Extreme Close-Up of Mars's Moon Phobos

coondoggie writes "The European Space Agency's Mars exploring satellite will make a number of close-up passes of the Martian moon Phobos. The Mars Express, which the agency launched in 2003, has begun a series of flybys of Phobos, the largest moon of Mars, that will ultimately set a new record for the closest pass to Phobos — skimming the surface at 50 km, or about 31 miles. This is only about 5 times the irregular moon's average radius. The data collected by the satellite could help solve some of the mysteries about the moon, beginning with that of its origin."

      There was a 50 year old hypothesis that Phobos was hollow, with a very low density, in order to explain the anomalous drag on the satellite, which has now been shown to be due to the tidal bulge raised on Mars by Phobos. The measured density is about 1.9 gm/cm^3, which is a little low, but not unusual compared to the asteroids, especially small asteroids.

    I support science funding, but a billion dollars can fund a lot of terrestrial science projects, so any space mission better not be a stand-alone one as long as the budget stays so high. I agree putting a man on Mars isn't practical in the short term, but we should still be working towards making a Mars mission become practical. A data-gathering mission should have to fight directly with telescope projects for funding, otherwise it has to provide more direct benefits. For example, the article says it is planned to get samples back to earth by the 2020's. That mission would combine technical progress (getting something off of Mars for the first time) with scientific research, so it is an ideal project.

    As for this mission, knowing more about the composition of the moon can help us if we want to make use of it for future missions (for its gravity or as a base), and the mapping of the Martian surface will help us direct future missions. This is a good mission, and I support its funding. It isn't just about getting pictures of a rock.

This mission seems worth the cost, as it will help us plan future missions, but just as people shouldn't reject spending as soon as they see "space", we shouldn't automatically accept it either.
