Europa Report: Movie Review

I am always a fan of science fiction films and happy for any science fiction that comes my way. In this case Europa Report is a fairly independent movie that is being released online and On Demand before being shown in theaters. I recently watched this through my cable providers "Video On Demand" feature, where you can purchase a rental of this movie for $9.99 (ouch). There are both standard definition and high-definition versions available, but if you get one you don't get the other, so use with caution. I think releasing movies straight to the internet/on demand and skipping the theaters is a new strategy in the movie industry. Hear about that trend in this recent NPR: On Point broad cast: Is the U.S. Movie Industry Broken?

Europa Report is about a fictional manned-mission to Jupiter with a landing on the icy moon Europa. One of the four large "Galilean moons" of Jupiter, it has an icy crust, and as we all know, likely to have a sub-surface ocean of liquid water. This near-future sci-fi to stick closely to known technologies and science, might be what one would call "hard sci-fi", more 2001 than Star Wars. But actual science is not usually box-office dynamite (or so studios believe), so as the crew of 6 astronauts approach Europa they fall into increasingly critical misfortunes that threaten their mission and their lives. The movie is foreshadowed by an "executive" talking to the camera, documentary style about the mission and you get the sense something went wrong. Most of the movie is then shown through lost-footage style clips showing bits and pieces of the long journey and the events on Europa. This seems to be a common trope now as it is similar in the style to Apollo 18. Not only is the footage spliced together out of order so you don't get a full understanding of the events until later, but they use a lot of creepy noise effects and interference at times to make it seem "spookier" I guess. I still think Moon did the best job in recent years, to tell a story in space without devolving into a sub-genre of typical horror films, and just having normal drama in a science fiction setting (yes the premise for Moon isn't that realistic). In any case, I don't think it is a huge spoiler, given the trailers for this movie, to tell that things don't ultimately end well for the entire crew.

Other than the style, I found the characters and story were pretty good, the effects were pretty good overall and didn't seem like overuse of CGI and they did have some weightlessness scenes. The scenes in orbit around Jupiter and Europa were quite impressive, makes you wish we really were going there. There were no explosions in space, super AI, fusion reactors or any other really exaggerated technology. The ship had a rotating living section to simulate gravity which they spent most of their time in. Once they get to Europa they send a large section of the craft down as a lander which will then drill through the ice and hopefully reach the under-ice lake or ocean in order to search for life. That is the plan anyway.

Europa Report currently has a 69% fresh rating on Rotten Tomatoes. Overall I enjoyed the movie. It's probably worth a Netflix rental, rather than paying $9.99 for it.

spoiler alert!

 Stop reading if you don't want critical pieces of the movie spoiled for you.



While the Europa Report was pretty good, but the "science" part of the plot kept reminding me of List of things I did not care for in Prometheus. Basically it comes down to: "We are going to go halfway across the solar system, for the first time in humanity, but as soon as we get there we have no ability to actual get any scientific research done without being eaten by monsters". One the main claims to fame this movie has is the supposed realism and authenticity of the mission. I feel their hearts were in the right places, and it's basically a movie about every space geek's fantasy about what might be on Europa, but they fell into too convenient plot devices I found hard to swallow, despite enjoying the movie.

