Did an Ancient Habitable Venus Provide the Seeds for Life Today?

Recent possible detections of Phosphine in the Venusian atmosphere [1,2] have spurred interest in the potential for life in the clouds of Venus given the limited number of abiotic alternatives determined thus far [3]. A number of theories have been posited as to how life could have arisen in the cloud decks of Venus (e.g. [4] and references therein) and how it might thrive in a supposedly hostile environment [5]. Over the past few years we have used forward modeling to investigate the possibilities of a temperate Venusian climate in its deep past. This affords us the opportunity to discuss the possibility for an early habitable Venus and its implications for habitability in the cloud layers today.

Seeding Innovative Ideas and Partnering with the Ecosystem

Jenn Gustetic will talk about how NASA selects ideas and collaborates with the ecosystem to develop new technologies for NASA’s portfolio. She will explain how the organization encourages collaboration, co-invests to develop ideas from lab to market, and acts as the hub-and-spoke of the ecosystem. Jenn will also discuss NASA’s journey to break silos and work horizontally across programs. • Gathering and evaluating ideas internally and externally with diverse players – engaging communities, being the hub-and-spoke of the ecosystem, and encouraging collaboration through co-investments • Identify the best ideas, funding ideas from maturation to hand-off with fluctuating budgets, and managing IP and tech transfer • Balancing investments in projects that address NASA’s needs with higher risk ideas that may not have an obvious application • Transitioning ideas to the next phase – training people and teams and ensuring ownership • Developing a 3.0 innovation capacity strategy – disrupting silos, enabling the ecosystem to work seamlessly together, and taking people and leaders along

Plasma Produced Gaseous Species for Food, Seed, and Equipment Sanitization

Researchers at KSC have shown that plasma produced gaseous species have shown greater than 5.89 log reduction of inoculated coupons and sanitization (greater than 3 log reduction) of produce and 3D printed materials, though with more variable results. The results were obtained using a recirculating plasma system, with 1 L of air, 1 mL of H 2 O, and less than 500 W of power being the only consumable commodities. The work is versatile and enabling for future missions since the air and the produced gases can be reused or recycled on board the spacecraft.
