After a journey of 400 million km, ESA’s Mars Express is now approaching
its final destination. On 19 December, the spacecraft is scheduled to
release the Beagle 2 lander it has been carrying since its launch on 2

At 9:31 CET, ESA’s ground control team at Darmstadt (Germany) will
send the command for the Beagle 2 lander to separate from Mars
Express. A pyrotechnic device will be fired to slowly release a loaded
spring, which will gently push Beagle 2 away from the mother

Data on the spacecraft’s position and speed will be used by mission
engineers to assess whether the lander was successfully released. In
addition, the onboard Visual Monitoring Camera (VMC) should provide
an image showing the lander slowly moving away. The image is
expected to be available mid-afternoon.

Beagle 2 will then continue its journey towards the surface of Mars,
where it is expected to land on 25 December, early in the morning.
At the same time, the Mars Express orbiter should be manoeuvring
to enter into orbit around Mars.

In view of the complexity of this operation, the Mars Express control
team has been trained to deal with the eventuality that separation
might not be achieved at the first attempt. If that did turn out to be
the case, there is a series of procedures that has already been set
up and tested for completing the manoeuvre successfully within
the subsequent 40 hours.

The "separation" event can be followed live at ESA/ESOC on Friday
19 December from 8:30 to 15:00. A videoconference will link the
control centre at Darmstadt with ESA Headquarters in Paris (F),
and ESA/ESRIN at Frascati (I). Media wishing to attend are asked to
complete the attached reply form and fax it to the Communication
Office at the establishment of their choice. [NOTE: Not attached – A.Y.]

straddling the relatively young northern plains and ancient southern highlands,
where traces of life could have been preserved.
