SwissCube is a joint cubesat project of various laboratories at EPFL and universities in Switzerland. [B]Sizing up the Situation[/B] This small cubesat-type satellite, measures just 4 inches by 4 inches (10 centimeters by 10 centimeters). Barring an unforeseen event, SwissCube's demise has been programmed for 2018. The size of SwissCube makes it tough to grasp, but it also has darker and lighter parts that reflect sunlight differently, explains Christophe Paccolat, a PhD student working on the concept. CleanSpace One could be launched as early as 2018 in collaboration with the company S3, headquartered in Payerne. The engineering team is reporting a major step forward in designing an approach and capture system – a so-called "Pac-Man" solution. The prototype CleanSpaceOne resembles a net in the form of a cone that unfolds and then closes back down once it has captured the small satellite. It will trap the small satellite and the two would combust together in the atmosphere. Other work on the initiative involves creating and testing visual approach algorithms on the cleanup satellite's cameras. To be accurate, they must take into account a variety of parameters, [URL='http://espace.epfl.ch/op/preview/page-123348.html']a team press statement notes[/URL], such as the angle of illumination of the sun and the relative speed at which the cubesat is moving through space. [B]Larger Margin[/B] Muriel Richard-Noca, head of the project, emphasizes the extreme delicacy of the mission: "It only takes one error in the calculation of the approach for SwissCube to bounce off CleanSpace One and rocket out into space." Adds Michel Lauria, a professor of industrial technology at Hepia Lab in Geneva: "This system is more reliable and offers a larger margin for maneuvering than a claw or an articulated hand." The next stage of work involves fabricating a more true-to-life engineering model – which will be more accurate than the prototypes – and more extensive testing.
