Mantellato R (2015) Investigation of deorbiting systems using passive electrodynamic propulsion. PhD thesis The advantages of tether systems are not limited to the disposal manoeuvre, as flexible connections between two modules reduce the loads transmitted between them with respect to solid joints. Furthermore, with such connections the vehicles involved can remain at a safe distance while maintaining a physical connection. For this reason, tethers have been also proposed for space tug configurations and both experimental investigation [ 31, 32] and simulation activities [ 9, 33, 34] have been carried out. The final chapter set in a Museum of Oddities is as thrilling as the first. At the end, we do not know all; as the final sentence states: “There was great deal of work to be done”. In truth, Campion does not play a very active role as he has in most of Allingham's previous series where he is usually the main character, but it is a chance question that he asks which sets the climax of the story into motion. I won't say any more, but if you were only going to read one Campion, this one might be it. Most excellent; highly recommended.

Adv Space Res 65(1):351–363 To date, many investigations of space tethers are for applications in debris removal. The growing problem of space debris and their influence on the access to orbit became commonly recognized by the scientific community after the definition of the so-called “Kessler Syndrome” [ 13], introducing the risk of losing access to Earth orbit regions due to the constant growth of debris and the consequent catastrophic impacts cascade effect. Despite efforts to reduce new spacecraft influence on the debris environment (e.g., [ 14, 15]), the recent plans for large constellations [ 16, 17] are constantly scrutinized and their short and long term influence on the space debris environment stability is under evaluation [ 18, 19, 20]. In this context the scientific community is evaluating further mitigation strategies, considering both the utilization of enhanced protections [ 21] and the implementation of post mission disposal (PMD) [ 22] and active debris removal (ADR) [ 23] operations. Among the different strategies for PMD and ADR [ 24], Electrodynamic Tethers (EDTs) have been investigated as a reliable and convenient solution in low-Earth orbit (LEO) [ 25, 26]. For further information on EDTs and the most recent evolution, the low-working-function tethers (LWTs), see [ 27, 28, 29, 30].

Aerospace 6(6):73 Among the several in-space (e.g.: TSS-1 [ 42, 48], ProSEDS [ 49]—cancelled after Shuttle Columbia accident, YES II [ 50, 51], SEDS [ 52], SEDS II [ 53]) and ground verifications on deployment mechanisms ([ 44, 45, 54]), only the TSS-1 [ 48] and the STAR prototype [ 45] demonstrated the ability to reel in. More recently, the TEPCE CubeSat technology demonstrator was conceived and flown to deploy a 1-km-long tether; to date, confirmation of 500-m deployment is available [ 55]. The low success rate of tethered systems can be related to the complexity of deployment operations, in which minimal disturbances such as internal components friction can greatly influence the reel-out process up to stop completely the tether deployment. For this reason, the proposed deployer employs a system of motorized pulleys to control the tether motion and to decouple the internal mechanism dynamics from the external motion subjected to orbital dynamics.
