Blyfri loddetin 2

Fandt også lidt om situationen for vores relæstationer derude i den tynde luft ;-)

------- cut --------------- The tin-whiskers problem was first noticed in the HS 601 series of satellites, which includes both Galaxy 4 and Solidaridad 1, in late

1997. Since then, the tin-plated relays have been replaced with nickel-plated ones, which are immune from the whiskers problem, on newer satellites.

Sunday's failure is not the first for Solidaridad 1. In April 1999 the primary spacecraft control processor failed, but control of the spacecraft was restored with a backup processor, which then failed on Sunday.
