Among the seven systems include, two control spacecraft functions such as position-keeping and data-handling, and five will manage functions on the satellite's scientific instrument.

在这七个系统中，两个用来实现控制太空船的功能，诸如定位和数据处理。其他五个用来实现卫星科学设备的管理功能。

It could mean they gain control of the spacecraft systems and can fire the engines, but after the orbit around Earth has dropped so low that there is not enough fuel to go to Phobos.

To do this the spacecraft will need fantastically accurate control systems: they will have to measure changes in the positions of the satellites with a precision of 20 picometres (a picometre is a millionth of a micron).