Among my issues with the plot:
  • No redundancy of communications... what!? Isn't that the most important thing for a mission to another planet/moon? Not to mention they apparently did have a way to repair it, but chose not to until the very end. Oh and genius idea that the life-support subsystem can swap parts with the communication subsystem.
  • No redundancy of their drilling probe? They lose one and all is lost. They can't improvise a camera on a pole and look under the ice?
  • Apparently, there was no firm plan to have the crew explore the ice surface after landing, no radiation protection, no way to deal with hazards of walking on ice, no vehicles to use other than walking. Why send humans at all in that case?
  • When they do send a scientist outside, they have no safety harnesses, they don't use a buddy system like mountain climbers (were the Apollo astronauts ever alone?). Let alone have any sort of a rescue plan i.e. a jet-pack or other person suited up ready to go out in an emergency. Maybe flotation devices might be useful on a planet with liquid water? For that matter, I wonder how buoyant a space suit is with low gravity, since I believe in those neutral buoyancy tanks on Earth they weigh down the suits with additional weight. She basically sinks like a stone in falling through the ice, they don't even bother to go after her, but it's implied she is eaten/killed by the monster. This is like horror movie 101 stuff, never go out alone, never walk towards the mysterious light.
  • So they go all the way to land on Europa and they don't have a reliable way to go outside, so you would think the lander would have all sorts of robotic arms, scoops and other sensors to get as much science, like any other lander NASA has ever sent to another world, but other than the one drill probe, apparently not. Wouldn't a major effort be to take back "Europa-rocks" of ice samples or whatever they can find and bring back to Earth for research?
  • You would think to support such a mission there would be a network of probes either in orbit around Europa or in the Jovian system which would be taking images of them and the landing site (maybe to see aerial view of the "lights" they are so desperate to see up close), able to relay communications, etc.. Like we have on Mars now with NASA's MRO
  • 6 crew all the way to Europa and only 2 scientists doing anything while they are there.
  • They didn't exactly explain how long they planned to live on Europa, similar to some missions to Mars, the return window is some length of time away, so they need to have some semi-permanent base to live and work out of for an extended stay. For Mars exploration there are ideas to send unmanned supply/cargo craft that would already be there on the moon for them to use to set up some sort of base. It didn't look like they had any plan like this, and it seemed like they had an all or nothing EVA to get scientific data before trying to come home? It wasn't clear if the rapid take off was due to the crew death's or because they weren't going to stay long anyway.

Maybe the idea (I doubt the writers even thought this far ahead) was that the mission was really just a "plant the flag" expedition to Europa, without much plan for hard science, but to promote the Europa Ventures company. Something like the quick and dirty ways they could get to Mars really fast without doing anything useful while there. But then again, they probably wouldn't need 6 crew for that. On the other hand, the one thing they did have redundancy for was the lives of the crew!


Some unresolved questions or plot points, and maybe I just missed them:

Why couldn't they leave theAndrei in the orbiter? Not that it mattered I guess, did they imply he had radiation poisoning or just that he was depressed?
 
Why did that male scientist die at the end, did he just fall because of an "ice quake" or did the monsters get him?
 
Hopefully the monsters' ecosystem isn't waiting for spacecraft to land, be attracted to their lights and fall through the ice so they can be eaten. They would get very hungry.
 
Wasn't the monster creature attracted to light almost directly taken from Arthur C. Clarke's "2061: Odyssey Three"?
 
It was implied that there was some connection between radioactivity interference and the monsters, could be interesting if there were alien life that could somehow use radiation in the environment directly as a food or heat source. But this was never really "answered" within the movie.

Windows Update Error code 80246007 on Windows 7

I have tried applying Windows Updates for .NET Framework security updates and was hitting failures on Windows 7 with error code 0x80246007. If I View the error details from Windows Update History I saw the following error codes:


For Windows update failure log (View Details):

Security Update for Microsoft .NET Framework 4 on XP, Server 2003, Vista, Windows 7, Server 2008, Server 2008 R2 for x64 (KB2804576)
Installation status: Failed
Error details: Code 80246007
...
Searching for this error on Microsoft Windows support site I only found the following KB article:
http://support.microsoft.com/kb/958042/en-us
Unfortunately, the article does not apply to Windows 7 specifically. Searching for the error code and Windows 7 brought up no additional results. What to do?


Disclaimer: I am not an expert on Windows system administration, I make no claims to be able to solve your individual problem nor advise you to not follow normal support paths for your issue. If you use any of my suggestions you do so at your own risk.

Reading the knowledge base article, the cause is described as:
This problem may occur if the Windows Update database is corrupted.

