Launch Period:
The orbiter launch period extended for 21 days, opening on April 7 and closing on April 27. The first 12 days of the launch period from April 7 to 18 make up what is considered the primary launch period; a secondary launch period runs from April 19 through 27. If Odyssey is launched during the secondary period, science data return at Mars may need to be reduced slightly because of higher arrival speeds and a longer aerobraking period. Arrival dates at Mars vary with launch dates, and range from October 17 to 28, 2001.
Daily Windows:
Two nearly instantaneous launch opportunities occur each day during the launch period. The pair of launch opportunities is separated by 30 to 90 minutes depending on the day. On April 7, the first launch opportunity is at 11:02 AM EDT and the second is at 11:32 AM EDT. The opportunites become earlier each day through the launch period.
