Navy divers will practice an operational readiness training scenario about core drilling that lead to the collapse of a structure after an earthquake struck, thus causing debris to be spread out over a large area on the ocean bottom. US Navy dive teams will use rebreathers to set up the debris field, program search patterns for an Unmanned Underwater Vehicle that will survey the bottom to identify the debris, and use hand held navigation and sonar systems to find and recover the debris.

During NEEMO 22 a team of FIU marine scientists and astronauts from NASA, the European Space Agency and the Japan Aerospace Exploration Agency partnered with the Coral Restoration Foundation to create the world's deepest coral nursery 90 feet underwater. As coral reefs continue to decline it is more important than ever to study whether repopulating corals in deeper waters can be used to repopulate reefs in shallow water.

The 22nd NEEMO mission and 134th mission for Aquarius ended June 27 with “splashup” at 12:03 p.m. EDT, concluding another safe and successful mission. NEEMO's international crew is healthy, and all of their ISS, exploration and partner objectives for this mission were completed. (NEEMO 22 Status Report.)

Today marks the final day of operations before the crew begins their 15 hour 45 minute decompression back to surface pressure. This mission marks the 3rd year in a row that scientists from the Astromaterials Research and Exploration Science (ARES/XI) Division at JSC ARES has teamed with the lab of Integrative Marine Genomics and Symbiosis (IMaGeSLab) at FIU to assess the photosynthetic capability of corals and their genetic connectivity between deep and shallow reef corals.

Crew members returning to gravity after long duration spaceflight can have difficulty controlling balance and gait. Investigators from Johns Hopkins University have developed a portable measure of balance and motor performance (Resilience and Portable Sensorimotor Assessment Platform) using wireless sensors and software integrated with computer tablets. RAPSAP will integrate with measures of physiologic and sensorimotor function in an attempt to identify the mechanism responsible for the change.

During EVAs NASA is evaluating the role that an intra-vehicular (IV) support system can play during EVA. The IV Support System will utilize Marvin, an open-source digital timeline execution and life support system management tool that provides synthesized adjusting timeline status information and displays simulated spacesuit telemetry data. The associated IV workstation focuses on examining ways to minimize the amount of equipment required for operations, reducing space and launch mass needed.

Coral Restoration Foundation is teaming up with NASA and FIU for the second time to conduct research and build upon the long-term coral nurseries established at Aquarius during NEEMO 21. Research will include the comparison of growth, survival, and fitness of nursery corals grown at different depths. Ultimately, the coral colonies that are grown in the ARB nursery will be out-planted around Aquarius for long-term monitoring and throughout the Florida Keys to help restore threatened reefs.

Mission Day-4: NEEMO-22 - Aquarius is inspiring the next generation of researchers and explorers through innovative education and outreach programs that reach millions of kids globally. During this mission, aquanauts and topside education team members are hosting a number of Virtual Field Trips with schools around the world.

Weather is still limiting surface team support, but the aquanauts continue to work through mission objectives. The plan execution tool for this mission is Playbook, which is developed by NASA Ames Research Center and specifically designed for use by crew to support mission operations. Used as the primary mission operations tool, Playbook allows controllers and crew to see the mission plan and schedule changes in real-time or through fully simulated time-delay (NEEMO Status Report, 06/19/17).

Mission Day-2: NEEMO-22 - Although the weather has kept the surface team from working offshore today, the aquanauts press on without any adverse affects to their mission on the bottom. One of the main benefits of saturation diving from Aquarius. Mission Day-1: NEEMO-22 - Aquanaut team off the dock at 0830.
