Astronauts Conduct Latest Plant Water Management on the International Space Station
NASA recently performed the sixth iteration of the CSS-supported Plant Water Management experiment on the International Space Station (ISS). Plant Water Management is a series of technology demonstrations focused on developing a capability for crop irrigation and nutrient delivery in various microgravity environments. NASA’s ISS Research Program selected CSS through its Research, Engineering, Mission, Integration Services (REMIS) contract to serve as the prime contractor for performing all mission integration and operations for the plant water management system. CSS’ role as the integrator and project manager for this effort includes designing, testing and manifesting the hardware, processing all safety related items, coordinating procedures, turning over the hardware to NASA for delivery to the International Space Station, and supporting real-time experiment operations on ISS.
The experiment payload, which includes a hydroponic system powered by a pump, a variety of induced perturbations, and synthetic plants that mimic various plant root systems, has been delivered to the International Space Station where the crew of Boeing astronauts currently resides. The crew volunteered to support this science experiment testing the hydroponic process of growing plants in their intended microgravity environment.

Although the astronauts volunteering to run the experiment admit they were first skeptical about running a hydroponic system with artificial plants, they then realized the value in testing the system. After running the operation for three days, they expressed amazement in the complex science needed to pump water through the system.

Continued Analysis of Contaminants from East Palestine Train Derailment
In February 2023, a freight train carrying hazardous materials derailed in East Palestine, Ohio spilling chemicals that contaminated surrounding soil, water, and the air. Several Portable High-throughput Integrated Laboratory Identification Systems (PHILIS) – the U.S. Environmental Protection Agency’s (EPA) suite of mobile laboratories designed to provide on-site analysis of chemical agents – and staff were mobilized to the site following the accident to conduct analysis of various contaminated media. The CSS…
