Unfortunately, the most recent update is May 6. It's been a month since then! C'mon NASA, get it together.
Here's a more recent article about Juno from Scientific American, explaining why this mission is going to Jupiter. Still doesn't say how far away it is. Best I could do is find out that on May 27, Juno crossed the boundary where the planet's gravitational pull exceeds that of the now-distant Sun.
Anyway, it arrives at Jupiter on July 4. How appropriate is that?
