I must confess that this press release sounds a little bit hyped-up to me. huh.gif Flybys at Phobos of Mars Express are known and science investigations are planned months in advance.

Perhaps a bit. It certainly seems like it's getting a fair amount of attention from the world press. However, I can also see why they might want that, and it's an interesting story in its own right for people who do not ordinarily pay much attention to robotic spaceflight. smile.gif

Are any science observations being done by Maven?

The article doesn't state if it will?

It was observed in ultraviolet in December 2015, 500 kilometres away: http://mars.nasa.gov/news/2016/maven-obser...far-ultraviolet

Not sure if they'll do any new measurements this time; how far will this flyby be in distance?

Not sure. Phobos' orbital velocity is a bit more than 2.1 km/sec, and the press release says that the avoidance maneuver allows MAVEN to miss the intersect point by 2.5 min so...minimum 315 km? That doesn't account for MAVEN's own velocity at this point in its elliptical orbit, though.
