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.

More than 90% of Americans believe that the US government is unduly influenced by money, and the Mayday.US super PAC is raising $5M to fund the election campaigns of politicians who’ll pledge to dismantle super PACs and enact other campaign finance reforms. They raised more than $1M in 30 days last month, and this month, the goal is $5M. It’s the brainchild of Lawrence Lessig, who’s going to run prototype the project by running five electoral campaigns in 2014, and use the lessons of those projects to win enough anti-corruption seats in 2016 to effect real change.
Again, I’m not able to contribute to Mayday.US, because I’m a Canadian and Briton. But I ask my American friends to put in $10, and promise that I’ll put CAD1000 into any comparable Canadian effort and/or £1000 into a comparable UK effort. We all win when countries embrace evidence-based policy guided by doing what’s best for its citizens, rather than lining the pockets of corrupting multinationals.

A reminder that those Doritos you love are trash:
Shortly after Disneyland opened in 1955, the founder of Frito-Lay got permission from Walt Disney to open a restaurant in Frontierland with a Mexican-ish theme. “Casa de Fritos” was, unsurprisingly, all about the Fritos. Customers got free Fritos, and Fritos were incorporated into many of the dishes. Fritos were dispensed by an animatronic vending machine that featured the terrifying “Frito Kid”asking his assistant “Klondike” to bring the bag up from a mineshaft. I guess the conceit is that Fritos were mined by Forty-Niners?
Casa de Fritos contracted their tortilla production to a company called Alex Foods. One of the salesmen from Alex Foods, making a delivery to Casa de Fritos, noticed stale tortillas in the garbage and gave the cook a little tip: fry them and sell them as chips instead of throwing them away. Casa de Fritos began making these fried, seasoned chips to enormous success, but didn’t report this new menu item to the Frito-Lay company.
Eventually Frito-Lay found out what they were doing with the chips, packaged them, and sold them by the truckload. See, dumpster diving works out sometimes!

Tales of temporary rejection from an organization not used to being ignored.
In IE10 and other new browsers one may create MessageChannel objects that have two MessagePorts each connected (w3c spec calls it entangled) to one another such that postMessage on one port results in the message event firing on the other. You can pass an array of ports as the last parameter to postMessage and they show up in the ports property of the message event arg.
The postMessage here is like the worker postMessage and unlike the window and iframe postMessage in that it applies no origin checking:
Unfortunately the origin isn't an optional parameter at the end to make the two postMessages have the same signature.
On the event handler side, the event arg always has an origin property. But in the no origin case it is always the empty string.
There is also a source property on the message event arg which if set is an object that has a postMessage property allowing you to post back to your caller. It is set for the origin case, however, in the no origin case this property is null. This is somewhat reasonable because in the case of MessagePort and Workers there are only two endpoints so you always know the source of a message implicitly. Unlike the origin case in which any iframe or window can be calling postMessage on any other iframe or window and the caller is unknown. So not unreasonable but it would be nice if the source property was always set for consistency.
When a MessageChannel is created it has two MessagePorts, but until those ports are started they will queue up any messages they receive. Once started they will dispatch all queued messages. Ports don't have to be started to send messages.
A port may be started in two ways, either by explicitly calling the start method on the port, or by setting the onmessage callback property on the port. However, adding an event listener via addEventListener("message", does not start the port. It works this way in IE and Chrome and the spec states this as well.
The justification is that since you can have only one callback via onmessage that once set you must implicitly be ready to receive messages and its fine to start the port. As opposed to the addEventListener in which case the user agent cannot start implicitly because it doesn't know how many event listeners will be added. I found Hixie stating this justification in geoloc meeting notes.
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.

How the 8.5” x 11” Piece of Paper Got Its Size
Why do we use a paper size that is so unfriendly for the basic task of reading? According to a very interesting post by Paul Stanley, the rough dimensions of office paper evolved to accommodate handwriting and typewriters with monospaced fonts, both of which rendered many fewer characters per line. “Typewriters,” he explains, “produced 10 or 12 characters per inch: so on (say) 8.5 inch wide paper, with 1 inch margins, you had 6.5 inches of type, giving … around 65 to 78 characters.” This, he says, is “pretty close to ideal.”
