Probe to make closest flyby of Mars moon tomorrow

On Sunday, the European Space Agency's (ESA) Mars Express will make the closest flyby yet of the Red Planet's largest moon Phobos, skimming past at only 45km above its surface, the space agency said.

The flyby will be so close and fast that Mars Express (launched on June 2, 2003) will not be able to take any images, but instead it will yield the most accurate details yet of the moon's gravitational field.

According to ESA, as the spacecraft passes close to Phobos, it will be pulled slightly off course by the moon's gravity, changing the spacecraft's velocity by a few centimetres per second. These deviations will be reflected in the spacecraft's radio signals as they are beamed back to earth, and scientists can then translate them into measurements of the mass and density structure inside the moon.
