Remote automated multi-generational growth and observation of an animal in low Earth orbit [PDF]

open access: yes, 2012
The ultimate survival of humanity is dependent upon colonization of other planetary bodies. Key challenges to such habitation are (patho)physiologic changes induced by known, and unknown, factors associated with long-duration and distance space ...

Intergalactic spaceflight: an uncommon way to relativistic kinematics and dynamics [PDF]

open access: yesarXiv, 2006
In the Special Theory of Relativity space and time intervals are different in different frames of reference. As a consequence, the quantity 'velocity' of classical mechanics splits into different quantities in Special Relativity, coordinate velocity, proper velocity and rapidity.
