A swing by manoeuvre will be performed by the 1,290-pound LCROSS and the 5,216-pound Centaur upper stage, at around 6 am on 23rd June. This will be done in order to calibrate the satellites science instruments and enter into a long, looping polar revolution around Earth and the moon. An approximated 37 days will be taken to complete a single orbit and these will be roughly perpendicular to the moons orbit. Sourcee
