Electrochromic orbit control for smart-dust devices [PDF]
, 2012 Recent advances in MEMS (micro electromechanical systems) technology are leading to spacecraft which are the shape and size of computer chips, so-called SpaceChips, or ‘smart dust devices’.

Prediction of the aerodynamic performance of re-usable single stage to orbit vehicles [PDF]
, 2011 Re-usable single stage to orbit launch vehicles promise to reduce the cost of access to space, but their success will be particularly reliant on accurate modelling of their aero-thermodynamic characteristics.

On-Orbit Manoeuvring Using Superquadric Potential Fields [PDF]
, 2007 On-orbit manoeuvring represents an essential process in many space missions such as orbital assembly, servicing and reconfiguration. A new methodology, based on the potential field method along with superquadric repulsive potentials, is discussed in this

Obstacle Avoidance in a Three-Dimensional Dynamic Environment Based on Fuzzy Dynamic Windows
Applied Sciences, 2021 This paper presents a real-time path planning approach for controlling the motion of space-based robots. The algorithm can plan three-dimensional trajectories for agents in a complex environment which includes numerous static and dynamic obstacles, path ...

Design and Dynamic Control: A Free-Flying Space Robot Inspired by Water Striders
Biomimetics, 2023 This work designed a free-flying space robot (FFSR) that simulates the on-orbit assembly of large space telescopes, drawing inspiration from the flexible movement of water striders on water surfaces.

Frobenius Manifolds on Orbits Spaces
Mathematical Physics, Analysis and Geometry, 2022 The orbits space of an irreducible linear representation of a finite group is a variety whose coordinate ring is the ring of invariant polynomials. Boris Dubrovin proved that the orbits space of the standard reflection representation of an irreducible finite Coxeter group $\mathcal W$ acquires a natural polynomial Frobenius manifold structure. We apply

Finitistic Spaces with Orbit Space a Product of Projective Spaces
, 2023 Let G = Z2 act freely on a nitistic space X. If the mod 2 cohomology of X is isomorphic to the real projective space RP^{2n+1} (resp. complex projective space CP^{2n+1}) then the mod 2 cohomology of orbit spaces of these free actions are RP1 x CPn (resp. RP2 x HPn) [7]. In this paper, we have discussed converse of these results. We have showed that if
