SMART-1 is one month in orbit
Eurpean Space Agency
October 29, 2003

Summary of overall status, current activities and planned activities
In this period we have also experienced an autonomous shut-down, or flame-out,
of the engine. This happened on 26 October 2003 at 19:23 UTC, a few hours before
a scheduled switch-off. The engine then re-ignited autonomously at the next
scheduled thrusting restart without problems. The experts are investigating the
problems. One curious coincidence is that at exactly the same time the radiation
monitors on two ESA scientific spacecraft in highly elliptical orbits (XMM and
Integral) had detected considerable radiation coming probably from a solar flare.
This event was so large and potentially dangerous that one instrument on board
Integral stopped operations and switched itself in to safe mode.

The SMART-1 is doing a leisurely float through the Van Allen belt, no?

I would think it'd be designed to withstand radiation.
