It's Phobos season again for Mars Express
The Mars Express blog has been reactivated today, as a new series of Phobos flybys is already underway. Mars Express gets a series of 10 to 12 reasonably close flybys of Phobos once every five months, and is the only orbiter currently at Mars that can see the "far side" of Phobos. Mars Odyssey and Mars Reconnaissance Orbiter can only see Phobos' Mars-facing hemisphere, because those two orbit much closer to Mars than Phobos does.
