lander to orbit around Europa. Several
launch systems could send the fourthstage booster, sky crane, and lander from
Earth to Europa. Figure 2 is a simple view
of one potential mission concept.
Planetary protection takes several
avenues. First, the lander must be sterilized before leaving Earth; we propose an
autoclave operation to sterilize the lander.
Then, the third-stage and fourth-stage
boosters and the sky crane must fly to destruction in Jupiter's atmosphere. These
operations should provide good measures
of planetary protection.
We used an iterative process to determine and propose the configuration for a
lander, spacecraft, and mission. Here is
the general method that we used:
1. Define the constraints and basic requirements.
Define the desired measurements.
Set the requirements for the measurements.
2. Select instruments that can make the measurements.
3. Determine the mission sequence of the instruments.
4. Calculate the mass, volume, and power consumption of the instruments.
5. Refine the requirements for the instruments, and repeat steps 1
through 4, as needed.
6. Calculate the cumulative totals for mass, power, and data volume of the instruments on the lander.
7. Determine the lander infrastructure needed to support the following:
Mechanical structure
Mechanisms and powered operations
Data storage and transmission
Figure 2.
Sequence of operations
8. Determine the final calculated lander structure and instrument
suite.
