Short summary
The boundary of Earth's magnetic field, the magnetopause, deflects and reacts to the solar wind - the energetic particles emanating from the Sun. We find that certain types of solar wind favour the occurrence of deviations between the magnetopause locations observed by spacecraft and those predicted by models. In addition, the turbulent region in front of the magnetopause, the foreshock, has a large influence on the location of the magnetopause and thus on the accuracy of the model predictions.

In our study, we looked at the boundary between the Earth's magnetic field and the interplanetary magnetic field emitted by the Sun, called the magnetopause. While other studies focus on the magnetopause motion near Earth's Equator, we have studied it in polar regions. The motion of the magnetopause is faster towards the Earth than towards the Sun. We also found that the occurrence of unusual magnetopause locations is due to similar solar influences in the equatorial and polar regions.

Educational research highlights that improved careers education is needed to increase participation in science, technology, engineering, and mathematics (STEM). Current UK careers resources in the space sector, however, are found to perhaps not best reflect the diversity of roles present and may in fact perpetuate misconceptions about the usefulness of science. We, therefore, compile a more diverse set of space-related jobs, which will be used in the development of a new space careers resource.

We explore how best to support school students to experience undertaking research-level physics by evaluating provision in the PRiSE framework of
research in schoolsprojects. These experiences are received by students and teachers much more positively than typical forms of outreach. The intensive support offered is deemed necessary, with all elements appearing equally important. We suggest the framework could be adopted at other institutions applied to their own areas of scientific research.

The impacts upon a diverse range of students, teachers, and schools from participating in a programme of protracted university-mentored projects based on cutting-edge physics research are assessed. The lasting impacts on confidence, skills, aspirations, and practice suggest that similar
research in schoolsinitiatives may have a role to play in aiding the increased uptake and diversity of physics/STEM in higher education as well as meaningfully enhancing the STEM environment within schools.

An evaluation of the accessibility and equity of a programme of independent research projects shows that, with the right support from both teachers and active researchers, schools' ability to succeed at undertaking cutting-edge research appears independent of typical societal inequalities.

We show that integrating evaluation tools both before and after a drop-in engagement activity enables the demonstration of change and, thus, short-term impact. In our case, young families who listened to space sounds exhibited changed language and conceptions about space in their graffiti wall responses afterwards, exemplifying the power of sound in science communication. We suggest that evaluation tools be adopted both before and after drop-in activities in general.

The Space Sound Effects Short Film Festival integrated near-Earth space environment research into culture through independent film. By running a film festival challenging filmmakers to incorporate the sounds of space, creative works were produced which have gone on to be screened at numerous established film festivals and events internationally. These events introduced non-science audiences to this area of research which affects their everyday lives, having several unanticipated impacts on them.

Magnetosheath jets are high-velocity plasma structures that are commonly observed within the Earth's magnetosheath. Previously, they have mainly been investigated with spacecraft observations, which do not allow us to infer their spatial sizes, temporal evolution, or origin. This paper shows for the first time their dimensions, evolution, and origins within a simulation whose dimensions are directly comparable to the Earth's magnetosphere. The results are compared to previous observations.

We have studied fast plasma jets outside of Earth’s magnetic environment. Such jets are small-scale structures with a limited lifetime, which may be important in determining the properties of the near-Earth space environment, due to their concentrated kinetic energy. We have used data from the NASA Magnetospheric MultiScale (MMS) satellites to study their properties in detail, to understand how these jets are formed. We have found evidence that there are at least two different types of jets.

The first in-flight results from a new design of miniaturised magnetometer (MAGIC - MAGnetometer from Imperial College), aboard the first CINEMA (Cubesat for Ions, Neutrals, Electrons and MAgnetic fields) spacecraft in low Earth orbit, are presented. Not only can this sensor be used for determining attitude, but it is also able to detect the extremely small (20-40 nT) magnetic field signatures of field-aligned currents at the auroral oval. Thus, there are science capabilities with such sensors.
