With the space industry shifting from large, expensive and long-lived spacecraft towards smaller, inexpensive and short duration spacecraft, there are many advantages to be gained, ranging from better science return to improved access to space. However, as access to space improves, popular orbits are becoming cluttered with spent spacecraft that are not able to remove themselves from orbit due to their lack of an integrated propulsion system (owing to their low-cost design). These spent spacecraft pose a serious collision hazard to operational spacecraft (both manned and un-manned). The space industry needs an inexpensive and self-contained tool for removing spent and potentially failed spacecraft from orbit to reduce the threat of catastrophic collisions.This proposal introduces the Self-Contained Orbit Termination Tool (SCOTT). Designed to be inexpensively manufactured using additive manufacturing technology, SCOTT will provide both orbit and attitude (pointing direction) determination and control capability from one entirely self-contained device. This research project will study the orbital dynamics of re-entering spacecraft, in combination with the pointing control required to accurately direct the thrust required for re-entry and safe spacecraft disposal. This work will also simulate and prototype the thrust generation and thrust vectoring capability of a small self-contained rocket engine that could be added to any spacecraft.Working closely with engineers from Precision ADM, a leading additive manufacturing company in Manitoba, two MSc students from the University of Manitoba will develop a working prototype of SCOTT, using cutting-edge metal additive manufacturing technology that will result in a light-weight, inexpensive yet precisely manufactured product. In addition to providing de-orbit capability for small spacecraft, SCOTT represents a new business opportunity for Precision ADM as they expand into the aerospace market.

随着空间行业从大型，昂贵且长期寿命的航天器转移到较小，廉价且持续时间短的航天器，从更好的科学恢复到改善的空间访问权限，有许多优势可以获得。 但是，随着空间访问的改善，流行的轨道变得混乱，因为缺乏集成的推进系统（由于其低成本设计），由于它们缺乏集成的推进系统，因此无法将自己从轨道上移开。 这些花费的航天器对操作航天器构成了严重的碰撞危险（载人和无人驾驶）。 空间行业需要廉价且具有独立的工具来删除轨道上的消费和潜在失败的航天器，以减少灾难性碰撞的威胁。该提案引入了自载的轨道终止工具（Scott）。 斯科特（Scott）旨在使用增材制造技术廉价地制造出来，可从一个完全独立的设备提供轨道和态度（指向方向）确定和控制能力。 该研究项目将研究重新进入航天器的轨道动力学，并结合准确指示重新进入和安全的航天器处置所需的指向控制。 This work will also simulate and prototype the thrust generation and thrust vectoring capability of a small self-contained rocket engine that could be added to any spacecraft.Working closely with engineers from Precision ADM, a leading additive manufacturing company in Manitoba, two MSc students from the University of Manitoba will develop a working prototype of SCOTT, using cutting-edge metal additive manufacturing technology that will result in a light-weight, inexpensive yet精确制造的产品。 除了为小型航天器提供轨道能力外，斯科特还代表着精密ADM的新商机，因为它们扩展到航空航天市场。
