Folks familiar with JavaScript UWP apps in Win10 have often been confused by what PWAs in Win10 actually are. TLDR: PWAs in Win10 are simply JavaScript UWP apps. The main difference between these
JS UWP Apps and our non-PWA JS UWP apps are our target end developer audience, and how we get Win10 PWAs into the Microsoft Store. See this Win10 blog post on PWAs on Win10 for related info.
Web App
On the web a subset of web sites are web apps. These are web sites that have app like behavior - that is a user might call it an app like Outlook, Maps or Gmail. And they may also have a W3C app manifest.
A subset of web apps are progressive web apps. Progressive web apps are web apps that have a W3C app manifest and a service worker. Various
OSes are beginning to support PWAs as first class apps on their platform. This is true for Win10 as well in which PWAs are run as a WWA.
Windows Web App
In Win10 a WWA (Windows Web App) is an unofficial term for a JavaScript UWP app. These are UWP apps so they have an AppxManifest.xml, they are packaged in an Appx package, they run in an App
Container, they use WinRT APIs, and are installed via the Microsoft Store. Specific to WWAs though, is that the AppxManifest.xml specifies a StartPage attribute identifying some HTML content to
be used as the app. When the app is activated the OS will create a WWAHost.exe process that hosts the HTML content using the EdgeHtml rendering engine.
Packaged vs Hosted Web App
Within that we have a notion of a packaged web app and an HWA (hosted web app). There's no real technical distinction for the end developer between these two. The only real difference is whether
the StartPage identifies remote HTML content on the web (HWA), or packaged HTML content from the app's appx package (packaged web app). An end developer may create an app that is a mix of these
as well, with HTML content in the package and HTML content from the web. These terms are more like ends on a continuum and identifying two different developer scenarios since the underlying
technical aspect is pretty much identical.
Win10 PWA
Win10 PWAs are simply HWAs that specify a StartPage of a URI for a PWA on the web. These are still JavaScript UWP apps with all the same behavior and abilities as other UWP apps. We have two ways
of getting PWAs into the Microsoft Store as Win10 PWAs. The first is PWA Builder which is a tool that helps PWA end developers create and submit to the
Microsoft Store a Win10 PWA appx package. The second is a crawler that runs over the web looking for PWAs which we convert and submit to the Store using an automated PWA Builder-like tool to
create a Win10 PWA from PWAs on the web (see Welcoming PWAs to Win10 for more info).
In both cases the conversion involves examining the PWAs W3C app manifest and producing a corresponding AppxManifest.xml. Not all features supported by AppxManifest.xml are also available in the
W3c app manifest. But the result of PWA Builder can be a working starting point for end developers who can then update the AppxManifest.xml as they like to support features like share targets or
others not available in W3C app manifests.
This 30 day mission will help our researchers learn how isolation and close quarters affect individual and group behavior. This study at our Johnson Space Center prepares us for long duration
space missions, like a trip to an asteroid or even to Mars.
The Human Research Exploration Analog (HERA) that the crew members will be living in is one compact, science-making house. But
unlike in a normal house, these inhabitants won’t go outside for 30 days. Their communication with the rest of planet Earth will also be very limited, and they won’t have any access to
internet. So no checking social media kids!
The only people they will talk with regularly are mission control and each other.
The crew member selection process is based on a number of criteria, including the same criteria for astronaut selection.
What will they be doing?
Because this mission simulates a 715-day journey to a Near-Earth asteroid, the four crew members will complete activities similar to what would happen during an outbound transit, on location at
the asteroid, and the return transit phases of a mission (just in a bit of an accelerated timeframe). This simulation means that even when communicating with mission control, there will be a
delay on all communications ranging from 1 to 10 minutes each way. The crew will also perform virtual spacewalk missions once they reach their destination, where they will inspect the asteroid
and collect samples from it.
A few other details:
The crew follows a timeline that is similar to one used for the ISS crew.
They work 16 hours a day, Monday through Friday. This includes time for daily planning, conferences, meals and exercises.
They will be growing and taking care of plants and brine shrimp, which they will analyze and document.
But beware! While we do all we can to avoid crises during missions, crews need to be able to respond in the event of an emergency. The HERA crew will conduct a couple of emergency scenario
simulations, including one that will require them to maneuver through a debris field during the Earth-bound phase of the mission.
Throughout the mission, researchers will gather information about cohabitation, teamwork, team cohesion, mood, performance and overall well-being. The crew members will be tracked by numerous
devices that each capture different types of data.
Past HERA crew members wore a sensor that recorded heart rate, distance, motion and sound intensity. When crew members were
working together, the sensor would also record their proximity as well, helping investigators learn about team cohesion.
Researchers also learned about how crew members react to stress by recording and analyzing verbal interactions and by analyzing “markers” in blood and saliva samples.
In total, this mission will include 19 individual investigations across key human research elements. From psychological to physiological experiments, the crew members will help prepare us for
future missions.

This might be the strangest release of classic Chicago label Trax yet! The clue’s in the title - it’s Daft Punk brassified. We get four classics by the world’s most famous Gallic robot duo:
“Harder, Better, Faster, Stronger” gets turned into a 1940s Dick Tracy-style riff-off with every form of trumpet imaginable, “Around The World” mixes wind instruments with that famous vocal
mantra, “Da Funk” features plenty of sassy brass and “One More Time” wraps things up on a swingin’, jazzy high.
Bone conduction audio, retainers, and shiny hip-hop teeth grills aren’t new inventions, but tech hacker Aisen Caro Chacin had the clever idea to put them all together.
The Play-A-Grill MP3 player prototype fits in your mouth like a retainer, shines on the outside like a precious metal rap grill, and plays music through bone conduction through your teeth.
