LARGE SCALE STATIC. “Differential charging of spacecraft surfaces can lead to harmful discharges, which introduce noise to the system and may interrupt normal spacecraft operations and/or represent false commands for the spacecraft. The discharge breakdown can cause physical damage which can change the satellite conductivity or thermal, chemical or optical properties.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

"THE ISLAND OF KNIGHTS AND KNAVES.” There is a wide variety of puzzles about an island in which certain inhabitants called 'knights' always tell the truth, and others called ‘knaves’ always lie. It is assumed that every inhabitant of the island is either a knight or a knave. In this problem, there are only two people, a and b, each of whom is either a knight or a knave; a makes the following statement: 'At least one of us is a knave'. What are a and b?" https://lnkd.in/dEsbUHm View in LinkedIn

EXTREME STATIC. “Moderate-energy electrons associated with substorms cause spacecraft surface charging. During a surface charging event, insulated surfaces may charge to several kilovolts potential (typically negative relative to the ambient plasma).” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

FRIED ELECTRONICS. “The discharges can produce short-lived (fractions of a microsecond) but intense (several Amperes) current pulses. As the anomalies tend to occur only during relatively long-duration events, it is not only the peak intensity of the electron flux but also the duration of the exposure that determines the amount of excess charge accumulation.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

BURIED ELECTRONS. “The excess negative charge can give rise to potential differences, which in turn can lead to intense voltage discharges and surges of electric energy deep inside the electric circuits of the spacecraft causing severe damage to various subsystems.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn
