The main engine burn lasted around 50 minutes and decelerated the spacecraft by approximately 1251 ms-1 (~ 4500 kmh-1).
The spacecraft intially entered a highly elliptical polar orbit with a pericentre of 400 km, an apocentre of 350 000 km and a period of 9 days.
To achieve the final operational orbit a series of necessary correction manoeuvres was performed:
|15 April 2006||Pericentre Control Manoeuvre #1||5.8|
|20 April 2006||Apocentre Lowering Manoeuvre #1||199.9|
|23 April 2006||Apocentre Lowering Manoeuvre #2||105.3|
|26 April 2006||Apocentre Lowering Manoeuvre #3||9.2|
|29 April 2006||Apocentre Lowering Manoeuvre #4||8.0|
|2 May 2006||Apocentre Trim||2.0|
|6 May 2006||Pericentre Control Manoeuvre #2||3.1|
