Multi-Spacecraft Measurement of Turbulence within a Magnetic Reconnection Jet [PDF]
, 2015 The relationship between magnetic reconnection and plasma turbulence is investigated using multipoint in-situ measurements from the Cluster spacecraft within a high-speed reconnection jet in the terrestrial magnetotail.

Intensities and spatiotemporal variability of equatorial noise emissions observed by the Cluster spacecraft [PDF]
Journal of Geophysical Research: Space Physics, 2015 AbstractEquatorial noise (EN) emissions are electromagnetic waves observed in the equatorial region of the inner magnetosphere at frequencies between the proton cyclotron frequency and the lower hybrid frequency. We present the analysis of 2229 EN events identified in the Spatio‐Temporal Analysis of Field Fluctuations (STAFF) experiment data of the ...

The ULF wave foreshock boundary: Cluster observations [PDF]
, 2015 The interaction of backstreaming ions with the incoming solar wind in the upstream region of the bow shock gives rise to a number of plasma instabilities from which ultra-low frequency (ULF) waves can grow.

ION INJECTION AT QUASI-PARALLEL SHOCKS SEEN BY THE CLUSTER SPACECRAFT
The Astrophysical Journal Letters, 2016 ABSTRACT Collisionless shocks in space plasma are known to be capable of accelerating ions to very high energies through diffusive shock acceleration (DSA). This process requires an injection of suprathermal ions, but the mechanisms producing such a suprathermal ion seed population are still not fully understood. We study acceleration of

Long term and safe relative orbit design for heterogeneous spacecraft clusters
Advances in Space Research, 2021 Abstract The problem of obtaining long term relative orbit configurations for spacecraft clusters with realistic operational considerations such as safety, station keeping and inter-spacecraft distances is addressed. Two different approaches are developed for station keeping and safety objectives. In the first approach, relative orbit configurations,

Electric Field Driven Soft Morphing Matter
Advanced Materials, EarlyView.This study presents soft morphing matter robots that exhibit extremely high morphological adaptability and complex multimodal electric field response. They can undergo large, controlled body deformation and show complex locomotion on different terrains under the manipulation of external electric fields, making a significant step beyond current ...

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.

Quasiperiodic emissions observed by the Cluster spacecraft and their association with ULF magnetic pulsations [PDF]
Journal of Geophysical Research: Space Physics, 2013 Quasiperiodic (QP) emissions are electromagnetic waves at frequencies of about 0.5–4 kHz characterized by a periodic time modulation of the wave intensity, with a typical modulation period on the order of minutes. We present results of a survey of QP emissions observed by the Wide‐Band Data (WBD) instruments on board the Cluster spacecraft.
