Polarimeter to Unify the Corona and Heliosphere (PUNCH)

C. E. DeForest, S. E. Gibson, Ronnie Killough, Nick Waltham et autres

Abstract The Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission is a NASA Small Explorer to determine the cross-scale processes that unify the solar corona and heliosphere. PUNCH has two science objectives: (1) understand how coronal structures become the ambient solar …

Introduction to procurement methods in construction

S. P. Plunkett

The client’s level of experience will be an important factor in the process of choosing an appropriate procurement method. Whilst a professional client experienced in construction projects may be willing to take on more responsibility, a ‘one-off’ client is likely to look …

The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action

I. Zouganelis, A. De Groof, A. P. Walsh, David R. Williams et autres

Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand how the Sun produces and controls the heliosphere, filling the …

Modeling inner boundary values at 18 solar radii during solar quiet time for global three-dimensional time-dependent magnetohydrodynamic numerical simulation

Chin‐Chun Wu, K. Liou, Brian E. Wood, S. P. Plunkett et autres

We develop an empirical model of the solar wind parameters at the inner boundary (18 solar radii, R s ) of the heliosphere that can be used in our global, three-dimensional (3D) magnetohydrodynamic (MHD) model (G3DMHD) or other equivalent ones. The model …

Coordination within the remote sensing payload on the Solar Orbiter mission

F. Auchère, V. Andretta, E. Antonucci, N. Bach et autres

Context.To meet the scientific objectives of the mission, the Solar Orbiter spacecraft carries a suite of in-situ (IS) and remote sensing (RS) instruments designed for joint operations with inter-instrument communication capabilities. Indeed, previous missions have shown that the Sun (imaged by the …
