THE TRANSIT OF
SYNTHETIC ASTROBIOLOGY |
|
ABSTRACT
Astrobiology revolves around three central questions: "Where do we come from?", "Where are we going?", and "Are we alone?" The Stanford-Brown iGEM team explored synthetic biology's untapped potential to address these questions. To approach the second question, the Hell Cell subgroup developed BioBricks that allow a cell to survive harsh extraterrestrial conditions. Such a toolset could create a space-ready synthetic organism to perform useful functions off-world. For example, the Biomining branch attempted to engineer bacteria to recycle used electronics by degenerating silica and extracting metal ions in situ. The Venus Life subproject grappled with the third key astrobiological question by exploring Carl Sagan's theory that life could exist in Venusian clouds. To this end, Venus Life designed a cell-cycle reporter to test for growth in aerosol within an adapted Millikan apparatus. Through this triad of projects, Stanford-Brown iGEM aims to illuminate synthetic biology's value as a tool for astrobiology. |
ACCOMPLISHMENTS
|
Surviving in the harsh conditions of space is not easy for an organism. Extreme temperatures, desiccation, and pressures are only some of the problems an intrepid bacterium might face on its journey. We hope to equip our organisms with the ability to live and thrive in space, and maybe even Venus! |
The surface of Venus is harsh and unforgiving. However, research suggests that there may be layers of its atmosphere that are more temperate. We aim to see whether or not it is possible for bacteria to survive and replicate in an aerosolized environment, and then put our Hell Cell to the test! |
If we are to colonize space, we are going to need rare metals for materials. But bringing the heavy duty equipment for traditional mining is not very viable at all! Bacteria and other biological organisms can be used to extract rare metals from sediment. Bacteria could mine asteroids and do all the work for us! |
