a question for Q&BA - and my first post so i hope it ends up where intended !

if the aim of the Ulysses misssion is to collect data from above the polar regions of the sun,why is it placed in an orbit that spends so little time in those regions and sends it to cold places where it risks power failures ? is there some special problem in putting instruments into orbit in a plane at right angles to the plane of the earth around the sun ?

if the great Phil is unable to put this into his reply slot, is anyone esle able to offer a reason ?

thanks for all the fish
