Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

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-

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

MAVEN Observations of Metallic Fe+ Distributions in the Martian Ionosphere

open access: yesGeophysical Research Letters, Volume 52, Issue 14, 28 July 2025.
Abstract Metallic ions deposited in planetary atmospheres via meteoroid ablation are an invaluable tool for understanding electric fields, atmospheric winds, and minor ion transport. At Mars, metallic ion distributions are poorly understood. We analyze MAVEN/NGIMS Fe+ ${\mathrm{F}\mathrm{e}}^{+}$ distributions in the Martian ionosphere over the period ...

Towards the Final Frontier: Using Strategic Communication Activities to Engage the Latent Public as a Key Stakeholder in a Corporate Mission [PDF]

open access: yes, 2018
Private corporations that do not normally interact with, nor regularly communicate with, the public often do not perceive the public as a relevant or active stakeholder.

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.

The Impact of OMNI Data Accuracy on Thermospheric Neutral Density Simulations at Grid Cell Resolutions

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract As physics‐based global magnetosphere‐ionosphere‐thermosphere models enter operations for space weather forecasting, it is imperative that the sources of uncertainty in model outputs are thoroughly investigated. Global magnetosphere models rely on a set of input solar wind conditions to drive the model; such inputs are often propagated from ...

Microalgae: A Solution for Food Security and Multiplanetary Farming

open access: yesFood Frontiers, Volume 6, Issue 3, Page 1242-1251, May 2025.
ABSTRACT Human civilization is threatened by food insecurity and habitat loss owing to the cumulative effects of anthropogenic and natural factors. Thus, increasing food production while using fewer resources and exploring the potential of interstellar migration is essential.
