Darrell Jan, acting Life Support Branch Chief at NASA Ames Research Center, will present a seminar, “Life Support Air Processing Technology Development at Ames”, at the ASL on July 23rd as part of the ASL and Ames Bio and Syn Bio Talks Seminar Series. The event will be held in Building N239, Room B39 from 12:00-1:00pm.
Refreshments will be provided and you are welcome to bring your lunch.
Dr. Jan’s brief bio and an abstract of his talk follow below. Questions about this event can be directed to the POC, Peter Minogue.
Longer space missions require some means to remove Carbon Dioxide (CO2), which can then be used to recovery the oxygen. The CO2 Removal and Compression System (CRCS) is designed to perform both the CO2 removal function of the four-bed molecular sieve (4BMS) system currently employed on the International Space Station (ISS), as well as additional integrated ability to purify and thermally compress CO2 to supply downstream CO2 recovery units. The CRCS approach will reduce cost and improve reliability for future long-duration missions. This talk describes progress in CRCS development over the past year. Performance of the bulk air dryer (BAD) and residual air dryer (RAD) will also be discussed. A single unit of the 2-Stage Compressor was assembled and tested for development performance. Data from those tests was used in the assembly a second unit and integration into a two unit system.
About the Speaker:
Darrell Jan holds a BS in Bioengineering from UC Berkeley, and a PhD from MIT Department of Mechanical Engineering, where he performed research in the areas of cardio and pulmonary fluid mechanics. His doctoral thesis involved flow visualization in three dimensions using neutrally buoyant fluorescent particles that he made in the lab. His involvement with NASA started during his student days with a summer internship at JPL with the Viking Biology Team, and a co-op position at Ames Research Center in space suit development. Dr, Jan started at JPL in 1987. His fluid mechanics background first led him to work on rocket plume modeling. and propulsion system filtration, which involved particle flow analysis. He later worked on chemical and biological astronaut habitat sensors. During 1997/98 he was detailed to NASA Headquarters Code UL, where he served as Program Coordinator for the Advanced Environmental Monitoring and Control (AEMC) Program Element, part of the Advanced Human Support Technologies Program. Upon return to JPL he took the position of Group Supervisor for Planetary Protection Technologies. Soon after he became AEMC Project Manager and Deputy Manager for the NASA Biomolecular Systems Research Program in the Biological and Environmental Technologies Office of the Life Detection Science and Technology Program Office. As AEMC Project Manager, he was responsible for two JPL instruments which were flown on the International Space Station: the Electronic Nose (ENose) and the Vehicle Cabin Atmosphere Monitor (VCAM). In September 2012 Dr. Jan transferred to the Bioengineer Branch in the Biosciences Division of NASA Ames Research Center, where he took on responsibility for development of Air Revitalization technologies. The work focuses on sorbent technology development for removal of moisture and carbon dioxide. In 2013 he became acting Life Support Branch Chief which includes Water Reclamation and Waste Processing in addition to Air Revitalization.
