It included the solar array deployment, the initial attitude acquisition, the declamping of the Beagle-2 spin-up mechanism, the injection error correction manoeuvre and the first commissioning of the spacecraft and payload (final commissioning of payload took place after Mars Orbit Insertion).
The instruments that operate at low temperatures to be kept cold are thermally insulated from this relatively high internal temperature, and emit excess heat into space using attached radiators.The spacecraft is run by two Control and Data management Units with 12 gigabits Please update this article to reflect recent events or newly available information.Announcement by the European Space Agency on the launch of the
Initially, Mars Express also carried a small lander called Beagle 2, named for the ship in which Charles Darwin set sail to explore unchartered areas of the Earth in 1831.
Media representatives are invited to a briefing at ESA’s operations centre in Darmstadt, Germany on Monday 3 June, marking the tenth anniversary of the launch of ESA’s Mars Express.
All the different experts had to work together in an operational environment and the interaction and interfaces between all elements of the system (software, hardware and human) had to run smoothly for this to happen:
For more than 20,000 orbits, Mars Express payload instruments have been nominally and regularly operated.
The Flight Control Team currently consists of:
On the technical side, it has been made possible (among other reasons) thanks to the adoption of both Agencies of the Standards for Space Communications defined in Thermal control is maintained through the use of radiators, The spacecraft is covered in gold-plated aluminium-tin alloy thermal blankets to maintain a temperature of 10–20 °C inside the spacecraft.

The payload was mostly switched off during the cruise phase, with the exception of some intermediate check-outs. Although it was originally meant to be a "quiet cruise" phase, It soon became obvious that this "cruise" would be indeed very busy.

Examples of discoveries - still debated by scientists -- by Mars Express are evidence of recent glacial activity, explosive volcanism, and methane gas.

All of the instruments take measurements of the surface, atmosphere and interplanetary media, from the main spacecraft in polar orbit, which will allow it to gradually cover the whole planet. History at your fingertips

The payload was checked out one instrument at a time.
The orbit was later adjusted by four more main engine firings to the desired 259 km × 11,560 km near-polar (86 degree inclination) orbit with a period of 7.5 hours.
Each of these teams focussed on the area of its responsibility and interfacing as required.
A major additional requirement raised for the Launch and Early Orbit Phase (LEOP) and all critical operational phases was that it was not enough merely to interface; the teams had to be integrated into one Mission Control Team.
