbit has been the Moon, which is itself in Earth orbit.
Most of the time, the only humans in space are those aboard the International Space Station, whose crew of three spends up to six months at a time in low Earth orbit.

 Spaceflight Overview
Spaceflight is flight that occurs beyond the Earth's atmosphere using vehicles called spacecraft.
Human spaceflight quickly became the main aspect of competition in the Space Race, and the most expensive.
The most ambitious human spaceflight program, from both a technological and a financial standpoint, is the International Space Station, or ISS, now being developed by a consortium consisting of Russia, the United States, Europe, Japan, and others.

 Need for New Policy   (Site not responding. Last check: 2007-10-10)
The long term viability of human exploration of space requires that a new political covenant must be constructed between the technical community and the rest of society as represented by international political institutions.
Although human spaceflight can also be supported in terms of the massive problems facing humanity on the Earth in the next Century, they are of little interest to today's politicians.
Human spaceflight is particularly expensive, and only the United States and Russia have felt compelled to make that scale of societal investment.

 Human Spaceflight
The first set of challenges faced by humans entering into space are encountered during the acceleration and de-acceleration periods during lift-off and re-entry.
Before humans had been sent into space, many scientists made predictions about the effect microgravity might have on the human body, predictions which often were in contradiction with each other.
Humans in space must be protected from many hazards, from space radiation to the debilitating effects of microgravity responsible for progressive loss of bone mass.

 Space Science Pioneer Van Allen Questions Human Spaceflight
A leading space scientist has called to question the validity of human spaceflight, suggesting that sending astronauts outward from Earth is outdated, too costly, and the science returned is trivial.
The human spaceflight critic is no stranger to space -- in fact he’s a pioneer in the space science arena from the premier days of satellites orbiting Earth.
Supporters of human spaceflight “defy reality and struggle to recapture the level of public support that was induced temporarily by the Cold War,” van Allen charges.

 Space Policy Experts Discuss Goals for Human Spaceflight Program
Exploration as the Goal for Human Spaceflight: Many participants believed that the primary goal of the human spaceflight program should be exploration, in order to satisfy a basic human drive and to contribute to the acquisition of new knowledge.
Others commented that human explorers can take advantage of "unanticipated learning" opportunities for learning in a way that robots cannot, and humans can communicate to others what it is like to experience outer space.
For example, the goal of achieving long-term human exploration, it was noted, could provide "a very clear justification" for the configuration of, and research aboard, the space station, and the design of the next space transportation system.

Human spaceflight spans an epoch of more than forty years, 1961 to 2004, surely a long enough period to permit thoughtful assessment.
Nonetheless, advocates of human spaceflight defy reality and struggle to recapture the level of public support that was induced temporarily by the Cold War.

 Alternate Universe: Human Spaceflight Without NASA?
I had asked Dyson and other top scientists about the future of human spaceflight, on a day when worldwide media reports said President Bush might soon announce a major new human space initiative, to the Moon and perhaps Mars.
Human space flight has a bad reputation because "the pretence that the shuttle and the space station could do first-rate science has now collapsed," Dyson said.
The ultimate goal of any return to human spaceflight, in the minds of many scientists, would be a multi-billion dollar crewed mission to Mars like the one proposed by Robert Zubrin, who leads the Mars Society.
