| Approved by space ministers in 2005, the rover was supposed to be a fairly small venture costing no more than 650m euros. But as the project developed, it was decided the endeavour should be upgraded, to provide a bigger, more capable vehicle; and one that could carry a much broader range of science instruments. | Approved by space ministers in 2005, the rover was supposed to be a fairly small venture costing no more than 650m euros.

| However, the design boost also meant a huge jump in cost. The prime contractor, Thales Alenia Space, estimated the final price tag would be 1.2bn euros - and this was before instrument contributions from Esa member states were taken into account. | However, the design boost also meant a huge jump in cost.

| Italy, the lead nation on ExoMars, made it clear recently that it was not going to put any more cash into the mission; and with no other nations offering to make up the large shortfall in the budget, a delay became inevitable. | Italy, the lead nation on ExoMars, made it clear recently that it was not going to put any more cash into the mission; and with no other nations offering to make up the large shortfall in the budget, a delay became inevitable. |
| Because Red Planet missions are only launched when Earth and Mars are favourably aligned, the November 2013 departure must now slip to a January or February 2016 opportunity. | Because Red Planet missions are only launched when Earth and Mars are favourably aligned, the November 2013 departure must now slip to a January or February 2016 opportunity. |
| Europe's space ministers will meet in The Hague at the end of November, and will be told by officials that options will be sought to reduce the financial impact. One possibility is to ask the Russians and the US to take a greater stake in the mission. The US for example is currently funding the development of two instruments. | Europe's space ministers will meet in The Hague at the end of November, and will be told by officials that options will be sought to reduce the financial impact.

| The slight concern here is that the Americans have budget woes in their own Mars programme, with their next rover - the Mars Science Laboratory - also heading way over budget. | The slight concern here is that the Americans have budget woes in their own Mars programme, with their next rover - the Mars Science Laboratory - also heading way over budget. |
| The decision to delay ExoMars will come as a bitter blow to Europe's scientists. It is the biggest, most expensive robotic mission in the current timeline; and is the flagship venture of Esa's Aurora programme, its roadmap to explore the Solar System. | The decision to delay ExoMars will come as a bitter blow to Europe's scientists.

| Europe's only attempt to date to land on Mars, the Beagle 2 robot, was lost on entry to the Martian atmosphere in 2003. Europe's Mars Express satellite, which carried Beagle 2 to the planet, continues to return exceptional pictures and other remote-sensing data. | Europe's only attempt to date to land on Mars, the Beagle 2 robot, was lost on entry to the Martian atmosphere in 2003.
