Cluster as current sheet surveyor in the magnetotail [PDF]
Annales Geophysicae, 2013 A novel analysis technique is presented to estimate the current sheet thickness unambiguously and directly, without associating time series data with spatial structure.

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges
Experimental Physiology, EarlyView.Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Single-event upsets in the Cluster and Double Star Digital Wave Processor instruments [PDF]
, 2014 Radiation-induced upsets are an important issue for electronic circuits operating in space. Upsets due to solar protons, trapped protons, and galactic cosmic rays are frequently observed.

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 ...

Solar Wind Electric Fields in the Ion Cyclotron Frequency Range
, 2006 Measurements of fluctuations of electric fields in the frequency range from a fraction of one Hz to 12.5 Hz are presented, and corrected for the Lorentz transformation of magnetic fluctuations to give the electric fields in the plasma frame. The electric

Reconstructing the Geometry of a Hot Flow Anomaly With Bounding Jets in Magnetosheath
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract When interplanetary magnetic field discontinuities interact with planetary bow shocks, hot flow anomalies (HFAs) form in the solar wind and can extend into the magnetosheath. Here we reconstruct the three‐dimensional geometry of an HFA bounded by two jet regions in the terrestrial magnetosheath.

Small-scale dipolarization fronts in the Earth′s magnetotail
Earth and Planetary Physics, 2019 Previous studies suggest that dipolarization fronts (DFs) are 1 to 3RE (RE is the earth radius) wide in the dawn-dusk direction. Recent kinetic simulations have found that DFs may break up into small-scale structures after they are produced by ...

Nanophotonics, Volume 15, Issue 3, 12 February 2026.Passive regulation of thermal management in space relies on engineered radiative coatings that can vary their emissivity with temperature. Here a smart and flexible solution is presented combining a W:VO2 metasurface with a low‐emissivity solar reflector. This highly durable first‐surface coating survives space qualification tests and offers attractive
