The New Horizons Spacecraft [PDF]
Space Science Reviews, 2008 The New Horizons spacecraft was launched on 19 January 2006. The spacecraft was designed to provide a platform for seven instruments that will collect and return data from Pluto in 2015. The design drew on heritage from previous missions developed at The Johns Hopkins University Applied Physics Laboratory (APL) and other missions such as Ulysses.

Spacecraft Floating Potential Measurements for the Wind Spacecraft
The Astrophysical Journal Supplement Series, 2023 Abstract Analysis of 8,804,545 electron velocity distribution functions, observed by the Wind spacecraft near 1 au between 2005 January 1 and 2022 January 1, was performed to determine the spacecraft floating potential, ϕ sc. Wind was designed to be electrostatically clean, which helps keep the magnitude of ϕ

Sheath ionization model of beam emissions from large spacecraft [PDF]
, 1985 An analytical model of the charging of a spacecraft emitting electron and ion beams has been applied to the case of large spacecraft. In this model, ionization occurs in the sheath due to the return current.

Active spacecraft potential control system selection for the Jupiter orbiter with probe mission [PDF]
, 1977 It is shown that the high flux of energetic plasma electrons and the reduced photoemission rate in the Jovian environment can result in the spacecraft developing a large negative potential.
