An Iterative Guidance and Navigation Algorithm for Orbit Rendezvous of Cooperating CubeSats
Applied Sciences, 2022 Modern space missions often require satellites to perform guidance, navigation, and control tasks autonomously. Despite their limited resources, small satellites are also involved in this trend, as in-orbit rendezvous and docking maneuvers and formation ...

Implications for the missing low-mass galaxies (satellites) problem from cosmic shear [PDF]
, 2018 The number of observed dwarf galaxies, with dark matter mass $\lesssim 10^{11}$ M$_{\odot}$ in the Milky Way or the Andromeda galaxy does not agree with predictions from the successful $\Lambda$CDM paradigm.

NEOWISE: Observations of the Irregular Satellites of Jupiter and Saturn [PDF]
, 2015 We present thermal model fits for 11 Jovian and 3 Saturnian irregular satellites based on measurements from the WISE/NEOWISE dataset. Our fits confirm spacecraft-measured diameters for the objects with in situ observations (Himalia and Phoebe) and ...

Deployable Tensegrity Reflectors for Small Satellites [PDF]
, 2002 Future small satellite missions require low-cost, precision reflector structures with large aperture that can be packaged in a small envelope. Existing furlable reflectors form a compact package which, although narrow, is too tall for many applications ...

Constraints from deuterium on the formation of icy bodies in the Jovian system and beyond
, 2008 We consider the role of deuterium as a potential marker of location and ambient conditions during the formation of small bodies in our Solar system. We concentrate in particular on the formation of the regular icy satellites of Jupiter and the other ...