Under resolution there are the same steps to resolve for Window Vista and  Windows Server 2008. Broadly speaking, these OSes are similar to Windows 7 in many respects. So I attempted to follow the steps, which involve writing a small batch script to stop the Windows Update service,  wuauserv rename the Windows\SoftwareDistribution\Download folder and restart the Windows update and bits service.

I tried the instructions as described. Received access denied for every line of the batch script. I then tried running from a Command window I had 'Run as Administrator'.  I still got the access denied error on renaming the Download folder. So I just manually renamed via Windows Explorer, and reran the script.
 

The next time I ran Windows Update for the update which failed I then hit error 80070002 for one update.
This time Windows Help advised to delete data from Windows\SoftwareDistribution\DataStore as well as \Download folder, and to just restart Windows Update service.

This finally solved my issue. My guess is that these steps would apply to either 80070002 or 80246007 error codes on Windows 7.

I recommend if you hit this issue, to comment on the KB 958042 page above and let Microsoft know they need to update the KB for Windows 7.

New PC (again)

It's been a few years since I've gotten a new laptop. Realized it was about time as the screen on my old Toshiba began flickering white lines and generally acting up.

I got a new Sony Vaio S-series. This model is one of the few Windows 7 PCs that have a full HD resolution screen, 1920x1080. (I am envious of the MacBook Pro Retina displays). I looked at Windows 8 PCs as well, but couldn't stomach the "start" display, I wasn't interested in touch screen features.

Step 1: Transfer Files

I decided to try using Windows Easy Transfer, which advertises that it can transfer, "User Accounts, Documents, Music, Pictures...And More". My old laptop and the new laptop are both Windows 7 and come with Windows Easy Transfer pre-installed.

It's fairly straightforward, you start it on the source PC, and you get a pass key, start in on the new PC and you enter the pass key, once you do that you can choose what folders basically from the old computer you want to transfer. In my case I did a wireless connection. When you select a user account to migrate it pre-selects all their Documents, Pictures and Music libraries (under C:\users\.. ), for Shared files it selects Public libraries and also what appears to be any folder on C:\ that is not part of the default Windows install. This means a lot of garbage may be brought along from the old PC, it's not always clear on where programs store their files. Unselected the options for Program Data and Windows settings, I was unsure what files this would actually bring. In total I had 60+ GB of data to transfer.

After you select the folders and start the transfer the program on both PCs tells you not to use anything. I assume this is to prevent you from moving or changing files on either side during the move.

The transfer ran a full day before the new PC crashed giving me a helpful "Operating System Not Found" prompt. I had to restart that PC and there doesn't seem to be anyway to recover the state of the transfer. Worse, there isn't a report of the files moved, so I didn't really know what had completed. I could see most of the files on the new PC, and new it was almost done, so I didn't have to re-run the whole thing again. I just resumed from shared folders that I saw were missing.

One confusing thing was that it didn't actually transfer the Windows user accounts I had selected. It copied all the files from the old user accounts into my current user on the new PC (which happened to be a different user that I didn't want to keep). So you still have to manually set up any new users in the Control Panel.

Step 2: Install software
Basically I knew what I needed for my projects, Windows Easy Transfer also provided a report of all the software from the old PC that I didn't have. It's helpful as a reference.
 

Step 3: Fixes:
So far other than missing license keys and other things I had to dig through my email or memory to get back, one major issue was with Windows Live Photo Gallery. The the database that WLPG stores ratings and metadata (person, descriptive and geotags) for image formats that don't support it is not moved during the transfer.

Other people have had the same issue:
How to transfer image tags from Vista Photo Gallery to Windows 7 Live Photo Gallery

The ultimate answer involves some scary manipulation of the hard disk volume id, but ok:

Some helpful details about where WLPG stores files and it's database.

As I mentioned in my own experience of upgrading to Windows 7, I also transferred the old Windows Vista desktop backgrounds and user icons.
