Here I dip into the NASA experience of and rules for Extravehicular Activity, prompted at first by watching a film called The Europa Report, directed by Sebastian Cordero (2013).
WARNING - THIS PODCAST CONTAINS SPOILERS
While I have some gripes about the film, I was impressed by its general failfulness to the science
Science consultant on the film was Kevin Hand, an astrobiologist and expert on Europa at NASA's Jet Propulsion Laboratory
To my mind, the scientists were behaving like scientists and the engineers behaved like engineers. To follow along it might help to recall their names
All was going scientifically until the director drove the plot forward with two EVA incidents
I have problems with this because it's just too clumsy for trained professional astronauts. Where are the decontamination procedures, the tethers, the special tools?
With this I am shouting at the screen "No Way! Where's the fracking operating manual? No one goes EVA on their own"
So, that is why I researched the NASA rules for Extravehicular Activity. And I found that none of these events would have happened the way they were shown, had the crew, who were so professional in every other way, followed the NASA procedures.
NASA documents on the internet discuss in exhaustive detail all considerations for EVA. What I present is a cherry-picked handful. I could not cover all of it
Although this podcast is about EVA, it does reference the science in a film that I enjoyed and respect very much, so here is a gem that I only came across while researching the landing site. In the scientific journal Nature, Volume 479, 16 November 2011, Britney Schmidt et al, of University of Texas, Austin, published a paper titled "Active formation of 'chaos terrain' over shallow subsurface water on Europa." In the paper these authors suggest that in the Conemara zone of the Chaos Terrain, an area on the surface of Europa, the ice may be as little as 3 km thick. Then in the film the Conemara Chaos was the targetted landing zone and the drill broke through the ice at a depth of 2800m.
Well there is one more thing that the podcast says, but it is the ultimate spoiler. So if you have not already listened to the podcast, I highly recommend that you watch the film first.
