Analysis of plasmaspheric plumes: CLUSTER and IMAGE observations [PDF]

Annales Geophysicae, 2006
Plasmaspheric plumes have been routinely observed by CLUSTER and IMAGE. The CLUSTER mission provides high time resolution four-point measurements of the plasmasphere near perigee.

South-north asymmetry of field-aligned currents in the magnetotail observed by Cluster [PDF]

, 2010
We statistically investigated features of the field-aligned current (FAC) distribution in plasma sheet boundary layers between 17 and 19 RE in the magnetotail using the curlometer technique to calculate the current from four-point magnetic field ...

Launch support: Managing complementor bottlenecks in the disruptive innovation of small satellites

Strategic Management Journal, EarlyView.
Abstract Research Summary Through both qualitative and quantitative analyses of large‐rocket providers' support for small‐satellite manufacturers before the emergence of small rockets, we examine how disruptors to an incumbent ecosystem gain support from complementors of the incumbent technology.

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, EarlyView.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

EU Space Law and Earth's Boundaries: Integrating Environmental Impact Assessment and Corporate Due Diligence

Global Policy, EarlyView.
ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

Meteoritics &Planetary Science, EarlyView.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...
