Goddard Space Flight Center Avoid pointing the +V1 axis within 15 degrees of bright earth limb from the time HST is released by the Orbiter through release +3 days. Constraint satisfied. 2. Avoid pointing the +V1 axis within two degrees of the bright earth limb from release +3 days through release +12 days. Constraint partially satisfied. Total of <6 min. exposure during last 8 orbits of BEA on day 12, due to risk in slewing during to PCS high-voltage stand-down. 3. From release +12 days through release +42 days the cumulative exposure of the focal plane to the earth (+V1 axis within two degrees of the bright-earth surface) is not to exceed the total bright earth exposure (approximately six days) experienced by HST during the first six weeks following the Second Servicing Mission. Constraint satisfied. Total of 4.83 days of B.E. exposure.
