Engine failure for Japan’s Procyon probe
The failure of the ion engine of an experimental cubesat called Procyon, launched with Hayabusa-2 to test small satellite technologies, has forced engineers to cancel their attempt to have the probe fly past a different asteroid.
They think dust in the engine caused a short circuit.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

I hope this is not a problem for ion thrusters as such.
Frankly I think we should be focusing our efforts in propulsion on MPD thrusters rather then ion powered “mouse farts.” The MPD has been shown to have superior specific impulse and provide much, much greater thrust then then it’s ion counterpart. The only drawbacks to the design is that an MPD thruster requires a great deal of power (much more then ion engines, but that’s what provides the greater fuel efficiency and thrust) and the only viable way to provide that power is with a nuclear source, but of course, we are all terrified of anything nuclear in space. The MPD’s also have an annoying habit of eroding their Anodes, but as I said, this is where our efforts should be directed. Once the Anode problem has been conquered, all that is left is to attach the engine to a suitable power supply. After that we’ll have the perfect electric propulsion system for going just about anywhere in our solarsystem.
