This paper summarizes the science rationale and measurement objectives for MASCS, discusses its detailed design and its calibration requirements, and briefly outlines observation strategies for its use during MESSENGER orbital operations around Mercury.
His leadership as the principal investigator for GP-B advanced the GP-B program from the concept and technology development stages to the experiment's launch on April 20 , 2004 and its ensuing orbital operations.
However, the NEAR Shoemaker team wanted to attempt a landing after the year of orbital operations that consumed most of the remaining spacecraft fuel, operations funding, and planned Deep Space Network tracking.

"The second year of orbital operations will not be a simple continuation of the primary mission," he says.
It would globally map the lunar surface, measure the exosphere and plasma around the moon and carry out reconnaissance of landing sites for lunar exploration, exhibiting longtime orbital operations and global mapping.
At this point, orbital operations in the encounter phase will commence.
This research investigates angles-only relative navigation and closed-loop guidance algorithm for spacecraft mid-range orbital proximity operations when the orbital maneuver allows for range observability.
Freeman later wrote that during his 10th trans-orbital surgery, he called Watts to his office to assess the operation.
In our case, eyelid ptosis was aggravated after the orbital remodeling surgery, obstructing the visual field, so a secondary operation was performed after 3 months to correct the ptosis by levator muscle resection [ 14– 16].
