NEEMO Underwater Astronauts Training Due to Begin

ESA astronaut Luca Parmitano is to lead NASA’s 20th underwater astronaut training mission this month.

Starting on 20 July, the 14-day NASA Extreme Environment Mission Operations sortie, or NEEMO, will see a team of four living and working in the Aquarius underwater research station off the coast of Florida, USA.

Luca’s crewmates will be NASA astronaut Serena Aunon, NASA spacewalk specialist David Coan and Japanese astronaut Norishige Kanai. For two weeks they will live and work almost 20 m underwater to test tools and techniques for spacewalks as they venture outside the base in full scuba gear, ESA wrote.

By adjusting their buoyancy, the aquanauts can simulate the gravity levels found on the Moon, Mars and asteroids.

Luca is an experienced spacewalker who ventured outside of the International Space Station twice during his six-month mission in 2013. His second spacewalk was cut short as water built up in his helmet from a problem in his spacesuit.

Luca commented on the announcement of his commanding role for this year’s NEEMO: “Astronauts and a lot of water – my kind of environment!”

Last year ESA astronauts Thomas Pesquet and Andreas Mogensen spent time underwater and this year’s NEEMO will continue to find ways to improve coping with communication time delays due to the distance of potential destinations.

The aquanauts will further test ESA devices. A wearable ‘mobile procedure viewer’– mobiPV – gives astronauts mobile access to hands-free instructions with audio and video that only they hear and see, while mission control looks over their shoulder and offers advice.

You could say that this underwater test of mobiPV is a rehearsal for the version that will fly to the International Space Station in September for Andreas Mogensen’s mission,” explains ESA’s Mikael Wolff.

Luca and his colleagues will test mobiPV by running the Skin-B experiment.

UTC 2017

The subsea industry has, as all other parts of the oil & gas industry, been seriously rattled by the most severe downturn in the hydrocarbon energy era. However, the realization of what hit us and actions to be taken to sustain a healthy and profitable future is still on-going – unfortunately with thousands of colleagues paying the price by losing their job as one of the most severe consequences. At this time, there are signs that we have reached bottom in terms of most industry indicators, but few experts expect a sharp recovery. Many seem to believe that a slow recovery is what the industry needs in order to avoid an unsustainable capacity build-up, as seen in the period after the financial crisis. Considering the uncertainty of what the future will bring, this year’s UTC Program Committee have decided to challenge all of us to present ideas, experiences, technological innovations, business models and execution models for how to shape our subsea future and explain how and why subsea is the future.
UTC welcomes abstracts based on the topics listed below. If selected, please consider writing a paper in addition to the UTC presentation. From 2017, UTC papers will be published in an international database.
