Space environment mission simulation and Australian radiation testing of components for the Buccaneer Main Mission MANTIS payload
Abstract
The Maneuverable ANtenna Terrestrial and self-Imaging System (MANTIS) payload for DST's Buccaneer Main Mission (BMM) will include a deployable and retractable arm with a 3D printed metal rotatable mirror, and an internally housed camera with a liquid lens capable of imaging Earth and the BMM cubesat itself. Liquid lenses allow imaging systems to overcome depth of field limitations by allowing the focus to be electronically adjusted without requiring any mechanical movement, providing significant utility in optical imaging with small satellite missions. However these lenses have little literature or measurements of the effects of the space environment, particularly radiation, which is known to cause several unwanted effects in electronics. This includes ionising radiation that contributes to the gradual cumulative degradation of materials, known as Total Ionizing Dose (TID), and Single Event Effects (SEE) occurring when a single incident ion causes a high degree of ionisation in a small volume. This talk will cover how teams can simulate the expected radiation environments during an orbit using tools such as ESA's Space Environment Information System (SPENVIS), as well as results of the radiation testing using two facilities in Australia; Australia's Nuclear Science and Technology Organisation (ANSTO) Cobalt-60 Gamma Irradiation facility; and the Australian National University's (ANU) Heavy Ion Accelerator Facility.
