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.

FINE TIME STRUCTURE OF LIGHTNINGS ON SATURN

open access: yesRadio 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/

The Cushion Region and Dayside Magnetodisc Structure at Saturn

open access: yesGeophysical Research Letters, 2021
A sustained quasi‐dipolar magnetic field between the current sheet outer edge and the magnetopause, known as a cushion region, has previously been observed at Jupiter, but not yet at Saturn.

A Domain‐Independent, Extensible Framework for Generators of Training Game Activities on Declarative Knowledge

open access: yesJournal of Computer Assisted Learning, Volume 41, Issue 4, August 2025.
ABSTRACT Background Training the memorization of declarative knowledge requires the repetitive presentation of various forms of factual questions to learners. Educational games designed for this purpose should offer activities that are both tailored to individual learners and varied to prevent boredom.

Investigation of strength properties of freshwater ice

open access: yesEPJ Web of Conferences, 2015
A study of the strength and deformation properties of freshwater ice under compression, tension and shear in a wide range of strain rates (10−4 − 3 ⋅ 103 s−1) and temperatures of − 5∘ C, − 20∘ C, − 40∘ C and − 60∘ C was performed.

A Past Episode of Rapid Tidal Evolution of Enceladus?

open access: yesThe Planetary Science Journal, 2023
Saturn possesses a dynamically rich system containing numerous moons and impressive rings. Whether the rings of Saturn are much younger than the planet itself has been a long-standing open question; more recently a young age has been proposed for some ...

Unstable anthocyanin pigmentation in Streptocarpus sect. Saintpaulia (African violet) is due to transcriptional selectivity of a single MYB gene

open access: yesNew Phytologist, Volume 247, Issue 3, Page 1426-1444, August 2025.
Summary Saintpaulia (African violet) pigmentation is notoriously unstable and sometimes forms white stripes, particularly following passage through tissue culture. White‐striped petals were thought to be due to periclinal chimeras, but we confirmed that white stripes result from epigenetic regulation rather than periclinal chimeras based on the flower ...
