Phase 1 of this study intends to leverage advances in laser optical trapping technology in order to study the feasibility of a system that could remotely capture a quantity of particulates over a period of time. These particulates would be delivered to instruments on a spacecraft or lander for continual analysis. Therefore, instead of recording data from one pass of an orbiter or being at the mercy of a solid sample inlet, scientists could choose their targets over a wider range, bringing significantly more value to planetary missions.
","benefits":"Our tractor beam research will focus on understanding and optimizing its ability to gently capture difficult targets such as these where other technologies currently available may prove to damaging to the targets. Adding a tractor beam system that could continuously, carefully, and remotely capture particles over a long distance could enhance the science goals and reduce the risk (driving down costs), which would therefore increase the value of all of these missions.

Planetary and interstellar missions such as Pioneer, the Viking Lander, and Cassini have relied heavily on in situ particle collection and analysis [1]. These and more recent instruments like Sample Analysis on Mars (SAM) on the Mars Science Laboratory (MSL), OSIRIS-REx, and Stardust have deployed several different in situ techniques such as Faraday traps, ablation and collection, or trapped matter in aerogel, yielding samples that are then returned to Earth [2,3]. Although these techniques have been successful, the type of particles that can be captured, how often the particles can be captured, the operational range of a lander, or the flight path of a spacecraft have severely limited available data sets. This coupled with instrument complexity and safety concerns can drive up costs and delay schedules. Innovative technologies are required to control costs and increase the viability and capabilities of critical particle collection and analysis missions. This proposal focused studying state-of-the-art laser-based tractor beams to determine their suitability for use on future Decadal Survey missions that require sample collection. Through the Phase I study we demonstrated that, though the technology is in its infancy, tractor beams do exist but can only move a limited number of targets over micron-level distances. Available technologies are not sufficiently developed such that they would be practical for future NASA missions. In the future, we hope to apply the most promising optical trapping technology, and develop a system that could remotely optically capture a quantity of particulates and transport them back towards the direction of laser propagation over a range of millimeters, while working towards achieving meter-scale operation. The captured samples will also need to be studied to understand the effect the trapping beam has on the particulates. For flight missions these particulates would be delivered to instruments on a spacecraft or lander for continued analysis. Therefore, instead of recording data from one pass of an orbiter or being at the mercy of a solid sample inlet, scientists could choose higher quality targets over a wider range and time period while simultaneously reducing risk and complexity, bringing significantly more value to planetary missions. If properly designed and implemented, a laser-based optical trapping system can fundamentally change the way scientist's design and implement NASA missions that require spectroscopy and particle collection.","infoText":"Closed out","infoTextExtra":"Project closed out","isIndirect":false,"infusionPretty":"Other","isBiDirectional":false,"technologyOutcomeDateString":"Sep 2012","technologyOutcomeDateFullString":"September 2012","technologyOutcomePartnerPretty":"","technologyOutcomePathPretty":"Closed Out","technologyOutcomeRationalePretty":""}],"primaryImage":{"file":{"fileExtension":"jpg","fileId":351624,"presignedUpload":false,"fileSizeString":"0 Byte"},"libraryItemId":351969,"description":"Project Image Laser-Based Optical Trap for Remote Sampling of Interplanetary and Atmospheric Particulate Matter","projectId":4369,"publishedDateString":"","entryDateString":"","libraryItemTypePretty":"","modifiedDateString":""},"libraryItems":[{"file":{"fileExtension":"jpg","fileId":351624,"fileName":"15126","fileSize":120349,"objectId":351969,"objectType":"libraryItemFiles","presignedUpload":false,"fileSizeString":"117.5 KB"},"files":[{"fileExtension":"jpg","fileId":351624,"fileName":"15126","fileSize":120349,"objectId":351969,"objectType":"libraryItemFiles","presignedUpload":false,"fileSizeString":"117.5 KB"}],"libraryItemId":351969,"title":"15126.jpg","description":"Project Image Laser-Based Optical Trap for Remote Sampling of Interplanetary and Atmospheric Particulate Matter","libraryItemType":"Image","projectId":4369,"isPrimary":true,"internalOnly":false,"publishedDateString":"","entryDateString":"01/22/25 01:10 AM","libraryItemTypePretty":"Image","modifiedDateString":"08/22/22 08:59 PM"}],"states":[{"abbreviation":"MD","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Maryland","stateTerritoryId":3,"isTerritory":false}],"endDateString":"Sep 2012","startDateString":"Sep 2011"}}
