“…The baseline ESTCube-LuNa E-sail experiment design includes a passive endmass at the tether's tip, which helps to generate the centrifugal force, pull out the tether and keep it stretched. An alternative remote unit solution would help in placing attitude thrusters at the end of the tether where they would be optimal for spin and spin plane control [43]. However, the endmass is preferred in the ESTCube-LuNa concept as an existing solution, while the remote unit remains on our future development roadmap to achieve trajectory control, as proposed in Section 4, where more details on the endmass-remote unit choice are provided.…”

“…For ESTCube-LuNa, the CoM shift is insignificant in terms of the spin rate because it is inside the Debye length and inside the sheath. However, this would change if a remote unit (750 g [43]) was used instead of a passive endmass, introducing a significant shift in CoM when compared with the ESTCube-LuNa endmass of 2.5 g.…”

“…However, to keep the design of the ESTCube-LuNa (i.e., the endmass solution) simple and to facilitate the spin rate modification experiment, the variant with remote unit is not considered for the baseline design. Nevertheless, it is worth noting that a similar architecture has been proposed by Iakubivskyi et al [43] and could be combined with the ESTCube-LuNa concept as a possible next step after the demonstration of the E-sail concept. The same E-sail also provides spin plane control capabilities; however, this aspect has yet to be designed and demonstrated by the ESTCube-LuNa or a similar mission.…”

The electric solar wind sail, or E-sail, is a propellantless interplanetary propulsion system concept. By deflecting solar wind particles off their original course, it can generate a propulsive effect with nothing more than an electric charge. The high-voltage charge is applied to one or multiple centrifugally deployed hair-thin tethers, around which an electrostatic sheath is created. Electron emitters are required to compensate for the electron current gathered by the tether. The electric sail can also be utilised in low Earth orbit, or LEO, when passing through the ionosphere, where it serves as a plasma brake for deorbiting—several missions have been dedicated to LEO demonstration. In this article, we propose the ESTCube-LuNa mission concept and the preliminary cubesat design to be launched into the Moon’s orbit, where the solar wind is uninterrupted, except for the lunar wake and when the Moon is in the Earth’s magnetosphere. This article introduces E-sail demonstration experiments and the preliminary payload design, along with E-sail thrust validation and environment characterisation methods, a cis-lunar cubesat platform solution and an early concept of operations. The proposed lunar nanospacecraft concept is designed without a deep space network, typically used for lunar and deep space operations. Instead, radio telescopes are being repurposed for communications and radio frequency ranging, and celestial optical navigation is developed for on-board orbit determination.

“…The initial SISPO package was developed to assist in the Multi-Asteroid Touring (MAT) mission, where a fleet of nanospacecraft, propelled by electric sails, flys by a large number of main-belt asteroids [25,26]. The MAT concept cannot rely on typical deep-space-networkbased solutions to operate and navigate the fleet; it requires most of the operations to be performed autonomously.…”

This paper describes the architecture and demonstrates the capabilities of a newly developed, physically-based imaging simulator environment called SISPO, developed for small solar system body fly-by and terrestrial planet surface mission simulations. The image simulator utilises the open-source 3-D visualisation system Blender and its Cycles rendering engine, which supports physically based rendering capabilities and procedural micropolygon displacement texture generation. The simulator concentrates on realistic surface rendering and has supplementary models to produce realistic dust- and gas-environment optical models for comets and active asteroids. The framework also includes tools to simulate the most common image aberrations, such as tangential and sagittal astigmatism, internal and external comatic aberration, and simple geometric distortions. The model framework’s primary objective is to support small-body space mission design by allowing better simulations for characterisation of imaging instrument performance, assisting mission planning, and developing computer-vision algorithms. SISPO allows the simulation of trajectories, light parameters and camera’s intrinsic parameters.
