Coalition Formation for Sustainable Blockchain Governance: Insights From the Hedera Case

Information Systems Journal, Volume 36, Issue 4, Page 485-499, July 2026.
ABSTRACT Sustainable governance is essential for blockchain networks to achieve widespread adoption and deliver long‐term business value. Prior blockchain initiatives indicate that inadequate governance structures often lead to limited adoption or eventual project failure, underscoring the importance of decentralised governance for building resilient ...

A Novel Ice Cloud Optical Property Model for Passive and Active Remote Sensing Applications

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract A new broad‐spectrum ice cloud optical property model, namely the Passive‐Active Remote Sensing Consistent (PARSC) model, is developed to achieve consistency between passive and active sensor‐based ocean‐occurring ice cloud property retrievals.

Upper Atmosphere Research Satellite (UARS) onboard attitude determination using a Kalman filter

, 1993
The Upper Atmospheric Research Satellite (UARS) requires a highly accurate knowledge of its attitude to accomplish its mission. Propagation of the attitude state using gyro measurements is not sufficient to meet the accuracy requirements, and must be ...

Observing the Earth's Plasmasphere and Ionosphere From the Lunar Surface

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present the analysis of the first lunar‐based observational characterization of the Earth's plasmasphere and ionosphere using Global Navigation Satellite Systems signals tracked from the lunar surface by the Lunar GNSS Receiver Experiment (LuGRE). The Earth‐Moon geometry enables limb sounding of the plasmasphere at altitudes exceeding 3,000

Nitrate Photolysis in the Upper Boundary Layer as a Daytime Missing Source of HONO: Revealed by In Situ Airship Measurements and Modeling

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The missing source of nitrous acid (HONO) is a key uncertainty in understanding atmospheric chemistry in the troposphere. Particulate nitrate photolysis has been proposed as a potential source of daytime HONO, but its contribution remains poorly constrained, with even less attention paid to the impact of nitrate aloft. Here, we investigate the

Low Abundances of Ultramafic Components in the Chang'e‐6 Landing Site Basalt and Ejecta Material

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The South Pole‐Aitken (SPA) Basin, the Moon's largest impact structure, holds key insights into lunar evolution, prompting the Chang'e‐6 mission to return first samples for ground‐truth verification. Analysis of over 6,000 grains from the Chang'e‐6 soil returned from the SPA Basin reveals a composition dominated by clinopyroxene (26.5–32.9 vol.

Aerobraking Navigation, Guidance and Control: A Comparison of State Variables Performance in Propagation

, 2018
The amount of propellant required to perform deep-space maneuvers usually consists of a large percentage of the total spacecraft mass. In the early '90s, a new technique was experimented at the end of the Magellan mission, which employed the atmosphere ...

Earthward Propagated Auroral Kilometric Radiation: Observations From Polar

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Auroral Kilometric Radiation (AKR), the strongest natural radio emission from Earth's magnetosphere, has been primarily observed in space. It is generally understood to propagate anti‐Earthward and be detected at large radial distances, while Earthward‐directed waves are thought to be blocked by the ionosphere. Surprisingly, AKR‐like emissions
