“…Changing the launch date or time by as little as 15 min could lead to huge differences in how long a satellite remains in orbit. Such information could be used to help calculate the best times to depart the launch pad (Daquin et al ). Bigger debris pieces could be equipped with a sail (Stohlman & Lappas ). Such debris would slow down quicker and burn up in the atmosphere faster than without sail. A space debris fragment shot by a high‐energy, well‐concentrated, pulsing, ground‐born LASER beam on its front surface, starts to evaporate, which results in its slowing down, the consequence of which is its height loss (Esmiller et al ).…”

Space debris larger than 1 cm can damage space instruments and impact Earth. The low-Earth orbits (at heights smaller than 2,000 km) and orbits near the geostationary-Earth orbit (at 35,786 km height) are especially endangered because most satellites orbit at these latitudes. With current technology, space debris smaller than 10 cm cannot be tracked. Smaller space debris fragments burn up and evaporate in the atmosphere, but larger ones fall to Earth's surface.For practical reasons, it would be important to know the mass, composition, shape, velocity, direction of motion, and impact time of space debris re-entering the atmosphere and falling to Earth. Since it is very difficult to measure these physical parameters, almost nothing is known about them. To partly fill this gap, we performed computer modeling with which we studied the dynamics of spherical re-entry particles falling to Earth due to air drag. We determined the time, velocity, and angle of impact as functions of the launch height, direction, speed, and size of spherical re-entry particles. Our results can also be used for semispherical meteoroid particles of the interplanetary dust entering the Earth's atmosphere.

“…The primary payload will be a 5-by-5-meter sail, which will be deployed in orbit and used to demonstrate drag deorbiting. The satellite bus will have communications and attitude control for optimal drag orientation, and is described in greater detail by another paper presented at this conference [1]. Much work had been done, by Deorbitsail partners as well as the space industry in general, on deployable sails.…”

Deorbitsail is a 3U Cubesat project that will launch, deploy, and support a large drag sail deorbiting payload. The flight payload sail system will deploy to 5 by 5 meters, increasing the frontal area of the spacecraft dramatically. A series of 4-by-4-meter sail deployments has been performed with a prototype of the proposed system. The prototype system tests included partial deployments in environmental chambers and full-scale deployment at ambient lab conditions. Design changes arising from testing of the sail system prototype are described in this paper. Engineering model construction is underway and the Deorbitsail launch will be in 2014. Deorbitsail is a European Commission 7th Framework Programme project with nine partner organizations. © 2013 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved

“…On the other hand, the developments of lightweight membrane structures mounted on spacecrafts and deployed with booms, such as solar sails, 4) de-orbit sails, 5) sun shields, thin film solar arrays, and so on, is an important subject at present. Incorporating elastic elements in the multi-particle method is necessary to study their deployment dynamics.…”

Deployable membrane structures are hopeful to develop future lightweight large space structures. In order to predict the dynamic behaviors of the structures in the preliminary design phase, simple and fast numerical simulation is necessary. For this purpose, multi-particle approximation method has been studied which models membranes with spring-mass-damper systems. In this study, polygonal membrane structures integrated with extendible booms are investigated. The membranes are deployed by the elasticity of the booms in a stepwise manner. A multi-particle model for one-dimensional elastic body is introduced as the boom model to the multi-particle method. Each boom is released from the tip end by several particles and the dynamic behaviors of the stepwise deployment can be obtained. The behaviors are compared with deployment experiments of booms without a membrane. Numerical simulation of the deployment of a hexagonal membrane with booms is also demonstrated. Finally, the effect of the stepwise pattern on the vibration motion of the central body due to deployment is studied.
