Migrating and Nonmigrating Neutral Mass Density Tides From GRACE‐FO Observations for Solar Minimum Conditions

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study presents the migrating and nonmigrating thermospheric neutral mass density tides from the Gravity Recovery And Climate Experiment Follow‐On (GRACE‐FO) observations under solar minimum conditions (year 2020). The observed densities are first mapped to a reference altitude of 500 km using an empirical model (NRLMSIS 2.0) to remove the

Low Thrust Augmented Spacecraft Formation-Flying [PDF]

, 2015
Ballistic spacecraft formation-flying with zero thrust has great utility, but it is limited to a comparatively small set of relative trajectories.

Response of Topside Ionospheric Electron Density During Solar Flares Using 2014–2024 Swarm Satellite Measurements

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract This paper presents a global statistical investigation into the topside ionosphere electron density response to X‐class solar flares during geomagnetically quiet conditions (Kp ≤ $\mathit{\le }$ 2) using Swarm satellites (462–511 km) data from 2014 to 2024.

Spacecraft formation-flying using potential functions [PDF]

, 2008
A group of small spacecraft able to change their relative position and attitude through the use of the potential function method is discussed. The spacecraft shapes, sizes and manoeuvring capabilities are not identical, although all are assumed to manoeuvre using continuous thrusters.

Formation Flying of Tethered and Nontethered Spacecraft [PDF]

, 2005
A paper discusses the effect of the dynamic interaction taking place within a formation composed of a rigid and a deformable vehicle, and presents the concept of two or more tethered spacecraft flying in formation with one or more separated free-flying ...

Controlling of the F Region Plasma Structures by the E Region Conductance in the Auroral Ionosphere

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract At high latitudes, the E and F regions of the ionosphere are strongly coupled through nearly vertical magnetic field lines. To simultaneously and directly relate the E and F regions' plasma structures, we ran a coordinated conjunction campaign between Swarm satellites and Incoherent Scatter Radar in Tromsø, Norway, during a moderate ...

Enhancement of Dayside Westward Electrojet: Triggering Conditions and Current Closures

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Geomagnetic substorms are a major path for energy storage and release in the magnetosphere, which typically occur in the midnight sector with a strong enhancement of westward electrojets. However, by analyzing 37,940 events from a substorm list, about 3% of events unexpectedly initiated in the noon sector.

Temporal Variations of Jupiter's Plasma Disk Observed by Juno

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In Jupiter's magnetosphere, a key question is how plasma is transported outward from its source near Io to the distant magnetotail. Since 2016, the plasma disk has been extensively observed by the Juno mission. Using plasma data from the JADE instrument, we perform an analysis revealing significant temporal variation. For different Juno orbits,

The navigation for Formation flying of spacecraft

The navigation for Formation flying of spacecraft
Japan Aerospace Exploration Agency (JAXA) is planning the next generation magnetosphere observation mission called 'SCOPE' (cross-Scale Coupling in Plasma universE). SCOPE aims at observing the Earth's magnetotail with five satellites flying in formation to fully resolve the temporary and spatial distribution of the magnetospheric phenomena in the near
