A gravity assist at Jupiter was the key to the mission, allowing Ulysses to arc out of the ecliptic and inward to the Sun. But Ulysses lacked the kind of remote-sensing instruments we’d like to use to compile an extensive dataset on the polar magnetic field and, as Don Hassler (SwRI) adds, “the surface/sub-surface flows” we might find in the polar regions. It’s good to see a mission designed for that purpose.
For Hassler is principal investigator on a concept that has just been approved for further study by NASA, with the haunting name Solaris. I say ‘haunting’ because it’s hard for this Stanislaw Lem reader to forget the novel of the same name, published in 1961, that explores the implications of a vast intelligence on a planet far from Earth.
