Potential of Commercial Human Spaceflight

International Review of Aerospace Engineering (IREASE), 2017
The Space Race between the Soviet Union and the United States back in 1960s had propelled vast development of space technology. Although it was still nascent during that time, space technology had spurred the launch of the first human to outer space and eventually the first human to step on the Moon.

Venous Thromboembolism in Exploration Class Human Spaceflight.

Aerospace Medicine and Human Performance
INTRODUCTION: A recent finding of a deep venous thrombosis during spaceflight has prompted the need to clarify mechanisms and risks of venous thromboembolism (VTE). In turn, mitigation countermeasures, diagnostic modalities, and treatment options must be

How spaceflight challenges human cardiovascular health.

European Journal of Preventive Cardiology, 2022
The harsh environmental conditions in space, particularly weightlessness and radiation exposure, can negatively affect cardiovascular function and structure. In the future, preventive cardiology will be crucial in enabling safe space travel.

The future of human spaceflight

Acta Astronautica, 2001
After the Apollo Moon program, the international space station represents a further milestone of humankind in space, International follow-on programs like a manned return to the Moon and a first manned Mars Mission can be considered as the next logical step. More and more attention is also paid to the topic of future space tourism in Earth orbit, which

Is Human Spaceflight Now Obsolete?

Science, 2004
During the past year, there have been painstaking, and painful, investigations of the tragic loss of the space shuttle Columbia and its seven crew members. Congressional committees are now scrutinizing the competence of the investigators and reviewing perceived managerial and budgetary shortcomings of NASA.

A Plea for Further Human Spaceflight [PDF]

Science, 2004
James Van Allen (“Is human spaceflight now obsolete?,” Letters, 7 May, p. [822][1]) asks the proponents of human spaceflight not to “obfuscate the issues with false analogies to Christopher Columbus” or other explorers of similar caliber.

History of human spaceflight

2013
Over a period of about two centuries humans learned how to travel farther and farther from the surface of the Earth. However, we still have limited experience of flight in space. Progress was fast during the Cold War, when the competitive spirit between the United States and the Soviet Union drove both nations’ space engineers to work towards goals of ...

Seeking justifications for human spaceflight

Space Policy, 1994
Abstract Traditionally cited benefits such as scientific and economic progress or political advantages have been widely recognized as insufficient to justify ongoing and future human spaceflight programmes in today's prevailing geopolitical and socioeconomic environment.
