The voice of the machines.

As I've commented in past postings, the 30% off coupons from Meta (né Oculus) are a clever tool for developing and maintaining customer engagement in the nascent VR marketplace. My most recent coupon purchase of choice was Vox Machinae*, from Vancouver-based indie developer Space Bullet Dynamics**, and after a relatively short trial period, I have to say that it's easily the best VR experience that I've had on the Quest 2 platform to date.

Actually, I should qualify that. Star Wars: Tales from the Galaxy's Edge is undoubtedly an excellent VR experience, but it's hard to avoid a touch of motion sickness as you hop from location to location, and that tends to disturb the illusion. For whatever reason involving the game's dynamics, I've had much less of a problem with Vox Machinae, which makes a huge difference in the playability of the game. 

In the universe of Vox Machinae, you're the pilot of a 25 meter*** industrial mining robot called a Grinder, which can be equipped with a variety of weaponry in order to fight off corporate raiders - apparently business is a little more competitive in this version of the future. The armoury options range from lasers and missiles to old-school kinetic impact cannons, and your Grinder also has limited flight capability, but you need to be careful in terms of how you utilize these options so that your chassis doesn't shut down from overheating and render you immobile and helpless. 

Vox Machinae was originally released as a PC game in 2018, and based on what I've seen online, the VR build doesn't have the same resolution quality as the desktop version of the game - which is a shame, I gather the PC landscapes are beautifully rendered.  Regardless of the number of pixels involved, I found that the degree of VR immersion in the game was so complete that in the heat of combat, it doesn't feel like a VR experience, it feels like actually operating a giant robot on an alien battlefield.  

 

The Grinder cockpit is detailed and complex, and I was impressed to discover that I had the option of actually adjusting the position of the info screens by moving them with my virtual hands. Grinder movement is controlled by two virtual joysticks, one of which controls speed and the other direction, and there's a lever option for flight.  Weapon fire is managed by buttons on the Quest controllers, and if things go very badly, hopefully you can pull the EJECT handle located between your legs at the last minute before your Grinder explodes.  In my first attempts at combat, I didn't understand which hand controller buttons activated the secondary weaponry, but once I had that established, my combat survival times went up considerably.

After my initial tutorial outing with my Grinder, I was almost disappointed to realize that there's a storyline attached to the game. I actually didn't have any desire to establish my psych profile by interacting with the rest of my team or anything similar, I just wanted to fight against other mechs.  Also, the character drawing and animation isn't particularly good - generally I've found this to be the case for most of the VR games I've purchased, but based on what I've read online, the PC version suffers from the same weakness.

Fortunately, there's an arena option which allows you to go up against bot opponents - it also supports Player Versus Player with other humans, but sad to say, I don't actually know 15 other people who would want to pilot a giant warbot in virtual life-or-death combat. At least, I don't think I do - if there are closet mecha fans in my social circle who are reading this, send me a text, we'll talk!

* I'm not sure about the validity of this in actual Latin. Depending on where you look online, machinae is either an acceptable plural for machina, or it's machinarum, but then, as Eddie Izzard points out, Latin is a silly billy language.

** Come to think of it, a substantial percentage of the Oculus games seems to be from indie developers, I wonder if VR game creation just isn't viewed as a lucrative growth marketplace by the major players such as Bethesda or Blizzard.

*** For whatever odd reason, the marketing people at Space Bullet seized upon Tyrannosaurus Rex as the unit of measurement for Grinder size. The robots are described as being "seven time taller than a T. Rex", which seems to be a bit of a moving target in terms of scale depending on whether you're looking at dinosaur height or length, but since Wikipedia indicates that T. Rex height is about 3.5 meters, we're going to go with that as our yardstick.

That '70s Show.

With tomorrow's launch of NASA'S Artemis I mission, we will see the long-awaited renewal of the American human-based space exploration program. 

Well, not exactly.  Without the pressure of trying to beat the USSR to a Moon landing (although they're keeping an eye on China, apparently) NASA is taking a more careful approach this time.  Artemis I is a 42-day unmanned mission that will orbit the Moon, launch ten compact Cubesats en route, and return.  Artemis II, scheduled for early 2024, will take four astronauts (one Canadian) on a similar flight plan around the Moon, and Artemis III will land the first woman at the south polar region of the Moon in 2025, along with a male astronaut. The eventual goal is to establish a permanent presence in the form of a lunar base - Moonbase Alpha, if you will.  

NASA also plans to start assembly of its Gateway lunar space station in 2024, with the intention of the Artemis III crew being able to make use of new station. However, if there are any delays in the construction schedule, Artemis III will not need to rely on Gateway to complete its planned mission.

The sad thing is that even though it's been not quite 50 years* since the last lunar landing, NASA is using almost exactly the same non-sustainable approach to space exploration that it used then. Given the delays in project completion** and the cost overruns, I was surprised to learn that the Space Launch System, successor to the legendary Saturn V rocket used for the Apollo missions, uses four RS-25 engines that were literally recycled from the space shuttle program, as was the Orion 1 main engine.  Sadly, this will be their last mission: apparently NASA decided that recovering any of the parts from the core stage of the SLS wasn't feasible.  Similarly, the twin booster rocket sections contain components from the shuttle program, but once again, they will not be recovered.

It seems odd that NASA has taken this approach to the Artemis program, given that SpaceX has been quietly transporting cargo to the ISS since 2012 - and crew since 2020 -  using reusable components such as boosters that land on floating rafts, and the Dragon cargo and crew modules that are salvaged and refurbished for additional missions.  Just to clarify what this means in practical terms, SpaceX charges NASA $67M USD per launch (they've just raised the price from $62M, apparently everyone is suffering because of the supply chain).  

Artemis I$23 BILLION TO BUILD AND ANOTHER $4.1 BILLION DOLLARS*** for tomorrow's launch - and it will only fly once.   Sigh...  NASA, the '70s called, they'd like their rocket back.

* December 19th, 1972.

** The first SLS launch has been delayed a staggering 15 times since 2010 - I did a blog posting in 2019 with a more optimistic timeline for Artemis than the eventual result.

*** These number comes from The Daily Mail website.  NASA announced in 2017 that it wouldn't be giving cost-per-flight estimates for the SLS, which has to say something about how much it costs.

UPDATE:  The launch was cancelled due to engine problems and is being rescheduled  - well that can't be good...
