One Step Closer to Mars with Aquaponics: Cultivating Citizen Science in K12 Schools

The Microbial Ecology and Biogeochemistry Research Laboratory at NASA Ames Research Center focuses primarily on the nutrient cycling and diversity of complex microbial communities. NASA is interested in the composition and functioning of microbial mat communities as these processes fundamentally shape the form and function of these analogs for the earliest forms of life on Earth (3.6 billion years ago), and likely will on other planets as well. Aquaponics systems are supported by microbial communities who perform many complex ecosystem services, including cycling nitrogen. Microbes are integral to the stability and productivity of aquaponics systems, which are analogous to microbial communities in food production systems that are essential for building efficient life support systems for long-distance space travel. Students at Meadow Park Middle School created 10 parallel aquaponics systems and took temporal microbial samples to characterize whether any macro-ecology variables impacted or changed the microbial diversity of these systems. Students additionally created a website so that other classrooms can pursue similar projects in their own schools (https://go.nasa.gov/2uJhxmF). Our lab at NASA Ames has sequenced water samples from each of the 10 tanks at 3 timepoints using a MinION sequencer. MPMS students will be involved in the analysis of the bioinformatics data generated through this collaboration. Our ongoing collaboration aims to collect and analyze data in the classroom setting that has utility for research scientists, while involving students as collaborators in the research process.

Citizen Science as a Tool for Scientific Research and Societal Benefit at NASA

NASA's strategic goals include advancing knowledge and opportunity in space and improving life on Earth. We support these goals through extensive programs in space and Earth science research accomplished via space-based missions and research funding. NASA's "system" is configured to conduct science using (1) in-house personnel and (2) grants, contracts, and agreements with external entities (academia, industry, international space agencies.

Surveying Outreach and Citizen Science Opportunities for Planetary Defense

Planetary defense stands out among the various topics of space science as an endeavour which the general public can understand, for which they can readily appreciate the value, and in which they can find significant relevance to their own lives. This is well illustrated in the extensive coverage that the international general media continues to give to the IAA Planetary Defense Conferences and their hypothetical NEO/Earth impact event scenarios. However, frequent doomsday predictions and bad movie plots illustrate that this is also an area for misinformation, misconceptions, and misunderstanding. In an endeavour as high-profile and critical as planetary defense, a campaign of accurate and effective public outreach is essential. In this presentation, we will survey some of the existing programs and opportunities that are particularly applicable to planetary defense outreach. This is done to stimulate discussion about how to best leverage existing resources and how to use lessons learned in creating new resources.

Citizen Science Twitter Data Management for Earth Science Applications

Social media data can provide useful real-time and historical information relating to the natural world, but managing this data poses challenges. Scientists at GES DISC are exploring the potential of Twitter data to augment precipitation data from the Global Precipitation Measurement (GPM) mission. However, the format of Twitter data is unconventional in the context of NASA data centers, resulting in frustration for scientists who need to work with the data. This study investigated procedures and standards needed to properly manage Twitter data to make them compatible with these data centers. After comparing databases, the study found that the MongoDB database was best suited for the storage of raw Twitter data due to its flexibility, ability to be accessed by multiple users, and querying functionality. The study used the Python package Zarr to transform processed Twitter data into a gridded format similar to that of satellite data. Each Tweet was mapped onto a time-space grid; each grid location contained information about Tweet attributes and precipitation. The study developed a pipeline for downloading, storing, and gridding Twitter data and transformed Twitter data into an understandable format for users of NASA satellite data.
