Jay writes that Mir predictions will be affected by its manoeuvres. In "New Scientist" (issue 2131, 25 April 1998, page27) Nigel Henbest writes "Mir is continually boosted to save it from a similar fate." Have I missed something? I have not detected a single orbital boost for Mir for at least six months, and this confirms Tony Beresford's opinion. Has anyone got an idea what was the date of the last raising of Mir's orbit? ----------------------------------------------------------------------------- best wishes Russell Eberst @ North: 55 degrees, 56 minutes, 55 seconds West: 3 degrees, 8 minutes, 18 seconds: 43metres (150 feet) above sea-level -----------------------------------------------------------------------------
