The number of small satellites launches has seen a considerable growth in recent years as their applications increase for both, scientific and commercial missions. The paradigm of large, reliable, and costly satellites is shifting to low-cost, smalle

There has been an increasing interest in on-orbit autonomous servicing and repair of satellites as well as controlled active debris removal (ADR) in the space industry recently. One of the most challenging tasks for servicing/repair as well as for AD

The work presented in this paper leverages existing progress in angles-only navigation to develop optimal range observability maneuvers and trajectory planning methods for spacecraft formations under constrained relative orbital motion. Relative moti

This work contains some structural results for von Neumann algebras arising from measure preserving actions by direct products of groups on probability spaces. The technology and the methods we use are a continuation of those used by Chifan and Sincl

We define $\Gamma_q(B,S \otimes H)$, the generalized $q$-gaussian von Neumann algebras associated to a sequence of symmetric independent copies $(\pi_j,B,A,D)$ and to a subset $1 \in S = S^* \subset A$ and, under certain assumptions, prove their stro

Impacts on planetary bodies can lead to both prompt secondary craters and projectiles that reimpact the target body or nearby companions after an extended period, producing so-called “sesquinary” craters. Here we examine sesquinary cratering on t
