Magnetic reconnection as a mechanism to produce multiple protonpopulations and beams locally in the solar wind
B. Lavraud, R. Kieokaew, N. Fargette +37
Context. Spacecraft observations early revealed frequent multiple proton populations in the solar wind. Decades of research on their origin have focused on processes such as magnet…
Deriving the bulk properties of solar wind electrons observed by Solar Orbiter: A preliminary study of electron plasma thermodynamics
Georgios Nicolaou, Robert T. Wicks, Christopher J. Owen +8
We demonstrate the calculation of solar wind electron bulk parameters from recent observations by Solar Wind Analyser Electron Analyser System on board Solar Orbiter. We use our me…
System Modelling of Very Low Earth Orbit Satellites for Earth Observation
N. H. Crisp, P. C. E. Roberts, K. L. Smith +7
The operation of satellites in very low Earth orbit (VLEO) has been linked to a variety of benefits to both the spacecraft platform and mission design. Critically, for Earth observ…
The solar-wind angular-momentum flux observed during Solar Orbiter's first orbit
Daniel Verscharen, David Stansby, Adam J. Finley +19
Aims: We present the first measurements of the solar-wind angular-momentum (AM) flux recorded by the Solar Orbiter spacecraft. Our aim is the validation of these measurements to su…
In-Orbit Aerodynamic Coefficient Measurements using SOAR (Satellite for Orbital Aerodynamics Research)
N. H. Crisp, P. C. E. Roberts, S. Livadiotti +26
The Satellite for Orbital Aerodynamics Research (SOAR) is a CubeSat mission, due to be launched in 2021, to investigate the interaction between different materials and the atmosphe…
A Review of Gas-Surface Interaction Models for Orbital Aerodynamics Applications
Sabrina Livadiotti, Nicholas H. Crisp, Peter C. E. Roberts +29
Renewed interest in Very Low Earth Orbits (VLEO) - i.e. altitudes below 450 km - has led to an increased demand for accurate environment characterisation and aerodynamic force pred…
The Benefits of Very Low Earth Orbit for Earth Observation Missions
N. H. Crisp, P. C. E. Roberts, S. Livadiotti +30
Very low Earth orbits (VLEO), typically classified as orbits below approximately 450 km in altitude, have the potential to provide significant benefits to spacecraft over those tha…
Carbon chain anions and the growth of complex organic molecules in Titan's ionosphere
R. T. Desai, A. J. Coates, A. Wellbrock +12
Cassini discovered a plethora of neutral and ionised molecules in Titan's ionosphere including, surprisingly, anions and negatively charged molecules extending up to 13,800 u/q. In…
LOFT: Large Observatory For X-ray Timing
R. P. Mignani, S. Zane, D. Walton +6
High-time-resolution X-ray observations of compact objects provide direct access to strong field gravity, black hole masses and spins, and the equation of state of ultra-dense matt…
AXIOM: Advanced X-ray Imaging Of the Magnetosphere
G. Branduardi-Raymont, S. F. Sembay, J. P. Eastwood +22
Planetary plasma and magnetic field environments can be studied by in situ measurements or by remote sensing. While the former provide precise information about plasma behaviour, i…
The gamma-ray giant flare from SGR1806-20: Evidence for crustal cracking via initial timescales
Steven J. Schwartz, Silvia Zane, Robert J. Wilson +6
We report here on serendipitous observations of the intense gamma-ray flare from SGR 1806-20 that occured on 27 December 2004. Unique data from the Cluster and Double Star-2 satell…
