1.3 Mission<br />

borne plat<strong>for</strong>ms can return images of more than a magnitude higher resolution than state-of-theart<br />

orbiting spacecraft. Near infrared spectrometry, crucial to detecting mineralogy on the planet,<br />

and high spatial resolution magnetometry, which may provide clues as to the origin of high<br />

crustal magnetism seen from orbit, require moving plat<strong>for</strong>ms. Being close to the surface also<br />

increases the resolution and sensitivity of these instruments. <strong>Final</strong>ly, atmospheric sampling can<br />

reveal variations over a much greater area. [182,49,175]<br />

The Entomopter concept provides a unique means of achieving flight on Mars without the constraints<br />

imposed by the environment on conventional aircraft. The Entomopter can fly slowly<br />

near the surface, land, and take off. This capability enables the Entomopter to accomplish missions<br />

that are not possible with fixed wing aircraft. The ability to land on the rocky surface of<br />

Mars enables the Entomopter to refuel, which greatly extends mission duration over that of conventional<br />

aircraft. The slow flight of an Entomopter with ground locomotion af<strong>for</strong>ds the possibility<br />

of landing on the surface of Mars to inspect objects and take samples, to rest during<br />

periods of communication blackout and adverse weather, and to harvest energy from the environment.<br />

Because of these unique flight capabilities a number of mission scenarios can be conceived <strong>for</strong><br />

an Entomopter vehicle system. Utilizing these capabilities with a variety of instruments, scientists<br />

can collect significant science data that would be impossible to acquire with any type of<br />

present-day exploration vehicle.<br />

1.3.2 Mission Architecture<br />

Based on the analysis done under the <strong>Phase</strong> I portion of the program, it was determined that utilizing<br />

the Entomopter in conjunction with a rover would return the most science date and provide<br />

the greatest flexibility. There<strong>for</strong>e, this architecture was established as the baseline mission<br />

profile.<br />

In this scenario, a rover containing two or more Entomopters lands on the surface. The rover and<br />

Entomopters leave the aeroshell-lander and begin to explore. The aeroshell-lander is a transport<br />

capsule and has no additional capabilities. The Entomopters communicate with the rover, which<br />

in turn relays the data to an orbiting communication system. The Entomopters can assist the<br />

rover in terrain navigation as the group slowly moves across the surface. The Entomopters<br />

would be able to dock with the rover <strong>for</strong> recharging; their range would be limited to the round<br />

trip distance to and back from the rover. This mission sequence is shown in Figure 1-10.<br />

The main advantage of this type of system is that new territory can be explored each day by the<br />

Entomopters as their home base, the rover, slowly moves along the surface. The rover would<br />

carry fuel to refuel the Entomopters after each flight. The mission would continue until the fuel<br />

within the rover is exhausted.<br />

A diagram of a potential mission scenario is shown in Figure 1-11. This figure represents four<br />

Entomopter flight vehicles flying to and from a rover. The flight-duration profile represents the<br />

flight and ground time <strong>for</strong> the Entomopter throughout the return trip to and from the rover. This<br />

is one example of the flight profile. The combination of ground and flight segments can be<br />
