The missions that have been selected to date under the Explorer and Discovery programs and their status are summarized in Tables 2.1 and 2.2, which also include a brief description of the key science goals and accomplishments of each mission. The Explorer Program The Explorer Program is NASA's oldest flight program dedicated to science investigations -- Explorer 1 was launched January 31, 1958.

,3 SMEX, and MIDEX.4 The UNEX, SMEX, and MIDEX mission lines presently have cost caps of $15 million, $120 million, and $180 million, respectively, adjusted for inflation at the discretion of NASA depending on the circumstances of selection timing or delays. The cost cap for each of these mission lines has been adjusted over time with each new AO.

The remaining eight Discoveryclass missions were competed PI-class missions. The currently active Discovery missions include Stardust, 8The Aerospace Corporation supported the Discovery Program Office for a period of time between 1999 and 2003.

The New Frontiers rules are very similar to those of the Discovery Program except for the larger cost cap and the constraint that missions should launch within 4 years of NASA approval of the concept and preliminary mission design studies.10 Program management for New Frontiers resides within the joint Discovery/New Frontiers Program Office at MSFC. The Mars Scout Program The Mars Scout Program, which had its start following the post-Mars mission loss program reevaluation,11 has as its primary goal the launching of scientifically focused missions to Mars.

As mentioned above, some PIs run their projects in a hands-on mode and are as much technical managers as they are project scientists, interacting on a daily, if not hourly, basis with the hardware development effort. These PIs have typically gained experience by playing key roles in major instrument investigations on core missions or by leading major suborbital projects.
|
From page 23... ...
Much of the experience necessary for fulfilling project management responsibilities is available and can be obtained at a NASA center that routinely provides PMs for PI-led missions, an aerospace company that builds space hardware, or a government or academic laboratory with a history of delivering major instruments for missions. The supply of experienced PMs is, however, limited, and PIs must compete for a good PM (see the section "Proposing Team Experience and Leadership," in Chapter 7)
