Ionic Liquid Biospheres
Sara Seager, William Bains, Iaroslav Iakubivskyi +4
Liquid is a fundamental requirement for life as we understand it, but whether that liquid has to be water is not known. We propose the hypothesis that ionic liquids (ILs) and deep…
Warm, water-depleted rocky exoplanets with surface ionic liquids: A proposed class for planetary habitability
Rachana Agrawal, Sara Seager, Iaroslav Iakubivskyi +6
The discovery of thousands of exoplanets and the emergence of telescopes capable of exoplanet atmospheric characterization have intensified the search for habitable worlds. Due to…
Astrobiological Potential of Venus Atmosphere Chemical Anomalies and Other Unexplained Cloud Properties
Janusz J. Petkowski, Sara Seager, David H. Grinspoon +7
Long-standing unexplained Venus atmosphere observations and chemical anomalies point to unknown chemistry but also leave room for the possibility of life. The unexplained observati…
Venus Life Finder Habitability Mission: Motivation, Science Objectives, and Instrumentation
Sara Seager, Janusz J. Petkowski, Christopher E. Carr +10
For over half a century, scientists have contemplated the potential existence of life within the clouds of Venus. Unknown chemistry leaves open the possibility that certain regions…
Mission Architecture to Characterize Habitability of Venus Cloud Layers via an Aerial Platform
Rachana Agrawal, Weston P. Buchanan, Archit Arora +8
Venus is known for its extreme surface temperature and its sulfuric acid clouds. But the cloud layers on Venus have similar temperature and pressure conditions to those on the surf…
Aerial Platform Design Options for a Life-Finding Mission at Venus
Weston P. Buchanan, Maxim de Jong, Rachana Agrawal +5
Mounting evidence of chemical disequilibria in the Venusian atmosphere has heightened interest in the search for life within the planet's cloud decks. Balloon systems are currently…
Venus Life Finder Missions Motivation and Summary
Sara Seager, Janusz J. Petkowski, Christopher E. Carr +10
Finding evidence of extraterrestrial life would be one of the most profound scientific discoveries ever made, advancing humanity into a new epoch of cosmic awareness. The Venus Lif…
Venus Life Finder Mission Study
Sara Seager, Janusz J. Petkowski, Christopher E. Carr +9
The Venus Life Finder Missions are a series of focused astrobiology mission concepts to search for habitability, signs of life, and life itself in the Venus atmosphere. While peopl…
Circular orbit spacecraft control at the L4 point using Lyapunov functions
Rachana Agrawal, Ravi N Banavar
The objective of this work is to demonstrate the utility of Lyapunov functions in control synthesis for the purpose of maintaining and stabilizing a spacecraft in a circular orbit…
