geometry require no sample preparation, a factor important for in situ planetary measurements.<br />

A sample return container is being developed by Honeybee Robotics to receive samples from a derivative of the Champollion/<br />
ST4 Sample Acquisition <strong>and</strong> Transfer Mechanism or other samplers <strong>and</strong> then hermetically seal samples for a sample return mission.<br />
The container is enclosed in a phase change material (PCM) chamber to prevent phase change during return <strong>and</strong> re-entry<br />
to earth. This container is designed to operate passively with no motors <strong>and</strong> actuators. Using the sampler’s featured drill tip for<br />
interfacing, transfer-ring <strong>and</strong> sealing samples, the container consumes no electrical power <strong>and</strong> therefore minimizes sample temperature<br />
change. The circular container houses a few isolated canisters, which will be sealed individually for samples acquired<br />
from different sites or depths. The drill based sampler indexes each canister to the sample transfer position, below the index interface<br />
for sample transfer. After sample transfer is completed, the sampler indexes a seal carrier, which lines up seals with the openings<br />
of the canisters. The sampler moves to the sealing interface <strong>and</strong> seals the sample canisters one by one. The sealing interface<br />
can be designed to work with C-seals, knife edge seals <strong>and</strong> cup seals. Again, the sampler provides all sealing actuation. This sample<br />
return container <strong>and</strong> co-engineered sample acquisition system are being developed by Honeybee Robotics in collaboration with<br />
the JPL Exploration Technology program.<br />

The tunable ultrafast laser system with femtosecond <strong>and</strong> picosecond pulse capability <strong>and</strong> 1 kHz repetition rate has been purchased<br />
<strong>and</strong> installed. Equipment was acquired for ultrafast <strong>and</strong> photo-gated hole-burning studies of materials for frequency <strong>and</strong><br />
time domain spectral hole burning (SHB) optical storage. The goal is directed towards more efficient novel materials for SHB<br />
optical storage <strong>and</strong> photonics devices. Initially, the instrument has been used for measurements of the fluorescence decay time<br />
for several free-based <strong>and</strong> metallo-naphthalocyanines at temperatures 300 K <strong>and</strong> 8.5 K.<br />
