NEEMO 14 Crew Journal,Mission Day 1

Took two glances at the sky as we bobbed behind the dive boat before splashing down. Last view of clouds and blue sky for two weeks.Then the team swam down and along the dive boat, until the Aquarius habitat loomed below us.

One’s first entry into the habitat is met with echoes and deep booming as you stand up out of the water in the metal entry lock. You’re standing in our entrance to the ocean, in a still pool that rises and falls with the surge at the ocean floor, rhythmically sucking the habitat air and burping it outside, or squeezing the air like a piston until your ears pop. The entry lock is a metal box adjoined to the living quarters – you climb a metal staircase to meet our hab techs Nate and James, who have spent most of the day preparing for our arrival.

We rinsed and dried off in a tiny shower at the top of the staircase, found our personal belongings in the small bunkroom, and after a quick lunch of nuts, canned meat, and tortillas, prepared for our first EVAs.

One is constantly distracted and amazed by the new sights and sounds. The view out the windows show a limitless blue, with passing fish always in your periphery. My head was on a swivel for the first few hours, unused to the movement and light in the windows.

You also hear clicking and snapping, like the popping of bubble-wrap, all around you. That’s shrimp and parrot fish feeding off the outside of the habitat.

After two “EVAs”, we are now well-fed and getting ready for the next day’s activities. More on the EVAs tomorrow.

What are dry runs and why are they an important part of Desert RATS?

Dry runs are  a critical aspect of any Desert RATS analog field test.  After the objectives of this years field test were established, each team went to work on their aspect of the project.  Engineers created solutions such as PUP, the Portable Utility Pallet.  This device has stowage space, geological evaluation tools, and even a wireless mesh network repeater.  As the field test approaches, each subsytem needs to be fully tested and evaluated.  Sometimes this is as simple as a functionality test, however it can expand into finding ways to improve durability, usability, and even things such as ergonomics.

Changes have also been made based on lessons learned from previous outings.  The new automated suit ports will simplify exiting LER.  Software such as the navigation system have been overhauled for ease of use and increased functionality.

In the end the goal is a successful analog field test.  This goal can only be met by insuring each subsystem has been integrated and tested.  Desert RATS is about working together to achieve a goal that is unreachable independent of each other.  Valuable lessons are learned here on Earth so that these systems are ready for the missions of the future.The Desert RATS is a NASA-led team of research partners working together to prepare for human-robotic exploration. This “working group,” led by NASA personnel, is comprised of both NASA and non-NASA Members.

The Desert RATS field test activity is the culmination of the various individual science and advanced engineering discipline areas year-long technology and operations development efforts into a coordinated field test demonstration under representative (analog) planetary surface terrain conditions. The purpose of the RATS effort is to drive out preliminary exploration operational concepts for EVA system requirements by providing hands-on experience with simulated planetary surface exploration extravehicular activity (EVA) hardware and procedures.
