On Monday, the spacecraft performs standard maintenance on its propulsion systems.
Scientists frequently measure distances from a planet in terms of the radius of that planet.
At these distances, Galileo is expected to be outside of the magnetosphere, measuring the solar wind. On Saturday, commands will be sent to the spacecraft which will govern its activities for the next seven weeks. All of the activities reported in these bulletins are accomplished by such programs, which, in the long periods between flybys, are sent to the spacecraft every month or so.
