Effects of parabolic flight and spaceflight on the endocannabinoid system in humans [PDF]

open access: yes, 2012
The endocannabinoid system (ECS) plays an important role in the regulation of physiological functions, from stress and memory regulation to vegetative control and immunity.

Mars Missions Failure Report Assortment: Review and Conspectus [PDF]

open access: yes, 2019
Mars has been successfully explored by various space firms. Globally, 44 mission attempts were made, lamentably 26 encountered setbacks. There have been instances where a trivial error in the progressive accomplishment of spaceflight sequence might prompt in an extreme loss.

The Astronomical, Astrobiological and Planetary Science Case for Interstellar Spaceflight [PDF]

open access: yesJournal of the British Interplanetary Society, 62, 415-421, (2009), 2010
A review is presented of the scientific benefits of rapid (v >= 0.1c) interstellar spaceflight. Significant benefits are identified in the fields of interstellar medium studies, stellar astrophysics, planetary science and astrobiology. In the latter three areas the benefits would be considerably enhanced if the interstellar vehicle is able to ...

Targeted Nuclear Spallation from Moderator Block Design for a Ground-Based Space Radiation Analog [PDF]

open access: yesarXiv, 2017
Current radiobiology studies on the effects of galactic cosmic ray radiation utilize mono-energetic beams, where the projected dose for an exploration mission is given using highly-acute exposures. This methodology does not replicate the multi-ion species and energies found in the space radiation environment, nor does it reflect the low dose-rate found

Interplanetary Laser Tri-lateration Network: simulation with INPOP planetary ephemerides [PDF]

open access: yesarXiv, 2023
This study is done in the context of the project titled Interplanetary Laser Tri-lateration Network (ILTN) proposed by \cite{2018P&SS..153..127S} and investigated more in details by \cite{2022P&SS..21405415B} and \cite{2022P&SS..21505423B}. The original idea was to propose interplanetary measurements (in this case between Venus, Mars and the earth) as ...

Towards an integrated scientific and social case for human space exploration [PDF]

open access: yes, 2004
I will argue that an ambitious programme of human space exploration, involving a return to the Moon, and eventually human missions to Mars, will add greatly to human knowledge. Gathering such knowledge is the primary aim of science, but science's compart-

Galactic Accessibility: An Introduction to Interplanetary Human Rights Law Through Crip Legal Theory [PDF]

open access: yes, 2022
The possibilities within the realm of outer space and future space exploration have always been limitless. There has been renewed interest in space over the last decade, largely fueled by the private commercial space sector.

An Orbitrap-based laser desorption/ablation mass spectrometer designed for spaceflight [PDF]

open access: yes, 2018
RATIONALE: The investigation of cryogenic planetary environments as potential harbors for extant life and/or contemporary sites of organic synthesis represents an emerging focal point in planetary exploration. Next generation instruments need to be capable of unambiguously determining elemental and/or molecular stoichiometry via highly accurate mass ...
