Collection and analysis of cometary dust during a rendezvous missionAn experimental program has been undertaken to investigate and develop methods for high-efficiency collection of dust particles during a rendezvous mission with a preselected comet. A laboratory apparatus has been designed and tested for acceleration of fine particles (0.1 to 100 microns) to velocities of 0.5 to 50 m/s. Tests of collection efficiency are being conducted under vacuum and with control of substrate temperature. Collection materials include filters, plastic films, metal foils, liquid metals, and sticky organic compounds. Results to date indicate that only certain materials will be adequate to meet collection requirements.
