6/7/2017 San Diego, California Nearly three months of planning, preparation, and hard work have gone into this fateful day: Pegasus’s first plunge in salt water. From day one, when we opened our kit and started assembling our little ROV, the team has talked of almost nothing else. All of our hopes and aspirations rested on a successful first flight in salt water. In order to make sure everything went smoothly, we decided to test Pegasus in the shallow and protected waters of Mission Bay. On a cold and overcast Wednesday afternoon Project Pegasus team members set off on one of SDSU’s small boats, with the help of boat-handler extraordinaire (and fellow grad student/Edwards Lab mate) Tristin McHugh. We anchored in a shallow cove and prepared Pegasus for a fateful first dive. As it turns out, we experienced quite an emotional rollercoaster. All systems were a go; however, as we moved to drop our ROV in the water the camera image seized (much like our previous issue with the lasers). After rebooting the system, we tried again; and just like the first time just as we were about to drop Pegasus in the water the camera froze again. This happened not once, not twice but fives times! After our sixth reboot we decided to go for it… resulting in a flawless 35min dive! Our first “flight” of Pegasus took us on a tour of the murky water, through seagrass beds and around the boat. We quickly learned the nuances of a successful flight. As it turns out, Pegasus is a little heavy! Our negatively-buoyant ROV requires a lot of thrust to propel it through the water. We even learned what to do in the event of “entanglement” in environmental hazards, such as seagrass! After three months I’m delighted to say Project Pegasus is a success. I’m incredibly proud of all of the hard work, dedication, and cohesion displayed by Project Pegasus team members. We all learned a suite of skills along the way, adding new tools to our toolboxes. However, it’s now time to pack up Pegasus in preparation for the Edwards Lab’s second research expedition to the Aleutian Islands.
Stay tuned! There will be plenty of updates from the Aleutians. And when we get back in the Fall, Project Pegasus will meet again to discuss a whole host of new projects for Pegasus. Thanks for following us along this incredible journey! Cheers, Baron von Urchin
