The search for the ultimate exercise countermeasure to preserve crew health and ensure mission success in long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract The current understanding of crew health maintenance is founded upon decades of physiological research conducted in terrestrial spaceflight analogues and in low Earth orbit, particularly on the International Space Station. However, as we progress towards the Lunar Gateway and interplanetary missions, it is imperative that the tools employed to

The Density Distribution of Compressively Forced, Supersonic Turbulence Depends on the Driving Correlation Time

The Astrophysical Journal
Supersonic turbulence plays a critical role in shaping astrophysical systems, from molecular clouds to the circumgalactic medium. Key properties of this turbulence include the Mach number, driving scale, and nature of the driving mechanism, which can be ...

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

Experimental 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 ...

An Improved Fit to the Density Fluctuations in Supersonic Isothermal Turbulence

The Astrophysical Journal
The density distribution of supersonic isothermal turbulence plays a critical role in many astrophysical systems. It is commonly approximated by a log-normal distribution with a variance of ${\sigma }_{s,{\rm{V}}}^{2}\approx \mathrm{ln}(1+{b}^{2}{M}_ ...

MHD waves at the pre-front of interplanetary shocks on September 6 and 7, 2017

Solar-Terrestrial Physics
We analyze strong space weather disturbances during first ten days of September 2017, using the geomagnetic Dst index, parameters of normals to interplanetary shock fronts, direct measurements of interplanetary magnetic field, solar wind, and cosmic ray ...

Universal Time Influence on Stormtime Magnetosphere Ionosphere Coupling

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract The offset between Earth's magnetic and rotational axes introduces a diurnal dependence in the high‐latitude EUV exposure of the northern hemisphere (NH) and southern hemisphere (SH). This variation raises the question: Does the Universal Time (UT) of geomagnetic storm onset impact its geospace consequences?

FINE TIME STRUCTURE OF LIGHTNINGS ON SATURN

Radio Physics and Radio Astronomy, 2014
The results are reported of the very first study of Saturn lightning fine time structure with superfine time resolution (within hundreds to units of nanoseconds). It is ascertained that the lightning time structure has two intrinsic scales: from hundreds/

Peculiarities of the Heliospheric State and the Solar-Wind/Magnetosphere Coupling in the Era of Weakened Solar Activity

Universe, 2022
Based on the data of the solar wind (SW) measurements of the OMNI database for the period 1976–2019, we investigate the behavior of SW types, as well as plasma and interplanetary magnetic field (IMF) parameters, for 21–24 solar cycles (SCs). Our analysis

Smart Waste, Smarter World: Exploring Waste Types, Trends, and Tech‐Driven Valorization Through Artificial Intelligence, Internet of Things, and Blockchain

Sustainable Development, Volume 34, Issue S2, Page 132-153, March 2026.
ABSTRACT Global municipal solid waste generation is projected to exceed 3.8 billion tonnes annually by 2050. This makes the need for smart, inclusive, and scalable waste valorization systems more urgent than ever. This review critically explores the shift from conventional waste management to intelligent, technology‐driven solutions aligned with ...

Near-earth solar wind flows and related geomagnetic activity during more than four solar cycles (1963–2011)

Journal of Space Weather and Space Climate, 2012
In past studies, we classified the near-Earth solar wind into three basic flow types based on inspection of solar wind plasma and magnetic field parameters in the OMNI database and additional data (e.g., geomagnetic indices, energetic particle, and ...
