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

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.

We present a numerical algorithm aimed at identifying ion diffusion regions (IDRs) in the geomagnetic tail, and test its applicability. We use 5 criteria applied in three stages.

Abstract Near‐earth orbits are becoming congested because of a rapid growth in the number of satellites and space debris, which presents a real threat to the sustainable use of space and the safety of the Earth. Despite space scientists and public policymakers having been actively seeking solutions for decades, solving the problem has been put off ...

➢ A one‐step selective laser reaction pyrolysis (SLRP) technique was developed to rapidly synthesize hafnium carbide (HfC) from liquid polymer precursors. ➢ XRD and TEM confirmed the nanocrystalline structure of the HfC. ➢ The SLRP‐based process achieved up to 54% ceramic yield, 18% higher than furnace‐based methods.

Scaling of the electron dissipation range of solar wind turbulence
Electron scale solar wind turbulence has attracted great interest in recent years. Clear evidences have been given from the Cluster data that turbulence is not fully dissipated near the proton scale but continues cascading down to the electron scales ...

Analysis of Microbial Diversity and Evidence of Contamination at a Mars Analogue Habitat
We assessed the potential of a crewed mission to Mars to microbially contaminate the surface by studying a terrestrial analogue facility, the Mars Desert Research Station. DNA sequencing of interior swabs and an external soil sample allowed us to characterise the microbiomes present.
