Oh you have such a dirty mind! NASA's MAVEN, a Mars science package, will enter the Martian atmosphere at an altitude of 236 (what wildly accurate shooting huh?) to begin a 33 minute deceleration burn that will consume more than half of the on-board fuel carried by the satellite. This combination of atmosphere and engine burn will insert Maven into a 35 hour capture orbit.
MAVEN will then begin a calibration phase a part of which includes maneuvering the spacecraft into its final 4.5 hour orbit. During this period, controller, will test its instruments and science-mapping commands. After-which MAVEN will begin its one-Earth-year mission to take measurements of the composition, structure and escape of gases in Mars’ upper atmosphere and its interaction with the sun and solar wind.
