- Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the exploration of a little-processed long-period comet, possibly entering the inner Solar System for the first time, or to encounter an interstellar object originating at another star. The objectives of the mission are to address the following questions: What are the surface composition, shape, morphology, and structure of the target object? What is the composition of the gas and dust in the coma, its connection to the nucleus, and the nature of its interaction with the solar wind? The mission was proposed to the European Space Agency in 2018, and formally adopted by the agency in June 2022, for launch in 2029 together with the Ariel mission. Comet Interceptor will take advantage of the opportunity presented by ESA’s F-Class call for fast, flexible, low-cost missions to which it was proposed. The call required a launch to a halo orbit around the Sun-Earth L2 point. The mission can take advantage of this placement to wait for the discovery of a suitable comet reachable with its minimum Δ V capability of 600 ms − 1 . Comet Interceptor will be unique in encountering and studying, at a nominal closest approach distance of 1000 km, a comet that represents a near-pristine sample of material from the formation of the Solar System. It will also add a capability that no previous cometary mission has had, which is to deploy two sub-probes – B1, provided by the Japanese space agency, JAXA, and B2 – that will follow different trajectories through the coma. While the main probe passes at a nominal 1000 km distance, probes B1 and B2 will follow different chords through the coma at distances of 850 km and 400 km, respectively. The result will be unique, simultaneous, spatially resolved information of the 3-dimensional properties of the target comet and its interaction with the space environment. We present the mission’s science background leading to these objectives, as well as an overview of the scientific instruments, mission design, and schedule.

A Research Agenda to Better Understand the Human Dimensions of Energy Transitions

Tidskriftsartikel (refereegranskat)abstract
- The Social Sciences and Humanities (SSH) have a key role to play in understanding which factors and policies would motivate, encourage and enable different actors to adopt a wide range of sustainable energy behaviours and support the required system changes and policies. The SSH can provide critical insights into how consumers could be empowered to consistently engage in sustainable energy behaviour, support and adopt new technologies, and support policies and changes in energy systems. Furthermore, they can increase our understanding of how organisations such as private and public institutions, and groups and associations of people can play a key role in the sustainable energy transition. We identify key questions to be addressed that have been identified by the Platform for Energy Research in the Socio-economic Nexus (PERSON, see person.eu), including SSH scholars who have been studying energy issues for many years. We identify three main research themes. The first research theme involves understanding which factors encourage different actors to engage in sustainable energy behaviour. The second research theme focuses on understanding which interventions can be effective in encouraging sustainable energy behaviour of different actors, and which factors enhance their effects. The third research theme concerns understanding which factors affect public and policy support for energy policy and changes in energy systems, and how important public concerns can best be addressed as to reduce or prevent resistance.

HealthCloud : promoting healthy living through co-design of user experiences in a digital service

Konferensbidrag (refereegranskat)abstract
- The aim of the interdisciplinary HealthCloud pre-study project was twofold: to furtherknowledge of user experiences of inclusive interface design specifically for an ageingpopulation, and to develop a digital service for senior persons with sensory decline to promotehealthy living and active ageing. A co-design approach was chosen to investigate the projectaim and knowledge and user experiences was jointly developed and evaluated in threesequential steps in a participant-group of senior persons. In the design of the conceptual userinterface, the identified core aspect involved a strive for utility: quality of appropriateness inuse, and significance: how designs assume meaning in the ways they are used, as well assimplicity: to reduce, organize, and making it enjoyable to use. The digital service outcomeconsists of validation of previous research themes: keeping the family together; enjoying lifeat home; being close to nature; self-development; and promoting conditions for healthyageing. The pre-study project outcomes are prototypes of digital health service content andinterfaces, aimed for a future digital HealthCloud service. Participants in the reference-groupfound the developed interface easy to use regardless of previous computer skills and theywere also motivated and stimulated by the developed prototypes for promoting active ageingon a daily basis. Participants also expressed a desire to display and recommend such digital

HealthCloud : Participatory design of user interfaces for senior people's active aging
- 2017
-
Rapport (populärvet., debatt m.m.)abstract
- The aim of the HealthCloud project has been twofold: to develop knowledge of user needs for interface design specifically for an ageing population, and also to develop a user interface design specially designed for senior persons with sensory decline to promote healthy living through five Core Health Projects. A participatory approach was chosen to investigate the aim of the project and data was collected and analysed in three sequential steps. A reference-group with senior citizens recruited from retirement organizations interactively evolved data for the project during three workshops. The continuous interaction with the reference group resulted in a conceptual user interface design aimed for the digital HealthCloud service. In the design of the conceptual user interface, the identified core factors were a strive for simplicity: to reduce, organize, and make it enjoyable to use. Participants in the reference-group found the developed interface easy to use regardless of previous computer skills and they were also motivated and stimulated by the interface to start using the computer for promoting their health om a daily basis. Participants also wanted to display and recommend this interface to other members of retirement organizations.
