“…Industry, such as automotive or spatial industry, have budgets to follow very strict development processes with international standards, quality insurance, static analysis, and the like [ 49 ]. Such processes cannot be followed each time that a scientist wants to add an application to the Mermaid, it would require budgets that many scientists do not have.…”

At 2000 m depth in the oceans, one can hear biological, seismological, meteorological, and anthropogenic activity. Acoustic monitoring of the oceans at a global scale and over long periods of time could bring important information for various sciences. The Argo project monitors the physical properties of the oceans with autonomous floats, some of which are also equipped with a hydrophone. These have a limited transmission bandwidth requiring acoustic data to be processed on board. However, developing signal processing algorithms for these instruments requires one to be an expert in embedded software. To reduce the need of such expertise, we have developed a programming language, called MeLa. The language hides several aspects of embedded software with specialized programming concepts. It uses models to compute energy consumption, processor usage, and data transmission costs early during the development of applications; this helps to choose a strategy of data processing that has a minimum impact on performances. Simulations on a computer allow for verifying the performance of the algorithms before their deployment on the instrument. We have implemented a seismic P wave detection and a blue whales D call detection algorithm with the MeLa language to show its capabilities. These are the first efforts toward multidisciplinary monitoring of the oceans, which can extend beyond acoustic applications.

“…Before the backdrop of these back-to-back failures, "FBC faded into history [...] leading to a shift back to a balanced government role in managing space program development and implementation" [61]. As a reaction to Abrixas, Germany's space agency firmly embedded its product assurance department and its responsibility for missions and other major projects [2]. But Leveson also criticizes technical aspects of the accident report because it recommends employing techniques developed for hardware, such as redundancy, failure mode and effects analysis, and fault tree analysis, which are not suitable for addressing software-related issues.…”

“…For many missions, there is no second chance if the launch fails or if the spacecraft is damaged or lost, for whatever reason, e.g., because a second flight unit is never built, (cf. [2]) because of long flight time to a destination, or because of a rare planetary constellation that occurs only every few decades. Small series launchers, multi-satellite systems, or satellite constellations that naturally provide some redundancy can, of course, be exceptions to some degree.…”

“…There are direct lines of communication between the customer's and their suppliers' product assurance personnel. For product assurance and engineering, there are software forms called software engineering and software product assurance (see [2]). However, it is important to note that these are organizational roles, whereas both their technical backgrounds are software engineering.…”

Space exploration has become an integral part of modern society, and since its early days in the 1960s, software has grown in importance, becoming indispensable for spaceflight. However, software is boon and bane: while it enables unprecedented functionality and cost reductions and can even save spacecraft, its importance and fragility also make it a potential Achilles heel for critical systems. Throughout the history of spaceflight, numerous accidents with significant detrimental impacts on mission objectives and safety have been attributed to software, although unequivocal attribution is sometimes difficult. In this Entry, we examine over two dozen software-related mishaps in spaceflight from a software engineering perspective, focusing on major incidents and not claiming completeness. This Entry article contextualizes the role of software in space exploration and aims to preserve the lessons learned from these mishaps. Such knowledge is crucial for ensuring future success in space endeavors. Finally, we explore prospects for the increasingly software-dependent future of spaceflight.

“…Quality assurance includes two principles: "Fit for purpose" (the product should be suitable for the intended purpose); and "right first time" (mistakes should be eliminated). The quality in the context of space projects, and report a cross-sectional view from a customer's perspective on various management tools for influencing suppliers' processes and product quality: standards, single-source tailoring and cross-company product assurance [2].…”

This study was aimed to show the implementation of internal quality assurance system at Darul Hikam Islamic School. For this purpose, the researchers used qualitative methods, including analysis of documents, interviews and observations. The results indicated that quality assurance at Darul Hikam was prepared by Darul Hikam College independently, such as in planning, implementing, monitoring and evaluating. Program evaluation internal quality assurance in Darul Hikam, is conducted every semester and performance evaluation, the results of the evaluation are attached in the form of a work report card. The constraint faced by Darul Hikam is the mobility of teachers in and out of the human resources. To minimize the impact of teacher mobilization, Darul Hikam improved teacher's welfare and developed an intensive development package, because teachers and other human resources cannot adopt the system too long. So the human resources development team worked hard to develop new human resources and maintain the quality of the old human resources. Therefore, human resources and the guarantors of Internal Quality Assurance System should make program innovations to strengthen the quality assurance in Islamic School.
