“…The approach combines Model-Based Testing (MBT) and Model-Driven Engineering (MDE) techniques to support: (i) specification of interoperability requirements, whose behavior is modeled in state machines; (ii) automated software code generation from those models to be embedded in Arduino computer boards; (iii) automated generation of nominal test cases focusing on interoperability properties; (iv) extension of models with robustness aspects; and finally (v) automated generation of test cases focusing on robustness properties. Moreover, a failure emulator mechanism framework (FEM) is proposed in [18] for robustness testing of interoperable software-intensive subsystems on-board nanosatellite. FEM acts in the communication channel being part of the integration test workbench in two phases of nanosatellite design: (i) robustness requirement specification using model in the loop (MIL) and (ii) robustness validation using hardware in the loop (HIL).…”

CubeSat-based nanosatellites are composed of COTS components and rely on its structure and standardized interfaces. A challenge in the nanosatellites context is to adapt the V&V (Verification and Validation) process to answer to the increase importance of the embedded software, to reduce the artefacts to be delivered aiming at cutting cost and time and still complying with international standards. This work presents an analysis of the strategy adopted in a real nanosatellite for the development of the OBDH software embedded in NanosatC-BR2 mission. The goal is to discuss the impact that the standardization of the structure and interfaces of the CubeSat impose on the V&V process of the SiS and to highlight the challenges of "New Space Age" for the use of existing V&V techniques and methods.

“…With respect to the second factor, the development teams may increase the reliability of the components by testing them in an appropriate environment at early stages of the development process. For this purpose, the utilization of hardware-in-the-loop simulation techniques for nanosatellites is proposed in References [41,42]. In such simulations, prototyped components can be integrated with other emulated components, and tested against their specifications through fault injection.…”

The current success rate of CubeSat missions, particularly for first-time developers, may discourage non-profit organizations to start new projects. CubeSat development teams may not be able to dedicate the resources that are necessary to maintain Quality Assurance as it is performed for the reliable conventional satellite projects. This paper discusses the structured life-cycle of a CubeSat project, using as a reference the authors’ recent experience of developing and operating a 2U CubeSat, called qbee50-LTU-OC, as part of the QB50 mission. This paper also provides a critique of some of the current poor practices and methodologies while carrying out CubeSat projects.

“…human cells. There is, so called, "late access" option, which allows for the payload preparation of about 24 hours before the launch, but it is unfortunately relatively expensive and does not consider unknown mission constraints which can substantially extend the time before the fundamental part of the test starts [24][25]. Typically, CubeSats with the biological payload prior to launch are kept in satellites hangar, in ambient temperature (17°C -22°C).…”

In the paper, the lab-on-chip platform applicable for the long-term cultivation of the human cancer cells, as a solution meeting the demands of the CubeSat astrobiological missions has been presented. For the first time, the selected cancer cell lines – UM-UC-3 and RT112 were cultured on-chip for up to 50 days. The investigation has been done in stationary conditions (without medium microflow) in ambient temperature, and utilizing microflow perfusion system in the incubation chamber assuring typical cultivation atmosphere (37 ºC). All the experiments were performed to imitate the conditions that are provided before the astrobiological mission starts (waiting for the rocket launch) and when the actual experiment is initialized on a CubeSat board in space microgravity. The results of the tests have shown appropriate performance of the LOC platform, especially in the context of material and technological biocompatibility. Cultured cells were characterized by adequate morphology – high attachment rate and visible signs of proliferation in each of the experimental stage. These results are a good base towards further tests of the LOC platform in both terrestrial and space conditions.
