“…Magnetic induction charging (V ISS x B· L) has been previously reported [Ferguson et al, 2001Mikatarian et al,2004;Ferguson, 2004;Reddell et al, 2006]. Eclipse exit has also been recognized as an area where charging is likely to be maximized Reddell et al, 2006] and this is seen in our normal eclipse charging as well as in data previously obtained on the ISS by the Glenn Research Center Floating Potential Probe in 2001 [Ferguson et al 2001;. Three apparently new categories can be added based on this survey: equatorial, high latitude night-time, and rapid eclipse exit charging.…”

“…Magnetic induction charging shows a sinusoidal-like character. This is a well explained behavior of spacecraft potentials [Whipple, 1981;Mikatarian et., 2004;Ferguson, 2004;Reddell et al, 2006], is always present throughout the ISS orbit, and is dependent on the velocity of the ISS, the earth's magnetic field, and the position of the FPMU on the truss through the relation V ISS xB·L, where V ISS is the ISS velocity, B is the local magnetic field strength, and L is a position vector to the FPMU. With the ISS in +XVV attitude, the potential at the FPMU location is largest at the higher northern latitudes and smallest at the higher southern latitudes where the high V ISS xB·L potential is on the end of the truss opposite the position of the FPMU.…”

With the negative grounding of the 160V Photovoltaic (PV) arrays, the International Space Station (ISS) can experience varied and interesting charging events. Since August 2006, there has been a multi-probe package, called the Floating Potential Measurement Unit (FPMU), available to provide redundant measurements of the floating potential of the ISS as well as the density and temperature of the local plasma environment. The FPMU has been operated during intermittent data campaigns since August 2006 and has collected over 160 days of information regarding the charging of the ISS as it has progressed in configuration from one to three PV arrays and with various additional modules such as the European Space Agency's Columbus laboratory and the Japan Aerospace Exploration Agency's Kibo laboratory. This paper summarizes the charging of the ISS and the local environmental conditions that contribute to those charging events, both as measured by the FPMU.

Wakes behind spacecraft caused by supersonic drifting positive ions are common in plasmas and disturb in situ measurements. We review the impact of wakes on observations by the Electric Field and Wave double‐probe instruments on the Cluster satellites. In the solar wind, the equivalent spacecraft charging is small compared to the ion drift energy and the wake effects are caused by the spacecraft body and can be compensated for. We present statistics of the direction, width, and electrostatic potential of wakes, and we compare with an analytical model. In the low‐density magnetospheric lobes, the equivalent positive spacecraft charging is large compared to the ion drift energy and an enhanced wake forms. In this case observations of the geophysical electric field with the double‐probe technique becomes extremely challenging. Rather, the wake can be used to estimate the flux of cold (eV) positive ions. For an intermediate range of parameters, when the equivalent charging of the spacecraft is similar to the drift energy of the ions, also the charged wire booms of a double‐probe instrument must be taken into account. We discuss an example of these effects from the MMS spacecraft near the magnetopause. We find that many observed wake characteristics provide information that can be used for scientific studies. An important example is the enhanced wakes used to estimate the outflow of ionospheric origin in the magnetospheric lobes to about normal10 26 cold (eV) ions/s, constituting a large fraction of the mass outflow from planet Earth.
